WEBVTT 00:00.080 --> 00:01.560 Let's create some traps. 00:01.600 --> 00:03.720 Game object basically traps. 00:03.720 --> 00:06.600 To do that, I'm going to head over to my project app. 00:06.600 --> 00:07.600 Then assets. 00:07.600 --> 00:12.880 I will head over to my sprites folder, then Pixel Adventure one folder. 00:12.880 --> 00:14.120 So just wait a minute. 00:14.520 --> 00:16.480 I'm going to make this like this. 00:16.480 --> 00:18.880 And let's move over to sprites folder. 00:19.160 --> 00:25.960 Then Pixel Adventure one folder and I have three folder inside there sub folder. 00:26.160 --> 00:30.160 And let's go to traps and let's select the sofas. 00:30.240 --> 00:32.640 So we're going to deal with the sofa first. 00:32.640 --> 00:34.840 So let's select the sprite sheet. 00:34.840 --> 00:36.160 Let's go over to Inspector. 00:36.160 --> 00:39.280 Let's click on this open Sprite editor editor. 00:39.520 --> 00:41.560 So let's slice this individually. 00:41.560 --> 00:46.000 So pixel per unit we're going to choose 16 filter mode to point no filter. 00:46.000 --> 00:49.920 And then click on this apply button and make sure sprite mode to multi. 00:49.960 --> 00:52.720 Because we're going to slice individually. 00:53.160 --> 00:57.800 Instead of slicing automatic we're going to move over to our Sprite Editor tab. 00:57.800 --> 01:02.100 Let's click on this slice and we're going to select automatic to read by cell count. 01:02.100 --> 01:04.980 And let's count how many columns and rows we have. 01:05.020 --> 01:08.060 We can see one row and four columns. 01:08.060 --> 01:11.100 So we're going to put eight columns and one row. 01:11.260 --> 01:15.900 And after doing that let's click on this slice button and then click on this apply button. 01:15.900 --> 01:18.260 And I'm going to choose my game view once again. 01:18.300 --> 01:20.180 And let's go over to that spreadsheet. 01:20.180 --> 01:23.500 Click on this arrow in order to see the individual sprite. 01:23.660 --> 01:29.900 And in the bottom right you can see in your project tab you can just scale this up like this. 01:30.260 --> 01:31.940 It's up to you basically. 01:32.260 --> 01:34.140 So I'm going to select the first sprite. 01:34.140 --> 01:37.580 Let's drag it over to the scene view or into this hierarchy. 01:37.580 --> 01:38.940 So I'm going to select that. 01:38.940 --> 01:42.300 Let's drag it over to the scene view or into this hierarchy. 01:42.460 --> 01:45.300 As you can see we have our shop. 01:45.500 --> 01:47.340 So let's call it something like shop. 01:47.340 --> 01:51.540 So let's go over to Inspector and let's call this one store. 01:51.780 --> 01:56.260 And we're going to add some some components to this shop game object. 01:56.260 --> 02:01.960 First thing we're going to add a rigid body 2D and we will set the gravity scale to zero, so it's not 02:01.960 --> 02:03.520 gonna fall down at all. 02:03.720 --> 02:09.840 Second, uh, second component we're gonna add a circle collider 2D for collision detection. 02:10.040 --> 02:12.200 So let's click on this add component. 02:12.200 --> 02:16.040 But before you do, make sure you select your GameObject in the hierarchy. 02:16.240 --> 02:19.760 Then go over to Inspector and then click on this add component. 02:19.960 --> 02:22.160 And we're gonna add a rigid body 2D. 02:22.160 --> 02:24.760 So let's type that and it's going to pop up. 02:24.960 --> 02:30.320 And as soon as it's gonna pop up we just gonna click on it in order to attach that. 02:30.320 --> 02:32.840 And now we're going to set the gravity scale to zero. 02:32.840 --> 02:36.600 So let's set this to zero and collision detection. 02:36.600 --> 02:40.240 We're gonna choose continuous and interpolate to interpolate. 02:40.400 --> 02:43.280 And we can freeze the rotation about z axis. 02:43.280 --> 02:45.280 Or we can just skip it that. 02:45.480 --> 02:50.040 So now let's click on this rigid body one more time just to collapse at once. 02:50.040 --> 02:52.160 And let's click on this add component. 02:52.160 --> 02:55.040 And now we're going to add a circle Collider 2D. 02:55.040 --> 02:57.680 So let's type that circle Collider 2D. 02:58.040 --> 03:03.060 Or we can just go over to, uh, Collider 2D and we can just add that up. 03:03.060 --> 03:11.340 So let's attach this circle, Collider 2D, and we need to adjust the collider as the size of our sprite. 03:11.340 --> 03:15.380 So we're going to move over to Inspector and then click on this Edit Collider. 03:15.380 --> 03:18.580 I just want to make the radius a little bit smaller. 03:18.580 --> 03:23.780 So I'm going to move over to my radius uh inside this circle Collider 2D component. 03:24.060 --> 03:28.420 And let's make it something like 11.1. 03:28.420 --> 03:30.180 Let's make it 1.1. 03:30.180 --> 03:31.140 And then Simms. 03:31.140 --> 03:31.860 Perfect. 03:31.860 --> 03:34.100 And we're going to assign this circle Collider. 03:34.140 --> 03:39.260 Sorry this game object as a trap game object since this is going to be a trap. 03:39.260 --> 03:44.300 So that's why we're going to assign this so game object as a trap tag. 03:44.340 --> 03:46.620 To do that we will go over to Inspector. 03:46.620 --> 03:50.700 Let's click on this tag and then click on this add tag. 03:50.820 --> 03:53.260 And let's create a new tag for our show. 03:53.260 --> 03:55.100 So let's click on this plus icon. 03:55.300 --> 03:58.930 And we're going to no sorry we're not gonna name it to something like. 03:58.930 --> 03:59.290 So. 03:59.370 --> 04:04.010 Instead, we're gonna call it trap because we're gonna have multiple traps, so that's why. 04:04.250 --> 04:10.570 So let's call this one trap, and let's click on the save button and then select your game object. 04:10.570 --> 04:15.530 Then go over to Inspector and Assign with the tag which you recently created. 04:15.530 --> 04:18.370 So I assigned this game object as a trap. 04:18.370 --> 04:20.770 As you can notice in Inspector. 04:20.770 --> 04:24.450 So I assigned this game object as a trap tag. 04:24.490 --> 04:26.130 And now we can just go ahead. 04:26.130 --> 04:30.210 We can and then we can and we can just make the animation. 04:30.210 --> 04:31.730 So let's make the animation. 04:31.730 --> 04:38.090 So to make the animation we will move over to our project app assets and then sprites folder. 04:38.090 --> 04:40.970 And we will head over to that folder. 04:40.970 --> 04:43.410 And then we will head over to Source folder. 04:43.970 --> 04:46.330 There we can see we have the sprite sheet. 04:46.330 --> 04:52.050 So just click in this arrow to see the individual and select all of them by holding down shift. 04:52.050 --> 04:58.550 And then and then drag it over to this game object on top of this object in the hierarchy. 04:58.710 --> 05:01.310 In order to make the animation right away. 05:01.630 --> 05:03.750 So just wait a little moment. 05:03.750 --> 05:05.310 It's lagging a little bit. 05:05.510 --> 05:09.070 So we need to place the animation where we want to place it. 05:09.070 --> 05:14.750 So for that I'm going to just click on this double arrow in the top left side we can see and let's click 05:14.750 --> 05:16.630 on this assets in assets. 05:16.630 --> 05:20.390 We already created a animation folder as you can notice. 05:20.390 --> 05:23.150 So we're going to open that up by double clicking on it. 05:23.150 --> 05:27.590 And let's uh let's create a sub folder for our traps. 05:27.590 --> 05:31.990 So let's right click and then new and folder. 05:31.990 --> 05:35.310 And we're going to call this folder to something like traps folder. 05:35.630 --> 05:41.830 So let's call it traps underscore underscore animation animation. 05:41.830 --> 05:45.710 And let's open up this sub folder by double clicking on it. 05:46.070 --> 05:47.670 So just bit wait. 05:47.790 --> 05:49.190 So I really apologize. 05:49.190 --> 05:50.990 It's just lagging a little bit. 05:50.990 --> 05:53.670 So let's open that up by double clicking on it. 05:53.670 --> 05:55.770 And we have to name the animation. 05:55.770 --> 05:58.770 So this will be show, uh, and it's gonna spin. 05:58.770 --> 06:01.130 So I'm going to call it simply something like so. 06:01.130 --> 06:02.290 So let's call it so. 06:02.330 --> 06:05.290 And after doing that let's click on the save button. 06:05.290 --> 06:10.650 And now if we click on this save button and then select our show GameObject in the hierarchy. 06:10.690 --> 06:12.730 Then move over to the animation tab. 06:12.770 --> 06:17.970 You will notice that this GameObject just gonna spin around itself. 06:17.970 --> 06:21.850 So just wait a moment and you will be able to notice that. 06:22.290 --> 06:27.290 So just wait a moment and once it's done, we can just go ahead and check that out. 06:27.330 --> 06:31.130 As you can notice we just created the animation. 06:31.130 --> 06:33.890 So I'm going to select my shock GameObject in the hierarchy. 06:33.890 --> 06:36.290 And let's move over to this animation tab. 06:36.290 --> 06:42.370 In order to check the animation, let's click on this play button in animation tab. 06:42.370 --> 06:50.130 And indeed we can notice that this shock GameObject just rotating itself in the z axis as you can notice. 06:50.130 --> 06:58.230 So we just created and also let's create a script in order to move this game object between 2 or 3 points. 06:58.230 --> 07:02.630 Even more than that, points even more than 5 or 10 points. 07:02.630 --> 07:09.470 It's basically up to you how many points you just want to move your traps or this game object. 07:09.470 --> 07:11.550 For that, we need to create a script. 07:11.550 --> 07:14.710 To do that, we will head over to our project tab. 07:15.030 --> 07:18.750 Then we will head over to assets folder and then Script Folder. 07:18.790 --> 07:22.750 Let's right click there, then create, then Monobehaviour script. 07:22.790 --> 07:25.270 And you can name that script to something like Shaw. 07:25.310 --> 07:28.070 It's up to you, whatever you want to call it. 07:28.070 --> 07:33.870 I already created a script called so and I have it right over here as you can notice. 07:33.870 --> 07:36.750 So I'm going to select my game object in the hierarchy. 07:36.910 --> 07:42.350 And let's select this script and drag it over to this add component section and Inspector. 07:42.350 --> 07:45.230 Or you can simply click on this add component. 07:45.230 --> 07:48.270 And you can find the script by typing the name of the script. 07:48.270 --> 07:51.430 And then click on it in order to attach that. 07:51.670 --> 07:56.130 So we want to move Uh, our shock ammo check between two points. 07:56.130 --> 07:58.010 So let's create those two points. 07:58.010 --> 08:00.690 To do that, I'm going to move over to my hierarchy. 08:00.690 --> 08:01.770 Let's right click. 08:01.770 --> 08:04.570 Let's firstly create an empty parent game object. 08:04.570 --> 08:10.810 And inside that parent game object we're going to create two child game object to just keep our hierarchy 08:10.850 --> 08:12.010 a little bit clean. 08:12.250 --> 08:15.210 So we're going to create an empty parent game object first. 08:15.210 --> 08:18.330 And let's call this GameObject to something like points. 08:18.330 --> 08:22.930 So let's call it points and then go over to Inspector then transform. 08:22.930 --> 08:25.330 Then right click transform and then reset. 08:25.570 --> 08:31.130 And if you want to choose an uh gizmos or icon then go over to Inspector. 08:31.130 --> 08:33.170 Click here in this box. 08:33.170 --> 08:36.130 And then we're going to choose this yellow or anything like that. 08:36.490 --> 08:37.810 Let's click on this. 08:38.770 --> 08:41.290 I guess we are able to see. 08:43.570 --> 08:44.530 I don't know. 08:46.970 --> 08:47.490 Okay. 08:47.530 --> 08:48.370 That's fine. 08:48.370 --> 08:49.530 We can just okay. 08:49.570 --> 08:51.050 We have it over here. 08:51.250 --> 08:54.070 So now as you can see we created this point. 08:54.230 --> 08:55.470 Points game object. 08:55.510 --> 08:58.750 Now we're gonna create two tile game object or two points. 08:58.750 --> 09:04.030 In order to move this swap between those two points or more than two points. 09:04.230 --> 09:06.470 So let's right click on this point game object. 09:06.470 --> 09:08.590 Let's create an empty game object. 09:08.590 --> 09:12.790 And we can call this one first point or let's simply call it one. 09:12.790 --> 09:15.470 And now we're going to select the move tool in the scene view. 09:15.470 --> 09:17.470 And let's select that game object. 09:17.470 --> 09:20.150 And let's move it somewhere around here. 09:20.390 --> 09:24.190 And if you want to choose any gizmos for it then go over to Inspector. 09:24.190 --> 09:24.990 Click here. 09:24.990 --> 09:26.990 And we're gonna choose this yellow one. 09:26.990 --> 09:34.390 As you can notice right over here we have and let's duplicate this one in order to create the second 09:34.390 --> 09:34.950 point. 09:34.990 --> 09:40.510 To do that I'm going to select my one game object underneath my points GameObject in the hierarchy. 09:40.910 --> 09:44.390 Let's select that and we're going to press down Ctrl D to duplicate. 09:44.390 --> 09:47.270 And let's move it down somewhere over here. 09:47.270 --> 09:53.700 So between these two points we just want to move our at this raw game object and let's call the duplicate 09:53.700 --> 09:57.700 point, uh, point to something like two, uh, like that. 09:57.700 --> 10:02.020 So that's why we created an empty parent game object, as you can see. 10:02.060 --> 10:07.420 And inside that parent game object, we just created these two child game object or these two points. 10:07.420 --> 10:09.740 And we can just click over here to collapse. 10:09.780 --> 10:13.660 As you can see now our hierarchy seems a lot more clean. 10:13.660 --> 10:17.420 So that's why we just created an empty parent game object first. 10:17.420 --> 10:21.740 And inside that parent game object we just created two child game object. 10:21.740 --> 10:25.220 Or you can simply say these two points or position. 10:25.580 --> 10:31.460 And I'm going to select Mysore and let's move it somewhere over here like that. 10:31.460 --> 10:35.060 And we can just go ahead and we can open up our script. 10:35.060 --> 10:37.060 So we're going to open up our source script. 10:37.180 --> 10:40.500 Uh, so let's select our source GameObject in the hierarchy. 10:40.540 --> 10:45.140 Let's go over to Inspector and let's open up the source script by double clicking on it. 10:45.300 --> 10:49.420 And what we need, we basically need a reference both of those point. 10:49.420 --> 10:52.720 So we can just move between those two points. 10:52.840 --> 10:58.080 So what we will do, we will go to top of our class, uh, class. 10:58.080 --> 11:02.880 And over here we're going to make a serialized field and that will be transformed. 11:03.000 --> 11:04.960 So let's make it over here. 11:05.280 --> 11:07.560 So let's make a serialized field. 11:08.880 --> 11:09.480 Sorry. 11:10.080 --> 11:11.920 Serialized field. 11:13.600 --> 11:14.600 Serialized field. 11:14.880 --> 11:15.600 Sorry. 11:15.640 --> 11:17.840 I really apologize for that. 11:18.640 --> 11:19.040 Okay. 11:19.080 --> 11:20.240 Serialized field. 11:20.440 --> 11:22.400 And this will be private. 11:22.440 --> 11:24.560 We're going to mark private instead. 11:24.560 --> 11:26.200 Even we made it private. 11:26.240 --> 11:32.360 We are gonna able to notice, since we just mark mark it as a serialized field. 11:32.400 --> 11:35.160 As you can notice, and we need a reference. 11:35.480 --> 11:36.840 Both of these points. 11:36.840 --> 11:40.680 We need both of these points, this first point and the second point. 11:40.920 --> 11:42.800 Or you can simply say position. 11:42.800 --> 11:48.240 So we need to type transform because transform we don't know it's responsible for position. 11:48.240 --> 11:49.720 So we're going to type transform. 11:49.720 --> 11:54.780 And we can call points, but we have more than one point, as you can notice. 11:55.060 --> 11:59.380 Uh, as you can notice, we have this first point and the second point. 11:59.380 --> 12:01.940 So we basically need to create an array. 12:02.100 --> 12:06.580 So basically right after this transform you basically need to make this brackets. 12:06.580 --> 12:08.100 And now this is an array. 12:08.300 --> 12:12.060 An array basically you can uh you can put multiple things. 12:12.060 --> 12:16.020 It can be anything like game object numbers even position. 12:16.020 --> 12:20.380 So that's why we just made this array basically square brackets. 12:20.380 --> 12:23.300 And we have to name the array what we want to name it. 12:23.300 --> 12:25.580 So we're going to call it something like points. 12:25.580 --> 12:27.900 And let's close that up with semicolon. 12:27.900 --> 12:33.340 And now we just created our points array basically a variable. 12:33.340 --> 12:35.220 And we're going to put our first point. 12:35.220 --> 12:39.820 And the second point inside this array that we created which is our points. 12:39.820 --> 12:42.980 So now I'm going to press down Ctrl s to save my script. 12:43.020 --> 12:47.540 And now let's move over to unity in order to save our script. 12:47.540 --> 12:49.520 And we need to assign those points. 12:49.520 --> 12:51.560 So we just created an array. 12:51.560 --> 12:55.560 And we do know that array is basically a parameter type. 12:55.560 --> 12:58.040 But it can hold up multiple values. 12:58.040 --> 12:59.320 It can be numbers. 12:59.320 --> 13:00.560 It can be names. 13:00.560 --> 13:01.680 It can be position. 13:01.680 --> 13:04.240 It can be, uh, anything like that. 13:04.240 --> 13:08.440 So you need to make square brackets right after your transform you making. 13:08.440 --> 13:10.240 So make sure you just do that. 13:10.480 --> 13:13.280 And that's basically reference our array. 13:13.600 --> 13:15.880 And we need to take one by one point. 13:15.880 --> 13:18.720 And we can simply just drag it into this array. 13:18.960 --> 13:25.280 And in the start of the end basically once our source script just gonna compile completely, uh, our 13:25.320 --> 13:26.680 array is just gonna be empty. 13:26.800 --> 13:32.320 So we need to put, uh, both of these point the first point and the second point into that array, 13:32.760 --> 13:34.160 and you will see that. 13:34.160 --> 13:40.600 So just wait a moment and once our compilation is done, we can just go ahead and we can just assign 13:40.600 --> 13:46.360 those points, or we can just store the first point and the second point into that points array that 13:46.360 --> 13:49.740 we created inside our C script. 13:49.740 --> 13:55.860 So just wait a moment to compile our script, and once it's done, we can just go ahead and we can assign 13:55.860 --> 14:02.820 those, uh, assign those, or we can simply drag one by one, uh, into that points array. 14:03.220 --> 14:09.180 So as soon as our, uh, script compiles, as you can notice points and it says zero. 14:09.180 --> 14:13.460 So what we can do, we can just move over to hierarchy than points game object. 14:13.460 --> 14:17.980 And we can select the first point and drag it over to this points uh array. 14:17.980 --> 14:22.580 And then we're going to select the second one and let's drag it over to this points array. 14:22.740 --> 14:25.540 Now we can notice we have the both of these points. 14:25.740 --> 14:33.020 Uh so this first point basically the top one we can see it's assigned with a zero index as you can see. 14:33.060 --> 14:37.540 And the bottom position or the second position we can see index is one. 14:37.540 --> 14:40.900 So both of these position just get assigned with an index. 14:40.900 --> 14:46.340 So the top position or the first uh first position index or the point uh point index. 14:46.340 --> 14:49.880 We can notice it's zero and the second one is one. 14:49.880 --> 14:52.960 So let's suppose we want to move to the first point. 14:52.960 --> 14:56.320 So what we need to do we basically need to pass our zero. 14:56.320 --> 15:01.640 So in order to move our show game object we basically need to open up our script. 15:01.640 --> 15:04.800 So let's double click on it in order to open that up. 15:04.800 --> 15:07.040 And we will go to top of our class. 15:07.040 --> 15:12.320 And we're going to declare a private variable to just keep track of which point we are in. 15:12.520 --> 15:17.160 And we do know that if the index is zero, it's going to be the first point. 15:17.160 --> 15:21.840 And if the index is one basically means the second point or the bottom point. 15:21.840 --> 15:26.120 So we're going to make a variable to just keep track of which point we are in. 15:26.120 --> 15:27.960 So we're going to make a private. 15:27.960 --> 15:30.400 And that will be in like 0123. 15:30.400 --> 15:33.880 And we can call this one index point point index. 15:33.920 --> 15:38.440 Let's call it simply point index point index. 15:38.440 --> 15:40.760 And let's close that up with semicolon. 15:40.760 --> 15:44.480 And now what I'm going to do I'm going to move over to my start function. 15:44.480 --> 15:45.640 So this is a start function. 15:45.640 --> 15:48.510 Get call in the start of the game and the start of the game. 15:48.510 --> 15:50.830 I'm gonna set this point index to zero. 15:50.830 --> 15:55.750 So I'm going to set point index sorry point index equal to zero. 15:56.110 --> 15:58.510 And let's close that up with semicolon. 15:58.510 --> 16:02.030 And now what we're going to do we're going to move over to this update function. 16:02.030 --> 16:05.590 And we do know that this update function runs every single frame. 16:05.590 --> 16:10.470 So every single frame we need to move over this short game object between these two points. 16:10.470 --> 16:12.750 So we want to move to the first point. 16:12.750 --> 16:15.190 So as index we're going to pass zero. 16:15.190 --> 16:19.470 So in order to move that what we need to do we need to use a function. 16:19.470 --> 16:23.510 And it's called it's called vector2 dot move towards. 16:23.510 --> 16:26.470 But before we do we need to set the current position. 16:26.470 --> 16:30.710 So we will go to transform dot position and transform dot position. 16:30.710 --> 16:33.990 Right over here basically means the current position of that. 16:33.990 --> 16:40.390 So game object basically this game object current position as you can notice in the inspector. 16:40.670 --> 16:45.190 And so what we're gonna do we're gonna set the current position equal to vector two. 16:45.690 --> 16:49.050 a vector2 dot move towards function vector two dot. 16:49.690 --> 16:55.490 Sorry, you need to use this function and this vector to dot move towards function as a first argument. 16:55.490 --> 17:00.330 It's going to take the take the current position where you are in. 17:00.330 --> 17:05.250 So we're going to pass our transform dot position which basically means our current position. 17:05.250 --> 17:09.770 And the second it's going to take the target position or via equipment to go. 17:09.770 --> 17:11.930 So we're going to pass our points array. 17:11.930 --> 17:14.690 So we basically need to type our points array. 17:14.690 --> 17:18.170 Or basically we have to type the point points array. 17:18.210 --> 17:20.650 Or basically we need to pass our array. 17:20.770 --> 17:22.730 And then we need to make these brackets. 17:22.730 --> 17:27.810 And inside this bracket you have to put the index a put. 17:27.930 --> 17:31.970 You can put the index that you just want to move over to that point. 17:31.970 --> 17:35.330 So I'm going to pass my point index I just created. 17:35.330 --> 17:40.090 And make sure right after this square brackets you need to type the dot position. 17:40.090 --> 17:45.270 Because this this basically this array is a Transform array. 17:45.270 --> 17:47.710 Or you can simply say position array. 17:47.830 --> 17:53.350 And the third argument is going to take the speed with how much speed you just want to move over to 17:53.390 --> 17:54.150 that point. 17:54.150 --> 17:57.110 So we're going to declare a variable for our speed. 17:57.110 --> 18:02.830 So let's go to the top of our class and let's make another serialized field and private. 18:03.030 --> 18:04.550 And this will be float. 18:04.550 --> 18:07.390 And we can call this one something like move speed. 18:07.390 --> 18:09.150 So let's call it move speed. 18:09.190 --> 18:14.150 And let's uh by default I'm going to set something like to f something like that. 18:14.150 --> 18:20.030 And third argument we're going to pass our move speed and make sure you multiply this with time dot 18:20.070 --> 18:22.510 delta time to make frame rate independence. 18:22.510 --> 18:24.910 So I'm going to pass our time delta time. 18:24.910 --> 18:27.150 And let's close that up with semicolon. 18:27.150 --> 18:30.310 So what we simply doing inside this update function. 18:30.310 --> 18:33.950 So transform.position basically means the current position of that. 18:33.990 --> 18:38.550 So game object and we're setting equal to Vector2 dot move towards function. 18:38.550 --> 18:40.830 And this vector2 dot move towards function. 18:40.830 --> 18:46.330 Basically as a first argument it's going to take the current position where you are currently right 18:46.330 --> 18:46.770 now. 18:46.770 --> 18:53.010 So we just pass Transform.position, which basically referencing the position we are currently in or 18:53.010 --> 18:56.210 current position, current position of that GameObject. 18:56.330 --> 19:01.850 And the second thing, it's going to take the target position or where you want to move your game object. 19:01.850 --> 19:03.730 So we pass our points. 19:03.730 --> 19:07.930 And inside this square brackets we basically need to pass the index. 19:07.930 --> 19:10.570 And we pass point point index. 19:10.570 --> 19:15.850 And as you can notice in the start of the game we just set our point index to zero. 19:15.850 --> 19:18.610 So this one right over here it's going to be zero. 19:18.610 --> 19:23.290 And we do know that zero basically means the top position or the first point. 19:23.290 --> 19:26.770 So this game object is just going to move over to that point. 19:26.770 --> 19:32.890 So if I move over to my script one more time so just wait you will notice. 19:33.090 --> 19:38.410 So we're gonna move towards to the first position as soon as we're gonna start our game. 19:38.730 --> 19:41.170 As you can notice right over here. 19:41.170 --> 19:44.110 So this point index is zero and zero. 19:44.110 --> 19:46.390 So we're just going over to that position. 19:46.630 --> 19:51.510 Uh, right after, uh, we just accessing the, uh, position of that array. 19:51.550 --> 19:52.790 As you can notice. 19:52.790 --> 19:58.430 And the third argument is just taking the speed with, uh, how much speed we just moving over to that 19:58.430 --> 19:58.950 point. 19:58.950 --> 20:03.070 And now what we're going to do, we're going to press down Ctrl s to save our script. 20:03.070 --> 20:05.110 And now let's move over to unity. 20:05.110 --> 20:11.390 And you will see, as soon as we're gonna start our game, we will able to notice our game object, 20:11.390 --> 20:17.750 or this trap is going to move over to the first point or the top position because the top position index 20:17.750 --> 20:18.470 is zero. 20:18.470 --> 20:19.390 So that's why. 20:19.630 --> 20:25.830 So just wait a moment and you will see, uh, you will see that, uh, we basically just going to move 20:25.830 --> 20:31.830 over to the first point as soon as we're gonna start our game, because the first point index is zero. 20:31.830 --> 20:37.470 And we can notice underneath our show script and the first point index, we can notice it's zero. 20:37.470 --> 20:39.830 And the second point index is one. 20:40.070 --> 20:43.170 So let's suppose you just want to move to the second point. 20:43.170 --> 20:47.650 So as a as a index you need to pass this one. 20:47.650 --> 20:53.690 So it's you you're just going to move over to that point or the bottom position or simply the second 20:53.690 --> 20:54.450 position. 20:54.450 --> 21:00.290 Now our script gets compiled and I'm going to drag my stroke game object a little bit down somewhere 21:00.290 --> 21:01.130 over here. 21:01.370 --> 21:06.890 And if I just go ahead and then click on this play button, you will see as soon as we're gonna, uh, 21:07.250 --> 21:13.610 start our game, these are just going to move over to the top position or the first position because 21:13.650 --> 21:17.450 as in point index, in the start of the game, we just set it to zero. 21:17.450 --> 21:19.930 And zero basically means the first point. 21:19.930 --> 21:22.090 And you're gonna notice that. 21:22.250 --> 21:29.730 And indeed we can notice that it's, uh, going to the first position and it's just sticking right over 21:29.730 --> 21:30.290 here. 21:30.290 --> 21:36.810 So we also need to uh, basically we also need to move over to this second position or this bottom position. 21:36.810 --> 21:41.680 So basically what we have to do, we need to increase our point index by one. 21:41.680 --> 21:46.000 And we do know that if we put a one inside that array point. 21:46.040 --> 21:48.440 Index array point index one. 21:48.440 --> 21:51.920 So it's going to move over to second position or the bottom position. 21:51.920 --> 21:57.320 Because the bottom position we can notice underneath our show script is index is one. 21:57.320 --> 21:58.840 So let's get out of play mode. 21:58.840 --> 22:04.520 So what we're gonna do before we just move over to the first position, we basically want to check the 22:04.520 --> 22:07.360 position between our first point and this. 22:07.520 --> 22:14.720 So game object if the position between our show and the first point or this point with this point is 22:14.720 --> 22:19.080 too much close, then we're just going to increase our point index by one. 22:19.360 --> 22:21.280 And we do know if we increase. 22:21.680 --> 22:25.600 So it's going to move over to the bottom position or the second position. 22:25.600 --> 22:27.040 So let's go over to script. 22:27.040 --> 22:28.680 And we're going to do it over here. 22:28.680 --> 22:31.440 So before we move position we just want to check. 22:31.800 --> 22:35.680 So let's make if condition make first bracket and some curly brackets. 22:35.680 --> 22:39.280 And what we want to check over here we basically want to check. 22:39.280 --> 22:42.700 So we need to use this vector to dot distance function. 22:43.340 --> 22:49.820 And this function it's going to take two position and it's going to take two position. 22:49.820 --> 22:51.980 And it will compare between them. 22:51.980 --> 22:54.700 So we want to check the position with our saw. 22:54.700 --> 22:57.340 So we're going to pass our transform dot position. 22:57.380 --> 23:00.580 It's basically means current position of that object. 23:00.580 --> 23:06.180 And the second thing it's going to take the basically as a second argument it's going to take another 23:06.180 --> 23:08.780 position that we want to compare with. 23:08.780 --> 23:10.740 So we're going to pass our points array. 23:10.940 --> 23:14.860 So we need to pass points array a points array. 23:15.060 --> 23:17.260 And we need to make this square brackets. 23:17.260 --> 23:21.460 And inside this square brackets we basically have to pass our index. 23:21.460 --> 23:24.580 So we're going to pass our point index and point index. 23:24.580 --> 23:26.700 In the start of the game we set zero. 23:26.700 --> 23:28.260 So it's our game object. 23:28.260 --> 23:34.900 Just gonna check the position between our this row and this first position and make sure you access 23:34.900 --> 23:35.740 the position. 23:35.740 --> 23:42.480 So right typing square brackets you need to type this dot position because we need to access the position. 23:42.480 --> 23:48.840 And now if the position between them, if it's lesser than some small number, some smaller number, 23:48.840 --> 23:49.880 we're going to check with. 23:49.920 --> 23:54.040 So we're going to put zero point 1FA pretty smaller number something like that. 23:54.040 --> 23:57.400 So if that is the case basically means our game object. 23:57.400 --> 24:03.320 So we using this Vector2 dot distance function and this Vector2 dot distance function, it's going to 24:03.320 --> 24:06.360 take two position and it will compare between them. 24:06.360 --> 24:12.320 So we just pass as a first argument current position which is transform.position basically means current 24:12.320 --> 24:13.240 position of that. 24:13.280 --> 24:14.280 So game object. 24:14.280 --> 24:21.440 And the second thing we just pass our point index or the top position or where we just moving. 24:21.600 --> 24:25.800 And in this start of the game we do know this point index that's going to be zero. 24:25.800 --> 24:31.680 So in the start of the game this if condition is just going to check the between our this game object 24:31.680 --> 24:33.040 and this first point. 24:33.040 --> 24:38.940 So if it's lesser than some smaller number as you can see we're checking then what we need to do basically 24:38.940 --> 24:41.340 means we just reaches right over here. 24:41.340 --> 24:45.060 So we basically need to increase our point index by one. 24:45.060 --> 24:50.300 And if we increase point index by one then it's going to move over to this point index. 24:50.460 --> 24:50.820 Sorry. 24:50.860 --> 24:54.140 It's going to move over to bottom position or second position. 24:54.140 --> 24:58.340 You can simply say so now let's move over to unit is script. 24:58.340 --> 25:01.900 And now what we have to do we reaches our first point. 25:01.900 --> 25:08.220 You can simply say the the distance between our show and the first point is too much close now. 25:08.220 --> 25:11.980 And now what we need to do we need to increase our point index. 25:11.980 --> 25:15.700 So what we will do, we will use this point index plus plus. 25:15.740 --> 25:18.380 It basically means that we just adding one. 25:18.380 --> 25:20.540 So in this start of the game we set zero. 25:20.540 --> 25:23.340 So plus plus basically means we adding one. 25:23.340 --> 25:24.580 So zero plus one. 25:24.620 --> 25:25.740 It's going to be one. 25:26.180 --> 25:28.620 So this point index it's becoming one. 25:28.620 --> 25:31.900 So this over here right over here it's going to be one. 25:31.900 --> 25:37.620 So so our now the game object just going to move over to our second point. 25:37.680 --> 25:40.360 because this point index is just going to be one. 25:40.400 --> 25:47.360 As soon as our game object reaches top point or the first position, then we increasing our point index 25:47.640 --> 25:48.400 by one. 25:48.400 --> 25:51.240 So the point index right over here becomes one. 25:51.280 --> 25:55.520 Means our game object just going to move over to our bottom position. 25:55.520 --> 25:58.360 Or you can simply say the second position. 25:58.360 --> 26:01.280 And now we're going to press down Ctrl S to save our script. 26:01.280 --> 26:02.920 And let's move over to unity. 26:03.120 --> 26:09.480 So as soon as our game object just just going to reach our top position, it's going to move over to 26:09.520 --> 26:10.440 second position. 26:10.440 --> 26:16.120 Because the we checking the distance between our shore and the first point, if it's lesser than with 26:16.120 --> 26:20.520 some smaller number, then we just increasing our point index by one. 26:20.520 --> 26:26.000 And we do know if we increase by one that means point index becoming one and one. 26:26.000 --> 26:28.240 We do know that is the second position. 26:28.240 --> 26:31.040 Or you can simply say this bottom position. 26:31.040 --> 26:33.680 So just wait a little moment and it's done now. 26:33.680 --> 26:36.040 So I'm going to move it somewhere over here. 26:36.040 --> 26:37.860 And let's click on this play button. 26:37.860 --> 26:43.460 And you will see as soon as this game object and the first point, uh, first point position, if the 26:43.460 --> 26:47.220 distance between is too much close, then we increasing. 26:47.620 --> 26:52.780 Then we increasing our point index means it's gonna move over to the second position. 26:52.780 --> 26:55.620 Or you can simply say to the bottom position. 26:55.620 --> 26:57.140 So just wait a moment. 26:57.140 --> 27:00.820 And indeed we can see it just reaching the second position. 27:00.820 --> 27:07.380 And now it's stuck at second position or this bottom position because we just keep increasing our point 27:07.420 --> 27:08.060 index. 27:08.060 --> 27:09.780 So we're gonna get out of play mode. 27:09.780 --> 27:15.620 So now what we're gonna do if this short game object is, uh, something like over here with the second 27:15.620 --> 27:21.140 position, uh, or the bottom position, you can simply say if the distance between is now too much 27:21.140 --> 27:23.020 close with the second position. 27:23.020 --> 27:26.620 Then again, we're gonna set back our point index to zero. 27:26.620 --> 27:33.060 So this, uh, so just gonna move over to top position if we set back, uh, point index to zero, because 27:33.100 --> 27:35.300 zero basically means the top position. 27:35.300 --> 27:37.650 Or you can simply say the first position. 27:37.650 --> 27:41.050 So what we will do for that, we're going to move over to our script. 27:41.210 --> 27:42.970 And over here we're going to check. 27:42.970 --> 27:45.930 So let's go to top of our class and we will check. 27:45.930 --> 27:47.570 So we're going to use this if condition. 27:47.570 --> 27:50.170 Let's make first bracket and some curly brackets. 27:50.170 --> 27:52.170 And what we want to check over here. 27:52.170 --> 27:54.730 We basically want to check uh sorry. 27:55.610 --> 28:03.650 We basically want to check if our point index if it's equals equals to points uh points dot length. 28:04.010 --> 28:07.050 Points dot length basically means how many points we have. 28:07.290 --> 28:13.330 So point if the point index is equals equals to point dot length basically means how many points we 28:13.330 --> 28:13.730 have. 28:13.930 --> 28:17.370 So we have we can notice we have one and two. 28:17.530 --> 28:22.170 So this point index points dot length right over here it's going to be two. 28:22.370 --> 28:24.530 And if the point index is one. 28:24.930 --> 28:31.650 So as soon as it reaches our point basically means we just uh over here somewhere over here. 28:31.650 --> 28:36.310 So we're checking as you can see we're checking if our point index is equals. 28:36.350 --> 28:38.110 Equals to points dot length. 28:38.270 --> 28:41.590 Points dot length basically means how many points we have. 28:42.110 --> 28:45.070 Means our game object is right over here. 28:45.070 --> 28:46.390 So now what we need to do. 28:46.430 --> 28:49.190 We need to set back our point index to zero. 28:49.230 --> 28:50.510 Because we are increasing. 28:50.510 --> 28:55.310 And we are checking if the point index is equals equals to our points dot length. 28:55.350 --> 29:00.630 So if that is the case then we're going to set back this point index to zero once again. 29:00.630 --> 29:07.310 And we do know if we set back to zero it's going to move over to our top position or the first position. 29:07.310 --> 29:10.110 So we're going to set our point index back to. 29:10.150 --> 29:13.190 So let's set our point index equal to zero. 29:13.190 --> 29:15.230 And let's close that up with semicolon. 29:15.230 --> 29:17.950 And we're going to press down Ctrl s to save our script. 29:17.950 --> 29:19.830 And now let's move over to unity. 29:19.830 --> 29:25.430 So as soon as this game object just going to check with second position or the bottom position. 29:25.430 --> 29:28.470 And we do know once it's just going to reach bottom position. 29:28.470 --> 29:30.830 So the index point index is going to be one. 29:30.830 --> 29:34.210 And we're checking if the point index is equals Equals. 29:34.210 --> 29:34.370 To. 29:34.410 --> 29:34.530 To. 29:34.570 --> 29:34.730 Oh. 29:34.770 --> 29:35.410 Or that. 29:35.450 --> 29:36.890 How many points we have. 29:36.930 --> 29:40.290 Then we again setting back our point index to zero. 29:40.290 --> 29:44.330 And we do know that the point index zero basically means the top position. 29:44.330 --> 29:47.970 And point index one basically means the bottom position. 29:48.090 --> 29:54.250 So we will able to notice that this game object just going to move between these two points, once it's 29:54.250 --> 29:59.930 going to reach the bottom position, then it's again going to move over to top position because we changing 29:59.930 --> 30:01.130 the point index. 30:01.290 --> 30:05.170 So let's click on this play button in the top in order to play our game. 30:05.170 --> 30:08.930 And we're gonna take a look on that on this. 30:08.930 --> 30:15.650 So as soon as this point sorry this game object just going to check with the second position or the 30:15.650 --> 30:19.490 bottom one is going to move over to the first point once again. 30:19.770 --> 30:23.770 And we can notice that it's moving to the first point and second point. 30:23.770 --> 30:30.810 And as soon as it's reaching or sorry reaching to the second point, we can see it just moving over 30:30.810 --> 30:31.970 to the first point. 30:31.970 --> 30:33.790 But we getting an array? 30:34.150 --> 30:38.790 Sorry, we're getting an error in our console tab that says. 30:38.830 --> 30:42.430 Index was outside the bounds of the array. 30:42.590 --> 30:44.950 So we basically need to get out of play mode. 30:44.950 --> 30:47.310 And we need to move over to our script. 30:47.310 --> 30:53.150 And we need to put this line of code right over here underneath, uh, underneath everything. 30:53.270 --> 30:59.350 Uh, so we can just move, we can select like this and we can hold down alt or alt key on our keyboard, 30:59.350 --> 31:05.310 and we can use our up or down arrow key in order to move this line of code, as you can notice. 31:05.430 --> 31:07.750 So I'm gonna move it somewhere over here. 31:07.750 --> 31:09.110 And now that's fine. 31:09.110 --> 31:14.550 And make sure you press down Ctrl s on your keyboard in order to save your script one more time. 31:14.870 --> 31:16.070 And it's gonna save. 31:16.310 --> 31:18.270 So I hope you get the idea. 31:18.310 --> 31:23.150 Now I'm gonna press down one more time to control S, and let's move over to unity. 31:23.150 --> 31:24.870 So it's gonna be fine by now. 31:25.190 --> 31:28.790 We're not gonna see any error in our console tab. 31:29.150 --> 31:35.170 I hope you get the idea that how you can just move a game object between two points and you can create 31:35.170 --> 31:36.850 as many points you want. 31:36.890 --> 31:39.610 So you can just duplicate this second point. 31:39.610 --> 31:46.370 And you you need to make sure that you also, uh, also select the third point and then drag it over 31:46.370 --> 31:53.330 to this points array, or else you're gonna get some error or you not gonna move over to the third position. 31:53.330 --> 31:54.250 So that's why. 31:54.290 --> 31:55.770 And I'm gonna show you that. 31:56.210 --> 31:58.730 So let it first compile it. 31:59.570 --> 32:04.930 And let's click on this play button in the top in the in order to play our game. 32:05.170 --> 32:06.970 And let's take a look on this. 32:09.690 --> 32:11.850 So just wait wait a moment. 32:11.850 --> 32:17.370 And by now we should not see any error messages. 32:17.370 --> 32:19.930 Just going to pop up underneath our console tab. 32:20.250 --> 32:21.930 So I'm going to clear it first. 32:22.130 --> 32:27.250 As you can notice in our console tab we not getting any error messages. 32:27.250 --> 32:30.490 Let's suppose we want to move this game object. 32:30.610 --> 32:31.870 Uh three points. 32:31.870 --> 32:33.910 Something over here as well. 32:33.910 --> 32:35.390 So we're gonna get out of play mode. 32:35.390 --> 32:35.870 For that. 32:35.870 --> 32:38.190 We need to create one more point. 32:38.350 --> 32:40.350 Or you can simply say position. 32:40.350 --> 32:42.990 So we will select the second or the first position. 32:42.990 --> 32:45.390 And let's press down Ctrl D to duplicate. 32:45.750 --> 32:46.590 Uh sorry. 32:46.630 --> 32:49.110 And we're going to move it somewhere over here. 32:49.110 --> 32:51.510 And let's call this point to something like three. 32:51.670 --> 32:52.910 So let's call it three. 32:53.070 --> 32:58.870 And now what we have to do we need to put this three point, uh, basically the third point into our 32:58.910 --> 33:01.870 array or else we're not gonna move at all. 33:01.870 --> 33:03.590 So to the third point. 33:03.590 --> 33:06.270 So I'm going to select my sock object in the hierarchy. 33:06.310 --> 33:08.790 Let's go over to our script in the Inspector. 33:09.030 --> 33:14.630 Uh, so we can see we only have the first point and the second point and we don't have the third point 33:14.830 --> 33:15.470 yet. 33:15.470 --> 33:19.590 So we will select the third point and let's drag it over to this point array. 33:19.630 --> 33:26.350 Now we can see uh, the third point index is now two, index is two, second point index is one. 33:26.350 --> 33:29.870 And the first point index is zero basically means this. 33:29.910 --> 33:35.780 Uh short game object just going to move around between these points, because we're just checking the 33:35.780 --> 33:37.860 distance between our points. 33:37.860 --> 33:42.940 And if that gets closer, then we just are increasing our point index. 33:42.940 --> 33:48.180 And once it reaches the final position, then again we're setting back point index to zero. 33:48.300 --> 33:52.660 So that's why this game object is just going to move over to first point one more time. 33:52.900 --> 33:57.580 So let's click on this play button in the top in order to take a look on this. 33:57.580 --> 34:03.660 And you can increase the speed as well by just going over to your your source script. 34:03.660 --> 34:06.660 And you can just play around with the move speed. 34:06.660 --> 34:10.140 So just wait a moment and we will able to notice that. 34:10.460 --> 34:16.900 So this game object just gonna move between these three points because we just increase and we will 34:16.940 --> 34:17.700 able to notice. 34:17.700 --> 34:19.540 So it's move it over here. 34:19.540 --> 34:23.620 Then here as you can notice indeed it's moving to the third point. 34:23.900 --> 34:28.460 And we basically need to move our show a little bit something over here. 34:28.660 --> 34:30.240 And we can notice that. 34:30.240 --> 34:32.000 So I'm going to get out of play mode. 34:32.000 --> 34:39.280 And what I'm going to do I'm going to move the third point somewhere over here to just to just make 34:39.320 --> 34:39.840 sure. 34:39.840 --> 34:44.520 So I'm going to select my third point and let's move it somewhere around here. 34:44.840 --> 34:48.640 And let's press down control S in order to save our project. 34:49.000 --> 34:50.760 And I'm going to move this here. 34:50.760 --> 34:55.320 So now let's click on this play button in the top in order to play our game. 34:55.480 --> 34:59.480 And we will be able to notice our game game object. 34:59.520 --> 35:02.960 Just going to move between these three points and one. 35:03.280 --> 35:09.160 Once it's gonna reach the final position or the third point, you can simply say then again we're setting 35:09.160 --> 35:12.760 back point index to zero basically means our show game object. 35:12.760 --> 35:17.000 Just gonna move over to our first point right away. 35:17.040 --> 35:23.480 As you can see, indeed the show game object just moving between these three points and you can create 35:23.480 --> 35:28.040 as many points you want and make sure you track those points into your array. 35:28.040 --> 35:33.060 So you're gonna have the position, and after that you can just move your game object. 35:33.060 --> 35:34.300 So I hope you get the idea. 35:34.300 --> 35:35.940 So I'm gonna get out of play mode. 35:35.940 --> 35:41.820 And also make sure you make this game object a prefab so you will have the copy of it. 35:41.820 --> 35:45.580 So I'm going to head over to my project tab then assets folder. 35:45.580 --> 35:49.340 So just wait a little bit assets folder and then prefabs folder. 35:49.540 --> 35:52.260 And let's select the GameObject in the hierarchy. 35:52.260 --> 35:57.660 And let's drag it inside this prefabs folder in order to turn it into a prefab. 35:57.660 --> 36:00.820 And now as you can notice, we just turn it into a prefab. 36:00.820 --> 36:07.220 Basically, it's turned out blue means we just made it prefab and we can just click on it at this point 36:07.220 --> 36:10.340 scheme object in order to collapse all of our points. 36:10.340 --> 36:15.940 So that's why we just created an empty parent game object first and into that game object, we just 36:15.940 --> 36:21.980 created those tile game object in order to make our hierarchy a little bit clean or the project, you 36:21.980 --> 36:27.740 can simply say, and we're going to press down one more time, Ctrl s on our keyboard in order to save 36:27.740 --> 36:28.660 our project.
