WEBVTT 00:00.040 --> 00:06.400 We're going to use for loop in order to spawn a three ground in the start of the game instead of spawning 00:06.400 --> 00:07.000 one. 00:07.000 --> 00:07.960 So let's do that. 00:07.960 --> 00:11.240 So we're going to select our Ground spawner GameObject in the hierarchy. 00:11.240 --> 00:15.360 And let's open up the ground spawner script by double clicking on it. 00:15.760 --> 00:20.080 So we as you can see we just uh, just calling this function. 00:20.240 --> 00:25.800 So, so what we're going to do, uh, we're going to use for loop in order to spawn uh, first three 00:25.800 --> 00:27.360 ground in the start of the game. 00:27.360 --> 00:30.480 Or you can just spawn as many ground you want. 00:30.720 --> 00:35.160 So what we will do, we will, uh, use for loop. 00:35.160 --> 00:40.440 So let's use this for and you can just, uh, tap twice on your keyboard. 00:40.440 --> 00:43.000 So basically the tap key double tap it. 00:43.280 --> 00:48.680 Uh firstly or you can say uh quickly you need to uh use this tap. 00:48.680 --> 00:49.800 So I'm going to press down. 00:49.800 --> 00:58.360 As you can see, as soon I press tap twice at the at once moment, we can see this for loop format just 00:58.360 --> 00:59.320 gets add up. 00:59.440 --> 01:05.770 And we can just do that or simply what you can do, you can just use this for and then make first bracket 01:05.770 --> 01:07.570 and then some curly brackets. 01:07.570 --> 01:12.290 And then you can see this something like I int I equal to zero. 01:13.090 --> 01:15.770 But it's pretty heavy to do. 01:15.770 --> 01:19.250 So we can simply going to use for uh tab key. 01:19.450 --> 01:22.610 So we're going to tap twice a tab key in our keyboard. 01:22.810 --> 01:24.730 So this for loop will run. 01:25.010 --> 01:29.490 And over this condition which is I is less than length. 01:29.610 --> 01:33.370 So instead of passing length we're going to pass something like uh three. 01:33.370 --> 01:35.130 So I want to spawn three ground. 01:35.130 --> 01:36.850 So that's why I just pass three. 01:36.970 --> 01:42.250 So this for loop will run until, until this condition over here breaks out. 01:42.250 --> 01:49.250 So it's gonna start a from I as you can see int I equal to zero means it's going to start from zero. 01:49.410 --> 01:53.770 So and let's suppose we uh we just set I is now zero. 01:53.770 --> 01:56.650 So we do know that zero is lesser than three. 01:56.650 --> 02:01.370 So the whatever you're gonna do inside this curly bracket, it's gonna be execute. 02:01.570 --> 02:05.410 And then in the next time this, I just going to add up one. 02:05.410 --> 02:07.770 So in this start this I is zero. 02:07.770 --> 02:10.850 So plus plus over here basically means adding one. 02:11.090 --> 02:13.170 So zero plus one is just going to be one. 02:13.170 --> 02:16.450 So the next time this for loop now I is one. 02:16.450 --> 02:18.850 And we do know that I is one. 02:18.850 --> 02:25.330 And one is still less than three I still less than three basically means the condition over here is 02:25.330 --> 02:26.170 still true. 02:26.170 --> 02:31.450 So that's why whatever you're going to do inside this curly bracket, it will execute for the second 02:31.450 --> 02:32.810 time as well. 02:32.970 --> 02:36.410 And now we're just adding one after doing this. 02:36.410 --> 02:37.650 So I is one. 02:37.650 --> 02:39.650 So one plus one is just going to be two. 02:39.810 --> 02:42.010 Now the I is two over here. 02:42.010 --> 02:44.050 So I is now two. 02:44.130 --> 02:46.890 And we do know that two is still less than three. 02:46.890 --> 02:49.610 So the condition over here is still a true. 02:49.610 --> 02:54.970 So whatever we're going to do inside this curly bracket, it's going to execute for the third time as 02:54.970 --> 02:55.330 well. 02:55.370 --> 02:58.370 Because the condition over here is totally true. 02:58.370 --> 03:01.970 So and after that, uh, I, I is now two. 03:02.010 --> 03:03.970 So two plus one is just going to be three. 03:03.970 --> 03:10.300 So the now the third time this I is now three and we do know that three is not less than three. 03:10.300 --> 03:11.340 So I is three. 03:11.700 --> 03:15.260 And we do know that three is not less than three. 03:15.260 --> 03:20.180 So whatever we're going to do inside this curly bracket now, it's not going to be executed. 03:20.180 --> 03:23.900 So because the condition over here is now totally false. 03:23.900 --> 03:30.060 So this for loop will run third time because the condition will be for the uh, till uh, the condition 03:30.060 --> 03:36.820 just going to be, uh, true, a true for third time, but in fourth time it's not going to be executed 03:36.820 --> 03:41.620 because in fourth time this condition is just going to break breaks out totally. 03:41.620 --> 03:42.460 So that's why. 03:42.620 --> 03:46.580 So this just gonna run this for loop, uh, third time. 03:46.580 --> 03:50.460 So what we're going to do in the third time, we're going to call this spawn crown. 03:50.460 --> 03:53.060 So we're going to press Ctrl X in order to cut. 03:53.060 --> 03:56.940 And we're going to paste inside this curly brackets by Ctrl V. 03:57.180 --> 04:02.540 So this spawn crown function just going to call third time because the this for loop is just going to 04:02.540 --> 04:04.100 run a third time. 04:04.300 --> 04:07.990 Uh, and the fourth time the condition over here is going to be false. 04:07.990 --> 04:13.230 So that's why the three grams is going to be spawned in the start of the game. 04:13.230 --> 04:18.590 Because inside this curly bracket, this spawn ground function is just going to run third time right 04:18.590 --> 04:18.990 away. 04:19.390 --> 04:21.630 Uh, basically this is one ground function. 04:21.630 --> 04:24.150 Just going to call uh, three times. 04:24.230 --> 04:27.470 Uh, first time, second time and third time and fourth time. 04:27.510 --> 04:30.350 The condition over just going to be false. 04:30.390 --> 04:35.670 Uh, so it's not going to run in the fourth time means, uh, the fourth time in the start of the game. 04:35.670 --> 04:39.830 We're not going to able to see any, uh, crown in the fourth time. 04:39.830 --> 04:45.350 So I'm going to make this a cut and let's press down Ctrl s in order to save our skip. 04:45.350 --> 04:47.110 And let's move over to unity. 04:47.150 --> 04:50.550 You will see in the start of the game we will have a look. 04:50.590 --> 04:55.990 The three grounds, uh, just gonna spawn right away right after the game start. 04:55.990 --> 04:58.750 And we're gonna have a look on that as well. 05:06.270 --> 05:08.430 So now we should see. 05:08.430 --> 05:12.630 So let's click on this play button in the top in order to take a look on this. 05:13.390 --> 05:18.550 And we will see that in the start of the game a three grams just gonna spawn. 05:24.270 --> 05:29.230 And we can see I'm going to click on this pause button in the top in order to pause my game. 05:29.590 --> 05:36.190 And we can see that, uh, three grams just gets spawned and the fourth crown spawn once we trigger 05:36.190 --> 05:42.670 it with this box Collider 2D, and we can see three ground just spawned in the start of the game one, 05:42.670 --> 05:43.830 two, and three. 05:44.110 --> 05:48.630 And this one will just get spawn because we trigger it with that box. 05:48.630 --> 05:52.910 Collider 2D, and we're just getting some, uh, error. 05:52.950 --> 05:54.310 We can ignore that. 05:54.310 --> 05:55.750 I hope you get the idea. 05:55.790 --> 06:03.030 Let's get out of play mode instead of spawning three, we can spawn as many ground we want in the start 06:03.030 --> 06:06.190 of the game, so you can just make a variable for that. 06:06.190 --> 06:11.920 Basically, to do that, move over to script and then go to top of your class and you can just make 06:11.960 --> 06:17.400 a public variable to just adjust it underneath your ground spawner script. 06:17.400 --> 06:20.840 So you can just make a variable in or how. 06:21.040 --> 06:22.280 In order to how many. 06:22.640 --> 06:23.120 Crowns. 06:23.120 --> 06:25.960 You just want to spawn in the start of the game. 06:25.960 --> 06:28.000 So I'm going to make a variable public. 06:28.240 --> 06:34.320 And we're going to make it public so we can adjust underneath our ground spawner script in Inspector. 06:34.320 --> 06:37.440 And that will be in like whole numbers 012, three, four. 06:37.440 --> 06:41.560 And we can call something like number of crowns. 06:41.600 --> 06:45.800 So we're going to call it number of rounds. 06:46.000 --> 06:51.760 And we will set equal to by default value I'm going to set something like three because I want three 06:51.800 --> 06:52.200 crowns. 06:52.200 --> 06:54.320 And we're going to close that up with semicolon. 06:54.320 --> 06:59.160 And over here instead of passing three we're going to pass this number of ground. 06:59.160 --> 07:01.720 So the number of ground by default we set three. 07:01.720 --> 07:02.520 So three ground. 07:02.560 --> 07:04.440 So this is going to be three right away. 07:04.440 --> 07:06.160 So I'm going to remove this three. 07:06.200 --> 07:10.760 Instead of hard coding we're going to pass the variable which is number of rounds. 07:10.960 --> 07:14.160 And we're going to press down Ctrl S in order to save our skip. 07:14.160 --> 07:15.960 And now let's move over to unity. 07:16.600 --> 07:19.880 And so this a number of grounds by default we set. 07:19.880 --> 07:25.320 So this just going to be three right away means the uh three grams just gonna spawn in the start of 07:25.320 --> 07:25.640 the game. 07:25.640 --> 07:31.600 And we do know we just made it public so we can, uh, adjust this number as many times we want or the 07:31.600 --> 07:33.880 number we would like to go with. 07:33.880 --> 07:35.400 So let's go to unity now. 07:35.400 --> 07:41.000 And we can see underneath our ground spawner script number of ground variable just gets pop up. 07:41.000 --> 07:43.080 And we can just click on this play button. 07:43.120 --> 07:48.360 And in order to check that and we're gonna able to see three ground just going to spawn right after 07:48.360 --> 07:49.680 the game start. 07:49.680 --> 07:51.520 But we can adjust this number. 07:51.520 --> 07:53.440 So that's why we just made it public. 07:53.600 --> 07:55.760 So we uh we can do it. 07:55.800 --> 07:59.400 As you can see in the start of the game, three ground just gets spawn. 07:59.440 --> 08:00.880 Let's get out of play mode. 08:00.880 --> 08:08.400 And you can just choose this number of ground as well by over here as many ground you want in the start 08:08.400 --> 08:08.960 of the game. 08:08.960 --> 08:10.320 It's totally up to you. 08:10.320 --> 08:15.680 I hope you get the idea that how you can use for loop to do specific things.
