WEBVTT 00:00.040 --> 00:06.440 Now what we will do, we will collect this apple and we need to play that collected animation as we 00:06.480 --> 00:07.680 created earlier. 00:07.880 --> 00:15.120 So what we will do for that, I'm going to create a separate script for uh, for Collecting Apples heart 00:15.120 --> 00:16.640 and all of those things. 00:16.840 --> 00:21.800 To do that, we're going to move over to our project app assets and then script folder. 00:21.840 --> 00:26.280 Let's right click there, create uh create then go over to scripting. 00:26.320 --> 00:29.040 Then click on this Monobehaviour script. 00:29.080 --> 00:33.640 And you can name that script something like collectables or player collectibles. 00:33.760 --> 00:39.720 I already created a script called Player Collectibles, as you can notice right over here. 00:39.720 --> 00:42.600 So I'm going to select my player GameObject in the hierarchy. 00:42.600 --> 00:47.080 And let's select that script and drag it over to this Add Component section. 00:47.120 --> 00:48.640 Make sure you attach that. 00:48.680 --> 00:51.320 Or you can simply click on this add component. 00:51.320 --> 00:55.000 And you can find this script by typing name of the script. 00:55.000 --> 00:57.880 And then click on it in order to attach that. 00:58.000 --> 01:03.500 And now we're going to open up our player collectibles by double clicking on it, and we will go to 01:03.540 --> 01:04.900 top of our class. 01:04.900 --> 01:12.100 And we're going to declare a variable to just keep track of how many coins we sorry, how many apples 01:12.100 --> 01:13.620 we collected so far. 01:13.980 --> 01:20.380 So it doesn't need to be public, but for explanation, I'm just gonna make it public, and later on 01:20.380 --> 01:27.340 we're gonna make that feel private to just keep our code little bit a little bit clean. 01:27.340 --> 01:29.260 So we're going to make a serialized file. 01:29.540 --> 01:33.900 Uh, but before we do, let's give it a header or let's give it a title. 01:34.180 --> 01:36.420 So we're going to call it collect tables. 01:37.140 --> 01:37.660 Sorry. 01:37.900 --> 01:45.420 Inside quotation we're gonna say collect tables collect tables something like that. 01:46.020 --> 01:48.620 And we're going to make serialized will. 01:48.620 --> 01:53.500 And also I apologize if the spelling is wrong of collectibles. 01:53.900 --> 01:55.580 I really apologize for that. 01:55.780 --> 02:02.600 And this is going to be private and this will be integer like whole numbers zero, one, two, three, 02:02.640 --> 02:02.960 four. 02:03.160 --> 02:05.440 And we can call something like current. 02:05.480 --> 02:08.920 Apple's current app Apple's app. 02:09.480 --> 02:11.000 Sorry Apple's. 02:11.120 --> 02:13.320 And let's close that up with semicolon. 02:13.440 --> 02:16.000 And we're going to move over to this start function. 02:16.000 --> 02:19.240 So this start function get call in the start of the game. 02:19.240 --> 02:23.320 So in the start of the game we're going to set our current apples to zero. 02:23.360 --> 02:23.760 Why. 02:23.920 --> 02:28.240 Because in the start of the game right away we're not going to collect this apple. 02:28.240 --> 02:33.480 So that's why in the start of the game I'm gonna set current apples equal to zero. 02:33.680 --> 02:35.760 And then close that up with semicolon. 02:36.040 --> 02:39.240 And we're going to remove this update function we don't need. 02:39.280 --> 02:42.600 And we're going to use Ontriggerenter 2D function y. 02:42.880 --> 02:48.960 So if I move over to unity editor and then select this Apple game object, then go over to Inspector, 02:49.000 --> 02:50.720 then Circle Collider 2D. 02:50.760 --> 02:54.280 As you can see, we just check Ace Trigger to true. 02:54.280 --> 02:59.860 So that's why we're going to use Ontriggerenter 2D function instead of Oncollisionenter. 02:59.900 --> 03:00.940 2D function. 03:01.580 --> 03:09.260 So we're going to move over to our script, and we're going to use this on uh, on trigger a trigger 03:09.300 --> 03:10.780 into 2D function. 03:10.780 --> 03:14.540 So this function get called when we trigger with something we do know. 03:14.540 --> 03:20.140 And we get, we can extract information with this collision parameter what we trigger it with. 03:20.140 --> 03:23.700 So what we're going to do we're going to check the tag if it's Apple. 03:23.700 --> 03:29.820 And if we move over to unity and select this Apple GameObject in the hierarchy, then go over to Inspector. 03:29.860 --> 03:34.860 As you can notice, we just assigned this Apple GameObject as a Apple tag. 03:35.140 --> 03:36.420 So now what we're going to do. 03:36.460 --> 03:40.060 We're going to check the tag of the GameObject that we triggered it with. 03:40.100 --> 03:44.500 If that GameObject tag has a tag called Apple, then we need to collect that. 03:44.500 --> 03:46.500 So we're going to use this if condition. 03:46.500 --> 03:49.340 Let's make first bracket and some curly brackets. 03:49.340 --> 03:51.980 And what we're going to do over here we're going to check. 03:51.980 --> 03:54.360 So we will use this collision parameter. 03:54.920 --> 04:00.160 So we're going to type collision.com object and collision.com object over here. 04:00.200 --> 04:06.800 Basically means the game object player trigger it with and definitely player triggered are definitely 04:06.840 --> 04:09.800 player just gonna trigger with that Apple game object. 04:09.800 --> 04:14.920 So over here collision game object basically referencing that Apple game object. 04:14.920 --> 04:18.280 And now what we're gonna do we're gonna access the tag of it. 04:18.280 --> 04:24.200 So we're going to type this tag and we will check if the tag is equals equals to our apple. 04:24.360 --> 04:28.200 If that is the case then we need to collect our apple. 04:28.240 --> 04:34.920 But before we collect our apple we just want to check if we trigger it with that apple or not. 04:35.080 --> 04:37.000 So we're going to print out a message. 04:37.000 --> 04:39.960 So so for that we're going to type debug dot log. 04:40.080 --> 04:44.800 And we will say collect Apple something like that collect app. 04:45.600 --> 04:47.760 And let's close that up with semicolon. 04:47.960 --> 04:50.920 And we're going to press down Ctrl s on our keyboard. 04:50.920 --> 04:56.180 But before I do I'm just gonna arrange the and arrange this. 04:56.340 --> 04:58.900 You can say code to just keep it clean. 05:00.020 --> 05:01.580 I want just like this. 05:01.580 --> 05:02.420 So that's why. 05:02.700 --> 05:05.500 And we're going to press down Ctrl s to save our script. 05:05.500 --> 05:07.580 And now let's move over to unity. 05:07.980 --> 05:12.980 So as soon as we're going to trigger with this Apple game object, that message is going to pop up. 05:13.020 --> 05:13.420 Why? 05:13.580 --> 05:18.820 Because we assigned this apple as an Apple tag and we're checking there if we trigger it. 05:19.060 --> 05:21.380 The game object has a tag called Apple. 05:21.380 --> 05:27.420 If it is, then we just simply printing out that message as using which is a collect apple. 05:27.420 --> 05:33.700 So if I select my console tab and then click on this play button in the top in order to start our game, 05:33.700 --> 05:35.660 or in order to play our game. 05:35.660 --> 05:40.460 And you're gonna notice that as soon as we're going to trigger with this apple. 05:40.460 --> 05:43.100 So just wait a moment and you will see that. 05:44.460 --> 05:46.980 So let's trigger with this apple. 05:47.020 --> 05:52.630 As you can see, as soon as we trigger it we can see the message in our console tab. 05:52.630 --> 05:55.150 Just getting pop up says Collect Apple. 05:55.150 --> 05:59.550 So instead of printing out message, we just want to increase our apple. 05:59.550 --> 06:06.230 And also we need to trigger this trigger this if I select my Apple GameObject in the hierarchy. 06:06.670 --> 06:08.670 Uh, firstly let's get out of play mode. 06:09.270 --> 06:14.270 So if I select my apple and then this Apple icon. 06:14.270 --> 06:19.950 So the animator component is setting on this Apple icon game object, not the parent one. 06:19.990 --> 06:23.950 Basically it's just sitting on this Apple icon child game object. 06:24.190 --> 06:28.910 And this is our child and this will be our first child. 06:28.910 --> 06:33.390 And if you just duplicate this apple icon, then it's going to be the second child. 06:33.390 --> 06:35.190 And the index it off. 06:35.190 --> 06:36.950 It's just going to be one. 06:36.950 --> 06:41.350 So since this Apple icon index, uh, is a first child. 06:41.430 --> 06:46.630 So index uh, basically you can simply say the index of it, it's going to be zero. 06:46.830 --> 06:52.410 And if we duplicate this apple icon one more time than the duplicate one index. 06:52.450 --> 06:53.690 Gonna be sorry. 06:53.730 --> 06:56.810 The duplicate one index will be a one. 06:56.810 --> 06:59.770 So since we're looking for our this Apple icon. 06:59.770 --> 07:06.330 So as a child we need to pass zero because zero basically referencing the first child. 07:06.570 --> 07:12.530 And we can notice that if we select our Apple icon then go over to Inspector tab. 07:12.530 --> 07:16.610 We can see the animator component is setting on this Apple icon. 07:16.610 --> 07:21.250 So we need this animator component before we trigger this collected parameter. 07:21.250 --> 07:24.690 So we basically need to go over to this Apple icon GameObject. 07:24.690 --> 07:27.370 Basically the child of this Apple game object. 07:27.370 --> 07:29.770 And then we can just go over to animator. 07:29.770 --> 07:31.130 And we're gonna get that. 07:31.130 --> 07:32.690 And then we're going to trigger it. 07:32.690 --> 07:34.690 So let's open up our script. 07:34.690 --> 07:39.890 And instead of printing out message we just want to increase our current apples. 07:39.890 --> 07:43.410 So we're gonna set our current apples equals equals plus. 07:43.410 --> 07:46.370 Plus like that basically means adding one. 07:46.390 --> 07:50.190 So if we if we collect our first apple. 07:50.190 --> 07:54.070 So as you can notice in the start of the game, current apple is zero. 07:54.190 --> 07:58.430 So as soon as we get a trigger with that Apple we adding one. 07:58.430 --> 08:02.630 As you can notice current Apple Plus plus basically adding one. 08:02.630 --> 08:06.550 So it's going to be something like zero plus one zero plus one. 08:06.550 --> 08:11.790 We do know it's going to be one means we just increasing our current apples. 08:11.790 --> 08:18.710 And after increasing that what we need to do we need to trigger this collected parameter and this. 08:18.910 --> 08:25.230 And we can notice that animator component is sitting on this tile game object of this Apple game object. 08:25.230 --> 08:26.790 So we need to get the tile. 08:26.790 --> 08:30.350 And to get the child we basically have to use a transform. 08:30.510 --> 08:35.710 And this is since this is the only child or this is the first tile you can say. 08:35.710 --> 08:38.630 So the index of it's going to be zero. 08:38.630 --> 08:44.230 So let's go to our script and we're going to use this collision dot game object and collision dot game 08:44.270 --> 08:47.690 object over here basically means the Apple game object. 08:47.690 --> 08:50.250 So we need to get to the tile game object. 08:50.250 --> 08:54.250 And in order to get that we're going to use dot transform. 08:54.450 --> 08:57.850 And then dot we're going to use this get tile function. 08:57.850 --> 09:00.890 And in these brackets we need to pass the index. 09:00.890 --> 09:07.010 So what we simply doing we just going over to this Apple game object first then going over to transform. 09:07.050 --> 09:09.130 As you can notice in Inspector. 09:09.130 --> 09:12.930 And by this transform we're just getting the tile as you can see. 09:13.170 --> 09:15.530 So we're looking for this Apple icon. 09:15.530 --> 09:19.850 And the Apple icon index is going to be zero since this is our first tile. 09:19.850 --> 09:20.890 So that's why. 09:21.090 --> 09:26.530 So inside this get tile function we're going to pass zero basically means that Apple icon game object 09:26.530 --> 09:28.370 which is going over to that. 09:28.370 --> 09:31.450 And now what we're going to do we're going to type this game object. 09:31.650 --> 09:34.250 And we need to get the animator component. 09:34.250 --> 09:37.170 So we're going to use this dot get component. 09:37.170 --> 09:39.770 And the component we're looking for is animator. 09:39.770 --> 09:41.090 So make this arrows. 09:41.090 --> 09:45.990 And inside this arrows just pass the component you are looking for. 09:46.070 --> 09:47.670 So we're looking for animator. 09:47.670 --> 09:49.510 So we're going to type this animator. 09:49.750 --> 09:53.950 Sorry animator animator. 09:53.950 --> 09:57.590 And then make this first bracket and then what we're going to do. 09:57.590 --> 10:01.110 So now we have a reference of that animator component. 10:01.110 --> 10:04.430 So we need to trigger that collected parameter. 10:04.430 --> 10:08.790 And in order to trigger that we need to use dot set trigger function. 10:08.790 --> 10:10.990 And this set trigger function in brackets. 10:10.990 --> 10:14.470 It's going to take the parameter name inside quotation. 10:14.470 --> 10:18.630 And make sure you just go to unity editor and check the parameter name. 10:18.630 --> 10:21.510 And we can notice that we have the parameter name. 10:21.550 --> 10:28.710 Sorry, we have the parameter name collected as you can notice inside our animator tab. 10:28.710 --> 10:31.150 So now let's move over to our script. 10:31.390 --> 10:36.750 And inside this quotation we're going to pass our uh parameter name. 10:36.750 --> 10:39.870 So the parameter name is collected. 10:39.870 --> 10:41.930 And make sure you spelling it Correct. 10:41.970 --> 10:46.330 Else it's not gonna work and press down Ctrl S to save your script. 10:46.330 --> 10:46.890 And then. 10:47.370 --> 10:49.450 And then let's move over to unity. 10:49.650 --> 10:52.570 So let's go over to unity and we will see. 10:52.570 --> 10:54.050 So what we simply doing. 10:54.090 --> 10:59.130 Firstly we going over to this Apple game object then going over to transform. 10:59.130 --> 11:05.650 And by this transform we just going over to this animator component basically firstly we just moving 11:05.650 --> 11:07.570 over to this Apple game object. 11:08.290 --> 11:11.770 Sorry Apple game object transform as you can see. 11:11.810 --> 11:16.370 And by this transform we're just going over to this Apple icon game object. 11:16.370 --> 11:18.330 And then this animator component. 11:18.330 --> 11:20.570 As you can notice in Inspector. 11:20.570 --> 11:25.450 And by getting this animator component we just triggering this collected parameter. 11:25.450 --> 11:28.770 As you can notice in our animator tab. 11:29.010 --> 11:31.410 And now let's see what's gonna happen. 11:31.410 --> 11:38.450 And I'm gonna select my player GameObject in the hierarchy to able to see my player collectibles script. 11:38.450 --> 11:43.430 As you can notice in the inspector, uh, inside this player game object. 11:43.430 --> 11:45.710 So current apples by default is zero. 11:45.710 --> 11:49.990 So let's click on this play button in the top in order to play our game. 11:49.990 --> 11:55.470 So as soon as we're going to collect this parameter you will see current Apple just gonna increase by 11:55.470 --> 11:55.990 one. 11:55.990 --> 12:02.150 And after that we just playing that animation clip which is the collected as you seen earlier that we 12:02.190 --> 12:02.990 created. 12:03.350 --> 12:05.790 Uh, so we're gonna collect this apple. 12:06.070 --> 12:11.910 So as you can see, as soon as we just triggered it with that current apples, we can notice current 12:11.950 --> 12:15.030 apples is one and it's became two. 12:15.190 --> 12:15.670 Why? 12:15.870 --> 12:23.230 Because we need to disable the current apples Collider 2D, uh, as soon as we're gonna collect that. 12:23.230 --> 12:30.390 So that's why if I just, uh, trigger one more time, as you can see, our current apples just keep 12:30.390 --> 12:31.070 increasing. 12:31.070 --> 12:36.950 Because if we move over to hierarchy, we can see Apple game object is still in the scene view. 12:36.990 --> 12:41.570 And you can notice right over here if I select the move tool in the scene view. 12:41.850 --> 12:49.010 As you can notice, the Circle Collider is still still over here, as well as the sprite or this Apple 12:49.010 --> 12:51.090 GameObject is still in the game view. 12:51.250 --> 12:54.610 So after some period of time, we need to destroy that. 12:54.770 --> 12:59.410 And we do know that collected animation clip just playing for one second. 12:59.450 --> 13:05.170 So after one second we just want to you can simply say want to destroy. 13:05.170 --> 13:12.010 But before we destroy, we need to disable this Collider 2D as we attach inside this Apple GameObject. 13:12.010 --> 13:18.890 And we do know that as soon as we're gonna collide with that, we just keep increasing our current apples. 13:18.970 --> 13:25.610 So if I just trigger one more time, as you can notice underneath our player collectible script in Inspector 13:25.650 --> 13:27.850 Current, apples became one four. 13:27.890 --> 13:30.850 And if we trigger one more time, it became five. 13:30.850 --> 13:38.110 So we need to disable that circle Collider 2D of this Apple game object as soon as we're gonna trigger 13:38.110 --> 13:38.750 with that. 13:38.750 --> 13:44.710 And after that, once again, we're just gonna destroy our apple from the scene view as well as in the 13:44.710 --> 13:47.190 hierarchy as well as in the game view. 13:47.390 --> 13:49.390 Sorry, scene view and game view. 13:49.390 --> 13:51.190 So let's get out of play mode. 13:51.190 --> 13:55.630 And for that, what we're gonna do, we're gonna move over to our script over here. 13:55.630 --> 13:57.670 As you can notice, we're collecting. 13:57.710 --> 14:04.670 After collecting that, we're gonna disable our, uh, basically the Circle Collider 2D of that Apple, 14:04.830 --> 14:05.950 uh, game object. 14:05.950 --> 14:08.670 So we're going to use this collision dot game object. 14:08.670 --> 14:13.790 And we do know that collision dot game object basically means the game object we trigger it with. 14:13.790 --> 14:16.310 So in our case it's going to be the apple. 14:16.470 --> 14:21.510 And now what we're gonna do we're gonna get this component or circle Collider 2D. 14:21.510 --> 14:25.150 So we're going to use this dot get component and make these arrows. 14:25.150 --> 14:29.670 And inside these arrows you need to pass the component name that we're looking for. 14:29.790 --> 14:36.010 So if I select my Apple GameObject in the hierarchy then go over to Inspector then Circle Collider 2D. 14:36.050 --> 14:41.850 As you can see, we need this circle Collider 2D and we need to set the enable basically uncheck. 14:41.850 --> 14:46.290 Basically we need to disable that as soon as we're going to trigger with that. 14:46.410 --> 14:48.810 So that's why we're inside these arrows. 14:48.810 --> 14:51.090 We're going to pass this circle Collider 2D. 14:51.130 --> 14:55.490 Because this circle Collider 2D is attached to that Apple game object. 14:55.490 --> 14:57.530 And now we're going to make this brackets. 14:57.730 --> 15:01.930 And to get that and now let's use dot enabled. 15:01.930 --> 15:05.570 So make sure you just use this dot enable. 15:05.770 --> 15:12.250 And if you set equal to false it's basically means you just disabling that circle Collider 2D. 15:12.570 --> 15:19.730 And if you pass true instead of false that A that's basically means you enabling that circle collider 15:19.770 --> 15:20.250 2D. 15:20.370 --> 15:22.370 So since we want to disable. 15:22.370 --> 15:27.970 So that's why we just type dot enable equal to false, we basically disabling that. 15:28.250 --> 15:33.780 And after disabling that we also need to destroy that Apple game object. 15:33.780 --> 15:36.500 And we do know that it's playing after. 15:36.780 --> 15:42.060 So the collected animation clip just playing uh or playing with one second. 15:42.060 --> 15:46.460 So after one second, we also need to destroy the Apple game object itself. 15:46.620 --> 15:52.260 And to destroy, we're gonna use this destroy function and this destroy function as a first argument. 15:52.260 --> 15:57.860 It's going to take the game object that we want to destroy, since we want to destroy our Apple game 15:57.900 --> 15:58.260 object. 15:58.260 --> 16:02.620 So we're going to pass this collision dot game object means the Apple game object. 16:02.740 --> 16:04.020 And second thing comma. 16:04.020 --> 16:05.940 We can specify the time. 16:05.940 --> 16:12.060 And if you don't specify the time and you just close that off with semicolon, that means Apple just 16:12.060 --> 16:19.540 gonna destroy it right away, which we don't want since we want to play the collected animation clip 16:19.540 --> 16:20.580 of that Apple. 16:20.580 --> 16:25.860 So that's why as a second argument, we're going to pass one F basically means after one second we're 16:25.860 --> 16:28.260 destroying our Apple game object. 16:28.260 --> 16:30.540 And now we're going to close that up with semicolon. 16:30.600 --> 16:33.720 And let's press down Ctrl s to save our escape. 16:33.760 --> 16:35.600 And now let's move over to unity. 16:35.720 --> 16:39.040 So as soon as we're gonna collect this file. 16:39.280 --> 16:42.840 Firstly, we're disabling the Circle collider 2D of this apple. 16:42.840 --> 16:46.600 And after that we are destroying this Apple GameObject. 16:46.680 --> 16:49.200 Uh, one second after one second. 16:49.200 --> 16:50.960 So just wait a moment. 16:52.360 --> 16:54.320 Uh, so just wait a moment. 16:54.320 --> 17:00.320 And if I select my player game object in the hierarchy, we can notice player collectibles are underneath 17:00.360 --> 17:01.000 our player. 17:01.000 --> 17:02.320 Collect collectibles. 17:02.320 --> 17:04.600 Script current apples is zero. 17:04.600 --> 17:08.720 So let's click on this play button in the top in order to play our game. 17:08.720 --> 17:15.880 And let's collect this, uh, apple uh, or let's trigger with this apple as soon as we can, as soon 17:15.880 --> 17:16.640 as possible. 17:16.640 --> 17:17.840 We're gonna collect that. 17:18.240 --> 17:25.080 So now if we collect this apple, as you can see, current apples became one. 17:25.080 --> 17:31.780 And we cannot able to notice our apple in this in interview, as well as in the game view as well as 17:31.780 --> 17:32.660 in the hierarchy. 17:32.820 --> 17:39.300 As you can notice, underneath our hierarchy tab, we are not able to notice our Apple game object since 17:39.300 --> 17:41.300 we totally destroyed that. 17:41.460 --> 17:47.300 So I hope you get the idea that how you can do it, and I'm gonna get out of play mode and you can do 17:47.300 --> 17:55.020 the same thing with our basically with player health, we're gonna do this same thing with our player 17:55.020 --> 18:03.780 health and make sure you, uh, basically, uh, press down control s in order to save your project. 18:03.820 --> 18:10.260 But before I save my project, I'm gonna create an empty game object, and I'm gonna name that game 18:10.260 --> 18:12.380 object to something like collectables. 18:12.380 --> 18:18.580 And I will track all of the collectables into that game object in order to make our hierarchy clean 18:18.580 --> 18:21.660 or to, uh, to keep our project clean. 18:21.780 --> 18:22.980 So let's do that. 18:22.980 --> 18:28.280 To do that, we're gonna move over to hierarchy, right click or hit this plus icon, then create an 18:28.320 --> 18:33.400 empty game object and we're going to name this game object something like collectables. 18:33.600 --> 18:36.320 So let's call it collectables. 18:36.680 --> 18:38.920 Let's go over to Inspector Transform. 18:38.920 --> 18:40.880 Let's right click and then reset. 18:41.080 --> 18:44.360 And I'm going to choose an icon for that like this. 18:44.680 --> 18:50.160 And you can notice right over here and I'm going to select my collectables GameObject in the hierarchy 18:50.200 --> 18:50.800 hierarchy. 18:50.800 --> 18:54.200 And let's drag it in the top so we can see all the time. 18:54.200 --> 18:57.400 And now I'm going to take my Apple GameObject in the hierarchy. 18:57.520 --> 19:01.320 And let's drag it off of this collectable game object. 19:01.360 --> 19:02.160 Now it's done. 19:02.160 --> 19:04.880 And we can just click over here to just collapse. 19:04.880 --> 19:09.840 And as you can notice by now, our hierarchy seems a lot more clean. 19:09.840 --> 19:16.200 So once we're gonna have the, uh, the heart animation, a heart game object, uh, because that, 19:16.200 --> 19:22.120 uh, that's just going to be a collectible so we can just drag it on top of this collectables game object 19:22.120 --> 19:26.280 to just keep our project clean and the hierarchy, basically.
