WEBVTT 00:00.020 --> 00:00.500 Hello guys. 00:00.500 --> 00:01.430 Welcome to the video. 00:01.430 --> 00:03.830 In this one I want to make another trap. 00:03.830 --> 00:08.000 Not so much of a trap, more like a movement mechanic, but still. 00:08.000 --> 00:09.650 It's very cool one I think. 00:10.310 --> 00:12.140 Let me switch off the trampoline. 00:12.890 --> 00:17.840 And let's go to asset Graphics traps arrow. 00:17.840 --> 00:24.470 And this is the, uh, thing that I want to make this arrow, you need to select both of them, make 00:24.470 --> 00:26.270 pixel per unit 16. 00:26.270 --> 00:30.410 And then let's take one of them and put it into the scene certain layer. 00:31.020 --> 00:34.770 Trump and let's rename it to Trap Arrow. 00:35.370 --> 00:40.500 It's not so much of a trap, more like a, you know, movement mechanic, but nevertheless it's very 00:40.500 --> 00:43.290 cool one and it's going to be extremely easy to make. 00:43.380 --> 00:46.500 First of all, let's set up animation for this one. 00:46.500 --> 00:49.530 And then I'm going to show you what we need to do to make it look even better. 00:49.530 --> 00:50.130 Okay. 00:50.430 --> 00:53.460 And let's go to animations traps. 00:53.460 --> 00:56.670 Over here I want to make folder for controllers. 00:59.160 --> 01:00.150 Nice. 01:00.210 --> 01:01.680 Now we're going to take these two. 01:01.680 --> 01:05.280 Drag them here and make another controller inside. 01:06.090 --> 01:08.850 Uh, trap arrow AC. 01:09.480 --> 01:11.490 Let's put it on the object. 01:13.400 --> 01:16.700 Also, we need a circle collider. 01:16.730 --> 01:18.950 We're going to make it as is. 01:18.950 --> 01:19.760 Trigger. 01:20.520 --> 01:24.270 And let's go to animator and make two animations. 01:25.450 --> 01:27.640 Gonna go to traps make. 01:30.960 --> 01:33.300 This was from my trial. 01:33.300 --> 01:37.230 Okay, so it's going to be arrow, uh, idle. 01:38.660 --> 01:39.680 Let's save it. 01:39.680 --> 01:40.100 Actually. 01:40.100 --> 01:40.670 Let's do. 01:40.700 --> 01:41.510 Trap. 01:41.510 --> 01:42.080 Arrow. 01:42.080 --> 01:42.830 Idol. 01:45.670 --> 01:46.060 All right. 01:46.060 --> 01:49.510 We're going to go to Graphics Traps arrow. 01:49.510 --> 01:51.250 And let's take this sprites. 01:51.700 --> 01:52.660 Put them here. 01:52.660 --> 01:54.610 Sample rate 20. 01:55.840 --> 01:58.690 Then we need one more trap. 01:58.690 --> 02:01.180 Arrow activated. 02:02.490 --> 02:07.050 You're going to take these and put them here with a sample rate 20. 02:07.260 --> 02:08.040 Nice. 02:08.070 --> 02:09.750 Now let's make a trigger. 02:11.860 --> 02:12.250 Uh. 02:12.250 --> 02:13.180 Activate. 02:14.450 --> 02:19.790 And we're going to transfer to this animation with a trigger over here. 02:19.790 --> 02:22.730 Exit I'm uncheck transition duration zero. 02:22.730 --> 02:23.900 That's good for now. 02:24.170 --> 02:30.890 Now let's go over here I think it should be a bit bigger because it's kind of small now. 02:30.890 --> 02:32.240 Barely can see it. 02:32.240 --> 02:35.600 So I'm going to make it as 1.5 over here. 02:35.690 --> 02:36.530 Very cool. 02:36.530 --> 02:37.760 This is a bit better. 02:38.180 --> 02:43.400 Now this object will push player and in the same way as a trampoline does. 02:43.400 --> 02:50.270 But also I'm going to rotate the object with the time like so, and because of that, player will have 02:50.270 --> 02:56.270 to catch the right moment and only jump on the arrow when it points to the direction where he needs 02:56.270 --> 02:56.780 to go. 02:56.780 --> 02:59.000 Okay, that's going to be the idea of it. 02:59.000 --> 03:05.150 And also I want to destroy the arrow once it is used, and then I want to create a new arrow after some 03:05.150 --> 03:07.190 amount of time, like with a cooldown. 03:07.700 --> 03:07.970 Yeah. 03:07.970 --> 03:10.460 So first let's make jumping mechanic for this one. 03:10.460 --> 03:13.820 And actually it's going to be very easy to do if we use inheritance. 03:13.820 --> 03:16.700 This is a good example of how we can use inheritance. 03:16.700 --> 03:18.920 And this is going to be just a brief explanation. 03:18.920 --> 03:23.360 I'm going to explain some things, but not too much because we're going to discuss inheritance more 03:23.360 --> 03:26.480 later on in the enemies section there. 03:26.480 --> 03:30.950 I'm going to pay lots of attention to the inheritance, but we also need to use it now. 03:30.950 --> 03:35.780 So I'm going to give you a quick example how it can be used and just, you know, just in case, I'm 03:35.780 --> 03:40.580 going to say that if you don't quite understand how inheritance work after this video, just wait for 03:40.580 --> 03:41.690 the enemies section. 03:41.690 --> 03:42.950 We're going to discuss it more. 03:42.950 --> 03:43.460 Okay. 03:43.460 --> 03:49.130 So we can go to scripts and we can make new C sharp script trap. 03:49.700 --> 03:50.270 Arrow. 03:53.110 --> 04:00.460 Trap arrow over here instead of Monobehaviour, we can type trap trampoline. 04:00.460 --> 04:07.690 And now this will mean that trap arrow inheriting properties and methods from a trap trampoline over 04:07.690 --> 04:08.290 here. 04:08.290 --> 04:09.370 This is what it does. 04:09.370 --> 04:13.180 Basically, it's like this object over here. 04:13.180 --> 04:16.540 Trap trampoline has a script of a trap trampoline. 04:16.540 --> 04:19.630 But Trap Arrow is inheriting. 04:19.630 --> 04:21.310 Let's put it on the object. 04:21.310 --> 04:23.290 We can see it has same variables. 04:23.290 --> 04:25.480 It is inheriting from a trap trampoline. 04:25.480 --> 04:29.350 And because of that, it sort of has two scripts in its possession. 04:29.350 --> 04:35.170 You know, this one has all the functionality that trap trampoline has over here. 04:36.650 --> 04:39.440 And because of that, we do need to do anything else here. 04:39.440 --> 04:44.000 We can just go to unity, give it push power of 25. 04:45.480 --> 04:47.970 And when I enter the trigger area. 04:51.200 --> 04:53.540 It's going to push me up just like that. 04:54.200 --> 04:58.130 Because it inherits the functionality from a trap trampoline. 04:58.160 --> 04:59.420 This is how it is. 05:01.710 --> 05:03.420 There is something that you should know. 05:03.450 --> 05:10.110 As of now, these methods are available to Trap arrow, but only because these methods are part of Monobehaviour 05:10.110 --> 05:11.850 like awake for example. 05:11.850 --> 05:18.300 Also on trigger, enter is triggered when something enters the trigger collider. 05:18.300 --> 05:25.320 But because these variables are private, as you can see and methods are private as well, we cannot 05:25.320 --> 05:26.880 adjust these variables. 05:26.880 --> 05:30.240 We cannot do anything with them on a trap arrow over here. 05:30.240 --> 05:36.180 As a example, if I type here awake, it's going to make a new method that has nothing in common with 05:36.180 --> 05:37.980 this awake over here. 05:37.980 --> 05:44.700 And also, even though we have anim and this trap arrow inherits from a trampoline, we cannot use anim 05:44.700 --> 05:45.660 here as well. 05:45.660 --> 05:47.190 We cannot use push force. 05:47.190 --> 05:54.750 If we want to use this variables, we need to make them as protected because private means these are 05:54.750 --> 05:56.730 available only to this class. 05:56.730 --> 05:58.680 But if we make them protected. 05:59.510 --> 06:06.710 Now it will be available to this class and to the class that inherits from, uh, trap trampoline. 06:06.710 --> 06:10.280 And now I can use any movie here, but still it is not public. 06:10.280 --> 06:12.470 So public is available to everyone. 06:12.470 --> 06:16.520 Private is available only to the class and protected is available to the class. 06:16.520 --> 06:19.460 And those classes that are inheriting from a main class. 06:19.460 --> 06:20.330 Simple as that. 06:20.330 --> 06:25.940 We do need to override any functionality from a trap trampoline for now, so I'm going to keep it as 06:25.940 --> 06:26.570 it is. 06:26.570 --> 06:32.180 Let's just leave it at that and let's go and make rotation for the arrow. 06:32.210 --> 06:34.010 It's going to be not that difficult to do. 06:34.040 --> 06:37.970 We want to have some sort of, uh, serialized field. 06:37.970 --> 06:44.720 Let's make a header, header, arrow or maybe additional additional info just like that. 06:44.720 --> 06:45.470 It's fine. 06:45.470 --> 06:48.680 I'm going to do private float rotation speed. 06:48.680 --> 06:53.120 Let's make it equals to 120 by default. 06:53.120 --> 06:57.620 And let's make serialized field private bool rotating. 06:57.620 --> 06:58.430 Right. 06:58.760 --> 07:02.270 Because we want to decide if we rotate arrow to the right or to the left. 07:03.020 --> 07:06.410 Um, then we need to open update method. 07:06.410 --> 07:12.260 And over here we're going to type transform rotate zero on the x zero on the y. 07:12.260 --> 07:14.960 We want to rotate only around z axis. 07:14.960 --> 07:19.940 If you go to unity uh select Rotation Tool and rotate the object. 07:22.270 --> 07:24.430 Over here, you'll see that Z changes. 07:24.430 --> 07:26.860 So we need to change the Z. 07:28.180 --> 07:29.080 Rotation. 07:30.070 --> 07:31.450 Let's go back here. 07:31.450 --> 07:33.910 I'm going to use a rotation speed. 07:33.910 --> 07:38.140 Multiply it by time dot delta time because I want it to be frame rate independent. 07:38.140 --> 07:38.860 Nice. 07:38.860 --> 07:42.250 Now let's go back and see this in the action. 07:44.430 --> 07:45.750 I'm going to go to play mode. 07:47.170 --> 07:48.760 We can see it's rotating. 07:49.490 --> 07:52.970 And I need to guess the right time to jump into the arrow. 07:54.390 --> 08:00.990 Because it always will push player to the up axis, and because object is rotating, this axis is always 08:00.990 --> 08:01.950 changing itself. 08:01.950 --> 08:05.070 For example, if I jump now, I'm going to be pushed back. 08:05.870 --> 08:06.800 Okay. 08:06.950 --> 08:07.970 Very cool. 08:10.140 --> 08:12.900 Let's go and make use of this boolean over here. 08:13.080 --> 08:16.650 I feel a bit lazy so I'm going to do this if rotating right. 08:18.610 --> 08:21.520 Then rotate with a minus speed. 08:21.880 --> 08:24.010 Else transform. 08:24.520 --> 08:26.560 Or actually, maybe we can do. 08:26.890 --> 08:27.220 Yeah. 08:27.220 --> 08:28.450 Let's be smart here. 08:28.450 --> 08:33.160 Private int direction equals to minus one by default. 08:33.610 --> 08:36.100 And then over here I'm going to do direction. 08:36.940 --> 08:39.010 Equals to rotating rate. 08:40.310 --> 08:43.310 Then use one, else use minus one. 08:43.310 --> 08:45.860 I hope I'm right because I might be wrong here. 08:46.720 --> 08:49.930 And then we're going to rotate with a rotation. 08:50.950 --> 08:54.970 Multiplied by direction, multiplied by direction. 08:54.970 --> 08:59.830 Let's put it into parentheses and multiply that with a time Delta time. 08:59.830 --> 09:00.400 Yeah. 09:01.240 --> 09:01.990 A bit cleaner. 09:01.990 --> 09:02.620 Very good. 09:02.620 --> 09:06.220 And also I want to destroy the arrow once it is activated. 09:06.220 --> 09:09.880 So I'm going to make Private Void destroy me. 09:09.880 --> 09:11.770 And it's going to just destroy the object. 09:11.980 --> 09:15.820 And let's do destroy GameObject just like that. 09:15.820 --> 09:17.500 Let's save this. 09:17.500 --> 09:19.300 Let's go back to unity. 09:21.650 --> 09:29.060 Over here on the animation of activated after the last frame over here I want to place. 09:30.060 --> 09:30.600 Trap. 09:30.600 --> 09:31.680 Arrow methods. 09:31.680 --> 09:32.700 Destroy me. 09:33.330 --> 09:33.990 Good. 09:33.990 --> 09:36.330 Now let's go and see the rotation. 09:37.460 --> 09:41.450 So now it says, okay, we need to do an opposite. 09:42.900 --> 09:43.230 Yeah. 09:43.230 --> 09:43.740 I'm sorry. 09:43.740 --> 09:46.080 Let's quickly change it before I forget. 09:46.590 --> 09:49.500 This should be minus one and one. 09:49.950 --> 09:50.550 Okay. 09:51.850 --> 09:52.390 Yeah. 09:52.390 --> 09:53.740 Uh, let's go now. 09:59.450 --> 10:01.220 And we can see it's rotating to the left. 10:01.220 --> 10:04.460 If I click the boolean, it is rotating to the right. 10:04.490 --> 10:09.140 Now I'm going to jump into an arrow and it was destroyed very well. 10:09.140 --> 10:11.210 Now we need to create a new arrow. 10:11.210 --> 10:15.950 Once this one being used, uh, we need to make a prefab of the arrow. 10:15.950 --> 10:17.840 So I'm going to just drag it here. 10:17.840 --> 10:24.320 And we could make functionality of an arrow creation in the arrow itself and somehow disable it and 10:24.320 --> 10:25.010 then enable it. 10:25.010 --> 10:29.720 But I don't really want to make object that will create itself, because then it will create clone of 10:29.720 --> 10:31.970 a clone, and then clone of a clone of a clone. 10:31.970 --> 10:34.130 And it's going to be like that endlessly. 10:34.130 --> 10:37.370 So I think I have no better choice for now. 10:37.370 --> 10:38.780 So I'm going to use Game Manager. 10:38.780 --> 10:41.300 Maybe later on we're going to have another object, another manager. 10:41.300 --> 10:42.320 We can use that. 10:42.320 --> 10:44.480 But for now I'm just going to use game manager. 10:44.480 --> 10:45.920 I'm going to make a header. 10:47.200 --> 10:48.100 Or traps. 10:48.100 --> 10:52.810 And I'm going to make public GameObject arrow prefab. 10:52.810 --> 10:56.260 Yeah just that and let's should we make a cool down here. 10:56.260 --> 11:00.970 Now I'm going to do cool down on a trap arrow, because we might want to set up cooldown of the arrows 11:00.970 --> 11:02.770 differently for different levels. 11:02.770 --> 11:08.980 So I'm going to just do prefab and let's go ahead all the way down here. 11:08.980 --> 11:11.710 And I'm going to make a method that will start a coroutine. 11:11.710 --> 11:17.350 So first I need private Ienumerator create object coroutine. 11:18.540 --> 11:19.650 In this quarantine. 11:19.650 --> 11:24.810 We want to pass game object because this can be used later on, not only for the arrow, but for something 11:24.810 --> 11:25.230 else. 11:25.230 --> 11:29.610 Like we don't know what is going to happen in the future, but it would be nice to set up things and 11:29.610 --> 11:30.630 be ready in the future. 11:30.630 --> 11:35.250 So game object prefab and we need float delay. 11:35.250 --> 11:37.200 We want to create object with a delay. 11:37.200 --> 11:40.170 Then I'm going to do yield return new. 11:40.170 --> 11:42.990 Wait for a seconds of delay. 11:43.530 --> 11:46.050 This should be delay. 11:46.050 --> 11:48.540 And then game object. 11:48.630 --> 11:51.630 New object equals to instantiate. 11:52.710 --> 11:53.610 Um, prefab. 11:53.610 --> 11:54.990 I guess we need position. 11:54.990 --> 11:56.100 Something that I forgot. 11:56.100 --> 12:01.050 So I'm going to do vector three position just like that. 12:01.050 --> 12:03.960 Now let's pass transform here. 12:03.960 --> 12:06.030 Transform target. 12:06.030 --> 12:13.110 And over here I'm going to make a vector three new position equals to target dot position. 12:13.110 --> 12:13.560 Yeah. 12:13.590 --> 12:17.010 Because otherwise we might destroy the object with the transform. 12:17.010 --> 12:18.870 And we would not be able to use it. 12:18.870 --> 12:22.410 That's why we store in transform in a vector three position. 12:22.410 --> 12:27.300 Over here we're going to use new position and quaternion identity for the rotation. 12:27.300 --> 12:28.230 Very nice. 12:28.230 --> 12:32.250 Now let's make a public method that will call this coroutine public void. 12:32.340 --> 12:35.160 Um create object. 12:35.190 --> 12:37.710 We're going to pass GameObject prefab. 12:37.710 --> 12:44.220 Then we're going to use uh transform target and Float Delay. 12:44.220 --> 12:46.680 And I want to give it a default value of zero. 12:46.680 --> 12:50.040 So if you don't pass any delay it's going to have no delay. 12:50.040 --> 12:52.080 If you pass some value it's going to have delay. 12:52.080 --> 12:58.470 Now here we're going to do start coroutine of create object coroutine with a prefab target and delay 12:58.470 --> 12:59.130 okay. 12:59.130 --> 13:00.000 Nothing new. 13:00.000 --> 13:03.360 We did all of this before just you know in different combination. 13:03.360 --> 13:07.080 Let's save this and then let's go to Trap Arrow. 13:08.270 --> 13:10.010 Open curly brackets here. 13:11.820 --> 13:19.560 And before we destroy the object, let's go ahead and make a reference to the arrow prefab. 13:20.280 --> 13:23.310 And I'm going to pull it from a game manager dot instance. 13:23.340 --> 13:24.480 Arrow prefab. 13:24.480 --> 13:30.450 Of course, I could make method specifically for the arrow on a game manager, but I want this method 13:30.450 --> 13:31.380 to be versatile. 13:31.380 --> 13:33.510 That's why I'm just passing game object here. 13:33.510 --> 13:38.100 And if I need arrow, I'm just pulling it from a game manager here. 13:38.130 --> 13:38.670 Okay. 13:39.870 --> 13:41.160 So that's what I'm doing. 13:41.160 --> 13:45.720 And then game manager dot instance create object of arrow prefab. 13:45.720 --> 13:47.970 We're going to pass transform of existing arrow. 13:47.970 --> 13:50.820 So it will replace itself with a new arrow. 13:51.240 --> 13:57.990 And for the cooldown let's make a variable serialize field private float cooldown. 13:57.990 --> 14:00.090 And we're going to pass it over here. 14:00.090 --> 14:01.050 Cooldown. 14:01.700 --> 14:02.510 All right. 14:02.510 --> 14:04.370 There is something else I want to do to improve it. 14:04.370 --> 14:08.120 But later on, let's just go ahead and try this for now. 14:08.510 --> 14:09.770 We're going to save it. 14:09.770 --> 14:11.570 Save everything actually. 14:11.570 --> 14:13.220 And let's go back to unity. 14:16.100 --> 14:17.180 On a game manager. 14:17.180 --> 14:22.400 We want to load the prefabs, and on the game manager we're going to assign this trap arrow. 14:23.370 --> 14:25.290 Then trap arrow over here. 14:25.290 --> 14:26.370 Let's do rotating rate. 14:26.370 --> 14:28.320 And let's say cooldown is 0.5. 14:28.320 --> 14:29.880 I just want to be sure it's working. 14:29.880 --> 14:32.790 So I'm going to create new arrows a lot. 14:34.370 --> 14:36.440 It's rotating and I'm going to go there. 14:38.140 --> 14:38.410 Ah! 14:38.410 --> 14:39.280 What is it? 14:40.100 --> 14:42.890 The object of type unity engine transform has been destroyed. 14:42.890 --> 14:44.930 But you still trying to access it? 14:46.300 --> 14:51.460 And this is what I was talking about, that we might destroy the transform and we're still trying to 14:51.460 --> 14:52.060 use it. 14:52.060 --> 14:52.570 Okay. 14:52.570 --> 14:57.970 Over here, we just need to move this line of code above so it will save vector three immediately before 14:57.970 --> 15:00.400 the delay, and then it's going to use it later on. 15:00.400 --> 15:01.180 Yes. 15:01.180 --> 15:02.440 Let's go now. 15:07.940 --> 15:13.280 Have the arrow going to jump into the arrow and it's going to create new arrow again. 15:13.280 --> 15:14.570 Very nice. 15:20.910 --> 15:24.480 Let's put higher cooldown on a prefab over here. 15:25.520 --> 15:26.000 Uh. 15:26.000 --> 15:26.930 It's zero. 15:26.930 --> 15:29.630 Let's do one and let's try. 15:33.270 --> 15:34.830 Yeah, okay. 15:35.580 --> 15:36.360 Very cool. 15:36.360 --> 15:37.320 It's working. 15:41.280 --> 15:42.000 I like it. 15:42.030 --> 15:45.120 Now there is something else I want to do to improve the arrow. 15:45.270 --> 15:52.920 And let's do a cooldown of 1.5 and let's do overwrite apply all so it will be applied to this arrow 15:52.920 --> 15:53.790 over here. 15:53.790 --> 15:59.670 I want to do something else here I want to gradually increase the scale of the arrow when it appears. 15:59.670 --> 16:04.080 So it's going to appear very small just like this. 16:04.080 --> 16:08.730 And then it's going to grow to the size it should have, and it's going to look real nice like it's 16:08.730 --> 16:09.600 popping out. 16:10.050 --> 16:12.600 Uh, for that we're going to use lerp. 16:12.600 --> 16:15.360 And you might never use lerp before. 16:15.360 --> 16:19.650 I'm going to explain briefly, but if you want to know more about lerp, I'm going to attach a video 16:19.650 --> 16:21.210 about lerp that I have. 16:21.210 --> 16:22.200 It's really a nice one. 16:22.200 --> 16:24.090 So if you want to know more, just check the video. 16:24.450 --> 16:31.080 Let's add a space over here and then let's type serialize field private float grow speed. 16:31.080 --> 16:33.450 And I'm going to make it equals to ten by default. 16:33.810 --> 16:40.320 And then also I want to have serialized field private vector three target scale okay. 16:40.320 --> 16:48.300 And then at the start we're going to do transform local scale equals to new vector three. 16:48.300 --> 16:52.110 And with this we changing scale of the transform. 16:52.660 --> 16:57.430 With a new vector that's going to be 0.3 f, 0.3 f, 0.3 f. 16:57.550 --> 17:03.340 Then in the update, let's take these two lines of code and rub them into a method. 17:03.580 --> 17:05.530 Handle rotation. 17:06.260 --> 17:11.000 Yeah, this one probably better be scale up speed. 17:11.030 --> 17:11.480 Yeah. 17:11.480 --> 17:12.140 Better. 17:13.480 --> 17:20.680 Now in the update, we cannot check entire vector like entire scale, but we can use scale X for example, 17:20.680 --> 17:23.140 and then use it to decide what we need to do next. 17:23.140 --> 17:31.300 So I'm going to do if transform local scale dot x is less than target scale, dot x means we need to 17:31.300 --> 17:36.280 scale up the object, and if we need to scale up the object, we're going to do transform local scale 17:36.280 --> 17:42.880 equals to Vector3 dot lerp and lerp is quite confusing in the beginning, but it's very easy to use. 17:43.420 --> 17:46.300 Uh, when you use an lerp, it's going to give you a value. 17:46.300 --> 17:51.340 You can usually say what you want to lerp, like you want to lerp from position A to position B. 17:51.340 --> 17:56.950 In our case, we want to lerp from a transform local scale that we have to the target scale. 17:58.340 --> 17:59.720 That we want to have. 18:00.530 --> 18:07.190 And then you need to decide, like the step you want to have sort of the percentage of the value you 18:07.190 --> 18:07.970 want to have. 18:07.970 --> 18:16.040 If you want to move from point A to point B and size of your step will be 30%, then you just set 0.3 18:16.040 --> 18:17.150 F, for example. 18:17.150 --> 18:21.170 Yeah, lerp always takes um, the percentage of value. 18:21.620 --> 18:22.610 Uh, look at this. 18:24.000 --> 18:29.010 Let's say I need to increase value gradually from 1 to 10. 18:29.800 --> 18:33.190 And size of the step will be 0.5. 18:33.220 --> 18:38.650 Okay, so the first time it's going to take half and it's going to be. 18:39.810 --> 18:41.430 Are removed. 18:41.460 --> 18:44.910 The next time I'm using lerp is going to take half again. 18:45.760 --> 18:50.140 The next time I'm using lerp is going to take half again because step size is 0.5. 18:50.820 --> 18:55.380 And like that huff huff huff huff. 18:55.380 --> 18:59.010 Because of that, it's going to look smooth, slow and nice. 18:59.340 --> 19:04.740 So over here I'm going to use scale up speed multiplied by time dot delta time. 19:06.420 --> 19:07.110 Okay. 19:07.730 --> 19:09.950 Very cool, I love it. 19:10.160 --> 19:12.290 Let's take these two lines of code. 19:12.290 --> 19:14.600 The extract method. 19:15.400 --> 19:17.440 Handle scale up. 19:18.770 --> 19:19.850 Just like that. 19:20.290 --> 19:22.810 Then we're going to go to the unity. 19:25.960 --> 19:32.020 Let's find prefab and make target scale 1.51.51.5. 19:33.280 --> 19:37.030 Now let's go destroy the arrow and see how it's going to. 19:37.060 --> 19:38.320 Yeah, that is very nice. 19:38.320 --> 19:39.310 You can see that. 19:40.970 --> 19:44.840 I'm going to you and it's growing like that. 19:44.840 --> 19:46.490 Really smooth and nice. 19:46.610 --> 19:48.740 Lerp can be used for many things. 19:49.880 --> 19:52.010 This is just one of the examples. 19:55.640 --> 19:57.320 Yeah, like how it turns out. 19:57.320 --> 19:58.640 Really cool mechanic. 19:59.800 --> 20:00.490 Need to wait. 20:00.490 --> 20:02.200 And then I need to bounce there. 20:02.200 --> 20:03.100 Yeah. 20:03.250 --> 20:04.300 All right. 20:04.420 --> 20:05.500 That's good for now. 20:05.500 --> 20:09.010 Let's save this and let's go to the next video.
