WEBVTT 00:00.040 --> 00:02.080 We need a reference of this text. 00:02.120 --> 00:05.040 This Apple text as well as this text. 00:05.080 --> 00:08.160 We need a reference, a reference of it. 00:08.160 --> 00:09.240 Then we can change. 00:09.400 --> 00:16.400 So if I move over to my hierarchy then canvas and then select this UI and then go over to this current 00:16.440 --> 00:18.320 Apple text current Apple text. 00:18.320 --> 00:21.520 Then go over to Inspector and then Text component. 00:21.520 --> 00:23.560 And we can change the value over here. 00:23.560 --> 00:24.800 We can set it to one. 00:24.800 --> 00:25.960 We can set it to two. 00:26.000 --> 00:27.360 We can set it to three. 00:27.480 --> 00:32.520 So basically what we need we need to go over to this current Apple text game object first. 00:32.520 --> 00:34.480 And then we need to access this text. 00:34.480 --> 00:40.160 And we're going to set this text equal to our current apples we have collected so far. 00:40.360 --> 00:46.200 So if I select my player GameObject in the hierarchy then go over to Player Collectible Script in in 00:46.240 --> 00:47.640 in in Inspector. 00:47.680 --> 00:52.840 As you can notice we have current apples zero and we showing up over here. 00:52.840 --> 00:55.960 So we also need to update this in the UI. 00:56.000 --> 00:58.600 Basically we need to set this current UI. 00:58.640 --> 01:04.280 Basically this current Apple text with our, uh, this, uh, current apples. 01:04.280 --> 01:07.400 So we need to do that to do to get the reference. 01:07.400 --> 01:09.640 So let's open up our script first. 01:09.640 --> 01:13.240 So we're going to move over to our player GameObject in the hierarchy. 01:13.440 --> 01:18.120 And let's open up the player collectible script in the Inspector by double clicking on it. 01:19.120 --> 01:21.720 And we will go to the top of our class. 01:21.720 --> 01:25.520 And we're gonna, we're gonna get that text component. 01:25.520 --> 01:31.360 And before you get the text component, make sure you just go to top of your class and include this 01:31.360 --> 01:34.480 namespace called using Unity Engine dot UI. 01:34.680 --> 01:39.360 So whenever you're working with UI, make sure you include this namespace. 01:39.360 --> 01:45.200 It's called using Unity Engine UI because that text element is a UI element. 01:45.200 --> 01:46.160 So that's why. 01:46.480 --> 01:54.440 So we're going to make a serialized field, sorry, serialized field, uh, a private and a component 01:54.440 --> 01:56.520 that we're looking for is a text type. 01:56.520 --> 02:01.440 So we're going to type this text and we can call this one something like Current Apple Text. 02:01.440 --> 02:07.480 So let's call it current Apple Text and then close that up with semicolon. 02:07.480 --> 02:12.080 And we're going to press down Ctrl s on our keyboard in order to save our script. 02:12.080 --> 02:14.000 And now let's move over to unity. 02:14.400 --> 02:19.440 So underneath our player collectible script and another field just going to pop up. 02:19.600 --> 02:24.680 And it will be current Apple Text as we name it the parameter or the variable. 02:25.240 --> 02:29.760 So what we need we need to drag this current Apple text into that slot. 02:29.760 --> 02:31.520 So we will have the reference. 02:31.520 --> 02:35.320 And after that we can link that up with our current apples. 02:35.680 --> 02:41.440 So now we can see underneath our player collectible collectible script it will be null like this. 02:41.480 --> 02:42.000 Empty. 02:42.040 --> 02:46.360 So what you need to do you need to drag the text component right over here. 02:46.800 --> 02:51.320 And we do know that if we select this current Apple text then go over to Inspector. 02:51.320 --> 02:57.200 We can see the text text component is sitting on its current Apple text game object. 02:57.200 --> 03:00.480 So that's why we need to drag this GameObject into that field. 03:00.520 --> 03:03.120 So we're going to select our player collectible script. 03:03.120 --> 03:07.920 And let's select this current Apple text and then drag it over to that slot. 03:07.920 --> 03:11.400 And now we can see we have the current Apple text reference. 03:11.400 --> 03:14.360 Basically this text component as you can see. 03:14.640 --> 03:17.000 And now we are ready to set that up. 03:17.160 --> 03:19.840 So what we're going to do we're going to open up our script. 03:20.440 --> 03:23.960 And we need to move over to in which line of code we doing. 03:23.960 --> 03:27.640 Basically collecting our apples right over here. 03:27.640 --> 03:31.400 You can notice we just increasing our current apples. 03:31.400 --> 03:34.120 So we also need to update that in the UI. 03:34.280 --> 03:39.120 So basically what we have to do we need to go over to this current Apple text game object first. 03:39.280 --> 03:41.800 And then we need to access this text. 03:41.800 --> 03:45.520 And we need to set this text equal to our current apples. 03:45.840 --> 03:49.720 And basically means how many apples we have right now. 03:49.960 --> 03:51.960 So let's go over to our script. 03:52.040 --> 03:57.200 So after collecting the apples we're going to move over to that current Apple text game object. 03:57.200 --> 03:59.600 And now we're going to access the text component. 03:59.600 --> 04:01.400 So by dot text. 04:01.400 --> 04:04.800 And we're going to set equal to our current Apple tax. 04:04.840 --> 04:06.240 Sorry, not current Apple. 04:06.840 --> 04:11.880 We basically need to set this current apples and close that up with semicolon. 04:12.040 --> 04:17.440 But the problem is that this one over here, as you can see it, this is an integer value. 04:17.440 --> 04:23.000 So if we go to top of our class we can see this current apples is a integer value. 04:23.040 --> 04:24.760 We can notice right over here. 04:24.920 --> 04:27.760 And this right over here is a string value. 04:27.880 --> 04:31.120 So we need to convert this integer value to a string. 04:31.120 --> 04:32.560 So how we can do that. 04:32.600 --> 04:36.200 We basically need to type after current apples dot two string. 04:36.200 --> 04:39.240 And this function just gonna convert a string value. 04:39.640 --> 04:39.920 Sorry. 04:39.960 --> 04:42.520 It's gonna convert integer value to a string. 04:42.520 --> 04:44.480 Now this is a string value. 04:44.480 --> 04:48.000 So we firstly going over to current Apple text game object. 04:48.000 --> 04:50.200 Then we accessing the text component. 04:50.200 --> 04:53.000 And we're setting equal to our current apples. 04:53.000 --> 04:55.920 So let's suppose this current apple something like five. 04:55.960 --> 04:59.920 Then this current apple text text right over here five. 04:59.960 --> 05:00.280 Why. 05:00.320 --> 05:02.880 Because we directly setting it as you can see. 05:03.160 --> 05:07.000 So firstly we're just going over to this current Apple text game object. 05:07.240 --> 05:12.320 Then we accessing this text and we're setting this text equal to our current apples. 05:12.360 --> 05:14.560 As you can see right over here. 05:14.560 --> 05:17.080 So that's why it's going to update in the UI. 05:17.360 --> 05:21.840 And we're going to press down Ctrl s on our keyboard in order to save our script. 05:21.840 --> 05:25.800 And make sure you just move over to unity and check that out. 05:26.000 --> 05:31.800 So as soon as we're going to collect the first apple, we will be able to notice our current Apple text 05:31.800 --> 05:32.840 gonna be one. 05:32.840 --> 05:35.960 And if we collect second Apple, then it's gonna be two. 05:35.960 --> 05:37.120 And so on. 05:37.400 --> 05:40.040 So you can check with many apples you want. 05:40.080 --> 05:42.000 I'm gonna duplicate this apple. 05:42.040 --> 05:46.800 So I will move over to hierarchy and let's go to. 05:47.920 --> 05:48.520 Sorry. 05:48.560 --> 05:50.800 We, uh, have the Apple. 05:51.040 --> 05:53.600 So if collectibles right over here. 05:53.600 --> 05:57.840 So I'm going to select this heart and let's press down Ctrl D to duplicate. 05:57.840 --> 06:00.880 And we're going to press down F in order to focus on it. 06:00.880 --> 06:03.080 And let's select the move tool in the scene view. 06:03.520 --> 06:06.320 Sorry we duplicated this heart. 06:06.320 --> 06:07.680 So I'm going to delete that. 06:07.680 --> 06:09.960 I'm going to select the apple in the hierarchy. 06:10.120 --> 06:12.640 And let's press down Ctrl D to duplicate. 06:12.640 --> 06:15.400 And let's move it over somewhere around here. 06:15.800 --> 06:17.880 And I'm gonna duplicate one more time. 06:17.880 --> 06:19.240 Let's move it here. 06:19.240 --> 06:21.120 So we have three apples. 06:21.120 --> 06:27.360 So as soon as we're gonna collect the first one our current apple is gonna be one. 06:27.360 --> 06:30.280 And if we collect the second one, then it's gonna be two. 06:30.320 --> 06:33.320 And if we collect the third one, then it's gonna be three. 06:33.520 --> 06:34.960 So let's check that out. 06:34.960 --> 06:39.520 So I'm going to click on this play button in the top in order to play our game. 06:39.520 --> 06:41.520 And let's take a look on this. 06:41.520 --> 06:46.400 So as soon as we're gonna collect the first one our current Apple text will be one. 06:46.680 --> 06:49.760 And if we collect the second one then it's gonna be two. 06:50.200 --> 06:52.040 So if we collect the first one. 06:52.040 --> 06:53.800 So let's try to collect this. 06:53.800 --> 06:59.120 As you can see, as soon as we collect it, this current apple takes right over here. 06:59.120 --> 07:05.480 If I select my canvas in the hierarchy and press down F in order to focus on it, we can notice that 07:05.480 --> 07:08.920 this current Apple tax is now one. 07:08.920 --> 07:13.160 And if we try to collect the second one now we can see it's now two. 07:13.360 --> 07:16.360 And if we collect the third one then it should be three. 07:16.360 --> 07:21.320 So if we sorry if we collect the third we can see now it's became three. 07:21.600 --> 07:24.400 So I hope you get the idea that how you can do it. 07:24.400 --> 07:27.840 And we're gonna do the same thing as well with our heart. 07:27.840 --> 07:31.040 So let's get out of play mode and let's do the same thing. 07:31.040 --> 07:37.160 So firstly, what we need if we move over to our hierarchy canvas and then UI game object and select 07:37.160 --> 07:43.000 this heart text, we can see that the text component is setting on this heart text game object. 07:43.000 --> 07:45.920 So we need a reference of this text component. 07:45.920 --> 07:50.280 And after that we can just link that up with our player Maxell. 07:50.320 --> 07:56.000 So we're gonna open up our script and let's go to top of our class and let's grab the reference. 07:56.000 --> 07:59.280 So we're gonna make another serialized field private. 07:59.280 --> 08:01.840 And the component we're looking for is a text type. 08:01.840 --> 08:08.390 So we're going to type this text and we're going to call this one current, uh, current, uh, let's 08:08.390 --> 08:12.110 call it current health, uh, health text, something like that. 08:12.110 --> 08:17.390 And we're going to close that up with semicolon and make sure once you press down Ctrl S, then move 08:17.390 --> 08:22.830 over to unity underneath your, uh, player collectible script, you're gonna able to notice that, 08:22.830 --> 08:30.150 uh, sorry if I select my, uh, player GameObject in the hierarchy, and I need your player collectible 08:30.150 --> 08:33.750 script or wherever you just made it, you're gonna see that fill. 08:33.750 --> 08:35.750 So make sure you drag the reference. 08:35.950 --> 08:40.390 So after grabbing the reference now what we need to do, we need to set that up. 08:40.510 --> 08:43.870 And we're going to set this up with our update function. 08:43.870 --> 08:47.310 And also we need a reference of our player's game. 08:47.310 --> 08:52.030 So if I select my player game object then go over to Inspector then player skip. 08:52.070 --> 08:56.150 We can see inside this player script we have the max health. 08:56.190 --> 08:58.830 So we need a reference of this player skip. 08:58.830 --> 09:00.750 Then we can just grab the reference. 09:00.750 --> 09:02.910 So make sure you just grab the reference. 09:02.910 --> 09:05.790 And we do know that we already done it. 09:05.790 --> 09:08.950 So if I open up my player collectible script. 09:08.950 --> 09:13.310 As you can see, we already grabbed the reference in the start function. 09:13.310 --> 09:18.070 As you can notice, firstly, we just created a variable for our player script. 09:18.070 --> 09:20.310 As you can see private player player. 09:20.550 --> 09:25.590 And then we just moving over to start function and we're just taking our player script. 09:25.590 --> 09:29.710 As you can notice this dot game object basically referencing itself. 09:29.910 --> 09:36.110 And we're just getting the player script component or player script and we're storing into this player 09:36.110 --> 09:37.350 as you can notice. 09:37.350 --> 09:38.910 So we already done it. 09:38.910 --> 09:42.070 And now what we have to do, we need to update in the UI. 09:42.230 --> 09:45.270 To do that we're going to move over to this update function. 09:45.270 --> 09:49.030 So update function runs every single frame and every single frame. 09:49.030 --> 09:52.550 We need to update the health in the UI text. 09:52.550 --> 09:56.630 So what we're going to do now we are gonna do this thing. 09:56.670 --> 10:00.150 Firstly we will go to current uh health text. 10:00.190 --> 10:02.070 And then we're going to access the text. 10:02.070 --> 10:06.910 And we're gonna set equal to our player Dot Max hell. 10:06.950 --> 10:09.270 And we're going to close that up with semicolon. 10:09.510 --> 10:14.510 So we're getting the same error, which is uh, this is integer value right over here. 10:14.510 --> 10:16.670 So if I move over to my player script. 10:16.790 --> 10:21.590 So we basically accessing this player and we sorry accessing this max cell. 10:21.590 --> 10:25.110 And as you can notice this max cell is a int parameter. 10:25.110 --> 10:25.910 We can see. 10:26.270 --> 10:32.750 So so what we're doing simply over here we're just going over to their player max cell. 10:32.870 --> 10:34.630 So this is integer value. 10:34.670 --> 10:37.790 Now we need to convert this into a string value. 10:37.790 --> 10:42.510 To convert that we need to type this dot to string and then make this first bracket. 10:42.670 --> 10:45.510 So firstly we just going over to current text. 10:45.550 --> 10:48.710 Basically we're just going over to this UI. 10:48.750 --> 10:52.190 Then this heart text heart text game object. 10:52.190 --> 10:55.350 And we accessing the text component in Inspector. 10:55.350 --> 10:56.510 As you can notice. 10:56.510 --> 11:00.550 And we setting this text component equal to our player max cell. 11:00.550 --> 11:03.670 And let's suppose player max is something like three. 11:03.710 --> 11:08.870 Then this right over here it's gonna be three because we directly setting it, as you can notice. 11:09.350 --> 11:12.350 Uh, really sorry. 11:12.750 --> 11:18.630 So firstly we going over to current health text and we accessing the text component. 11:18.630 --> 11:21.430 And we setting equal to our player Max health. 11:21.510 --> 11:25.590 So the text will be changed according to our player max health setting. 11:25.870 --> 11:31.430 Since we just directly setting it or we just setting it equal to this as you can notice. 11:31.590 --> 11:36.590 And now we're going to press down Ctrl s on our keyboard in order to save our script. 11:36.590 --> 11:38.550 And now let's move over to unity. 11:38.750 --> 11:45.350 So underneath our player collectible script we will able to notice another field just going to pop up 11:45.350 --> 11:48.190 which is current uh health text. 11:48.190 --> 11:53.990 So what we need to do there, we basically need to drag this text game object into that field. 11:53.990 --> 11:58.910 Since the text component is sitting on inside this heart text game object. 11:58.950 --> 12:01.990 Now we're going to select our player game object in the hierarchy. 12:02.190 --> 12:03.910 And let's select this player script. 12:03.950 --> 12:09.910 As you can notice underneath our player collectible script we able to notice a current health text and 12:09.910 --> 12:11.870 it says none basically empty. 12:11.870 --> 12:15.070 So we're going to take our health text and drag it over there. 12:15.110 --> 12:16.590 Now we have the reference. 12:16.590 --> 12:20.030 And now we're going to be able to check it in key. 12:20.230 --> 12:25.110 So if I just go ahead and then click on this play button in the top, you will notice that. 12:25.390 --> 12:29.070 So as soon as we're going to collect the this heart the first. 12:29.070 --> 12:31.150 But we're not gonna able to do it. 12:31.190 --> 12:31.670 Why. 12:31.990 --> 12:38.510 Because the if the max health of this uh player game object is already five, then we're not taking. 12:38.510 --> 12:44.990 So as you can see, as soon as the game started, we can see player Max health is five just updated 12:44.990 --> 12:45.790 in the UI. 12:45.830 --> 12:46.310 Why? 12:46.510 --> 12:52.790 Because if I select my player GameObject in the hierarchy, then go over to Inspector, then player 12:52.790 --> 12:53.270 Skip. 12:53.470 --> 12:58.910 Because in the start of the game we setting player max which is five as you can notice. 12:58.910 --> 13:05.070 So that's why this text right over here, it's became five because, uh, we do know that inside our 13:05.070 --> 13:09.470 skip, we just directly setting it, as you can see right over here. 13:09.670 --> 13:16.110 So now if I drag down a little bit, basically if I make, I make the max health of this player game 13:16.150 --> 13:17.630 object something like four. 13:18.070 --> 13:23.630 But before we do that, if we try to collect our heart, we not able to do it. 13:23.630 --> 13:29.310 So because we already have the max health is five and we're checking if the max health of this player 13:29.350 --> 13:33.310 game object is already five, then we're not collecting at all. 13:33.310 --> 13:35.230 So let's make it something like four. 13:35.270 --> 13:38.030 So I'm going to select my player game object in the hierarchy. 13:38.230 --> 13:41.470 Let's go over to Inspector then player Skip and the max. 13:41.470 --> 13:43.550 Well I'm gonna make it something like four. 13:43.750 --> 13:45.910 Now as soon as I just type four. 13:45.950 --> 13:49.590 It just updated in the UI because we directly setting it. 13:49.590 --> 13:52.030 And now we will able to collect this. 13:52.030 --> 13:57.110 So if I collect this heart, as you can see, as soon as we collect it, it disappeared. 13:57.110 --> 14:00.230 And we can see the max health of this player game objects. 14:00.270 --> 14:01.790 Now it's became five. 14:02.070 --> 14:07.550 So I hope you get the idea that how you can link up your UI text with script. 14:07.550 --> 14:09.350 So I'm gonna get out of play mode.
