WEBVTT 00:00.080 --> 00:01.600 Let's create our coin. 00:01.640 --> 00:08.120 So I have the coin sprite in my UI folder, as you can see in project tab and then assets folder. 00:08.240 --> 00:09.840 So I'm going to select my this coin. 00:09.840 --> 00:11.600 So let's select this coin sprite. 00:11.640 --> 00:12.880 Let's go to Inspector. 00:12.880 --> 00:15.120 Click on this open Sprite editor. 00:15.280 --> 00:17.120 So we can see we have more than one. 00:17.120 --> 00:18.720 So we're going to slice individually. 00:18.720 --> 00:22.680 So we'll choose sprite mode to multiple filter mode to point no filter. 00:22.680 --> 00:24.360 And let's click on this apply. 00:24.680 --> 00:26.720 And let's slice it individually. 00:26.720 --> 00:30.160 Basically what we're going to do we're going to slice grid by cell count. 00:30.360 --> 00:32.000 So let's click on this slice. 00:32.000 --> 00:34.840 We're going to choose automatic to create by cell count. 00:34.880 --> 00:38.000 And let's count how many columns and rows we have. 00:38.440 --> 00:41.880 So 369 is nine columns. 00:41.880 --> 00:47.960 So I'm going to put nine columns not nine column exactly nine 1011. 00:47.960 --> 00:50.680 So we're going to put 11 columns and one row. 00:50.720 --> 00:52.920 After doing that let's click on this slice. 00:52.920 --> 00:55.560 And then let's click on this apply button. 00:55.560 --> 00:56.440 And now it's fine. 00:56.440 --> 00:59.160 So I'm going to select my game view once again here. 00:59.640 --> 01:03.360 And let's click on this arrow by now and I'm going to choose the first one. 01:03.360 --> 01:05.000 So let's select that. 01:05.000 --> 01:09.000 And we're going to drag it over to this in view or in this hierarchy. 01:09.240 --> 01:11.360 So as soon as we drag it we can see. 01:11.400 --> 01:14.640 But the problem is that is it is too much small. 01:14.640 --> 01:17.040 So we need to make it bigger in size. 01:17.040 --> 01:19.600 So I'm going to select our sprite sheet one more time. 01:19.600 --> 01:23.360 And let's make this sprite uh per unit something around 16. 01:23.360 --> 01:24.960 And let's click on this apply. 01:25.080 --> 01:29.480 And now we are able to see if you just want to make it a little bit bigger. 01:29.480 --> 01:33.880 Then you can just make this a pixel per unit even smaller number. 01:33.880 --> 01:38.320 So I'm going to choose something like uh 12 to make it a little bit bigger. 01:38.320 --> 01:39.800 Let's click on this apply. 01:40.000 --> 01:41.800 Now we can see it seems fine. 01:42.040 --> 01:46.720 So we're going to do the same thing as we created this heart uh heart game object. 01:46.720 --> 01:49.160 Basically we're going to have two animation. 01:49.280 --> 01:53.520 Uh, first will be this coin spinning which will spin around itself. 01:53.520 --> 01:56.560 And the second, uh, animation just going to be the collected one. 01:56.560 --> 01:59.950 Basically it will go up and over time it's going to fade out. 01:59.990 --> 02:04.510 Basically, we're going to do the same thing as we have done in this hard game object. 02:04.510 --> 02:09.630 So let's create an empty parent game object first because we're going to have to animation clip and 02:09.630 --> 02:10.510 the collected one. 02:10.510 --> 02:11.350 So that's why. 02:11.470 --> 02:12.670 So let's go to hierarchy. 02:12.670 --> 02:14.710 Let's right click or hit this plus icon. 02:14.710 --> 02:16.550 Let's create an empty game object. 02:16.550 --> 02:19.550 And I'm going to call this game object to something like coin. 02:19.950 --> 02:25.510 And and I'm going to select this uh tool move tool from this in view. 02:25.630 --> 02:32.790 And I'm going to choose an gizmos for that something this or this we can choose I'm going to choose 02:32.790 --> 02:33.470 this one. 02:33.790 --> 02:37.910 And I'm going to drag it top up in my hierarchy so I can see all the time. 02:37.910 --> 02:40.670 And now I'm going to select my this coin sprite. 02:40.830 --> 02:42.710 So let's select this coin sprite. 02:42.710 --> 02:48.710 And firstly I'm going to name it to something like coin sprite a coin sprite. 02:48.950 --> 02:55.590 And let's select this coin sprite in the hierarchy and drag it over to this coin game object in hierarchy. 02:55.750 --> 02:59.270 And we're going to go over to transform of this coin sprite. 02:59.310 --> 03:01.070 Let's right click there and reset. 03:01.070 --> 03:07.390 So it's going to reset the position as the position of our coin game object or the parent one as you 03:07.390 --> 03:08.110 can see. 03:08.110 --> 03:09.790 So let's add some component. 03:09.790 --> 03:14.110 So first thing we're going to add a rigid body 2D for a gravity. 03:14.110 --> 03:16.310 And we're going to set the gravity equal to zero. 03:16.310 --> 03:19.630 So it's not going to fall down due to our gravity. 03:19.630 --> 03:21.910 So let's select the coin parent one. 03:21.910 --> 03:24.190 So the select the parent one not the child. 03:24.390 --> 03:25.230 Select the parent. 03:25.230 --> 03:27.270 Go over to uh go over to Inspector. 03:27.270 --> 03:28.710 Click on Add Component. 03:28.710 --> 03:32.230 And we're going to add a rigid body 2D component. 03:32.510 --> 03:35.590 And let's set the gravity body type to kinematic. 03:35.590 --> 03:38.470 So it's not going to fall down due to gravity. 03:38.630 --> 03:44.150 And we're going to choose collision detection to continuous and interpolate to interpolate to just making 03:44.190 --> 03:44.870 out smooth. 03:44.910 --> 03:47.670 Or you can just leave it to none as well. 03:47.670 --> 03:49.230 This interpolate section. 03:49.230 --> 03:51.070 But I'm going to choose interpolate. 03:51.190 --> 03:57.620 And let's add one more component which will be the collider 2D for collision detection. 03:57.620 --> 04:03.300 So let's click on Add Component and I'm gonna add a box Collider 2D to just fit it perfectly. 04:03.300 --> 04:09.220 And let's click on this Edit Collider to edit the collider as the size of our coin sprite. 04:09.820 --> 04:12.780 And we can see this is fine by now. 04:13.060 --> 04:18.940 And make sure you just go to trigger and check this one underneath your box Collider 2D component. 04:18.940 --> 04:21.780 And now we are ready to create our animation. 04:21.780 --> 04:26.420 But before we create, let's assign this coin game object as a coin tag. 04:26.420 --> 04:27.540 So let's go to Inspector. 04:27.540 --> 04:29.700 Let's click on this untag add tag. 04:29.700 --> 04:33.500 And then we're going to click on this plus icon in order to add a tag. 04:33.700 --> 04:36.380 And we're going to create a coin tag something like that. 04:36.380 --> 04:37.380 And save it. 04:37.380 --> 04:43.340 And make sure you just go over to that GameObject once again and assign it the tag which you recently. 04:43.340 --> 04:44.500 So name it. 04:44.500 --> 04:48.020 So I assign it the coin game object as a coin tag. 04:48.060 --> 04:52.700 As you can see in Inspector, and we are ready to create our animation. 04:52.700 --> 04:56.740 To create the animation we're going to select the tile game object, not the parent. 04:56.740 --> 04:58.260 So we're going to select our child. 04:58.500 --> 05:03.060 And let's go to project tab sprites and then UI folder. 05:03.060 --> 05:06.500 Basically move over to that folder where you have the sprites. 05:06.500 --> 05:08.060 So I'm going to select all of these. 05:08.060 --> 05:09.620 So let's click on this arrow. 05:09.620 --> 05:13.740 And I'm going to select all of this coin sprite by holding down shift shift. 05:14.020 --> 05:16.380 Basically this coin individual sprites. 05:16.380 --> 05:22.420 And I'm going to drag it over to this coin sprite GameObject in the hierarchy in order to make the animation 05:22.420 --> 05:23.180 right away. 05:23.180 --> 05:25.900 And it's making our animation right away. 05:25.900 --> 05:31.700 Instead of instead of moving over to this animation tab and then click on that create button in order 05:31.700 --> 05:33.140 to create the animation. 05:33.140 --> 05:34.980 And this is pretty much first way. 05:34.980 --> 05:40.340 So you can just select all of the individual sprite, and then you can just drag it over to top of that 05:40.340 --> 05:44.900 game object in the hierarchy in order to make the animation even faster way. 05:44.900 --> 05:47.220 So I'm going to move over to my assets folder. 05:47.220 --> 05:52.500 In assets folder I have created this animation folder, so I'm going to open that up as well as I'm 05:52.500 --> 05:54.740 going to open up this stop animation. 05:54.740 --> 05:59.140 And I'm going to create a separate subfolder for my coin animation. 05:59.140 --> 06:01.540 So let's right click the new folder. 06:01.540 --> 06:05.540 And I'm going to name this folder to Coin Underscore Animation. 06:06.060 --> 06:10.540 And let's open up this subfolder as well by double clicking on it. 06:10.540 --> 06:12.380 And we have to name the animation. 06:12.380 --> 06:15.860 So this one is just going to be the spinning one coin coin spinning. 06:15.860 --> 06:20.460 So I'm going to call it coin underscore spinning spinning. 06:20.820 --> 06:21.700 And that's fine. 06:21.700 --> 06:23.500 And let's click on the save button. 06:23.660 --> 06:26.580 And it's it's going to create the animation right away. 06:26.580 --> 06:32.180 So now if we select our coin sprite in the hierarchy move over to animation tab and then click on this 06:32.180 --> 06:32.940 plus icon. 06:32.940 --> 06:36.700 We can see indeed the coin just spinning around itself. 06:36.700 --> 06:38.540 And this seems pretty much cool. 06:39.020 --> 06:42.620 And we're going to have another animation which will be the collected one. 06:42.620 --> 06:47.220 Basically this coin will go up and over time it's gonna fade out. 06:47.220 --> 06:48.980 So let's create that animation. 06:48.980 --> 06:51.700 So we're going to select our coin sprite in the hierarchy. 06:51.740 --> 06:53.140 Let's go to animation tab. 06:53.140 --> 06:56.450 Click over here and we're going to click on this Create New clip. 06:56.450 --> 07:00.130 And this is going to be the coin underscore uh the collected one. 07:00.130 --> 07:04.650 So I'm going to call it collected or collide one. 07:04.650 --> 07:09.210 So let's uh I'm going to call it collected instead collected. 07:09.210 --> 07:11.210 And let's click on the save button. 07:11.410 --> 07:13.370 And we need to make the animation. 07:13.370 --> 07:16.810 So let's click on this red button in order to record the animation. 07:16.810 --> 07:19.810 And I'm going to move over to 60 frames or one second. 07:20.010 --> 07:23.810 And I'm going to select my coin Sprite GameObject in the hierarchy. 07:23.810 --> 07:26.050 And let's move it up direction. 07:26.050 --> 07:30.090 And then over time we're gonna, uh, we're gonna make it fade out. 07:30.090 --> 07:35.930 So let's select the coin sprite, let's go to sprite Renderer component and a color. 07:35.930 --> 07:37.010 Let's click there. 07:37.010 --> 07:39.290 And in the bottom A which is 255. 07:39.290 --> 07:41.570 So I'm going to make it all the way to the zero. 07:41.690 --> 07:46.090 So once we make it zero we can see the coin just gets invisible. 07:46.090 --> 07:51.570 So we can just click on this play button in order to uh see the animation. 07:51.570 --> 07:55.370 So it's just going up and over time is just fading out. 07:55.410 --> 07:56.490 As you can see. 07:56.730 --> 08:01.010 And once you're done, you can just click on this red button to capture the animation. 08:01.010 --> 08:02.890 Or you can just leave it like that. 08:02.930 --> 08:05.490 It's automatically gonna capture the animation. 08:05.490 --> 08:11.010 So now if we select our coin sprite GameObject in the hierarchy, move over to animator tab. 08:11.010 --> 08:17.090 We can see we have animation where we have coin spinning as well as the coin collected. 08:17.090 --> 08:21.050 So we also need to make transition between these animation state. 08:21.050 --> 08:24.410 So let's right click on this coin animation spinning. 08:24.410 --> 08:26.810 And we're going to make transition to coin collect it. 08:26.810 --> 08:28.210 And let's select this transition. 08:28.210 --> 08:30.330 Go over to Inspector and we're going to untick. 08:30.330 --> 08:34.850 This has exit time as well as we're going to set the transition duration to zero. 08:34.850 --> 08:39.610 And we need to choose a condition in which condition we want to play the animation clip. 08:39.610 --> 08:42.690 So let's go to animator tab and let's select this parameter. 08:42.690 --> 08:44.250 Let's click on this plus icon. 08:44.250 --> 08:46.570 And we're going to choose a trigger in the bottom. 08:46.570 --> 08:52.250 And I'm going to call this trigger to something like collide as I have done in my hard game object. 08:52.280 --> 08:55.280 So basically we're just approaching the same way. 08:55.720 --> 08:57.520 And now I'm going to choose this color. 08:57.520 --> 09:00.960 So let's click on this plus icon in the condition Inspector. 09:01.280 --> 09:07.720 And now if we just click on this play button and manually just gonna manually try to trigger this collide 09:07.720 --> 09:08.440 parameter. 09:08.440 --> 09:10.600 You will see the coin collected animation. 09:10.600 --> 09:17.200 Just gonna play right away of this coin sprite as soon as we just trigger it manually. 09:17.200 --> 09:23.200 So if I just trigger, as you can see, as soon as we trigger it's just going up and over time it's 09:23.200 --> 09:23.960 just fading out. 09:23.960 --> 09:26.840 But the problem is that this animation is just looping. 09:26.840 --> 09:29.720 Basically it's just playing over again and again. 09:29.720 --> 09:31.320 So we want to stop that. 09:31.320 --> 09:35.320 So let's get out of play mode and we're going to move over to my project tab. 09:35.320 --> 09:40.680 Then assets then animation basically where we created or just place those animation clips. 09:40.680 --> 09:42.560 So we're going to move over to that folder. 09:42.560 --> 09:45.160 So I have this coin underscore animation. 09:45.160 --> 09:47.800 And we can see we have both of this animation clip. 09:47.800 --> 09:50.840 We have coin spinning as well as the coin collected. 09:50.840 --> 09:56.800 So I'm going to choose my coin collected and I'm going to uncheck this loop time in the in the inspector. 09:56.800 --> 09:59.280 So the animation clip will not loop. 09:59.840 --> 10:00.960 So now it's fine. 10:00.960 --> 10:06.240 And we need to make this coin a sprite coin GameObject in our hierarchy a prefab. 10:06.240 --> 10:07.560 So we're going to have the copy. 10:07.720 --> 10:10.480 So let's select the coin GameObject in the hierarchy. 10:10.480 --> 10:14.600 And let's drag it over to this prefabs folder in order to make it prefab. 10:14.640 --> 10:20.560 Now we just made it prefab as you can see, and we are ready to collect that one. 10:21.040 --> 10:27.640 Uh, so we just created and so we also need to uh, collect this coin, uh GameObject. 10:27.640 --> 10:28.680 So let's do that. 10:28.680 --> 10:31.400 So I'm going to select my player game object in the hierarchy. 10:31.520 --> 10:34.640 And let's open up the player script by double clicking on it. 10:35.160 --> 10:40.240 And what we're going to do we're going to use this same function one more time which is ontriggerenter. 10:40.240 --> 10:43.200 So this function get called when we trigger with something. 10:43.200 --> 10:48.040 And if we move to unity then our coin and then choose this coin sprite. 10:48.280 --> 10:51.760 Uh coin sprite coin game object, not the child one. 10:52.160 --> 10:54.360 Uh, and move over to Box Collider 2D. 10:54.400 --> 10:56.880 We can see we just check this box. 10:56.880 --> 11:04.040 So that's why we're going to use a ontriggerenter 2D function in order to, uh, check the trigger. 11:04.040 --> 11:07.640 And I'm going to move this coin sprite game object a little bit down. 11:07.640 --> 11:11.160 So this player game object easily can collect that one. 11:11.360 --> 11:14.440 So we assign it this coin game object as a coin tag. 11:14.440 --> 11:16.920 We can see in the inspector as well. 11:16.920 --> 11:18.080 So let's go to script. 11:18.080 --> 11:21.040 So this function get called when we trigger with something. 11:21.040 --> 11:24.760 And we can extract info by going over to this collision parameter. 11:24.760 --> 11:26.360 So I'm going to check it in the bottom. 11:26.360 --> 11:30.640 So I'm going to use this if condition and make first packet and some curly brackets. 11:30.640 --> 11:32.760 And what we want to check over here. 11:32.760 --> 11:35.360 We want to check whatever we triggered it with. 11:35.400 --> 11:37.840 If that game object has a tag called coin. 11:37.840 --> 11:42.960 So let's suppose if we trigger with this coin game object or collide with this coin game object, and 11:42.960 --> 11:47.600 we know we assigned this coin as a coin tag in the inspector, as you can see. 11:47.600 --> 11:49.910 So what we need to do in that situation? 11:49.910 --> 11:54.790 We need to collect this coin game object as well as we need to increase our coin. 11:54.790 --> 11:55.910 So let's go to Skip. 11:55.910 --> 11:59.230 And over here in this brackets we're going to check. 11:59.230 --> 12:01.590 So we're going to type collision dot game object. 12:01.590 --> 12:06.870 So basically we're just taking this parameter collision parameter in order to check and collision dot 12:06.870 --> 12:11.590 game object over here simply referencing the game object we triggered it with. 12:11.590 --> 12:15.030 So we definitely gonna trigger with that uh, coin game object. 12:15.030 --> 12:19.750 So collision dot game object over here is just going to be the coin game object. 12:19.750 --> 12:23.550 And then what we're going to do, we're going to extract the tag of the game object. 12:23.550 --> 12:25.590 So we're going to use this dot tag. 12:25.630 --> 12:27.950 And we're going to check if the tag is equals. 12:27.950 --> 12:34.390 Equals to coin means if we trigger with this coin game object and we do know we assign this coin as 12:34.390 --> 12:36.790 a coin tag means we just collecting that. 12:36.790 --> 12:41.510 So in that situation what we need to do and we're just doing it over here as you can see. 12:41.510 --> 12:47.110 So whatever we trigger it with if that game object has a tag called coin and we're checking it over 12:47.110 --> 12:48.790 here, as you can see. 12:48.790 --> 12:54.910 So if Collision's GameObject or tag if it's equals equals to coin means we just trigger it with that 12:54.910 --> 12:55.350 coin. 12:55.350 --> 12:59.510 So in that situation, what we need to do we need to increase our current coin. 12:59.510 --> 13:01.390 So let's go to top of our class. 13:01.390 --> 13:07.030 And let's create a variable to just keep track of how many coins we collected so far. 13:07.150 --> 13:11.270 And I'm going to do it somewhere in the bottom over here. 13:11.270 --> 13:15.390 And it doesn't need to be public so we can make it instead private. 13:15.390 --> 13:16.790 So I'm going to make it private. 13:16.830 --> 13:20.270 That will be int like whole number 01234. 13:20.430 --> 13:24.510 And I'm going to call this one to current coin current coin. 13:24.990 --> 13:27.510 And let's close that up with semicolon. 13:27.510 --> 13:30.430 So we just created this parameter which is current coin. 13:30.430 --> 13:34.150 In order to keep track of how many coins we collected so far. 13:34.390 --> 13:37.150 And I'm going to move over to this start function. 13:37.150 --> 13:39.710 So start function get call in the start of the game. 13:39.710 --> 13:42.310 So in the start of the game I have what I want to do. 13:42.350 --> 13:45.310 I'm going to set current coin equal to zero. 13:45.350 --> 13:46.590 Why we set it to zero. 13:46.590 --> 13:50.870 Because as soon as we're going to start our game, we're going to have zero coin. 13:50.910 --> 13:55.230 So that's why in the start of the game, I'm just setting current coin equal to zero. 13:55.270 --> 13:56.430 As you can see. 13:56.470 --> 13:58.950 And let's go to that line of code where we're triggering. 13:58.950 --> 14:00.550 So we're triggering over here. 14:00.550 --> 14:01.390 So what are we going to do. 14:01.390 --> 14:04.710 We're going to add current coin plus equal one. 14:04.750 --> 14:10.470 Or what you can simply do you can use this plus plus it also basically the same thing. 14:10.670 --> 14:13.750 So the current coin in the start of the game we have zero. 14:13.750 --> 14:17.550 And if we collide with that coin so what we're doing we just adding one. 14:17.550 --> 14:20.790 So this current coin is zero zero plus one. 14:20.790 --> 14:23.630 Or this plus plus basically means we're just adding one. 14:23.630 --> 14:26.110 So zero plus one is just going to be one. 14:26.110 --> 14:29.590 And if we collect the second coin so the current coin is now one. 14:29.590 --> 14:35.830 So one plus one is going to be two means we will increase our current coin once we trigger with that 14:35.830 --> 14:37.070 coin game object. 14:37.230 --> 14:42.390 And what we also need to do, we need to play the animation clip of that coin collected. 14:42.390 --> 14:47.980 So let's suppose we just collide with this coin game object means instead of playing the spinning of 14:47.980 --> 14:52.180 this coin right now, we need to play the collected, collected. 14:52.180 --> 14:56.540 And we can see we have in this coin sprite the animator component. 14:56.540 --> 15:02.620 So once we created this animation clip, this coin spinning, as well as the coin collected and animator 15:02.620 --> 15:04.980 component just added to this coin sprite. 15:04.980 --> 15:08.980 So basically what we have to do, we need to move over to parent GameObject first. 15:08.980 --> 15:14.740 So in our case coin and by that we can access this coin sprite child game object. 15:14.740 --> 15:17.500 And then we're going to move over to this animator component. 15:17.500 --> 15:20.060 And then we're going to trigger this collide parameter. 15:20.060 --> 15:25.900 And we do know once we're gonna trigger it's going to play the coin collected animation clip right away. 15:25.900 --> 15:32.100 So basically that is the thing we have done the same thing or we just doing in a same way as we have 15:32.100 --> 15:35.140 done already in our hard game object. 15:35.140 --> 15:36.260 So let's do that. 15:36.260 --> 15:41.380 So after increasing our current coin we're gonna play the collected animation clip. 15:41.380 --> 15:46.140 So we're gonna use this collision game object and collision game object over here. 15:46.180 --> 15:48.020 This is gonna be the coin game object. 15:48.020 --> 15:51.380 And then we're gonna move over to Coin game Object Transform component. 15:51.380 --> 15:53.820 And then we're going to use this dot get cell. 15:53.860 --> 15:55.260 And we're going to get the child. 15:55.300 --> 15:58.860 So the we're looking for is a file child or the coin sprite. 15:58.860 --> 16:03.260 So that's why we're going to put zero zero basically means the referencing the first child. 16:03.260 --> 16:06.540 And we have only one child in that coin game object. 16:06.540 --> 16:10.260 So the get child over here zero is gonna be the coin sprite. 16:10.260 --> 16:13.420 So basically we're just going over to that coin sprite game object. 16:13.420 --> 16:15.580 And now we're going to get the animator component. 16:15.580 --> 16:17.860 So we're going to use this Getcomponent function. 16:18.140 --> 16:22.500 Sorry Getcomponent as syntax or this get component. 16:22.940 --> 16:28.580 And in this arrows we need to pass the component name that we really looking for. 16:28.580 --> 16:32.620 So in our case we just need to get the animator component. 16:32.620 --> 16:38.100 So in arrows we're going to pass this animator component and then make first bracket and then dot. 16:38.100 --> 16:43.060 We're going to use this set trigger function in order to trigger that parameter and make first bracket. 16:43.060 --> 16:44.930 Then close that off with Semicolon. 16:44.930 --> 16:49.650 So in this bracket you need to pass the parameter name in quotation. 16:49.650 --> 16:52.370 And the parameter name we're going to pass it called light. 16:52.370 --> 16:57.370 We can see in the inspector sorry we can see in our animator tab which is collide. 16:57.370 --> 17:01.450 So basically what we're doing we're just going over to this coin game object. 17:01.450 --> 17:05.890 And then we're just moving over to this transform component of this coin game object. 17:05.890 --> 17:11.730 And by this transform component which is moving over to this coin sprite game object, as you can see 17:11.730 --> 17:13.810 over here, a coin sprite. 17:13.810 --> 17:17.250 And then after that we're just going over to animator component. 17:17.250 --> 17:23.050 So when we uh moved moved over to this coin sprite, then we're just taking this animator component 17:23.050 --> 17:25.890 as you can see, which is Getcomponent animator. 17:25.890 --> 17:31.010 And then we just, uh, using this trigger function in order to trigger the parameter. 17:31.010 --> 17:33.730 So basically we're just triggering this collide parameter. 17:33.730 --> 17:39.050 And we do know once we trigger this parameter it's going to play the coin collected animation clip right 17:39.050 --> 17:39.450 away. 17:39.650 --> 17:44.690 Uh so we're just triggering the collide parameter as you can see in our code. 17:44.730 --> 17:47.970 Now we're going to press down Ctrl S in order to save our script. 17:47.970 --> 17:49.890 And now let's move over to unity. 17:51.810 --> 17:57.570 So basically we're just moving over to this coin sprite game object and then moving over to this animator 17:57.570 --> 17:58.210 component. 17:58.210 --> 18:04.210 And by this animator component of this coin sprite, we're just getting this collide parameter add. 18:04.250 --> 18:09.650 And we do know once we trigger it's going to play the coin collected animation clip right away. 18:09.650 --> 18:11.250 So let's have a look on this. 18:11.810 --> 18:14.530 And I'm going to click on this play button in the top. 18:14.650 --> 18:21.370 And if I select my player game object uh we can not able to see our current coin because we just made 18:21.370 --> 18:22.290 it private. 18:22.410 --> 18:25.610 Uh, that current coin parameter as a private field. 18:25.610 --> 18:28.770 So let's suppose you still want to see that private field. 18:28.770 --> 18:34.210 So what you need to do in that situation go over to inspector in the top right Inspector you can see 18:34.250 --> 18:34.730 three dots. 18:34.730 --> 18:37.970 So just click there and then click click on this debug. 18:38.010 --> 18:44.090 And as soon as we have chosen debug we can see underneath our player skip in the bottom current coin 18:44.090 --> 18:45.530 and it's set to zero. 18:45.530 --> 18:47.930 So let's click on this play button in the top. 18:48.090 --> 18:54.450 And once we collect this coin game object you will see this current coin just going to increase by one. 18:54.450 --> 18:56.210 So let's have a look on this. 18:56.210 --> 19:01.530 So just take a moment to give it give it a moment to just play that. 19:02.050 --> 19:04.170 So I'm gonna trigger with this coin. 19:04.850 --> 19:07.410 And as soon as we trigger it or collide it. 19:07.410 --> 19:10.770 So I'm going to click on this pause button in the top to pause my game. 19:10.770 --> 19:15.090 And if we move over to player skip we can see current coin is now one. 19:15.090 --> 19:19.770 And as soon as we trigger it, it just plays the coin collected animation clip. 19:19.770 --> 19:24.530 And basically it's just going up and over time it's just fading out. 19:24.850 --> 19:28.010 Uh, so that basically it's just playing perfectly. 19:28.010 --> 19:33.970 But the problem is that if we move over to a hierarchy, we can see the coin game object still laying 19:34.010 --> 19:38.010 around in the hierarchy as well as in the scene view we can see. 19:38.010 --> 19:41.330 So after one second, what we need to do, we need to destroy this. 19:41.400 --> 19:41.800 Why? 19:41.840 --> 19:45.880 Because after one second, we're just completing the whole animation clip. 19:45.880 --> 19:52.080 So after one second, we also need to destroy this coin GameObject, because we collected that one and 19:52.080 --> 19:55.240 we increased our current coin by one unit. 19:55.240 --> 20:00.280 So let's get out of play mode and I'm gonna move over to my inspector mode one more time. 20:00.280 --> 20:02.560 So just go over to top right three dot. 20:02.600 --> 20:08.160 So just click there and then click on this normal in order to go back in normal mode. 20:08.160 --> 20:14.920 So if we select our coin sprite in the hierarchy move over to animation tab and then choose this coin 20:14.920 --> 20:15.560 collected. 20:15.600 --> 20:22.600 We can see after one second the collected animation clip is playing are playing perfectly. 20:22.600 --> 20:22.920 So. 20:22.920 --> 20:28.200 So after one second it's just a fading or it's get totally invisible. 20:28.200 --> 20:33.120 So after this amount of time, we also need to delete the coin game object or the child. 20:33.120 --> 20:39.840 So if we select if we delete or destroy this coin GameObject, other child will also be destroyed with 20:39.880 --> 20:44.520 it because the coin sprite is the child of our coin game object, so that's why. 20:44.560 --> 20:45.760 So let's go to school. 20:45.960 --> 20:47.120 So let's go to script. 20:47.120 --> 20:51.080 So after triggering that parameter we're going to use this destroy function. 20:51.080 --> 20:53.760 And we do not destroy function as a first argument. 20:53.760 --> 20:56.360 It's going to take the game object you want to destroy. 20:56.360 --> 20:59.600 So in our case we're going to pass this collision game object. 20:59.600 --> 21:03.160 It basically means the game the game object we triggered it with. 21:03.160 --> 21:06.040 So we definitely gonna trigger with that coin game object. 21:06.040 --> 21:09.760 So collision game object means over here the coin game object. 21:09.760 --> 21:12.640 And the second thing we're going to specify the time. 21:12.640 --> 21:13.920 So we're going to put one f. 21:13.920 --> 21:18.680 And we do know after one f or once again it's just completing the whole animation clip. 21:18.680 --> 21:22.880 So that's why as a second parameter we just specified our time. 21:22.880 --> 21:24.760 And we're going to close that off with semicolon. 21:24.760 --> 21:27.880 And let's save our script and let's move to unity. 21:27.880 --> 21:34.240 So after one second you will see this coin game object will also be destroyed from the hierarchy as 21:34.240 --> 21:35.640 well as the scene view. 21:35.640 --> 21:41.510 Because we destroying after one second as a second parameter we just specified our time. 21:41.750 --> 21:45.750 So let's click on this play button in the top and have a look on this. 21:51.310 --> 21:53.070 So just wait for to compile. 21:54.990 --> 21:57.710 And let's try to collect this coin game object. 21:57.710 --> 21:59.110 And you will see that. 22:00.190 --> 22:02.790 So as you can see it's played collected. 22:02.790 --> 22:09.990 And if I just pause my game and move over to hierarchy, we cannot see able to see the coin game object 22:09.990 --> 22:14.110 at all in this hierarchy as well as in the scene view. 22:14.150 --> 22:20.150 As you can see, means after once again playing the whole animation clip, which is the collected one, 22:20.190 --> 22:23.150 it just gets destroyed after playing that. 22:23.350 --> 22:24.630 So I hope you get the idea. 22:24.630 --> 22:26.270 So I'm gonna get out of play mode. 22:26.270 --> 22:28.030 And basically that is the thing. 22:28.030 --> 22:33.590 So make sure you just make your coin game object as well a prefab so you can have because we're gonna 22:33.590 --> 22:36.030 place this coin in our ground tiles. 22:36.350 --> 22:39.750 We're gonna have multiple coins in order to collect them.
