WEBVTT 00:00.120 --> 00:05.800 Instead of spawning the a specific one, we're going to choose a random ground and then we're gonna 00:05.840 --> 00:06.520 spawn it. 00:06.520 --> 00:12.880 So if I move to my project tab, then assets and then prefabs folder, we can see we have multiple ground 00:12.880 --> 00:16.800 and we just drag it into our this grounds array. 00:16.840 --> 00:21.480 As you can see in the inspector underneath our ground spawner script. 00:21.480 --> 00:23.320 So we're going to choose a random one. 00:23.320 --> 00:24.960 And then we're going to spawn that. 00:24.960 --> 00:28.360 So let's open up our script quickly by double clicking on it. 00:28.640 --> 00:30.840 And let's move over to this function. 00:30.840 --> 00:34.080 As you can see over here we just pass uh sorry. 00:34.120 --> 00:39.000 We just pass right over here five, which basically means the sixth ground. 00:39.000 --> 00:43.080 So instead of spawning a specific one we're going to choose a random. 00:43.080 --> 00:46.840 So that's why we just created this private in index variable. 00:46.880 --> 00:52.800 As you can see over here it's just going to keep track of or it's just going to take care of that which 00:53.000 --> 00:55.600 uh which ground we just want to spawn. 00:55.600 --> 00:58.640 So that's why we just created this index parameter. 00:58.680 --> 00:59.760 Now what we're going to do. 00:59.760 --> 01:03.280 So before we spawn we're going to choose a random one. 01:03.480 --> 01:07.760 And in order to choose a random number one, we're going to use this random. 01:07.760 --> 01:10.560 So make sure you're just doing as I did over here. 01:10.560 --> 01:16.120 So we're going to use this random dot range function and this random dot range function in brackets. 01:16.160 --> 01:20.040 As a first argument it's going to take the minimum inclusive. 01:20.040 --> 01:22.480 So we're going to pass zero as a first. 01:22.520 --> 01:27.080 And we have to pass the max inclusive as you can see. 01:27.080 --> 01:31.160 So what we're going to pass right over here we're going to pass grounds dot. 01:31.520 --> 01:34.640 Firstly we're going to pass our array name which is grounds. 01:34.680 --> 01:36.680 So we're going to pass round array name. 01:36.680 --> 01:38.680 And then we're going to use dot length. 01:38.880 --> 01:41.280 And then close that up with some my colon. 01:41.280 --> 01:46.360 So let me explain what basically this grant grounds dot length means. 01:46.560 --> 01:50.520 So grant dot length basically means how many crown ground we have. 01:50.680 --> 02:00.600 So if we move over to unity and we can see underneath our spawner script we have 123456789 ten. 02:00.600 --> 02:02.840 So we have 11 grounds. 02:02.840 --> 02:07.810 So that's why this right over here grounds dot length just gonna be 11 right away. 02:08.090 --> 02:14.250 But this random dot range function, it's going to take a number between the zero and the ground dot 02:14.250 --> 02:15.370 length, which is 11. 02:15.370 --> 02:19.770 So it's going to take a random random number between 0 and 11. 02:19.770 --> 02:24.450 But it's not gonna include this ground dot length basically means interval. 02:24.450 --> 02:28.930 It's just gonna include zero and ten between 0 and 10. 02:29.010 --> 02:33.370 It's not gonna include or just gonna pick up 11 something like that. 02:33.370 --> 02:36.610 So this can be this random dot range function. 02:36.610 --> 02:39.930 Just gonna pick up a number between 0 and 11. 02:39.930 --> 02:42.770 But this function it's not gonna pick up 11. 02:42.770 --> 02:45.690 So but it will definitely gonna pick up ten. 02:45.690 --> 02:47.610 Or it can be something like nine. 02:47.650 --> 02:48.690 It can be four. 02:48.690 --> 02:51.410 So this gonna pick up a random number. 02:51.410 --> 02:52.730 So what we're gonna do. 02:52.730 --> 02:59.290 So after pick if this random dot range function just pick up random number something like let's suppose 02:59.290 --> 03:00.770 two and two. 03:00.810 --> 03:04.170 Then we're gonna store the result into this index parameter. 03:04.170 --> 03:06.570 So let's do so whatever the result is. 03:06.570 --> 03:12.290 Basically whatever this random dot range function picks up, we're going to store it into this index 03:12.290 --> 03:17.570 parameter or this index variable variable, which work like as a container you can say. 03:17.570 --> 03:19.450 So we're going to put it in this container. 03:19.450 --> 03:21.170 So in our case index. 03:21.170 --> 03:23.730 So we will set index equal to this. 03:24.010 --> 03:32.210 So this index can be 0123 or even 9 or 10 depending upon what this random dot range function pick ups. 03:32.210 --> 03:35.610 So let's suppose this random dot range range function. 03:35.610 --> 03:37.370 Just pick up something like six. 03:37.490 --> 03:40.090 Then this index is going to be six right away. 03:40.090 --> 03:45.250 Because as you can see we're just setting a index equal to random dot range. 03:45.410 --> 03:48.330 And now what we're going to do we're going to replace this five. 03:48.370 --> 03:51.570 So we're going to replace this five with our this index. 03:51.570 --> 03:53.290 So we're going to pass our index. 03:53.290 --> 03:59.890 And we do know this index can be a random number depending upon what this random dot range function 03:59.890 --> 04:00.490 pick up. 04:00.490 --> 04:04.010 So let's suppose this random dot range function pick up six. 04:04.010 --> 04:06.330 So this is just gonna be six right away. 04:06.330 --> 04:07.330 This index. 04:07.330 --> 04:10.370 So this index over here just became six. 04:10.370 --> 04:11.890 And we just assume it. 04:11.890 --> 04:13.690 So if we move to unity. 04:13.690 --> 04:20.690 So the six index we can see is the seventh ground underneath our ground spawner script as you can see. 04:20.850 --> 04:27.090 So index six is the seven ground basically means this ground number seven just gonna spawn from that 04:27.090 --> 04:27.810 position. 04:27.810 --> 04:29.170 But it can be random. 04:29.170 --> 04:36.250 We do know that we use this random dot range function in order to pick up a random number between zero 04:36.250 --> 04:37.010 and ground. 04:37.010 --> 04:38.810 Stalin means 11. 04:39.170 --> 04:40.850 So it can be random. 04:40.850 --> 04:42.570 So this index can be zero. 04:42.570 --> 04:47.290 So if it's zero then the first ground will be will be spawn from that position. 04:47.290 --> 04:51.210 And let's suppose this random dot range function pick up something like three. 04:51.210 --> 04:52.650 So this index gonna be three. 04:52.650 --> 04:55.090 So this over here will be three. 04:55.090 --> 04:59.690 So grounds three basically means the we can see is the fourth ground. 04:59.690 --> 05:01.010 So let's have a look on this. 05:01.010 --> 05:04.570 So we're going to press down Ctrl S in order to save our script. 05:04.570 --> 05:06.730 And let's move over to unity by now. 05:06.730 --> 05:07.970 And let's have a look. 05:07.970 --> 05:12.730 So we're gonna see a different ground just gonna spawn when we start our game. 05:12.890 --> 05:19.010 But it can be random depending upon what that random dot range function just pick up. 05:19.210 --> 05:23.570 So just wait for to compile and we're gonna play our game in order to check that. 05:24.130 --> 05:25.690 So just wait for to compile. 05:28.530 --> 05:30.970 Just wait for a little moment. 05:31.410 --> 05:37.650 And now what we're gonna do, we're going to click on this play button in the top in order to play our 05:37.650 --> 05:38.010 game. 05:38.050 --> 05:41.210 So let's click on this play button in the top to play our game. 05:41.330 --> 05:47.450 And right after the game start you will see a random or sorry a random ground just gonna spawn. 05:47.450 --> 05:48.570 So let's have a look. 05:48.770 --> 05:51.490 So as soon as the game started we can see. 05:51.530 --> 05:56.330 Now this, uh, I'm gonna click on this pause button in the top in order to pause my game. 05:56.570 --> 06:02.850 And I can see in our hierarchy ground underscore one clone just gets spawn. 06:02.850 --> 06:04.770 So this is the random one. 06:04.770 --> 06:08.570 So we're gonna get out of play mode by clicking on this play button in the top. 06:08.570 --> 06:11.410 And let's click the this play button in the top. 06:11.410 --> 06:13.090 One more time to play our game. 06:13.210 --> 06:18.940 And let's have a look if a random ground is just gonna be spawned. 06:18.940 --> 06:20.540 So let's have a look on this. 06:20.820 --> 06:23.340 So we we have seen the ground one. 06:23.340 --> 06:28.460 And let's take a look now so we can see I'm going to click on this pause button in the top to pause 06:28.460 --> 06:29.220 my game. 06:29.220 --> 06:33.060 And if I move over to hierarchy we can see ground underscore eight. 06:33.580 --> 06:34.940 Clone just gets spawn. 06:34.940 --> 06:40.180 Basically the ground number eight just gets spawn as soon as the game started. 06:40.180 --> 06:44.180 Because in the start of the game we just spawning the ground. 06:44.180 --> 06:50.580 So now let's get out of play mode and what we need to do now we need to change the spawn pose. 06:50.620 --> 06:54.900 Basically, we just want to spawn any ground from next position. 06:54.900 --> 07:00.500 And we do know, as you can see in every ground, we just created this next position. 07:00.500 --> 07:06.020 So that's why we just created an empty game object and we just name it Next Spawn pose. 07:06.020 --> 07:11.940 So what we're going to do now, we're going to spawn the next round, uh, ground from this position. 07:11.940 --> 07:15.220 In order to do that, make sure you assign it with something else. 07:15.220 --> 07:18.420 So we're going to take a look on this in the next chapter. 07:18.420 --> 07:22.100 Or you can say in the next lecture, we're gonna cover this up.
