WEBVTT 00:00.040 --> 00:02.080 We will use singleton pattern. 00:02.520 --> 00:07.120 So instead of find any object of type we're going to use singleton pattern. 00:07.280 --> 00:13.720 And if you don't know what is singleton pattern then you can uh you can see the previous lecture. 00:13.720 --> 00:19.520 It's it may be something around lecture number 38 or 30 9 or 40. 00:19.560 --> 00:21.200 So you can check that out. 00:21.240 --> 00:22.880 I already explained it. 00:23.000 --> 00:26.680 What is singleton pattern and how you can use that. 00:26.760 --> 00:28.720 So we gonna do that. 00:28.760 --> 00:31.600 Basically we just want to implement our code. 00:31.720 --> 00:36.440 So I'm going to select my player game object and let's go over to Inspector then player Skip. 00:36.440 --> 00:40.720 And let's double click on that in order to open up in Visual Studio. 00:41.120 --> 00:47.480 Uh so as you can notice right over here we're using this find any object of type camera check. 00:47.480 --> 00:48.840 And this this check. 00:48.880 --> 00:51.120 As you can see it's pretty long. 00:51.120 --> 00:55.880 So instead of doing that doing this we're going to use the singleton pattern. 00:55.880 --> 01:00.320 So we'll so simply we're just going to move over to our camera shake script. 01:00.320 --> 01:07.350 And we will go to top of our class, and we're going to make it public so we can access public, and 01:07.350 --> 01:09.190 we're gonna use static. 01:09.190 --> 01:15.590 So we using this static so we can simply access any variable function from this class. 01:15.910 --> 01:19.110 So without basically typing anything like that. 01:19.110 --> 01:22.670 So we can directly uh directly access. 01:22.670 --> 01:29.950 So that's why we type static and we need to uh, we basically have to name the variable which is our 01:29.950 --> 01:30.310 camera. 01:30.710 --> 01:34.310 So basically the we need to type the script name. 01:34.550 --> 01:39.190 And we need, need to uh, we basically need to name the variable. 01:39.190 --> 01:41.870 So let's call it instance something like that. 01:41.870 --> 01:44.110 And let's close that up with semicolon. 01:44.110 --> 01:48.910 And if you little bit confused then you can just go ahead and check that lecture. 01:49.310 --> 01:53.430 I have explained it in the Endless runner courses. 01:53.430 --> 01:56.510 And the lecture number may be something like 38. 01:56.510 --> 01:58.230 So you can check that out. 01:58.590 --> 02:00.350 So we're going to use the start function. 02:00.350 --> 02:02.430 So let's use this start That function. 02:02.590 --> 02:09.150 So what we want to do over here, we just want to check if there is a no instance, then we're going 02:09.150 --> 02:11.070 to set the instance of this class. 02:11.430 --> 02:18.310 And if they are already instance basically an object for this class then we're going to destroy that. 02:18.550 --> 02:20.030 So firstly we will check. 02:20.030 --> 02:21.630 So let's use this if condition. 02:21.630 --> 02:24.550 Let's make first bracket and some curly brackets. 02:24.550 --> 02:30.750 And we want to check if our instance equals equals to null means we don't have it. 02:30.750 --> 02:36.350 So what we will do we will set the instance equal to this, instance equal to this. 02:36.350 --> 02:42.310 And let's suppose let's suppose there is a already instance of this camera check script. 02:42.310 --> 02:43.790 So we're gonna destroy that. 02:43.790 --> 02:44.430 So else. 02:44.430 --> 02:48.670 If they are already a instance then what we're gonna do, we're gonna destroy that. 02:48.670 --> 02:53.870 So we're going to use this destroy function, and it's going to take the game object that we want to 02:53.910 --> 02:54.510 destroy. 02:54.510 --> 02:57.230 So we want to destroy this instance itself. 02:57.230 --> 03:01.310 So we're going to pass this this and let's close that up with semicolon. 03:01.310 --> 03:06.900 And we're going to press down Ctrl s to save our ship, and now we can just move over to our player 03:06.900 --> 03:07.260 ship. 03:07.300 --> 03:08.100 Enemy one. 03:08.140 --> 03:08.900 Enemy two. 03:09.180 --> 03:13.180 And we can just directly access the check function without typing. 03:13.340 --> 03:17.620 Like find any object by type, any object by type. 03:17.780 --> 03:21.100 And inside those arrows, we need to pass the script name. 03:21.380 --> 03:23.100 So we don't need to do that. 03:23.260 --> 03:28.780 And we can just directly access the check function from any class that we want. 03:28.980 --> 03:33.220 So I'm going to open up my enemy one game object first and then enemy two. 03:33.620 --> 03:38.900 And we're going to call the function there once our enemy one or enemy two game object. 03:38.900 --> 03:43.540 Just gonna just gonna take damage or this player game object. 03:43.900 --> 03:50.500 So we storing all of the information in this instance parameter right over here, as you can see. 03:50.740 --> 03:53.700 And we're storing all of this like this check function. 03:53.700 --> 03:58.540 All of these parameters start function and all of this into this instance. 03:58.540 --> 04:01.860 So basically we need to go over to this camera check then instance. 04:01.860 --> 04:07.770 And we can just access basically call the seek function and we can just do that instead of typing. 04:07.810 --> 04:09.490 Find any object by type. 04:09.610 --> 04:11.770 Now the compilation is done. 04:11.770 --> 04:15.370 So let's go to script and sorry let's go to unity Editor. 04:15.610 --> 04:18.690 And I'm going to select my player game object in the hierarchy. 04:18.690 --> 04:21.770 And let's open up the player script by double clicking on it. 04:21.770 --> 04:24.530 And let's move over to our Takedamage function. 04:24.530 --> 04:27.930 So over here as you can notice we taking damage. 04:27.930 --> 04:29.850 So we need to check our camera. 04:29.850 --> 04:32.850 And we're using this find any object by type. 04:32.850 --> 04:39.650 So instead of doing this we can directly uh put the directly put the class name which is camera. 04:40.050 --> 04:42.690 And then we're going to access the instant. 04:42.690 --> 04:47.330 And we do know we stored all of the information this instant parameter. 04:47.330 --> 04:49.010 So we're gonna go to instant. 04:49.010 --> 04:54.450 And then we're gonna call the shake function which is we need to type the shake function. 04:54.450 --> 04:56.450 And now we need to make first bracket. 04:56.450 --> 04:58.450 Then close that up with semicolon. 04:58.450 --> 05:02.250 And we definitely know that this shake function as a first argument. 05:02.250 --> 05:04.410 It's going to take the duration of the shake. 05:04.450 --> 05:10.890 So I'm going to pass something, a smaller number, something a few seconds, something like uh, 0.1 05:10.930 --> 05:11.330 F. 05:11.330 --> 05:17.490 And the second thing, it's going to take the intensity with how much intense we want to shake our camera. 05:17.850 --> 05:21.290 So we're going to check with something like three F or three unit. 05:21.490 --> 05:22.850 So what are we doing. 05:22.890 --> 05:28.330 We simply going over to this camera shake script and then going over to this instant parameter. 05:28.330 --> 05:32.530 And by this instant parameter we basically calling this shake function. 05:32.530 --> 05:34.850 As you can notice right over here. 05:34.850 --> 05:36.850 And we're going to copy that line of code. 05:36.850 --> 05:39.850 So let's move over to our player script one more time. 05:39.850 --> 05:41.850 And let's copy this by Ctrl C. 05:42.090 --> 05:46.010 And make sure you press Ctrl S in order to save your script. 05:46.170 --> 05:48.810 And we will move over to our anime one. 05:49.010 --> 05:50.410 And let's remove this. 05:50.410 --> 05:52.730 Find any object by type. 05:52.730 --> 05:58.610 Instead of doing that, we're going to paste this line of code which is camera shake uh, dot instant 05:58.650 --> 05:59.290 dot shake. 05:59.330 --> 06:04.090 Basically we're just going over to that camera shake script, then going over to instant. 06:04.090 --> 06:08.360 And by this instant we which is calling the save function, as you can notice. 06:08.560 --> 06:15.440 And if you, uh, you can just play around with the value, uh, how much intense or how much duration, 06:15.480 --> 06:17.560 you just want to shake your camera. 06:17.680 --> 06:22.360 So for my enemy cases, I'm just gonna do a little bit higher. 06:22.640 --> 06:26.200 Uh, something like 0.2, uh, point two duration. 06:26.400 --> 06:29.560 And also, I just want to increase the intensity. 06:29.560 --> 06:31.400 Something around four unit. 06:31.560 --> 06:33.680 And I'm going to copy this line of code. 06:33.680 --> 06:36.680 And now let's move over to our enemy two script. 06:36.840 --> 06:42.760 And before you do that make sure you press on control S as well inside this animation script. 06:42.760 --> 06:45.560 So whatever changes you made, it's gonna be saved. 06:45.720 --> 06:51.440 And now we're just gonna move over to our enemy two script and let's move over to Takedamage function. 06:51.440 --> 06:59.080 Over here we can see enemy is taking damage, so let's paste the face that line of code as well over 06:59.080 --> 06:59.640 here. 06:59.640 --> 07:02.880 And now I'm going to press down Ctrl S to save my script. 07:02.880 --> 07:04.920 And now let's move over to unity. 07:04.920 --> 07:11.710 And you will see as soon as our enemy or player just gonna take damage, the camera will start shaking 07:11.950 --> 07:16.110 because we just calling the shape function and we just type static. 07:16.110 --> 07:23.270 So we just type static because we can directly access any value or any function as you seen. 07:23.270 --> 07:25.910 So that's why we need to type public static. 07:26.070 --> 07:30.590 And the class name and the parameter name that you want to name. 07:30.870 --> 07:36.510 So now if we just go ahead and then click on this play button in the top. 07:36.510 --> 07:42.790 You will see as soon as we can take damage from this enemy one game object or from this player game 07:42.830 --> 07:45.430 object camera will start shaking. 07:46.830 --> 07:48.670 So just wait a little moment. 07:52.230 --> 07:58.190 So now if we take damage, as you can see, indeed we take camera is shaking. 07:58.190 --> 08:06.190 But once I, uh, basically attack on my enemy one game object, we can see the camera is shaking more 08:06.190 --> 08:13.590 intensely because we just as a second argument, we pass the intense a little bit higher as compared 08:13.590 --> 08:15.150 to our player one. 08:15.310 --> 08:17.750 Sorry from this player game object. 08:17.750 --> 08:23.790 So I hope you get the idea that how you can do it, as you can see, uh, as you can notice, we taking 08:23.830 --> 08:28.750 damage and the camera just shaking and that's fine. 08:28.750 --> 08:31.150 And we can attack in order to shake. 08:31.630 --> 08:33.390 So this are working fine. 08:33.990 --> 08:37.390 And we're gonna do the same thing with enemy two game object. 08:37.390 --> 08:39.870 And we do know that we already done it. 08:39.870 --> 08:44.630 So I'm going to get out of play mode and I'm going to select my enemy one game object. 08:44.630 --> 08:48.670 And let's uh, let's disable for a few moment. 08:48.670 --> 08:51.790 So I'm going to select my enemy one GameObject in the hierarchy. 08:51.830 --> 08:53.310 Let's go over to Inspector. 08:53.310 --> 08:55.950 And we're gonna uncheck basically disabling that. 08:55.990 --> 08:59.870 And now we're going to select our enemy to let's go over to Inspector. 08:59.870 --> 09:01.030 And we're going to check this. 09:01.030 --> 09:04.670 Basically we just enabling our enemy to game object. 09:04.670 --> 09:08.070 And let's check with this enemy to game object. 09:08.070 --> 09:08.710 So that's why.
