WEBVTT 00:00.040 --> 00:06.400 We're going to create a script in order to basically if we click on this retry button, then we want 00:06.400 --> 00:07.720 to reload the level. 00:07.720 --> 00:14.280 And if we click on this menu button, then we just want to move over to our panel scene or menu. 00:14.680 --> 00:18.160 And we don't have the menu yet, so we're going to create it later. 00:18.160 --> 00:20.400 For now we're going to print out a message. 00:20.400 --> 00:24.560 But before we do, let's create the script in order to load our level. 00:24.600 --> 00:29.360 To do so, let's head over to our project App assets and then script folder. 00:29.360 --> 00:33.160 Let's right click there create and then move over to scripting. 00:33.160 --> 00:35.680 And then click on this Monobehaviour script. 00:35.720 --> 00:40.720 Or you can simply click on this Monobehaviour script in the top, as you can notice. 00:40.720 --> 00:46.880 And you can call that script to something like scene management or something like Game Manager as well. 00:46.920 --> 00:51.880 I already created a script called Scene Management, as you can notice right over here. 00:51.880 --> 00:58.480 So we need to attach this script and to any GameObject in our hierarchy to make it work. 00:58.520 --> 01:03.750 Or we can simply create another GameObject for this script separate game object. 01:03.750 --> 01:05.430 So let's do that for it. 01:05.430 --> 01:07.190 So I'm going to move over to hierarchy. 01:07.190 --> 01:09.350 Let's right click or hit this plus icon. 01:09.350 --> 01:11.270 Let's create an empty game object. 01:11.270 --> 01:14.790 And let's call this game object to something like scene management. 01:14.790 --> 01:19.150 So I'm going to call this one scene management. 01:19.470 --> 01:22.350 And let's go over to Inspector Transform. 01:22.350 --> 01:24.670 Let's right click on it and then reset. 01:24.830 --> 01:27.230 And I'm going to select my scene Management game object. 01:27.230 --> 01:31.710 And I'm going to drag it in the top of my hierarchy so I can see all the time. 01:31.710 --> 01:34.390 And we're going to select this scene management script. 01:34.390 --> 01:38.510 And let's drag it over to this Add Component section in Inspector. 01:38.510 --> 01:42.350 And let's open up our scene management script by double clicking on it. 01:42.550 --> 01:45.950 And let's remove this update and start function. 01:45.950 --> 01:52.430 We don't need uh, so whenever we working with scene, make sure you just go to top of your class and 01:52.430 --> 01:53.790 include this namespace. 01:53.790 --> 01:59.710 And it's called using Unity engine Unity engine dot scene management. 01:59.710 --> 02:02.030 So make sure you include this namespace. 02:02.270 --> 02:10.500 Uh just move over to top of your class and include this namespace called using Unity Engine dot Scene 02:10.540 --> 02:13.020 Management, because we're gonna work with scene. 02:13.020 --> 02:13.820 So that's why. 02:14.100 --> 02:18.820 And we need to make this function public since we're going to call this function through a button. 02:18.820 --> 02:27.060 So if I move over to unity and then go over to canvas, then UI or this BG basically, and then select 02:27.060 --> 02:30.900 this retry button or this menu button, then go over to Inspector. 02:30.900 --> 02:31.780 Scroll down. 02:31.820 --> 02:33.420 We have a button component. 02:33.420 --> 02:35.780 And in the bottom we can see on click. 02:35.780 --> 02:40.020 So we can call a function over here in order to do something. 02:40.020 --> 02:44.940 So that's why we need to make those function public so we can just access it over here. 02:44.940 --> 02:49.700 So whenever we're going to click on this retry function add a retry button. 02:49.700 --> 02:51.900 Then that function just gonna trigger. 02:51.900 --> 02:52.740 So that's why. 02:52.940 --> 02:54.940 So let's move over to our scape. 02:54.940 --> 02:56.900 So we're going to create public. 02:57.180 --> 02:59.660 And for function we're going to type void. 02:59.700 --> 03:01.580 And we have to name the function. 03:01.580 --> 03:08.680 So I'm going to call this function to something like retry retry level, something like that. 03:08.680 --> 03:11.600 And let's make first bracket and some curly brackets. 03:11.760 --> 03:17.640 So inside this function what we want to do we just want to reload the scene which we are currently in 03:17.800 --> 03:20.240 or which level we are currently in. 03:20.720 --> 03:23.920 So we are currently in this uh higher. 03:24.120 --> 03:28.840 If we move over to hierarchy, we can see the name of the scene is Sample Scene. 03:29.000 --> 03:35.600 And if you want to see the build index of it then what you can do you can go to top left in unit editor 03:35.600 --> 03:36.440 says file. 03:36.640 --> 03:41.320 Then click on this build profiles in the bottom and you can see the name of the scene. 03:41.320 --> 03:43.840 So right over here it's going to be Scene List. 03:43.840 --> 03:46.160 And then click on this open scene list. 03:46.160 --> 03:49.200 And you can see the name of the scene and the build index. 03:49.200 --> 03:52.120 We can notice in the right section which is zero. 03:52.120 --> 03:56.320 So we can simply pass the name of the scene or the build index of it. 03:56.320 --> 03:58.640 So I'm going to cut this step nine right now. 03:58.640 --> 04:00.760 And let's move over to our script. 04:00.760 --> 04:05.040 And in order to load the level we need to use this scene manager. 04:05.200 --> 04:07.710 Scene manager dot load scene function. 04:07.710 --> 04:13.590 So make sure you use this function in order to load the scene or the level that you want to load up. 04:13.790 --> 04:15.790 So scene manager dot load scene. 04:15.790 --> 04:23.430 And inside this uh first bracket, we can pass the name of the scene in quotation or the index of it 04:23.630 --> 04:24.830 without quotation. 04:25.030 --> 04:27.030 But we're gonna use something else. 04:27.030 --> 04:30.630 So we're gonna use this scene manager as scene manager. 04:30.830 --> 04:32.590 Dot get active scene. 04:32.910 --> 04:37.430 Then we're going to make this first bracket, and then we're gonna use this dot, and we're going to 04:37.430 --> 04:41.350 pass the index of it and then close that output semicolon. 04:41.350 --> 04:45.430 So what basically this means scene manager dot get active scene. 04:45.670 --> 04:49.830 The active scene basically means the scene which we are currently in. 04:50.030 --> 04:57.270 So we are if we move over to unity, we can see we uh, we currently in our, uh, sample scene and 04:57.270 --> 05:00.670 then what we're doing, we just accessing the index of it. 05:00.670 --> 05:06.550 And if we move over to unity, then top left file, then build profiles so we can see the name of the 05:06.550 --> 05:07.870 scene is sample scene. 05:07.870 --> 05:11.900 in and in the right section we can see the build index is zero. 05:12.100 --> 05:15.500 So over here it's just going to be zero right away. 05:15.540 --> 05:15.900 Why. 05:16.100 --> 05:18.100 Because scenemanager dot get feet. 05:18.140 --> 05:23.980 SIM basically means the scene which we are currently in or which level we are currently in. 05:24.020 --> 05:26.740 And then we accessing the build index of it. 05:26.740 --> 05:29.260 And we saw the build index is zero. 05:29.300 --> 05:31.340 The scene which we are currently in. 05:31.500 --> 05:39.500 And we do know currently in basically the scene is sample scene and the build index of it is zero. 05:39.500 --> 05:45.540 So basically means this scene manager dot load scene function is going to load the scene which we are 05:45.540 --> 05:46.500 currently in. 05:46.580 --> 05:49.460 Basically it's going to load up the samples in itself. 05:49.620 --> 05:51.420 So I hope you get the idea. 05:51.500 --> 05:56.260 And now we're going to press down Ctrl s on our keyboard in order to save our script. 05:56.260 --> 05:58.700 And then we're going to move over to unity. 05:59.220 --> 06:06.180 And we need to hook this retry button with that retry retry level function. 06:06.300 --> 06:07.620 So just wait a moment. 06:08.260 --> 06:15.490 And once our compilation is done, we can just go ahead and we can hook this retry button with our retry 06:15.530 --> 06:16.410 level function. 06:16.530 --> 06:20.050 Now the, uh, now, uh, the script gets compiled. 06:20.130 --> 06:26.290 So now what we have to do, we need to move over to hierarchy, then canvas game over ui bg. 06:26.290 --> 06:28.450 And then let's select this retry button. 06:28.450 --> 06:29.890 Let's go over to Inspector. 06:29.890 --> 06:34.770 Scroll down to the button component and we can call the function over here on click. 06:34.770 --> 06:37.810 So we need to click on this plus icon. 06:37.810 --> 06:43.050 And we need to drag the game object in which game object the script is sitting on. 06:43.050 --> 06:48.370 So if I select my Scene Management GameObject in the hierarchy and then go over to Inspector, we can 06:48.370 --> 06:52.810 notice Scene Management Script is sitting on this scene Management game object. 06:52.810 --> 06:56.090 So that's why we need to select this scene management game object. 06:56.090 --> 06:59.530 And we need to drag it over here and it says no function. 06:59.530 --> 07:05.210 So just click there and we will go over to scene management script or Scene Management class. 07:05.210 --> 07:08.970 And in there we can see we created the retry level function. 07:08.970 --> 07:10.170 So we're going to choose that. 07:10.210 --> 07:15.510 It It's basically means as soon as we're going to click on this retry function, then that function 07:15.510 --> 07:17.390 is just going to call out which retry. 07:17.430 --> 07:23.230 So basically we're just moving over to this scene management class or this script. 07:23.230 --> 07:26.910 And then we just call it we just triggering this function. 07:26.910 --> 07:32.510 Basically whenever we're going to click on that retry button then this function just gonna get called. 07:32.510 --> 07:37.550 And what this function is really doing, it's just loading the scene which we are currently in. 07:37.590 --> 07:38.750 As you can notice. 07:38.910 --> 07:41.390 Now we're gonna move over to unity. 07:41.630 --> 07:43.990 And let's click on this play button in the top. 07:43.990 --> 07:45.910 And let's have a look on this. 07:45.910 --> 07:51.750 So as soon as we're going to click on that retry button then retry level a function just going to call 07:51.750 --> 07:52.070 out. 07:52.070 --> 07:56.430 And we do know what we're doing inside that retry level function. 07:56.430 --> 08:01.070 So just wait a moment and we're going to take damage from this. 08:01.110 --> 08:03.990 You can simply say this show or this fire. 08:04.310 --> 08:10.270 So as you can see our retry basically this BG just pops up. 08:10.430 --> 08:14.140 And if I just go ahead and then click on this retry button. 08:14.140 --> 08:19.740 As you can notice, as soon as we click we just loaded the scene which we are currently in. 08:19.740 --> 08:24.780 So we are currently in sample scene and we just accessing the build index of it. 08:24.780 --> 08:27.380 And we do know the build index is zero. 08:27.380 --> 08:30.580 So basically just it just reloading itself. 08:30.940 --> 08:33.020 And let me show you one more time. 08:33.020 --> 08:34.860 So let me show you. 08:36.220 --> 08:41.700 And now we can just click on it retry button in order to reload the level. 08:41.700 --> 08:45.060 And if we just go ahead and then click on this menu button. 08:45.100 --> 08:49.980 This button is doing nothing currently and we don't have the menu scene yet. 08:49.980 --> 08:55.380 So for now we're gonna print out a message if this button is working perfectly or not. 08:55.380 --> 08:57.180 So we're gonna check that out. 08:57.180 --> 09:01.220 And if we click on this retry button then we just reloading the level. 09:01.220 --> 09:03.540 So we're gonna get our get out of play mode. 09:03.540 --> 09:07.100 And now let's create another function for this menu button. 09:07.100 --> 09:11.180 So let's move over to our scene management class or script. 09:11.180 --> 09:14.410 And let's make another function for that menu button. 09:14.410 --> 09:17.570 So we're going to make public void for function. 09:17.570 --> 09:19.690 And we're going to call this a load menu. 09:19.690 --> 09:22.090 Or let's simply call it menu. 09:22.130 --> 09:24.850 Let's make first bracket and some curly brackets. 09:24.850 --> 09:26.970 So we don't have the menus in yet. 09:26.970 --> 09:31.370 So if this button is working or not we're going to print out a message. 09:31.370 --> 09:34.930 So I'm going to type this Debug.log for printing out message. 09:34.930 --> 09:38.050 And we're going to say something like uh load menu. 09:38.050 --> 09:42.010 So let's say something like load menu and load menu. 09:42.010 --> 09:44.170 And let's close that up with semicolon. 09:44.170 --> 09:44.650 Sorry. 09:45.010 --> 09:47.410 We're going to close that off with a semicolon. 09:47.410 --> 09:50.210 And we're going to press down Ctrl S to save our script. 09:50.210 --> 09:52.130 And now let's move over to unity. 09:52.370 --> 09:56.010 So we need to hook that menu function with our menu button. 09:56.010 --> 10:00.610 So as soon as we're going to click on this menu button that function just gonna trigger. 10:00.610 --> 10:06.250 And what that function is really doing is just printing out the message in the console says load menu. 10:06.290 --> 10:08.850 As you can notice inside this function. 10:08.850 --> 10:13.050 So we're going to select our console tab in order to see the message. 10:13.050 --> 10:14.920 So just wait a little moment. 10:14.920 --> 10:17.040 So now if I select my console tab. 10:17.320 --> 10:23.120 But before we do, make sure you select your menu button underneath your game object, underneath your 10:23.160 --> 10:24.320 Game Over UI. 10:24.440 --> 10:27.920 Then go over to Inspector and make sure you select the menu button. 10:27.920 --> 10:29.360 Then go over to Inspector. 10:29.520 --> 10:33.440 Scroll down to the button component and then click on this plus icon. 10:33.440 --> 10:37.600 And we do know that we need to drag the game object in which game object the. 10:37.680 --> 10:40.760 This basically script is sitting on. 10:40.760 --> 10:42.720 So in our case scene management. 10:42.720 --> 10:46.040 So we're going to select that and let's drag it over to that field. 10:46.040 --> 10:47.400 And it says no function. 10:47.400 --> 10:52.480 So let's click there and let's go to scene management script or scene management class. 10:52.480 --> 10:55.440 And we can see the menu function right over here. 10:55.440 --> 10:58.480 So we're going to choose this menu function for this menu button. 10:58.480 --> 11:03.520 So as soon as we're going to click on this menu button that menu function just gonna trigger. 11:03.520 --> 11:05.480 And what this menu function is doing. 11:05.480 --> 11:10.480 It's basically printing out the message in the console says load menu as you can notice. 11:10.480 --> 11:13.960 So now let's move over to unity and let's select the console tab. 11:13.960 --> 11:18.420 And let's click on this play button in the job in order to play our game. 11:18.420 --> 11:19.580 And let's take a look. 11:19.580 --> 11:24.900 So as soon as we're going to click on that menu button, that menu function just gonna trigger and that 11:24.900 --> 11:27.980 menu function basically just loading up the message. 11:28.140 --> 11:28.620 Sorry. 11:28.740 --> 11:31.260 Printing out the message says load menu. 11:31.380 --> 11:36.540 So let's take damage from this or this wraps first. 11:39.060 --> 11:42.020 And we can notice it gets pop up. 11:42.020 --> 11:45.620 So now if I just go ahead and then click on this menu button. 11:45.740 --> 11:51.420 As you can see as soon as we're clicking this menu button, if we move over to our console tab, we 11:51.420 --> 11:54.380 can see a message just getting pop up says menu. 11:54.380 --> 11:59.940 So we basically are printing out this message to check if this button is working or not. 11:59.980 --> 12:02.420 Because we don't have the menus in yet. 12:02.460 --> 12:03.620 We need to create. 12:03.620 --> 12:06.380 So that's why for now we just printing out the message. 12:06.380 --> 12:12.140 So as soon as we're clicking on this menu button, that menu function just calling and what that menu 12:12.140 --> 12:18.090 function is doing, it's basically the printing out the message load menu in our console tab, As you 12:18.090 --> 12:18.810 can notice. 12:18.810 --> 12:24.290 So I hope you get the idea that how you can do it and we're gonna get out of play mode and make sure 12:24.290 --> 12:25.850 you select the parent game object. 12:25.850 --> 12:32.290 So in our case this game over UI and go over to Inspector then overrides and then click on this apply 12:32.290 --> 12:32.690 all. 12:32.690 --> 12:37.370 So the changes you've made inside this game over UI game object it's going to be save. 12:37.370 --> 12:41.010 And let's also make this scene management game object a prefab. 12:41.050 --> 12:41.450 Why? 12:41.490 --> 12:43.810 Because we need this scene management script. 12:44.210 --> 12:44.970 So that's why. 12:45.010 --> 12:48.850 And the scene management script is sitting on the scene management game object. 12:48.850 --> 12:51.090 So that's why we're gonna make this one prefab. 12:51.090 --> 12:57.250 So we're gonna have the copy so we can use this scene management script to any scene that we want. 12:57.290 --> 13:02.770 So I'm going to select my project tab and let's select the Scene Management GameObject in the hierarchy. 13:02.930 --> 13:08.330 And let's drag it in inside this prefabs folder in order to turn it into a prefab. 13:08.530 --> 13:11.570 So as you can notice, we just turn it into a prefab. 13:11.610 --> 13:19.530 Basically, we have the copy of it by now, and we can use it into another level or another scene as 13:19.530 --> 13:19.930 well.
