WEBVTT 00:00.040 --> 00:02.240 We're going to clean up our code. 00:02.240 --> 00:03.120 So let's do that. 00:03.120 --> 00:05.600 Firstly let's go with this player script. 00:05.600 --> 00:08.200 So I'm going to select my player GameObject in the hierarchy. 00:08.200 --> 00:11.400 And let's open up the player script by double clicking on it. 00:11.400 --> 00:16.760 So instead of using find any object by type we're going to use a singleton pattern. 00:16.760 --> 00:19.960 So basically what we're going to do we're going to go to the top of our class. 00:19.960 --> 00:22.640 And over here we're going to create a variable. 00:22.640 --> 00:24.000 So we're going to make it public. 00:24.000 --> 00:29.840 So we can easily access through any other class or any other script. 00:29.840 --> 00:31.840 And we're going to create a static. 00:31.840 --> 00:36.680 Static basically means that we can simply type the this player class name. 00:36.680 --> 00:40.960 And then we can access any variable that we would like to access. 00:40.960 --> 00:42.720 We can access this dumb height. 00:42.760 --> 00:48.840 We can access this speed through another script or another C sharp class that by directly typing this 00:48.840 --> 00:54.320 player script name and that that is the reason we just using this static. 00:54.320 --> 01:00.320 And we're going to create a variable as the name of our this player script or this player class. 01:00.320 --> 01:06.790 So we're going gonna create a variable, uh, and as the name of our, uh, C class, which is player. 01:06.790 --> 01:11.590 So we're going to create a player and we can call simply this one something like instance. 01:11.590 --> 01:14.670 So we're going to call it instance uh instance. 01:14.670 --> 01:17.030 And we're going to close that up with semicolon. 01:17.030 --> 01:19.710 And we will use this awake function. 01:19.710 --> 01:22.350 So we're going to use this private void awake. 01:22.470 --> 01:28.270 So make sure you just include as I did over here basically this function get call right before this 01:28.270 --> 01:29.230 start function. 01:29.230 --> 01:32.030 And it's basically calls as like a start function. 01:32.030 --> 01:35.590 But it get call right before this start function. 01:35.590 --> 01:37.550 And it just get call one time. 01:37.550 --> 01:43.070 So in this start of the game what we want to check, we want to check if the instance is single or not. 01:43.270 --> 01:49.670 If basically we just want a one player strip in our sample scene or in this game. 01:49.830 --> 01:52.190 So we only want one player skip. 01:52.190 --> 01:55.550 And we don't want to have multiple player skip. 01:55.550 --> 01:56.750 So it's gonna be error. 01:56.750 --> 01:57.630 So that's why. 01:57.710 --> 02:00.190 So we're going to create an instance. 02:00.190 --> 02:00.230 Instant. 02:00.710 --> 02:06.590 So we just created this public static player instant and we will move over to this awake function. 02:06.830 --> 02:11.990 So in the awake function we're going to set instant equal to this. 02:11.990 --> 02:14.470 So we just storing all of the information. 02:14.470 --> 02:17.910 Basically this update function this update function. 02:17.910 --> 02:22.550 Then this should function of this player class into this instance parameter. 02:22.590 --> 02:26.110 As you can see we just set instant equal to this. 02:26.110 --> 02:32.510 So we're storing all of the information about this player class into this instant parameter. 02:32.670 --> 02:37.270 And by now we can extract information by going over to this player script. 02:37.270 --> 02:38.270 And then instant. 02:38.270 --> 02:42.070 And we can extract anything that we would like to extract. 02:42.070 --> 02:46.270 Something like we can extract this health text as well from another class. 02:46.270 --> 02:52.790 If we want this rigid body and anything that uh, anything like that, this start function as well, 02:52.830 --> 02:58.670 as well as any custom function that we have in this player, skip, we can easily access. 02:58.710 --> 03:01.380 But before we set instant equal to this. 03:01.420 --> 03:04.700 We need to check if the script is a one time or not. 03:04.700 --> 03:11.180 Basically, we only want to have one player script in this whole game or in this level one, you can 03:11.180 --> 03:14.100 simply say so we only want one script. 03:14.100 --> 03:17.460 So before we set instant equal to this, we're going to check. 03:17.500 --> 03:24.340 If so, we will check if instant instant is equals equals to null if that is the case. 03:24.340 --> 03:26.380 So we're going to make some curly brackets. 03:26.380 --> 03:33.300 So if instant equal to minus the null then we're going to basically we're going to cut this one which 03:33.300 --> 03:34.700 is instant equal to this. 03:34.700 --> 03:38.700 And we're going to paste inside of this curly brackets. 03:38.700 --> 03:42.020 So we're checking if instance equals equals to null. 03:42.060 --> 03:43.900 Basically means this player script. 03:44.260 --> 03:46.260 Uh this player script is empty. 03:46.260 --> 03:50.340 Basically we don't have any player skip or this player game object. 03:50.340 --> 03:55.260 You can simply say or win in which game object the script is attached. 03:55.580 --> 03:59.860 So in our case the player skip attached to this player game object. 03:59.900 --> 04:03.100 So we're checking if instance equals equals to null. 04:03.140 --> 04:06.100 Mean we don't have any player script. 04:06.100 --> 04:09.220 Then what we're doing we're just setting instance equal to this. 04:09.220 --> 04:16.060 So in that situation we're just storing all of the information about this C-sharp player class into 04:16.060 --> 04:17.660 this instance parameter. 04:17.780 --> 04:25.460 And we can extract info by going over to this instance instance parameter instead of using that which 04:25.460 --> 04:29.340 is fairly taxing, like find or any object by type. 04:29.340 --> 04:31.820 And then you have to pass the script name. 04:31.820 --> 04:36.860 So we can simply just go move over to this player script and then instance. 04:36.860 --> 04:41.980 And we can extract any function or any variable that we're looking for directly. 04:41.980 --> 04:45.740 So that's why we just created public static player instance. 04:45.740 --> 04:48.660 And let's suppose we already have a call player script. 04:48.660 --> 04:54.820 So in that situation what we need to do we need to delete or we need to destroy this instance. 04:54.820 --> 04:56.020 Then we don't want. 04:56.060 --> 04:59.540 So we're going to else else we already have a instance. 04:59.540 --> 05:04.450 Then we're going to destroy the instant or this player class that we're storing information. 05:04.450 --> 05:06.530 We're going to destroy it right away. 05:06.530 --> 05:08.330 So we're going to use this destroy function. 05:08.330 --> 05:09.650 In order to do that. 05:09.650 --> 05:12.810 And in this brackets you need to pass the game object. 05:12.810 --> 05:14.370 So we're going to pass itself. 05:14.370 --> 05:20.170 So with the script this player's script is attached to our player game object. 05:20.170 --> 05:23.290 So the player game object just referencing itself. 05:23.290 --> 05:24.450 So we're just destroying. 05:24.490 --> 05:27.010 And we're going to close that up with semicolon by now. 05:27.010 --> 05:30.650 And then we're going to press down Ctrl S in order to save our script. 05:30.770 --> 05:37.090 So we're just storing basically we just created a variable as the name of our player skip as you can 05:37.090 --> 05:37.570 see. 05:37.570 --> 05:43.330 So and we're storing all of the information about this player class or this player script into this 05:43.370 --> 05:44.890 instance parameter. 05:44.930 --> 05:49.890 As you can see if the instance is equals equals to null basically means empty. 05:50.050 --> 05:52.610 Then we're just setting instance equal to this. 05:52.610 --> 06:00.210 Basically storing all all of the things in this in this instance parameter or this instance parable. 06:00.250 --> 06:03.290 Now we're going to move over to player sorry unity. 06:03.290 --> 06:10.930 And we're going to access the player script or anything that we extracting from this player game object. 06:10.930 --> 06:16.210 So basically this enemy game object we do know it's going to keep track of where player is. 06:16.250 --> 06:18.490 And we're just going over to this player script. 06:18.490 --> 06:22.570 And then we just extracting information about this player game object. 06:22.570 --> 06:25.770 So what we're going to do over here, we're going to move. 06:25.890 --> 06:30.930 We're gonna open up the enemy tool script as well as enemy one script in order to do that. 06:30.930 --> 06:34.050 So we're going to select our enemy to GameObject in the hierarchy. 06:34.050 --> 06:37.970 And let's open up the enemy two script quickly by double clicking on it. 06:37.970 --> 06:44.770 And over here as you can see we're checking if call info then game object dot get component. 06:44.770 --> 06:48.370 And the component we're looking for is not equal to null. 06:48.410 --> 06:51.890 Then what we're doing we're just going over to that player game object. 06:51.890 --> 06:53.650 Basically this player game object. 06:53.650 --> 06:58.250 And then we just going over to this player script of this player game object. 06:58.250 --> 07:01.680 And there we're just calling the function, which is the take damage. 07:01.680 --> 07:04.840 And we do know what we have done inside that function. 07:04.840 --> 07:10.560 So instead of using this long term like this, we're going to simply go to that player skip. 07:10.560 --> 07:13.800 So what we're going to do we're going to go over to that player skip. 07:13.840 --> 07:15.920 So we can simply pass the script name. 07:15.920 --> 07:17.520 So in our case player. 07:17.520 --> 07:20.920 And then we're going to use this dot and we're going to access the instance. 07:20.920 --> 07:27.440 And we do know we just created the instance parameter right there as you seen in our player skip or 07:27.480 --> 07:29.120 that player C class. 07:29.120 --> 07:32.040 And then from there by this instance parameter. 07:32.040 --> 07:33.600 Now we're going to call the function. 07:33.600 --> 07:36.520 And the function we're looking for is a take damage. 07:36.520 --> 07:38.440 So we're going to type this take damage. 07:38.440 --> 07:40.080 And we're going to make first bracket. 07:40.080 --> 07:42.400 And in argument I'm going to pass one. 07:42.400 --> 07:44.480 And let's close that up with semicolon. 07:44.480 --> 07:48.560 So as you can see this seems too much clean by now. 07:48.880 --> 07:55.520 But instead of using this call info that dot GameObject, that dot get component, which is fairly taxing. 07:55.520 --> 07:59.920 So basically we're just going over to we just simply pass the player, script name. 07:59.920 --> 08:05.880 So in our case player as you can see, and then going over to that instance and then calling the Takedamage 08:05.880 --> 08:11.280 function, basically we just going over to this player script and then we're just going over to this 08:11.320 --> 08:12.560 instance parameter. 08:12.560 --> 08:19.000 And by this instance we're just calling this Takedamage function basically as we have done before. 08:19.200 --> 08:20.960 So we're just doing the same thing. 08:20.960 --> 08:27.080 But uh, by but uh, right now we're just using this instance parameter. 08:27.080 --> 08:32.360 So the uh creating singleton pattern makes our code a lot more clean. 08:32.360 --> 08:39.240 And if you haven't grabbed it, uh, perfectly, or if you just want to get it in more details, then 08:39.280 --> 08:46.040 of course I will also gonna give a another video link in the resources so you can check that out about 08:46.080 --> 08:49.120 a singleton pattern if you just want to learn it more. 08:49.240 --> 08:54.880 So we basically storing all of the information about this player class into this instance parameter. 08:54.880 --> 09:00.710 And then we're using this instance parameter in order to call the function, and we use this static. 09:00.710 --> 09:03.150 So we can simply pass the player screen name. 09:03.150 --> 09:09.030 So as you can see we have done over here, which is we just simply pass the player script name. 09:09.030 --> 09:11.110 Then we just moving over to instant. 09:11.110 --> 09:13.630 So make sure you just using that static. 09:13.670 --> 09:16.590 Else you're not gonna able to do like this. 09:16.590 --> 09:22.150 So so you can simply pass the script name without hesitating like that doing anything. 09:22.150 --> 09:27.870 So that's why we just created a static parameter which allow us to use shortly. 09:27.870 --> 09:33.630 Basically, we can just simply type the script name which the, the script that you looking for. 09:33.630 --> 09:37.230 And then you can just do that as I have done over here. 09:37.230 --> 09:40.550 So I'm going to press down Ctrl S in order to save my script. 09:40.550 --> 09:42.390 And now let's move over to unity. 09:42.710 --> 09:47.310 And we're going to do the same thing in my enemy one game object as well. 09:51.590 --> 09:53.270 So just wait for to compile. 09:54.150 --> 10:00.230 And now if I select my enemy one game object I'm going to do the same thing in this anime script, this 10:00.230 --> 10:01.990 anime one script as well. 10:01.990 --> 10:07.350 So I'm gonna open up my anime script by double clicking on it and let's go to the top of our class so 10:07.350 --> 10:09.030 we don't need to do that. 10:09.310 --> 10:11.230 Uh, let's create let's create that. 10:11.230 --> 10:17.390 But before we do, I'm gonna do it, uh, basically over here, as you can see, we're doing basically 10:17.390 --> 10:19.670 we damaging our player over here. 10:19.670 --> 10:24.150 So we're gonna move over to that player class, and then we're going to access the instant. 10:24.150 --> 10:27.230 And by this instant I'm going to call the Takedamage function. 10:27.230 --> 10:28.830 And let's make first bracket. 10:28.830 --> 10:31.150 And then we're going to close that up with semicolon. 10:31.150 --> 10:33.750 And also we need to pass the argument. 10:33.750 --> 10:38.470 So basically we're just going over to this player script and then going over to this instant. 10:38.470 --> 10:44.950 And by using this instant we also call it the Takedamage function in that enemy one script as well. 10:44.950 --> 10:50.230 So I'm going to move over to anime script one more time, and let's press down Ctrl S in order to save 10:50.230 --> 10:50.870 the script. 10:50.870 --> 10:52.790 And now let's move over to unity. 10:52.790 --> 10:59.540 So you can approach the same thing with this enemy one game object, as well as with this two game object 10:59.540 --> 11:05.660 as well, so you can simply create singleton pattern in this enemy two script as well as the enemy one 11:05.660 --> 11:06.220 script. 11:06.220 --> 11:07.780 So you're gonna have that. 11:07.780 --> 11:10.220 So before we do, let's have a look by now. 11:10.220 --> 11:11.940 So I'm going to click on this play button. 11:12.140 --> 11:15.060 There should be no errors in our console tab. 11:15.060 --> 11:17.900 So before we do let's have a look on this. 11:17.940 --> 11:20.860 And we're gonna do the same thing in this enemy two game object. 11:20.860 --> 11:24.340 Basically enemy two script as well as enemy one script. 11:24.340 --> 11:27.340 So we're not able to see any error in the console. 11:27.500 --> 11:31.900 So you can just ignore that error, which is not at all thing. 11:31.940 --> 11:35.460 And we can see the player game object indeed taking damage. 11:35.460 --> 11:39.740 And once it loses all of his health, we can see a message in the console tab. 11:39.740 --> 11:40.300 Just kidding. 11:40.300 --> 11:46.620 Pop up says player died because we do know once our player game object loses all of his health, then 11:46.620 --> 11:50.900 we're just calling the type function and we do know what type function really doing. 11:50.900 --> 11:53.140 So I'm going to get out of play mode by now. 11:53.140 --> 11:58.180 I hope you get the idea that how you can do it, and I'm going to do the same thing in this enemy anime 11:58.180 --> 11:59.340 to skip as well. 11:59.660 --> 12:04.620 So I'm going to open up my anime script and let's go to top of our class and let's make it public. 12:04.620 --> 12:11.300 So make sure you making it public so you can just access through another class or another script easily. 12:11.420 --> 12:15.540 And we're going to create a static parameter and we're going to call it anime two. 12:15.580 --> 12:21.740 Basically we're just creating a variable as the name of our script or this C class, and we're going 12:21.780 --> 12:24.100 to call it instant as we have done. 12:24.260 --> 12:25.660 And we're going to set. 12:25.700 --> 12:28.060 So let's use the awake function. 12:28.060 --> 12:30.980 Or you can use the start function as well. 12:30.980 --> 12:32.500 It's totally up to you. 12:32.500 --> 12:37.580 So in this script or this anime script I'm going to use the start function. 12:37.580 --> 12:41.060 And we do know start function, get call and the start of the game. 12:41.060 --> 12:45.140 And in the start of the game I'm going to check if instant is equals. 12:45.140 --> 12:47.220 Equals to null means empty. 12:47.340 --> 12:49.940 Then we're going to set instant equal to this. 12:49.940 --> 12:52.540 So we're going to set instant equal to this. 12:52.580 --> 12:55.100 Else we're going to destroy our instant. 12:55.100 --> 12:56.980 So we're going to use this else condition. 12:56.980 --> 13:00.530 And we're going to use this destroy function in order to destroy. 13:00.530 --> 13:02.570 So we're going to destroy this. 13:02.570 --> 13:04.610 And let's close that up with semicolon. 13:04.850 --> 13:07.770 And let's do the same thing in our anime one script. 13:07.770 --> 13:15.810 So I'm going to move over to my anime script or the first anime and let's create a another public static. 13:16.130 --> 13:17.810 And this will be enemy. 13:17.850 --> 13:19.970 And I'm going to call this one instant. 13:20.330 --> 13:22.570 And let's go to start function. 13:22.810 --> 13:25.930 Uh, for this script I'm going to use the awake function. 13:25.930 --> 13:32.250 So let's use this awake and this awake function get call uh, in the start of the game right before 13:32.250 --> 13:33.530 this start function. 13:33.530 --> 13:36.570 And it also get one time just one time. 13:36.730 --> 13:41.810 And we're gonna check if instance equals equals to null. 13:42.090 --> 13:47.090 Then we're going to set instant equal to this instant equal to this. 13:47.090 --> 13:48.410 So let's set that. 13:48.410 --> 13:55.410 And if in already there is an instant then we're going to destroy this instant this. 13:55.450 --> 13:56.770 And that's it. 13:57.050 --> 14:02.650 And I'm going to move over to my player script where we destroying or just damaging our player. 14:02.650 --> 14:05.050 So I'm going to move over to my player game object. 14:05.050 --> 14:11.810 So over here, as you can see we just are damaging our player and we're just using fairly taxing or 14:11.850 --> 14:17.210 heavy texting, heavy text in order to do that or in order to damage our enemy. 14:17.210 --> 14:23.170 So instead of using this, we can simply go to enemy to script, or we can simply pass the script name. 14:23.170 --> 14:25.810 So in our case this enemy to a. 14:25.970 --> 14:27.570 So we're going to go to instant. 14:27.570 --> 14:29.970 And now we're going to call that takedamage function. 14:29.970 --> 14:33.330 And let's make first bracket and then close that up with semicolon. 14:33.330 --> 14:38.930 And once I damaging enemy one then I'm going to use this enemy one script enemy. 14:38.930 --> 14:40.850 Then we will move over to instant. 14:40.850 --> 14:43.250 And we're going to call that Takedamage function. 14:43.250 --> 14:45.810 And over here it's going to take the argument. 14:45.810 --> 14:47.090 And I'm going to pass one. 14:47.090 --> 14:49.930 So it will just going to subtract by one unit. 14:50.450 --> 14:54.090 And I'm going to press down control S in order to save script. 14:54.090 --> 14:57.840 And let's do the same thing with this ground spawner as well. 14:57.840 --> 14:59.000 So it's going to be fine. 14:59.200 --> 15:00.800 So I'm going to move over to. 15:00.840 --> 15:02.120 My over here. 15:02.520 --> 15:06.520 Let's go to top of our class and let's make a public static. 15:06.840 --> 15:10.920 So let's make a public static that will be ground spawner. 15:10.920 --> 15:13.840 And I'm going to call this one instant as well. 15:14.080 --> 15:18.960 And for this script or this class I'm going to use this start function. 15:18.960 --> 15:23.360 And I'm going to check if instance x equals equals to null. 15:23.480 --> 15:26.120 Then we're going to set instant equal to this. 15:26.440 --> 15:29.120 So instant equal to this. 15:29.160 --> 15:31.200 Else we're going to destroy that. 15:31.200 --> 15:33.240 So let's use this else condition. 15:33.480 --> 15:33.960 Else. 15:34.000 --> 15:39.200 If already there is an instant then we're going to destroy this instant. 15:39.200 --> 15:40.800 So we will destroy this. 15:40.800 --> 15:42.680 And let's close that up with semicolon. 15:43.000 --> 15:45.880 And I'm going to move this curly brackets a little bit up. 15:46.120 --> 15:51.360 And let's move over to player script where basically we're just calling the ground spawner function 15:51.360 --> 15:53.200 in order to spawn our ground. 15:53.200 --> 15:54.400 So let's go there. 15:54.400 --> 15:59.440 And over here, as you can see we are we're using this find any object by type. 15:59.440 --> 16:04.480 And then we're just going over to ground spawner script and then calling the spawn ground function, 16:04.480 --> 16:07.360 which is fairly taxing as you can see. 16:07.360 --> 16:14.480 So instead of doing this, we can simply, uh, now we can simply pass our ground spawner as class name. 16:14.800 --> 16:17.040 And then we're going to move over to instant. 16:17.040 --> 16:19.760 And now we're going to call the spawn ground function. 16:19.760 --> 16:21.080 And let's make first bracket. 16:21.080 --> 16:23.080 And let's close that up with semicolon. 16:23.080 --> 16:25.960 And then we're going to press down Ctrl S to save our script. 16:25.960 --> 16:28.000 And let's move to unity by now. 16:30.320 --> 16:32.000 So just wait for to compile. 16:32.000 --> 16:36.120 And once it's done we are ready to do that basically. 16:36.160 --> 16:38.760 Basically we just calling those function. 16:38.760 --> 16:39.760 So just wait. 16:41.080 --> 16:42.760 And now it should be fine. 16:42.760 --> 16:44.840 And you can ignore this error. 16:44.960 --> 16:47.760 It's not much at all effective. 16:47.760 --> 16:49.480 So we can simply clear that. 16:49.480 --> 16:51.720 And let's click on this play button in the top. 16:51.720 --> 16:53.400 And let's have a look on this. 16:53.440 --> 16:55.720 If it's perfectly working or not. 16:55.720 --> 16:57.710 So we're going to take a look on this. 16:57.710 --> 17:01.270 So we're using singleton pattern in order to do that. 17:01.270 --> 17:05.710 And if you still a little bit worried about a singleton pattern. 17:05.710 --> 17:12.510 And if you just didn't understand it well uh, I will have a video in the resources, a link, you can 17:12.510 --> 17:20.350 go and check that out about, uh, singleton pattern that we use in this, uh, our project. 17:20.350 --> 17:22.710 So you can take a look on that. 17:22.870 --> 17:29.310 I hope you get the idea that how you can use singleton pattern in order to make your code clean, and 17:29.310 --> 17:29.990 that's it. 17:30.030 --> 17:32.030 Uh, that that's pretty fine. 17:32.030 --> 17:37.150 And also, we need to adjust our background perfectly in order to seamlessly. 17:37.150 --> 17:43.830 It's gonna, uh, see we're gonna see that it just, uh, spawning, uh, top of our, this background. 17:43.830 --> 17:50.150 So it should, uh, so we're going to, uh, take a look on this, uh, thing in the end of the, our 17:50.150 --> 17:50.630 lecture. 17:50.630 --> 17:52.270 So I'm going to get out of play mode. 17:52.310 --> 17:53.590 I hope you get the idea. 17:53.590 --> 17:57.470 And I'm going to press down Ctrl s in order to save my project.
