WEBVTT 00:00.040 --> 00:03.120 Would be nice if we able to see our array. 00:03.520 --> 00:04.800 So what we will do? 00:04.840 --> 00:11.320 We're going to add a line render component in order to able able to see our array. 00:11.360 --> 00:12.360 So let's do that. 00:12.360 --> 00:15.120 We're going to select our player GameObject in the hierarchy. 00:15.120 --> 00:16.360 And let's click add. 00:16.480 --> 00:18.360 Let's click on this add component. 00:18.360 --> 00:21.560 And we're going to add a component called Line Renderer. 00:21.560 --> 00:24.560 So we're going to type the component name which is line renderer. 00:24.600 --> 00:27.680 As you can see, as soon as we type it gets pop up. 00:27.680 --> 00:30.080 And we're going to click there in order to attach. 00:30.240 --> 00:33.480 So make sure you just go to this line render component. 00:33.680 --> 00:36.000 Then materials you're going to find in the bottom. 00:36.000 --> 00:40.760 So scroll down a bit and materials and we can see it says none materials. 00:40.760 --> 00:43.880 So just click there and then select this default. 00:43.880 --> 00:48.160 Or you can simply type over here as well which is the default. 00:48.280 --> 00:49.440 And we're going to attach. 00:49.440 --> 00:54.200 And after doing that just move over to this position and then size. 00:54.200 --> 00:58.640 And we're going to make in the X something like five in order to be able to see. 00:58.640 --> 01:05.670 So as you can see we can see our array and uh, we can see or we can set the position as well. 01:05.670 --> 01:09.270 So I'm going to move over to this index and we can set the position. 01:09.270 --> 01:14.870 So I'm going to move over to in the Y a little bit up something like this. 01:15.830 --> 01:19.350 Sorry one and one we're going to do. 01:19.390 --> 01:25.590 As you can see now we are able to see our line renderer and we're going to adjust it. 01:25.590 --> 01:30.230 So uh so move over to this width and we're going to make it a little bit thickness. 01:30.230 --> 01:32.990 So we can simply select this red line. 01:32.990 --> 01:36.870 And we're gonna drag it down to make it a little bit thicker. 01:36.910 --> 01:38.470 Something much this. 01:38.470 --> 01:45.510 And I'm going to make it a little bit with a little bit up something around over here. 01:45.710 --> 01:49.990 And if you want to choose any color you can just move over to this color. 01:50.270 --> 01:51.750 Then you can choose the color. 01:51.750 --> 01:57.030 So in the right side click over here this and then click on this color. 01:57.030 --> 02:00.140 And you can choose the color that you want to choose. 02:00.140 --> 02:03.060 And I'm going to select this one and I'm going to delete it. 02:03.060 --> 02:06.300 So as soon as we delete we can see it's red. 02:06.300 --> 02:10.580 And you can choose the color which color you want to set with. 02:10.900 --> 02:15.980 But I'm gonna move I'm gonna basically what I'm gonna do, I'm gonna go with this red color. 02:16.220 --> 02:23.420 And now what we will do, we're gonna open up our player script in order to set this line render position 02:23.420 --> 02:26.900 as well as, uh, the where we just want to do that. 02:26.900 --> 02:30.700 So we also need to set this to be enable or disable. 02:30.740 --> 02:35.500 As you can see we can enable that as well as we can disable that. 02:35.500 --> 02:37.500 So let's open up our player script. 02:37.540 --> 02:42.660 And we need a reference of this line renderer component in order to set that. 02:42.660 --> 02:46.060 So let's open up our player script by double clicking on it. 02:46.060 --> 02:48.500 And we will move to the top of our class. 02:48.500 --> 02:51.300 And let's create another public variable. 02:51.460 --> 02:53.180 So let's click a public. 02:53.220 --> 02:56.260 And the component we're looking for is a line renderer. 02:56.260 --> 02:58.180 So we're going to type line renderer. 02:58.180 --> 03:04.210 And we can call it something like LR, short for line renderer, and then close that off with semicolon 03:04.210 --> 03:09.050 control for control S for saving your script and move over to unity. 03:10.810 --> 03:14.770 So underneath our player Skip we're going to see another fill. 03:14.770 --> 03:16.930 And that will be line renderer. 03:16.930 --> 03:23.410 So what we need to do there we need to basically drag the line renderer component in there. 03:23.410 --> 03:24.850 So we're going to have the reference. 03:24.850 --> 03:26.690 And then we can set the position. 03:27.170 --> 03:28.010 So just wait. 03:28.010 --> 03:31.210 As you can see LR and it says line renderer. 03:31.210 --> 03:33.330 So we're going to take our line render component. 03:33.330 --> 03:34.850 And we're going to drag it there. 03:34.850 --> 03:39.130 And we can see now we have a reference called player line Renderer. 03:39.130 --> 03:42.810 And now we are ready to set the position as well as the index. 03:42.810 --> 03:46.410 So let's open up our player script and what we will do. 03:46.450 --> 03:48.810 We're going to move over to this start function. 03:48.810 --> 03:52.170 And we do no start function get call in the start of the game. 03:52.170 --> 03:56.970 So in this start of the game what we want we just want to disable this renderer. 03:56.970 --> 04:03.720 So if we move to unity and then this line runner line renderer component and we can check it or uncheck 04:03.760 --> 04:08.600 it, check it, uncheck it basically means we just enabling or disabling it. 04:08.600 --> 04:13.000 So I'm gonna uh, what I'm gonna do, we're gonna do it with our script. 04:13.000 --> 04:15.520 So let's, let's move over to script. 04:15.520 --> 04:20.360 And then in the start of the game I just want to disable this blind renderer component. 04:20.360 --> 04:20.840 Why? 04:21.040 --> 04:23.480 Because we don't want this to be active. 04:23.520 --> 04:29.240 But once our player GameObject shoot out a ray something, once we click left mouse button, then we're 04:29.240 --> 04:31.560 gonna enable this line renderer. 04:31.560 --> 04:33.240 So basically that is the thing. 04:33.240 --> 04:37.640 So let's go to script and we're going to say line renderer and dot. 04:37.680 --> 04:41.160 We're going to use this enable parameter in order to set that. 04:41.160 --> 04:43.400 And we're going to set equal to false. 04:43.400 --> 04:48.520 False basically means we just disabling or if you pass through means enabling. 04:48.520 --> 04:51.840 So we just moving over to this line renderer component. 04:51.840 --> 04:55.400 And then we just disabling it in the start of the game. 04:55.400 --> 04:59.200 But once we click left mouse button then we need to enable this. 04:59.200 --> 05:00.800 So let's go to script now. 05:00.800 --> 05:02.120 And why are we doing. 05:02.200 --> 05:06.520 We just uh doing over here in shoot function as you can see. 05:06.520 --> 05:08.320 So we're going to do it over here. 05:09.480 --> 05:14.880 Uh, so uh, instead of using this shoot function we're going to use AI enumerator. 05:14.880 --> 05:15.320 Why? 05:15.600 --> 05:22.440 Uh, basically we want to enable this blind runner component a few second or a pretty short time, and 05:22.440 --> 05:24.800 then we're gonna disable that right away. 05:24.840 --> 05:27.000 We're going to enable for pretty short time. 05:27.000 --> 05:30.040 And after that we're gonna disable right away. 05:30.320 --> 05:37.400 Uh, after that or a short period of time, something like a millisecond or even we're gonna enable 05:37.400 --> 05:41.960 that blind runner point 5 or 0.2 second for a short moment. 05:41.960 --> 05:43.960 And after that we're gonna disable that. 05:43.960 --> 05:46.560 So that's why we're going to use this AI enumerator. 05:46.720 --> 05:49.440 So we need to get rid of this, uh, void. 05:49.600 --> 05:52.280 And we have to use this AI enumerator. 05:52.280 --> 05:58.630 So before you use that, make sure you just go to the top of your class and then include this name namespace. 05:58.670 --> 06:05.550 It's called using sorry as using a system dot collection. 06:05.830 --> 06:11.470 So you need to use this system dot collection in top of your, uh, unity class. 06:11.470 --> 06:17.830 So make sure you just go to top of your class and then use this namespace call using system dot collection. 06:17.830 --> 06:21.790 And it's gonna allow us to use I enumerator function. 06:21.790 --> 06:23.230 So we're going to do it over here. 06:23.230 --> 06:25.510 So we're going to get of uh our void. 06:25.510 --> 06:27.870 And we're going to type this I enumerator. 06:27.910 --> 06:29.510 Now we able to see. 06:29.510 --> 06:32.510 So why we using this I enumerator function. 06:32.510 --> 06:38.030 Because we're gonna wait for some moment and after that we're gonna disable that array right away. 06:38.030 --> 06:45.150 Or that line renderer for enabling for, uh, for enabling a few moments or few seconds. 06:45.150 --> 06:46.990 And after that, we're gonna disable. 06:46.990 --> 06:51.830 So this enumerator function is allow us to delay some line of code. 06:51.830 --> 06:59.020 Or if you want to do a, uh, if you want to do some specific things after some certain period of time, 06:59.300 --> 07:05.180 then you can use this AI enumerator function in order to do that and make sure why're you calling your 07:05.180 --> 07:05.860 function? 07:05.860 --> 07:08.100 You need to call it in a different way. 07:08.100 --> 07:11.980 So we just simply take the shift function or the name of the function. 07:11.980 --> 07:17.780 As you can see, instead of using that what we have to do, we need to use this startcoroutine. 07:17.820 --> 07:22.140 It's kind of a bit weird, but you have to use that and then make first bracket. 07:22.140 --> 07:26.660 And in this bracket you need to, uh, put the function that you want to call. 07:26.660 --> 07:28.420 So we're going to call this function. 07:28.420 --> 07:31.900 So that's why in this brackets we need to type the function name. 07:31.900 --> 07:37.580 So in our case shoot and make sure you make this first bracket because that itself a function. 07:37.580 --> 07:39.580 And then close that up with semicolon. 07:39.580 --> 07:42.500 So you need to call the function in this startcoroutine. 07:42.500 --> 07:45.100 It's kind of a bit weird but we have to do it. 07:45.100 --> 07:51.140 So we're using this I inner I enumerator function in order to delay some line of code. 07:51.380 --> 07:54.970 So what we're going to do now we're going to use this alert. 07:55.090 --> 08:01.370 So once we're calling the shoot function that what we want to what we have to do, we need to enable 08:01.370 --> 08:02.690 that this way. 08:02.690 --> 08:07.330 So that's why we will go to LR basically line runner line renderer. 08:07.330 --> 08:11.690 And then we're going to use this enable function in order to enable that. 08:11.690 --> 08:13.930 And we're going to set equal to true. 08:13.930 --> 08:18.890 Basically we just enable and after short period of time we're going to disable that. 08:18.890 --> 08:25.050 So that's why uh we're going to use this l return new wait for second. 08:25.050 --> 08:30.970 So you can use this new wait four seconds wait four seconds and then make first bracket. 08:31.010 --> 08:32.890 Then close that output semicolon. 08:33.050 --> 08:35.050 So we have to use this. 08:35.090 --> 08:40.010 It's called l return new wait for second so you can put the time over here. 08:40.010 --> 08:41.730 And after that what you gonna do. 08:41.730 --> 08:43.290 It's going to print out. 08:43.290 --> 08:50.530 So let's suppose uh we're going to say something like after 0.12 second or a pretty short period, uh, 08:50.530 --> 08:56.760 time, you can simply say, and after this amount of time that what we have to do, we need to disable 08:56.800 --> 08:59.440 our line renderer right away. 08:59.440 --> 09:04.600 So that's why we will go to LR, then enable and we're going to set equal to false. 09:04.600 --> 09:06.440 Basically we just disabling this. 09:06.440 --> 09:08.200 Firstly we age enabling. 09:08.240 --> 09:12.160 As you can see we just going over to this line renderer component. 09:12.160 --> 09:13.720 And then we just enabling. 09:13.760 --> 09:19.640 And after this period of time here return you wait for second this period of time what we're doing we're 09:19.640 --> 09:23.600 just going over to LR basically this line renderer component. 09:23.600 --> 09:28.640 And then we just disabling it after just enabling this period of time. 09:28.640 --> 09:32.360 And we're going to press down Ctrl S in order to save our script. 09:32.360 --> 09:34.200 And now let's move over to unity. 09:34.240 --> 09:38.280 Basically we want to see if it's perfectly working or not. 09:38.280 --> 09:40.760 So in this start of the game we just disabling. 09:40.800 --> 09:46.680 And once we click the left mouse button then we just enable link for short period of time. 09:46.680 --> 09:47.760 So let's have a look. 09:47.760 --> 09:51.320 So I'm going to click on this play button in the top in order to check it. 09:51.320 --> 09:57.270 So I'm going to click the left mouse button in order to enabling that line renderer. 09:58.510 --> 10:00.630 So I'm going to click the left mouse button. 10:01.390 --> 10:07.790 As you can see, as soon as we click, it just gets active and some period of time it just gets disabled. 10:07.830 --> 10:11.030 As you can see in the, in uh, in the scene view. 10:11.030 --> 10:12.470 So we just enabling that. 10:12.470 --> 10:18.870 And after some period of time we can see it's just getting disabled automatically because after that 10:19.110 --> 10:21.030 0.12 seconds which is disabling. 10:21.030 --> 10:22.630 So I'm going to get out of play mode. 10:22.630 --> 10:25.030 And now let's move over to script. 10:25.030 --> 10:26.310 And what we have to do. 10:26.350 --> 10:33.190 We need to set the position so we can only see this line just getting over here active and just it's 10:33.190 --> 10:39.710 getting the active, uh, after that amount of time and it just happening over here, instead of doing 10:39.750 --> 10:42.870 that, what we're going to do, we're going to set the line renderer. 10:42.870 --> 10:45.470 So we're going to store the first position over here. 10:45.590 --> 10:50.110 And we're going to store the second position the ray hit width. 10:50.110 --> 10:53.820 So let's suppose the ray hit with awe with this anime game object. 10:53.820 --> 11:00.380 Then we're going to set the second position of the line renderer component where the ray hit width. 11:00.380 --> 11:02.780 So let's go to script in order to do that. 11:02.780 --> 11:04.020 So let's go to script. 11:04.220 --> 11:06.780 And over here we're doing as you can see. 11:06.820 --> 11:12.140 But before we do after enabling our line renderer component, we're going to set the position. 11:12.140 --> 11:17.460 So we have to use this alert dot set position function and set position. 11:17.460 --> 11:19.580 And first make this first bracket. 11:19.620 --> 11:21.540 Then close it up with semicolon. 11:22.580 --> 11:25.980 So this alert dot set position as a first argument. 11:25.980 --> 11:28.020 Or it's going to take the index. 11:28.060 --> 11:33.580 So we're going to pass zero zero basically means we just gonna refer the first position. 11:33.820 --> 11:39.500 So we're going to store this position where the where we start our ray. 11:39.500 --> 11:44.180 So we're gonna we shooting out our ray from this shoot point position. 11:44.180 --> 11:49.460 So that's why we're going to store the first position in this index which is zero as you can see. 11:49.620 --> 11:55.250 So the position we're going to pass through points position or where from which just shoot shooting 11:55.250 --> 11:55.930 out the ray. 11:56.170 --> 12:01.130 We definitely gonna shoot out the ray from this position which is our should point out position. 12:01.130 --> 12:06.570 So we're going to pass our shoot point position or the first position into this zero index. 12:06.570 --> 12:15.090 So the position is just going to be shoot point shoot point dot position and shoot point dot position 12:15.090 --> 12:17.210 basically means where we shooting out the ray. 12:17.330 --> 12:20.850 So we're just shooting out the ray from this shoot point dot position. 12:20.850 --> 12:24.970 So that's why we just are taking our shoot point out position. 12:25.370 --> 12:28.130 And we're storing in this zero index. 12:28.130 --> 12:32.170 And we also need to set the second position as well. 12:32.570 --> 12:34.170 So we're going to do it over here. 12:34.170 --> 12:35.730 As you can see what we're doing. 12:35.730 --> 12:40.090 We're just printing out a message in the console says takes damage. 12:40.090 --> 12:47.610 So we also want to set the second position of that render line renderer component with our second index. 12:47.610 --> 12:49.970 So we're going to do it over here. 12:49.970 --> 12:57.410 So LR we're going to use this LR set position function in order to set the position and then make first 12:57.410 --> 12:58.090 bracket. 12:58.090 --> 12:59.850 So we're going to pass our index. 13:00.170 --> 13:03.650 Now we're going to store our second position the ray hit width. 13:03.650 --> 13:06.530 So the ray is just going to hit with this enemy game object. 13:06.530 --> 13:12.690 So where hit width we can store that position in our one index. 13:12.690 --> 13:16.010 So we just store it the first position in this zero index. 13:16.010 --> 13:19.410 Now we're going to store our second position in the one index. 13:19.410 --> 13:23.050 So firstly we're going to we have to type the index and then comma. 13:23.050 --> 13:29.970 And we have to pass the position which position we want to store into this index. 13:29.970 --> 13:36.290 So we're going to pass our hit info hit info dot point and then close that off with semicolon. 13:36.290 --> 13:41.130 So hit info dot point basically means the ray hit with the position. 13:41.130 --> 13:43.930 So the ray gonna hit with this enemy game object. 13:43.930 --> 13:51.360 So so the hit point dot hit info dot point basically means the position the ray collided with. 13:51.360 --> 13:54.640 So the ray is gonna collide with this, uh, enemy game object. 13:54.640 --> 14:02.040 So we're storing that point or or where the ray hit with we just storing that position into this one 14:02.040 --> 14:03.760 index, as you can see. 14:03.920 --> 14:07.240 So we're going to press on control S in order to save our script. 14:07.240 --> 14:08.720 And let's move to unity. 14:09.760 --> 14:14.400 So we firstly we're storing our first position into this zero index. 14:14.400 --> 14:21.520 And once the ray hit with then we're storing that uh, that uh or the second position which is storing 14:21.520 --> 14:24.080 in this one index as you can see. 14:24.200 --> 14:32.680 So let's move to unity now and let's click on this play button in the top in order to is able to see 14:32.680 --> 14:33.120 that. 14:33.360 --> 14:38.520 So once we click the left mouse button you will able to see the ray because we're storing the first 14:38.520 --> 14:40.800 position into zero index. 14:40.800 --> 14:43.600 So I'm going to click left mouse left mouse button. 14:43.600 --> 14:47.120 As you can see as soon as we click we can see the ray. 14:47.160 --> 14:51.670 Just uh, getting active with this or where the Ray hit with. 14:51.710 --> 14:53.790 We're just getting to that point as well. 14:53.790 --> 14:59.670 And I'm going to make the player speed a little bit slow, something like I'm gonna make, uh, in order 14:59.670 --> 15:01.470 to check something like 0.5. 15:01.630 --> 15:05.110 And let's click on this play button in the top in order to check it. 15:05.110 --> 15:07.270 And I'm going to check one more time. 15:07.270 --> 15:08.870 So I'm going to click left mouse button. 15:08.870 --> 15:15.390 And we will see that, uh, the ray just gonna active or enabled for a few minutes. 15:15.390 --> 15:17.990 And then it's gonna disable as you can see. 15:18.030 --> 15:23.390 And we can see the ray just getting shoot it, shoot it out from that shoot point dot position. 15:23.390 --> 15:26.110 And the ray just collided with this enemy game object. 15:26.110 --> 15:30.630 So that's why the second position, uh, we just store it in the one index. 15:30.630 --> 15:32.110 So I'm going to get out of play mode. 15:32.110 --> 15:35.550 And let's suppose this enemy game object is not there. 15:35.550 --> 15:41.550 So if I select my enemy GameObject in the hierarchy and I just disable it right away, go over to Inspector 15:41.550 --> 15:44.470 and you can just uncheck that in order to disable. 15:44.590 --> 15:51.420 And now if we click on this play button you will will not able to see the ray because the ray not are 15:51.420 --> 15:54.300 not getting collided with that enemy game object. 15:54.300 --> 15:56.380 So that's why we're not gonna able to see. 15:56.660 --> 16:01.980 So if I just click the left mouse button, as you can see, it's just moving over to negative direction 16:02.140 --> 16:04.620 or it's just shooting out from this position. 16:04.620 --> 16:06.140 But we don't want to do that. 16:06.140 --> 16:08.540 So I'm going to click on I'm gonna pause my game. 16:08.540 --> 16:12.540 So what we want to do let's suppose if there is no enemy. 16:12.540 --> 16:19.620 So we still want to see that line renderer or that ray and it's gonna shoot out with nothing and nothing. 16:19.620 --> 16:24.300 So we just want to, uh, want to see or want to set a event. 16:24.340 --> 16:26.220 It's just shooting nothing. 16:26.220 --> 16:28.820 So we want to see in the right direction. 16:28.820 --> 16:30.460 So let's get out of play mode. 16:30.460 --> 16:36.740 So the if the ray is not colliding with that enemy game object, then we still want to see our ray. 16:36.740 --> 16:38.180 So let's go to script. 16:38.180 --> 16:39.820 And we're doing it over here. 16:39.820 --> 16:46.420 As you can see if hit info basically means true means the ray is really colliding with that enemy game 16:46.490 --> 16:47.010 object. 16:47.010 --> 16:53.770 And let's suppose the array is not colliding with any game object, but we still want to see that line 16:53.770 --> 16:59.930 renderer, and we're going to set the line renderer as the this as the length of the array. 16:59.930 --> 17:02.330 So that's why we're going to use this else condition. 17:02.370 --> 17:06.050 Else the array is not colliding with our enemy game object. 17:06.050 --> 17:12.210 But we still want to set the position of that renderer component with the distance or the length of 17:12.250 --> 17:12.810 the array. 17:13.410 --> 17:15.730 So that's why we're going to use this else condition. 17:15.730 --> 17:19.250 And we're going to check we're going to set the position which is LR dot position. 17:19.250 --> 17:24.810 We need to use this function in order to set the position and close that off with semicolon. 17:24.810 --> 17:27.570 So the array will not collide with anything. 17:27.570 --> 17:31.370 So we're going to store the position in this one index comma. 17:31.530 --> 17:35.290 And it's going to take the position where we want to set a set. 17:35.330 --> 17:39.210 We do know that we're not going to collide with any enemy game object. 17:39.210 --> 17:41.610 So we are gonna shoot in nothing. 17:42.210 --> 17:44.290 But we still want to say see. 17:44.490 --> 17:48.160 So that's why we're going to use this transformer, right? 17:48.200 --> 17:49.120 Transform, right. 17:49.480 --> 17:49.760 Dot. 17:49.800 --> 17:50.080 Right. 17:50.080 --> 17:52.920 Basically means, uh, in which direction we're shooting. 17:53.680 --> 17:55.760 So we're just shooting in the right direction. 17:55.760 --> 17:57.520 So that's why transport dot right. 17:57.560 --> 17:59.280 Basically means the direction. 17:59.280 --> 18:03.480 And we're going to multiply that direction with our length of the ray. 18:03.600 --> 18:09.440 So we're going to multiply length or sorry we're going to use this distance basically distance. 18:09.440 --> 18:11.920 Uh by default we set in Inspector ten. 18:12.080 --> 18:14.600 And this is basically the length of the ray. 18:14.600 --> 18:19.400 So we basically multiplying our uh direction with our distance. 18:19.400 --> 18:25.080 So we're going to able to see the ray with the distance or the length of the ray which is ten by default. 18:25.080 --> 18:26.640 We set in inspector. 18:26.640 --> 18:30.560 And on top of that we're going to basically, uh, this will be direction. 18:30.560 --> 18:34.680 So we're going to we add this, uh transform dot. 18:34.720 --> 18:35.240 Right. 18:35.240 --> 18:39.240 So we're going to add shoot point shoot point dot position. 18:39.240 --> 18:41.280 And on top of that we're going to add this. 18:41.280 --> 18:45.470 So shoot point dot position basically means where we shoot it out the way. 18:45.470 --> 18:49.830 And on top of that, we're just adding our length of the ray, as you can see. 18:49.870 --> 18:55.990 And we also taking the direction and we multiplying with this distance basically means the ray length 18:56.030 --> 18:57.230 length of the ray. 18:57.230 --> 19:00.590 So we the so this just going to be like this. 19:00.630 --> 19:04.270 And we're just adding top of our shoot point top position. 19:04.270 --> 19:09.510 So point dot position means where we shoot it out the ray and top of that we just adding the length 19:09.510 --> 19:13.390 of the ray as you can see, because it's gonna shoot with nothing. 19:13.390 --> 19:17.870 But we still want to say see the ray as the length of our ray. 19:17.870 --> 19:18.910 So that's why we type. 19:18.950 --> 19:21.470 Firstly we take taking the direction. 19:21.470 --> 19:24.750 So we're going to shoot out in the right direction the ray. 19:25.070 --> 19:27.550 And we just multiplying with our distance. 19:27.550 --> 19:29.870 So we're gonna able to see our ray. 19:30.230 --> 19:36.790 So this is the second position where uh when we're shooting in nothing which is storing this position 19:36.990 --> 19:42.790 into this one index once the ray is not colliding with any enemy game object. 19:42.790 --> 19:46.220 So let's press down control S in order to save our skip. 19:46.220 --> 19:48.220 And now let's move over to unity. 19:48.220 --> 19:55.020 But if you still are a little bit confused, then of course I will give a another video in the resources 19:55.020 --> 20:01.060 about shooting out prey, and you can check that out if you just want to learn it more. 20:01.100 --> 20:06.420 Firstly, what we're doing, we just taking our position from where we shoot it out, the way we just 20:06.420 --> 20:11.940 shoot point dot position and on top of that we just taking the direction and we multiplying with the 20:11.940 --> 20:14.140 length of the ray, which is distance. 20:14.140 --> 20:20.380 So uh, so we're going to able to see our line renderer with the length of the ray which is ten. 20:20.380 --> 20:26.820 By default we set and we just storing the second position for when we shoot in nothing into this one 20:26.820 --> 20:28.340 index, as you can see. 20:28.380 --> 20:32.740 And the first position we just store it in this zero index. 20:33.060 --> 20:36.860 So we're going to press down Ctrl S to save our script and move to unity. 20:36.860 --> 20:39.100 And let's click on this play button by now. 20:39.220 --> 20:43.450 And you will able to see that as well. 20:44.170 --> 20:49.410 So just wait for to compile and if we should nothing. 20:49.410 --> 20:50.810 And then click left mouse button. 20:50.810 --> 20:54.090 And now we are able to see our array. 20:54.130 --> 20:55.250 As you can see. 20:55.290 --> 21:00.210 And after 0.12 second it's just getting disabled automatically. 21:01.050 --> 21:02.490 Let's get auto play mode. 21:02.490 --> 21:03.730 And let me explain. 21:03.730 --> 21:10.690 If we move to script, as you can see firstly we enabling our line renderer and then after we just disabling. 21:10.690 --> 21:14.170 So we use this else return new wait for second. 21:14.170 --> 21:20.410 And you have to put in this brackets the time in which uh after this amount of time it's going to be 21:20.410 --> 21:21.090 disabled. 21:21.130 --> 21:27.050 As you can see, after enabling and after this amount of time, we just disabling our line renderer 21:27.050 --> 21:33.370 component LR dot enable equal to false basically means we just disabling and make sure you just call. 21:33.610 --> 21:39.250 Basically we use this eye enumerator should function in order to delay some line of code. 21:39.250 --> 21:40.810 So we need to use that. 21:40.810 --> 21:48.010 So if you just want to delay any some certain things after some period of time, then you can use this 21:48.050 --> 21:49.610 AI enumerator function. 21:49.610 --> 21:55.850 In order to do that, instead of using void, we need to use this AI enumerator and you have to name 21:55.850 --> 21:57.930 the function what we want to name it. 21:57.930 --> 22:03.450 But before you include this function, make sure you just go to the top of your class and include this 22:03.450 --> 22:06.410 namespace called using system dot collection. 22:06.410 --> 22:11.530 And it's gonna allow us in order to use our enumerator function. 22:11.530 --> 22:14.050 And you need to call function in a weird way. 22:14.090 --> 22:18.490 Firstly you need to use this startcoroutine and you need to make this brackets. 22:18.490 --> 22:21.810 And in this bracket you need to call the function. 22:21.810 --> 22:24.010 In our case shoot as you can see. 22:24.010 --> 22:27.170 So we're using this Startcoroutine and then shoot function. 22:27.170 --> 22:31.650 And when we doing once we click our left mouse button as you can see. 22:31.650 --> 22:33.490 So basically this is the cool thing. 22:33.730 --> 22:39.170 And once once we shooting in nothing then we just taking our second position. 22:39.170 --> 22:45.960 And we storing in this one More in this index, which is one or which is storing our second position 22:45.960 --> 22:47.360 in this bond index. 22:47.360 --> 22:53.600 But once the ray collides with that anime game object and hitpoint dot hit info dot point basically 22:53.600 --> 22:56.240 means the ray hit with that enemy game object. 22:56.240 --> 23:02.440 So we're just taking that position where the where our Ray hit with anime game object, we're just taking 23:02.440 --> 23:05.840 that position and we're storing in this one index. 23:05.840 --> 23:14.680 But once our ray is shooting nothing, then we just are taking our position with where we just were 23:14.680 --> 23:20.480 shoot it out and we just taking the length of the ray and we're storing that whole thing or that position 23:20.480 --> 23:22.200 in this one index. 23:22.200 --> 23:23.520 As you can see. 23:23.520 --> 23:29.920 I hope you get the idea that how you can do it and make sure you just press down Ctrl s in order to 23:29.960 --> 23:30.360 save. 23:30.400 --> 23:33.760 And let's suppose we just want to enable our enemy game object. 23:33.760 --> 23:38.360 And I'm going to make our a our player jump a little bit high. 23:38.440 --> 23:41.110 So I'm going to select my player game object in the hierarchy. 23:41.350 --> 23:43.870 And I'm going to make the player script. 23:43.870 --> 23:49.150 Or let's move to player script and I'm going to make the jump height something like 20 in order to check 23:49.190 --> 23:50.190 or 25. 23:50.310 --> 23:53.350 And I'm going to enable my enemy GameObject for now. 23:53.350 --> 23:57.630 So let's select the enemy GameObject in the hierarchy and let's enable that. 23:58.310 --> 24:00.350 And we will able to see by now. 24:00.350 --> 24:03.150 So let's click on this play button in the top. 24:03.150 --> 24:08.710 So once we shooting nothing the ray will still we will able to see our ray. 24:08.870 --> 24:13.350 But once the ray collide with this enemy GameObject you will see the ray will be set. 24:13.390 --> 24:20.070 Position the second position with this enemy GameObject where the ray collided with this enemy GameObject 24:20.510 --> 24:21.590 and we can see. 24:21.630 --> 24:29.470 And once we jump and shoot shoots in nothing, we still are gonna able to see our Ray or we just setting 24:29.470 --> 24:30.710 the line renderer. 24:31.030 --> 24:35.350 Uh, in our in nothing as you can see. 24:35.670 --> 24:40.660 And our background seems a little bit weird, basically, uh, the parallax effect. 24:40.700 --> 24:41.500 Then you can. 24:41.700 --> 24:44.460 Then you have to adjust the perfect position. 24:45.140 --> 24:47.060 And I'm gonna get out of play mode. 24:47.260 --> 24:50.780 And we will select our player GameObject in the hierarchy. 24:50.780 --> 24:54.260 Let's go to overrides and then click on this Apply All. 24:54.420 --> 24:58.660 And I want to move this line render component in my player GameObject. 24:58.660 --> 25:03.340 In the Inspector, I just want to move it up so we cannot do it over here. 25:03.340 --> 25:06.180 Instead we need to open that in prefab mode. 25:06.180 --> 25:09.020 So I'm going to click on this open in the Inspector. 25:09.380 --> 25:13.900 And now what I'm going to do I'm going to right click on this line renderer component. 25:13.900 --> 25:16.060 And I'm going to click on this pop up. 25:16.100 --> 25:19.540 In order to move this component in top of this player, skip. 25:19.540 --> 25:24.900 And if you just want to move it a little bit up, then you can just right click and then click on this 25:24.940 --> 25:25.540 move up. 25:25.540 --> 25:29.700 So it's gonna move up that component in top of the inspector. 25:29.700 --> 25:31.660 And you're gonna able to see that. 25:31.660 --> 25:34.380 And if you just want to go back in normal mode. 25:34.380 --> 25:36.700 So in hierarchy you can see back arrow. 25:36.700 --> 25:39.220 So just click there in order to go back.
