WEBVTT 00:00.040 --> 00:02.920 We need to hook this button with some certain function. 00:02.920 --> 00:06.920 So we will use the scene management script as we created before. 00:07.520 --> 00:11.720 But before we do, let's move over to this sample scene by double clicking on it. 00:12.720 --> 00:18.360 Because we have the Scene Management GameObject underneath our uh, sample scene, we can see in the 00:18.360 --> 00:19.000 hierarchy. 00:19.240 --> 00:21.160 So we need to make this one prefab. 00:21.160 --> 00:22.360 So we're going to have the copy. 00:22.360 --> 00:28.480 And then we can use uh because we have this scene management script is attached to scene management 00:28.520 --> 00:31.360 game object as you can see in the inspector. 00:31.360 --> 00:33.000 So we will make this one prefab. 00:33.000 --> 00:36.520 And then we're going to use it in our scene as well. 00:36.520 --> 00:39.960 So we're going to use the scene management script one more time. 00:39.960 --> 00:43.640 So we don't need to create another script to manage the scene. 00:43.640 --> 00:48.560 So let's select the Scene Management GameObject in the hierarchy, and let's drag it over to this prefabs 00:48.560 --> 00:50.840 folder in order to make it prefab. 00:50.880 --> 00:53.560 And now we're gonna move over to our scene. 00:53.560 --> 00:55.480 So let's head over to this scenes folder. 00:55.480 --> 00:59.750 Let's double click on this scene and we will click on this save button. 00:59.910 --> 01:04.750 Uh, so basically, whatever changes we made inside this sample scene, it's going to be saved. 01:04.750 --> 01:06.550 And I really want to save that. 01:06.550 --> 01:08.550 So that's why I'm going to click on this save. 01:08.710 --> 01:14.550 And as soon as we click save we can see we just moved over to this scene. 01:14.590 --> 01:19.710 And now I'm gonna move over to my project tab assets and then prefabs folder one more time. 01:19.990 --> 01:23.390 And I have the scene Management game object over here. 01:23.390 --> 01:27.870 So let's select that game object or that prefab of that scene management game object. 01:27.870 --> 01:32.230 And we will drag it in this hierarchy in order to use it one more time. 01:32.230 --> 01:36.670 And we can see we have the scene Management GameObject in the hierarchy. 01:36.670 --> 01:41.430 And inside this scene management game object, we can see we have the scene management script. 01:41.430 --> 01:43.590 So let's open that scene management script. 01:43.590 --> 01:45.870 But before we do let me explain. 01:45.870 --> 01:49.390 So once we click on this play button we want to play our game. 01:49.390 --> 01:54.750 And once we click on this abort button then we just want to move over to about a menu. 01:54.750 --> 01:59.870 And once we click on this exit button then we're going to quit our application or the game. 01:59.870 --> 02:01.270 We just want to exit. 02:01.270 --> 02:07.550 So let's double, double click on this scene management script and we will make, uh, more function 02:07.550 --> 02:11.470 one for our, uh, play button and one for our exit button. 02:11.470 --> 02:14.830 And we will talk about that about button later on. 02:15.110 --> 02:21.310 And I'm gonna move over to my top of our class, and we will make the function over here, and we will 02:21.310 --> 02:27.110 make that function public because we're going to call this function uh, from click event means whenever 02:27.110 --> 02:28.990 we're going to click on that play button. 02:28.990 --> 02:30.870 And then we will call the play function. 02:30.870 --> 02:33.870 So let's make a function of for our play button. 02:34.030 --> 02:35.790 And let's make that one public. 02:35.790 --> 02:37.510 For function we will type for it. 02:37.510 --> 02:39.110 And we have to name the function. 02:39.110 --> 02:44.350 I'm going to say something like play game and let's make first bracket and some curly brackets. 02:44.350 --> 02:50.190 And what we want to do inside this function, we just really want to load up the scene, uh, load up 02:50.190 --> 02:54.270 the scene or the sample scene or which scene we are playing our game. 02:54.510 --> 03:01.260 So we will use this in manager dot load scene function in order to load up the scene and make sure you 03:01.260 --> 03:07.220 just go to top of your class before you use this function, include this namespace called using Unity 03:07.260 --> 03:09.500 Engine dot Scene Management. 03:09.500 --> 03:15.780 It's going to allow us, in order to use this scene manager dot seed function in order to load our scene. 03:15.780 --> 03:22.020 And inside this load scene in this brackets, we need to pass in quotation the name of the scene, or 03:22.020 --> 03:24.620 you can simply pass the bill index of it. 03:24.620 --> 03:30.100 So, uh, in this play game function, we just load up the scene that in which scene we are playing 03:30.100 --> 03:30.820 our game. 03:30.820 --> 03:36.100 And we do know the name of the scene is sample scene, in which scene we just playing our game. 03:36.100 --> 03:40.580 And if you just want to take a look of it then just move over to unity. 03:40.580 --> 03:42.260 In the top left you can see file. 03:42.260 --> 03:45.300 So just click there and then click on this Build Profiles. 03:45.460 --> 03:48.220 And you can see the name of the scene over here. 03:48.220 --> 03:51.540 And uh so basically you will be in windows. 03:51.540 --> 03:57.380 Then click on this open scene list over here, and as soon as we click, we can see the name of the 03:57.380 --> 04:00.540 scene is a left side, which is sample scene and the build index. 04:00.540 --> 04:02.860 We can see in the right side which is zero. 04:02.860 --> 04:07.540 So we can simply pass the build index of this scene as well as name of the scene. 04:07.540 --> 04:12.620 So I'm going to pass my name of the scene which is sample scene or in which scene you were playing our 04:12.620 --> 04:13.020 game. 04:13.260 --> 04:19.020 Or you can check that by going over to this project tab, then assets and then since folder or where 04:19.020 --> 04:19.940 you have the scene. 04:19.940 --> 04:25.820 So if I just double click on this sample scene, we can see in this sample scene we are playing our 04:25.820 --> 04:26.140 game. 04:26.140 --> 04:28.460 And you can take a look on that as well. 04:28.500 --> 04:30.660 By moving over to this hierarchy. 04:30.660 --> 04:34.620 And in hierarchy you can see the name of the scene is Sample Scene. 04:34.620 --> 04:37.100 So I'm going to move over to my scene once again. 04:37.540 --> 04:40.260 So the name of the scene in quotation we're going to pass. 04:40.260 --> 04:42.340 So the name of the scene is sample scene. 04:42.340 --> 04:44.700 So let's pass name of the scene. 04:44.700 --> 04:48.700 So in our case sample scene sample scene. 04:48.700 --> 04:50.740 And let's close that up semicolon. 04:50.740 --> 04:54.330 Or you can simply pass without coercion the index of it. 04:54.330 --> 04:56.210 So the build index was zero. 04:56.370 --> 04:59.130 So you can pass the build index as well. 04:59.130 --> 05:00.610 But I'm not gonna do that. 05:00.610 --> 05:03.450 And let's press down Ctrl s to save our script. 05:03.450 --> 05:05.130 And let's move over to unity. 05:05.250 --> 05:07.370 And we will choose our play button. 05:07.370 --> 05:12.570 So whenever I am gonna click on this play button then I will call that play game function. 05:12.610 --> 05:15.290 And what that play game function is doing. 05:15.290 --> 05:19.570 It's basically loading up the scene in which scene we are playing our game. 05:19.570 --> 05:21.690 So just let's have a look on this. 05:21.690 --> 05:24.210 So just wait for to compile our script. 05:24.210 --> 05:26.850 And once it's done we are ready to do that. 05:26.850 --> 05:31.570 So let's go over to this hierarchy then canvas and we will move over to mano. 05:31.570 --> 05:33.570 And then let's choose this play button. 05:33.850 --> 05:37.810 So let's choose the play button underneath your menu GameObject in the hierarchy. 05:37.850 --> 05:43.970 Then go over to Inspector, scroll down to this button component and we can see on click and it says 05:43.970 --> 05:45.130 list is empty. 05:45.130 --> 05:47.330 So over here we can call the function. 05:47.330 --> 05:50.850 And in order to call the function we need to click on this plus icon. 05:50.850 --> 05:56.850 And over here we need to drag the game object in which game object the script is sitting on or attached. 05:56.850 --> 06:01.650 So in our case this scene management game object the scene management script is attached. 06:01.650 --> 06:06.010 So we will select our scene managed game Management game object in the hierarchy. 06:06.010 --> 06:08.210 And let's drag it over to that slot. 06:08.210 --> 06:09.570 And it says no function. 06:09.570 --> 06:13.330 So just click there and we do no inside the scene Management game object. 06:13.330 --> 06:15.330 The scene management script is attached. 06:15.330 --> 06:18.930 And we can see in the bottom which is scene management script. 06:18.930 --> 06:22.410 So we're just moving over to this scene management class. 06:22.410 --> 06:23.530 And over there we. 06:23.770 --> 06:26.410 We can see we just created the play game function. 06:26.410 --> 06:31.650 So we're going to choose this play game function means whenever we're going to click on this play button. 06:31.690 --> 06:36.330 And the this uh we just moving over to scene management game object first. 06:36.330 --> 06:41.370 And then from this scene management game object, we're just going over to the scene management script. 06:41.370 --> 06:45.970 And from this scene management script class we're calling the play game function. 06:45.970 --> 06:48.050 And what play game function is doing it. 06:48.120 --> 06:53.000 just loading up the scene in which scene we're playing our game and we can see the name of the scene 06:53.000 --> 06:54.320 is Sample Scene. 06:54.320 --> 06:55.760 So let's move to unity. 06:55.960 --> 06:58.440 And now let's click on this play button in the top. 06:58.480 --> 07:03.280 You will see as soon as we're going to click on this play button, the sample scene just gonna load 07:03.280 --> 07:07.000 up the or the scene in which scene which is playing our game. 07:07.000 --> 07:09.440 And you can rename the scene as well. 07:09.760 --> 07:16.760 So if I just click on this play button and as soon as we click on play button, we can see we just loaded 07:17.000 --> 07:22.440 loaded up the sample, uh sorry, sample scene or which scene we just playing our game. 07:22.440 --> 07:28.080 And if I just click on this menu button, we're not loading over or we're not getting over to Manos 07:28.080 --> 07:28.840 in yet. 07:28.880 --> 07:34.040 Basically once we click on this menu button, then we need to load up the scene as well. 07:34.040 --> 07:36.120 But we're going to take a look on that later. 07:36.120 --> 07:37.440 Let's get out of play mode. 07:37.480 --> 07:41.040 And let's uh, let's deal with this exit button now. 07:41.160 --> 07:45.840 So we will make a exit for uh, exit function for this exit button. 07:45.840 --> 07:49.360 So let's move over to script and I'm going to make it in the bottom. 07:49.360 --> 07:51.160 You can make it anywhere. 07:51.200 --> 07:53.000 It doesn't need to be in order. 07:53.000 --> 07:55.400 So we're going to make a public void. 07:55.560 --> 07:58.920 And let's call this function something like exit game. 07:59.200 --> 07:59.880 Exit game. 07:59.880 --> 08:02.720 Let's make first packet and some curly brackets. 08:02.720 --> 08:08.040 So inside this function what we're going to do we will use this application dot quit function. 08:08.040 --> 08:11.040 So make sure you just are doing as I did over here. 08:11.040 --> 08:13.040 Then close that up with semicolon. 08:13.040 --> 08:14.640 So what this function is just going to do. 08:14.640 --> 08:17.120 It's going to quit your application right away. 08:17.120 --> 08:20.400 But in unity editor it's not going to happen. 08:20.400 --> 08:23.560 It's not going to quit your application at all. 08:23.560 --> 08:29.880 But once you make the build or the game completely, then you just go ahead and then click on this exit 08:29.880 --> 08:30.480 button. 08:30.480 --> 08:36.560 Then it's gonna quit your application or the game, but it's not going to happen in unity editor. 08:36.560 --> 08:41.040 So if this function is perfectly working or not, we're going to check. 08:41.040 --> 08:46.870 So in order to check before we quit we're going to use this debug dot log function in order to print 08:46.870 --> 08:50.430 out the message in the console, and I'm going to say something like exit. 08:50.750 --> 08:56.390 Uh, so I just printing out this message, uh, for testing purposes, if it's perfectly working or 08:56.390 --> 08:58.350 not or correctly working or not. 08:58.390 --> 09:00.190 And let's close that up with semicolon. 09:00.190 --> 09:04.310 But it's not going to quit our application in unity editor. 09:04.310 --> 09:10.390 But once we meet our game totally or completely, then if we just click on that exit button, then it's 09:10.390 --> 09:15.990 gonna quit our application or the game and let's press down Ctrl S to save our script and let's move 09:15.990 --> 09:16.830 to unity. 09:16.830 --> 09:20.710 So we need to choose our exit game function for this exit button. 09:20.710 --> 09:26.510 So whenever we're gonna click on this exit button and that exit game function just gonna call. 09:26.510 --> 09:29.270 And we don't know what we have done inside that button. 09:29.270 --> 09:31.390 We just quitting our application. 09:31.390 --> 09:35.190 So let's go to Nano Game Object and let's choose the exit button. 09:35.230 --> 09:36.390 Let's go to Inspector. 09:36.390 --> 09:41.030 Scroll down to this button component and let's click on this plus icon. 09:41.030 --> 09:45.190 So we need to drag the game object in which game object the script is sitting on. 09:45.190 --> 09:47.550 So the script is sitting on this scene management. 09:47.550 --> 09:49.150 So we're going to drag right there. 09:49.150 --> 09:51.230 Let's click on this no function. 09:51.230 --> 09:54.950 Let's go to scene Management Script or Scene Management C class. 09:54.950 --> 09:58.910 And we're going to choose this exit game function for this exit button. 09:59.070 --> 10:01.550 And now let's click on this play button in the top. 10:01.750 --> 10:02.630 Uh in the top. 10:02.630 --> 10:09.270 And we will choose our console because we just printing out message and we want to see our message underneath 10:09.270 --> 10:10.590 our console tab. 10:11.310 --> 10:13.190 So let's uh select the console. 10:13.510 --> 10:16.710 And if I just go ahead and then click on this exit button. 10:16.710 --> 10:22.750 As you can see as soon as we're clicking the message in the console says exit because that exit game 10:22.750 --> 10:24.270 function is just calling. 10:24.310 --> 10:30.190 And what exit function is just doing its exit game function, it just printing out the message in the 10:30.190 --> 10:31.150 console exit. 10:31.150 --> 10:33.910 And after that it's just coding our application. 10:33.910 --> 10:39.590 And we can see that we're not quitting our application at all in unity editor. 10:39.590 --> 10:45.580 But you once you make the game completely or the build, then you can just go, go ahead and it's gonna 10:45.580 --> 10:50.540 quit your application right away once you click on this exit button. 10:50.540 --> 10:54.700 So now let's head, uh, let's talk about our mano button now. 10:54.700 --> 11:01.380 So let's get out of play mode and let's go to our project tab then since, uh sorry, this assets folder. 11:01.380 --> 11:03.380 And let's move over to these scenes now. 11:03.380 --> 11:07.060 And let's double click on the sample scene and let's click on this shape. 11:07.420 --> 11:14.380 Uh, so what we need to do we need to once we dying and clicking on that menu button, we can see with 11:14.380 --> 11:18.020 that we have seen that we not moving over to mano scene. 11:18.020 --> 11:22.220 So once we click on that mano button, we just want to load up the mano scene. 11:22.380 --> 11:26.580 So we need to and we just printing out the message in the console says mano. 11:26.580 --> 11:31.820 So let me show you, if I just click on this play button and then this player game object just loses 11:31.820 --> 11:35.940 all of his self, you will see the game over you by just going to be activate. 11:35.940 --> 11:41.580 And once we click on that mano we're not loading up the menu as at all. 11:41.940 --> 11:43.620 So let's have a look on that. 11:45.020 --> 11:47.540 Let's take damage from this enemy game object. 11:47.540 --> 11:54.740 And if I just click on this menu button by now we can see a we just printing out a message in the console 11:54.740 --> 11:56.100 says load menu. 11:56.100 --> 12:02.420 And instead of printing out message we really want to load up the menu instead of printing out message. 12:02.420 --> 12:04.460 So let's get out of play mode. 12:04.700 --> 12:10.180 And before you load up the menu scene, make sure you just go to top left file and then build profiles 12:10.180 --> 12:11.100 in the bottom. 12:11.100 --> 12:15.140 And then click on this open scene list and move over to the scene list. 12:15.300 --> 12:17.500 And over here what you need to do. 12:17.540 --> 12:20.260 You need to drag all of the scenes that you have. 12:20.260 --> 12:26.060 So we want to load up the menu scene and we can not able to see our scene in this scene list. 12:26.060 --> 12:30.340 So what we have to do, we need to drag our menu scene into this list. 12:30.340 --> 12:34.700 So we will move over to our project tab, then assets and then since folder. 12:34.700 --> 12:40.930 Because in that since since folder, we just created our scene and we can see it over here. 12:40.930 --> 12:46.370 So what we need to do, we need to select our scene, then drag it over to this scene list in this, 12:46.610 --> 12:53.210 uh, over here, in this scene list, make sure all of the scenes are in this inside this scene. 12:53.450 --> 12:56.970 If it's not, then select them and drag it over here. 12:56.970 --> 12:59.210 And I'm going to drag this scene in the top. 12:59.210 --> 12:59.530 Why? 12:59.570 --> 13:02.650 Because I want this scene to be the default one. 13:02.690 --> 13:04.690 Or once our play player games. 13:04.810 --> 13:07.370 Uh, player just start our game. 13:07.410 --> 13:09.770 I want this menu to be the default one. 13:09.770 --> 13:14.970 So that's why I just drag it, this menu in the top, and then these samples in the down. 13:15.170 --> 13:18.010 And by now we have both of this scene. 13:18.050 --> 13:22.730 We have this menu as well as as well as we have the sample scene. 13:22.730 --> 13:28.610 So let's get the cut this tab and let's uh move over to our menu function where we just printing out 13:28.610 --> 13:29.250 message. 13:29.250 --> 13:32.730 So in our case we're doing inside this scene management script. 13:32.730 --> 13:36.010 So we're going to select our Scene Management GameObject object in the hierarchy. 13:36.130 --> 13:39.610 And let's open up the scene management script by double clicking on it. 13:39.610 --> 13:45.850 And we can see over here we're just printing printing out in the printing out the message in the console 13:45.850 --> 13:46.930 says load menu. 13:46.930 --> 13:53.290 And you can notice over here and after printing out message we also want to load up the menu scene. 13:53.290 --> 13:58.210 So what we need to do we need to use this scene manager function in order to load that up. 13:58.210 --> 14:00.810 So we're going to use this scene manager dot load scene. 14:00.810 --> 14:03.210 And we do know this over here load scene. 14:03.250 --> 14:07.090 It's going to take the scene name in quotation or the build index of it. 14:07.090 --> 14:10.130 And if you just want to see that then move over to unity. 14:10.170 --> 14:16.530 Go to top left file, then build profiles and then scene list so we can see the name of the scene is 14:16.530 --> 14:20.890 nano and the build index of it we can see in the right which is zero. 14:20.890 --> 14:24.130 So we can simply pass the build index as well as the menu. 14:24.130 --> 14:29.370 So I'm going to pass the name of the scene instead of the build index, and make sure the scene is in 14:29.370 --> 14:30.930 this scene inside the scene list. 14:30.930 --> 14:34.120 If it's not then drag them as we have done. 14:34.120 --> 14:35.680 So I'm going to cut this step by now. 14:35.680 --> 14:36.880 Let's go to script. 14:37.040 --> 14:39.800 And in we're going to make a quotation. 14:39.800 --> 14:41.560 And let's pass the name of the scene. 14:41.560 --> 14:44.240 Or you can simply pass the index which is zero. 14:44.240 --> 14:46.440 And let's close that up with semicolon. 14:46.440 --> 14:50.240 But instead of passing bill index I'm going to pass the scene name. 14:50.240 --> 14:52.360 So I'm going to do inside this quotation. 14:52.360 --> 14:54.200 So the name of the scene is mano. 14:54.200 --> 14:57.280 And let's press down Ctrl S to save our script. 14:57.280 --> 14:59.280 And let's move to unity by now. 14:59.280 --> 15:01.200 And let's have a look on this. 15:05.200 --> 15:06.600 So just wait for to compile. 15:06.600 --> 15:09.200 And once it's done we are ready to do that. 15:09.840 --> 15:11.560 So I'm going to clear my console. 15:11.560 --> 15:15.280 Let's click on this play button in the top and have a look on it. 15:18.400 --> 15:18.960 How about. 15:27.280 --> 15:27.640 It. 15:27.840 --> 15:29.040 So just wait. 15:29.040 --> 15:30.400 We're going to take damage. 15:31.000 --> 15:32.280 So let's take damage. 15:32.280 --> 15:35.600 And now if I just go ahead and then click on this menu button. 15:35.960 --> 15:41.400 And as soon as we click on that menu button, we can see we just headed over to our mano scene. 15:41.400 --> 15:45.160 And we can just click on this play button in order to play our game. 15:45.160 --> 15:48.760 And we can take a look on on this once again. 15:48.760 --> 15:50.520 So let's have a look on it. 15:50.760 --> 15:51.960 So I'm going to take damage. 15:51.960 --> 15:53.720 And let's click on this menu button. 15:53.920 --> 15:59.880 And as soon as we click on that menu button we just head it over to our mano scene once again. 15:59.880 --> 16:00.920 So this is the cool thing. 16:00.920 --> 16:02.320 I hope you get the idea. 16:02.320 --> 16:05.080 And now let's talk about our about button. 16:05.080 --> 16:11.240 So I'm gonna get out of play mode and let's head over to our scenes are seen in order to do that. 16:11.240 --> 16:17.080 So I'm going to move over to my move over to my project tab and then assets and then scenes folder. 16:17.080 --> 16:21.320 And let's double click on this mano scene in order to move over to that scene. 16:21.360 --> 16:23.560 And let's talk about this about button. 16:23.560 --> 16:26.680 So I'm going to move over to my hierarchy then canvas. 16:26.840 --> 16:30.270 And let's select this mano and then this about button. 16:30.270 --> 16:35.390 So once we click on this about button then I just want to disable this menu UI. 16:35.590 --> 16:39.790 And I want to activate this about menu about menu UI. 16:39.950 --> 16:42.030 So once we click on this about button. 16:42.030 --> 16:47.150 So we will choose our about button underneath our menu GameObject in the hierarchy. 16:47.190 --> 16:48.230 Let's go to Inspector. 16:48.230 --> 16:50.270 Scroll down to this button component. 16:50.270 --> 16:54.030 And we can just click on this plus icon in order to do a action. 16:54.190 --> 16:55.830 And the action I want to do. 16:55.870 --> 17:02.390 Basically, I just want to deactivate this menu itself, and I want to activate this menu about menu. 17:02.670 --> 17:04.950 And once I click on this about button. 17:04.950 --> 17:06.910 So you need to drag the game object. 17:07.270 --> 17:10.910 Which game object just you want to activate or deactivate. 17:10.910 --> 17:13.830 So in my case I just want to deactivate this menu. 17:13.830 --> 17:16.030 So I'm going to select my menu Game Object itself. 17:16.030 --> 17:18.150 And let's drag it over to that slot. 17:18.150 --> 17:19.430 And it says no function. 17:19.430 --> 17:20.590 So just click there. 17:20.590 --> 17:22.590 And over here you can see game object. 17:22.590 --> 17:25.910 So game object basically just referencing itself hole. 17:26.070 --> 17:30.310 And we will choose the bottom in the we can see said active and it says bull. 17:30.430 --> 17:34.950 So if you just take their check, check basically means you just enabling it. 17:34.950 --> 17:39.510 But I want to disable this menu once I click on this about button. 17:39.510 --> 17:40.510 So I'm gonna disable. 17:40.590 --> 17:45.190 To disable we just have to uncheck and we're going to click on this plus icon because we're going to 17:45.190 --> 17:46.470 do one more action. 17:46.470 --> 17:54.470 And the action I wanted to I want to I want basically to do is that we want to activate our about menu. 17:54.510 --> 18:01.390 Once we click on this about button about button, then I want to disable the menu and I want to activate 18:01.390 --> 18:02.550 the about menu. 18:02.710 --> 18:08.790 So over here over here we need to drag the game object or which game object just you want to activate 18:08.790 --> 18:10.270 as a second parameter. 18:10.270 --> 18:12.150 So as a second thing. 18:12.150 --> 18:14.150 So we're going to activate our about menu. 18:14.150 --> 18:16.590 So we will select our about menu game object. 18:16.590 --> 18:18.590 And let's drag it into that slot. 18:18.590 --> 18:20.510 And we will click on this no function. 18:20.510 --> 18:24.270 We will go to game object basically means it just referencing itself. 18:24.270 --> 18:29.340 And we're going to use this set active bool function in the bottom and we're going to check it. 18:29.340 --> 18:29.580 Check. 18:29.580 --> 18:33.380 It basically means we're just activating that and let's have a look on it. 18:33.380 --> 18:38.580 So basically whenever we're going to click on this about button at the menu just gonna be deactivate. 18:38.580 --> 18:40.460 Basically gonna disable. 18:40.500 --> 18:42.780 And that's why we just leave it unchecked. 18:42.780 --> 18:45.860 And we just activating this about menu means about menu. 18:45.860 --> 18:49.860 Just gonna be activate as soon as we click on this about button. 18:49.860 --> 18:51.180 So let's have a look on it. 18:51.180 --> 18:54.580 So I'm going to click on this play button in order to play our game. 18:54.580 --> 18:56.700 And we're going to take a look on it. 18:56.700 --> 19:02.060 So as soon as we're going to click on this about button you will see this menu just gonna be deactivate. 19:02.060 --> 19:04.980 And that about menu just gonna be activate right away. 19:04.980 --> 19:05.860 So let's have a look. 19:05.860 --> 19:11.300 So if I just click on this about button, as you can see, as soon as we click about button we can see 19:11.300 --> 19:13.380 this about menu just gets activate. 19:13.380 --> 19:18.540 And that menu uh about about menu you may just get deactivate. 19:18.540 --> 19:23.180 And we can see underneath our canvas GameObject in the hierarchy as well. 19:23.180 --> 19:26.620 So the menu we can see, it just gets unchecked in the inspector. 19:26.620 --> 19:27.740 And this about button. 19:27.780 --> 19:32.580 About menu just gets a check in inspector means we just activating. 19:32.820 --> 19:39.340 And once we click on this back button then what I want to do I want to activate one more time the menu. 19:39.340 --> 19:42.420 And I just want to deactivate this about menu. 19:42.580 --> 19:44.020 So let's get out of play mode. 19:44.020 --> 19:46.020 And now we're going to choose our back button. 19:46.020 --> 19:51.700 So whenever we're going to click on that button then back button and back button, then we're going 19:51.740 --> 19:53.420 to do all of those stuff. 19:53.540 --> 19:56.220 So let's move over to this about menu by now. 19:56.220 --> 19:59.380 And let's select the back button inside this about menu. 19:59.380 --> 20:00.820 So let's select the back button. 20:00.860 --> 20:02.100 Go over to Inspector. 20:02.140 --> 20:05.820 Scroll down to Button Component and we're going to click on this plus icon. 20:05.820 --> 20:11.100 So we need to drag the game object which which game object we want to activate or deactivate. 20:11.100 --> 20:13.060 So in my case I'm going to select my menu. 20:13.060 --> 20:14.780 And let's drag it right there. 20:14.780 --> 20:17.100 And we will go to no function then Game Object. 20:17.100 --> 20:19.660 And we're going to use this set act set bool. 20:19.660 --> 20:25.690 And I'm going to check this because I just want to, uh, activate this about a new UI. 20:25.730 --> 20:27.770 Once we click on that back button. 20:27.770 --> 20:30.810 And after that, I want to deactivate the about menu. 20:30.810 --> 20:33.290 So we're going to click on this plus icon one more time. 20:33.290 --> 20:38.010 And we can just drag the game object which game object we want to disable or enable. 20:38.010 --> 20:40.090 So I'm going to select my about menu itself. 20:40.090 --> 20:42.570 Let's select that and drag it over to this slot. 20:42.770 --> 20:46.250 And we're going to click on this no function game object and set active. 20:46.250 --> 20:51.010 And I'm going to uncheck means we just disabling or disabling our about menu. 20:51.210 --> 20:56.370 As soon as we click on that back button and we're just enabling our menu UI. 20:56.410 --> 21:00.290 You can see in the inspector on click event as you can see. 21:00.290 --> 21:02.370 So I hope you get the idea of this. 21:02.370 --> 21:04.210 And let's uh, let's test it. 21:04.210 --> 21:07.130 So I'm going to click on this play button to play our game. 21:07.130 --> 21:10.250 And we will test uh about this about button. 21:10.250 --> 21:14.170 So as soon as we're going to click on this about button you will see the menu UI. 21:14.210 --> 21:16.090 Just gonna be uh disable. 21:16.090 --> 21:18.410 And the about menu is just going to be activate. 21:18.410 --> 21:20.290 So let's click on this about button. 21:20.330 --> 21:26.650 and we can see as soon as we click on that about button, we can see that this about menu just gets 21:26.690 --> 21:30.010 activate and that menu UI just gets deactivate. 21:30.010 --> 21:35.730 And now if I just click on this back button and we can see as soon as we click on that back button, 21:35.770 --> 21:39.330 we, we can see that this menu just gets activate. 21:39.330 --> 21:42.970 And that about menu gets deactivate or disable. 21:42.970 --> 21:50.010 So basically that this is the thing that how you can use a button to do specific things or the things 21:50.010 --> 21:51.690 that you really want to do. 21:52.130 --> 21:57.930 A this is a pretty short way to do, and this seems pretty much cool to do it. 21:57.930 --> 22:02.730 I hope you get the idea that how you can do so I'm going to get out of play mode and let's select the 22:02.730 --> 22:03.770 parent game object. 22:03.770 --> 22:09.810 Let's go to overrides Apply all, and I'm going to do the same thing over with this about menu game 22:09.850 --> 22:10.970 object as well. 22:10.970 --> 22:13.010 Let's go to overrides apply all. 22:13.450 --> 22:14.490 And now it's saved. 22:14.490 --> 22:19.490 And I'm going to press down Ctrl s on my keyboard in order to save my project.
