WEBVTT 00:00.040 --> 00:01.880 We want to shoot out the arrow. 00:02.080 --> 00:06.080 So before we shoot out the arrow, we need to create our arrow. 00:06.240 --> 00:12.840 So let's head over to our project app assets and then sprites folder, and I will head over to my anime 00:12.880 --> 00:14.400 folder one folder. 00:14.400 --> 00:18.040 As you can see I have my arrow sprite right over here. 00:18.480 --> 00:19.640 So let's select that. 00:20.000 --> 00:23.480 So we're going to click on this arrow and we will select this one. 00:23.520 --> 00:26.720 Let's drag it over to this in view or into this hierarchy. 00:26.920 --> 00:31.440 So as you can see as soon as we drag it it seems a lot more small. 00:31.440 --> 00:34.320 So we need to make make it a little bit bigger. 00:34.320 --> 00:38.200 So we will select the sprite sprite from that folder. 00:38.200 --> 00:41.080 Then go over to Inspector and pixel per unit. 00:41.080 --> 00:46.400 We're gonna make it less so in order to make this sprite large in size. 00:46.400 --> 00:50.840 So we need to make this pixel per unit a less number and filter mode. 00:50.880 --> 00:53.760 We're going to choose point of filter to get rid of blurry. 00:53.800 --> 00:57.160 And let's click on this apply button in the bottom right. 00:57.160 --> 01:01.020 And now as soon as we have done it we can see our arrow? 01:01.500 --> 01:05.220 Uh, but it's, uh, facing to the right direction. 01:05.220 --> 01:09.620 So we want to flip this arrow horizontally in the left direction. 01:09.620 --> 01:11.460 So we will select our arrow. 01:11.500 --> 01:14.260 Let's go over to Sprite Renderer in Inspector. 01:14.260 --> 01:18.300 And we're going to check the flip in the X basically horizontally. 01:18.460 --> 01:22.580 And let's call it arrow instead of calling arrow underscore zero. 01:22.780 --> 01:24.460 So let's call it arrow. 01:24.660 --> 01:26.540 So we will add some component. 01:26.540 --> 01:30.260 First thing I'm going to add a rigid body 2D for gravity. 01:30.260 --> 01:32.420 And I'm going to set the gravity equal to zero. 01:32.420 --> 01:34.700 So it's not going to fall down at all. 01:34.860 --> 01:37.020 Or we can just set it to kinematic. 01:37.020 --> 01:39.060 So let's click on this add component. 01:39.060 --> 01:41.740 And let's find rigid body 2D by typing. 01:41.780 --> 01:43.260 And let's attach that. 01:43.460 --> 01:47.980 And I'm gonna set this body type to kinematic and collision detection. 01:47.980 --> 01:51.420 We're going to choose continuous and interpolate. 01:51.420 --> 01:54.740 We can choose interpolate to making a little bit more. 01:54.900 --> 01:59.140 And let's let's add another component for collision detection. 01:59.140 --> 02:01.600 So let's click on this add component. 02:01.600 --> 02:03.960 And we're going to add a box Collider 2D. 02:03.960 --> 02:05.400 And let's attach that. 02:05.640 --> 02:09.040 And let's click on this Edit Collider right over here. 02:09.040 --> 02:12.880 And let's edit the collider as the size of our arrow. 02:13.680 --> 02:16.840 Sorry let's click on this Edit Collider. 02:17.120 --> 02:20.000 And this seems pretty much fine. 02:20.000 --> 02:24.880 And once you are satisfied then you are good to go. 02:25.240 --> 02:29.840 And now what we want to do, we want to assign this arrow as a arrow tag. 02:29.840 --> 02:32.200 So we will choose our arrow in the hierarchy. 02:32.240 --> 02:34.440 Let's go over to Inspector and Tag. 02:34.480 --> 02:36.520 As you can see it says tag. 02:36.520 --> 02:37.520 So let's click there. 02:37.520 --> 02:39.000 Let's click on Add tag. 02:39.160 --> 02:44.040 Then click on this plus icon, name the tag whatever you want and then click on save. 02:44.080 --> 02:48.600 I already created a arrow tag as you can notice right over here. 02:48.600 --> 02:51.400 So I'm going to choose my arrow one more time in the hierarchy. 02:51.520 --> 02:54.800 Go over to Inspector and Tag which says untagged. 02:54.800 --> 02:56.880 We're gonna assign with our arrow. 02:56.920 --> 03:01.980 Now we assign it this arrow as arrow tag, As you can see in the inspector. 03:02.580 --> 03:04.100 So I hope you get the idea. 03:04.300 --> 03:06.900 Now let's turn this arrow into a prefab. 03:06.900 --> 03:11.340 So we will have the copy, and we will spawn it via when we need it. 03:11.340 --> 03:17.740 So let's select our arrow in the hierarchy, and let's drag it over to this prefabs folder in our project 03:17.780 --> 03:20.100 tab inside this assets folder. 03:20.140 --> 03:22.060 Now we turn it into a prefab. 03:22.060 --> 03:26.860 So let's select the arrow in the hierarchy and let's delete it from the scene view now. 03:26.860 --> 03:34.340 And we want to spawn it once this enemy GameObject just shooting out basically playing that arrow fire 03:34.380 --> 03:35.460 animation clip. 03:35.460 --> 03:38.340 So we will open up our enemy one script. 03:38.340 --> 03:40.020 So let's double click on it. 03:40.220 --> 03:44.860 And so first thing what we need we need a reference of that arrow prefab. 03:45.020 --> 03:49.380 So if I move over to my project tab assets and then prefabs folder. 03:49.420 --> 03:52.580 As you can see we have the arrow right over here. 03:52.580 --> 03:55.460 And this arrow itself a whole game object. 03:55.460 --> 03:56.900 So we need a reference. 03:56.900 --> 03:59.220 And after that we can just shoot out that. 03:59.220 --> 04:05.840 So let's go over to our anime one and let's go to top of our class and let's make it over here. 04:05.840 --> 04:08.240 So let's make a another serialized field. 04:08.880 --> 04:11.480 Uh, private, uh, private. 04:11.480 --> 04:12.120 Sorry. 04:12.160 --> 04:15.840 This will be private, and the component will look sorry. 04:15.880 --> 04:16.840 Not component. 04:17.040 --> 04:19.360 Are we looking for our game object? 04:19.360 --> 04:21.160 So we're going to type game object. 04:21.160 --> 04:23.040 And the game object is arrow. 04:23.040 --> 04:26.200 So we can simply call it something like arrow prefab. 04:26.320 --> 04:28.160 So let's call it arrow prefab. 04:28.400 --> 04:31.680 And let's close that off with semicolon. 04:31.680 --> 04:36.600 And make sure you press down Ctrl S to save your script and then move over to unity. 04:36.760 --> 04:41.840 So underneath our anime one script a field just gonna pop up says Arrow Prefab. 04:41.840 --> 04:47.480 So what we need to do there, we basically have to select our arrow prefab from this prefab folder, 04:47.480 --> 04:49.760 and we need to drag it over to that slot. 04:49.760 --> 04:51.360 So we will have the reference. 04:51.360 --> 04:54.320 And then we can just spawn it when we need it. 04:54.320 --> 04:57.080 So let's select our anime one in the hierarchy. 04:57.200 --> 05:03.620 As you can see underneath our enemy one we can see arrow prefab and it says non-game object. 05:03.620 --> 05:08.700 So let's choose our arrow prefab from that prefabs folder and let's drag it over here. 05:08.740 --> 05:14.500 Now we can see we have the arrow prefab as you can notice, and we are ready to spawn it. 05:14.500 --> 05:17.620 So let's open up our enemy one script one more time. 05:17.620 --> 05:22.220 And for that we will make a function to spawn our arrow. 05:22.220 --> 05:24.860 So let's make it somewhere around here. 05:25.060 --> 05:29.660 And we're going to make this function public since we're going to call this function through animation 05:29.700 --> 05:30.180 event. 05:30.180 --> 05:31.380 So let me explain. 05:31.380 --> 05:36.820 If I move over to unity, select this anime one and then move over to animation tab. 05:36.820 --> 05:43.020 And then click over here and then choose this arrow one sorry enemy one underscore arrow fire animation 05:43.020 --> 05:43.580 clip. 05:43.580 --> 05:48.420 So we want to call the function somewhere over here as you can see. 05:48.420 --> 05:51.580 So this is just going to be perfect time in order to call. 05:51.580 --> 05:55.140 So we will call the function here through animation. 05:55.140 --> 06:00.920 So that's why we need to mark that function as public as we have done inside this player game. 06:00.960 --> 06:01.880 Object Attack. 06:02.280 --> 06:08.280 Uh, I hope you get the idea that how we can do it, uh, we have done the same thing inside this player 06:08.320 --> 06:12.840 game object once we basically calling the attack function. 06:12.840 --> 06:19.560 So let's move over to our script and let's make this function public and, uh, public void. 06:19.560 --> 06:23.000 And we can call this function to something like spawn arrow. 06:23.160 --> 06:25.520 So let's call it spawn arrow. 06:25.720 --> 06:28.720 And let's make first bracket and some curly brackets. 06:28.880 --> 06:36.320 And this function over here as if to spawn our arrow, we do know that we need to use this instantiate 06:36.320 --> 06:36.960 function. 06:36.960 --> 06:42.120 And we need to make this brackets and this instantiate function as a first argument. 06:42.120 --> 06:45.000 It's going to take the game object that we want to spawn. 06:45.000 --> 06:46.960 So in our case arrow prefab. 06:47.160 --> 06:51.160 And the second thing it's going to take the position from where we want to shoot out. 06:51.160 --> 06:57.160 So we also need to create our shoot point or fire point where from we want to fire. 06:57.280 --> 06:58.540 And the third Another argument. 06:58.540 --> 07:00.260 It's gonna take the rotation. 07:00.580 --> 07:03.060 Uh, so we need to assign those variable. 07:03.060 --> 07:07.380 So let's make this one comment for now by double forward slash. 07:07.380 --> 07:09.380 And let's go to top of our class. 07:09.380 --> 07:11.540 And let's grab those reference first. 07:11.540 --> 07:15.300 So the first thing we need we have the arrow prefab. 07:15.460 --> 07:17.940 So the second thing we need our position. 07:17.940 --> 07:22.740 So let's make a serialized pill private a private. 07:22.740 --> 07:28.420 And for position we're going to type this transform which is responsible responsible for position. 07:28.420 --> 07:31.060 And we can call this one fire point. 07:31.060 --> 07:32.860 So let's call it fire point. 07:32.860 --> 07:34.980 And let's close that up with semicolon. 07:34.980 --> 07:40.300 And let's create another variable for our arrow speed with how much speed. 07:40.340 --> 07:42.300 We just want to shoot out the arrow. 07:42.300 --> 07:48.100 So let's create another serialized field private and we can call this will be float. 07:48.100 --> 07:54.500 And we can call this one arrow arrow speed something like that or arrow fire speed. 07:54.740 --> 07:58.720 And by default I'm going to set equal to ten unit Ten F. 07:58.880 --> 08:03.280 And let's press down control S on our keyboard in order to save our skate. 08:03.320 --> 08:05.320 And now let's move over to unity. 08:05.600 --> 08:08.400 So we will see underneath our enemy one. 08:08.400 --> 08:09.280 Skip those fields. 08:09.280 --> 08:10.240 Just gonna pop up. 08:10.360 --> 08:14.000 So first thing we need to assign our, uh, fire point. 08:14.000 --> 08:20.160 So we basically have to create our fire point from where we want to shoot out the, uh, shoot out, 08:20.160 --> 08:22.440 or want to fire our arrow. 08:22.520 --> 08:24.320 So we need to assign that. 08:24.320 --> 08:30.440 As you can see, as soon as our skip compiles, we can see fire point and it says none transform. 08:30.560 --> 08:32.520 So let's create our fire point. 08:32.680 --> 08:35.720 So let's select our enemy one GameObject in the hierarchy. 08:35.720 --> 08:37.480 Let's create a right click on it. 08:37.480 --> 08:39.960 And let's create an empty game object. 08:39.960 --> 08:46.960 And we can call this GameObject to something like fire uh fire point, uh fire point. 08:47.240 --> 08:49.560 And let's choose an gizmos for it. 08:49.560 --> 08:53.320 So let's go over to Inspector, click here and I'm gonna choose this one. 08:53.520 --> 08:56.360 And let's move it somewhere around here. 08:56.800 --> 09:00.540 And you can check that by selecting your anime one. 09:00.580 --> 09:05.020 Then moving over to animation tab, then choose the Arrow Animation clip. 09:05.180 --> 09:09.140 So I guess Arrow Fire should be right over here. 09:09.260 --> 09:11.220 So this is gonna be perfect point. 09:11.340 --> 09:13.540 So make sure you just adjust that. 09:13.540 --> 09:15.740 And now this seems pretty much fine. 09:15.980 --> 09:22.340 And once you are satisfied, make sure if you turn it your anime one into prefab, then go over to Inspector 09:22.340 --> 09:24.380 Overrides and then apply all. 09:24.540 --> 09:29.340 And we're going to take our fire point and let's drag it over to this fire point slot. 09:29.380 --> 09:34.660 Now we can see we have the fire point as well as the arrow, and we are ready to spawn it. 09:34.660 --> 09:39.300 So let's open up our anime one strip and let's move over to that function. 09:39.300 --> 09:42.180 And let's remove this two forward slashes. 09:42.180 --> 09:45.180 So this instantiate function as a first argument. 09:45.180 --> 09:48.060 It's going to take the GameObject that we want to spawn. 09:48.060 --> 09:51.700 So we will pass our arrow prefab and arrow prefab. 09:51.740 --> 09:56.260 We do know that we just pass our arrow as you seen earlier. 09:56.260 --> 09:58.520 And the second thing it's going to take the point. 09:58.520 --> 10:02.040 So we will pass our fire point dot position. 10:02.040 --> 10:07.600 And we do know that as a fire point we just drag it that fire point as you seen. 10:07.880 --> 10:10.440 And the third argument it's going to take the rotation. 10:10.440 --> 10:13.360 So we're going to put two quaternion dot identity. 10:13.400 --> 10:15.400 It basically means no rotation. 10:15.400 --> 10:17.680 And let's close that up with semicolon. 10:17.680 --> 10:20.520 And we're going to press down Ctrl s to save our script. 10:20.520 --> 10:22.320 And now let's move over to unity. 10:22.640 --> 10:25.400 So we just created that spawn arrow function. 10:25.400 --> 10:29.320 So we also need to call in order to spawn our arrow. 10:29.320 --> 10:37.760 So when we need to call it once our enemy this enemy one basically playing that arrow fire animation 10:37.760 --> 10:38.240 clip. 10:38.240 --> 10:41.040 So we will select our enemy one in the hierarchy. 10:41.080 --> 10:42.880 Then move over to animation tab. 10:42.880 --> 10:46.920 Let's click here and we're going to choose our Arrow Fire animation. 10:46.920 --> 10:49.600 Let's move it over to something over here. 10:49.600 --> 10:51.400 So this is going to be perfect time. 10:51.400 --> 10:55.800 So from here we want to call this function which is our spawn arrow. 10:56.080 --> 11:02.100 And in order to call that in this animation tab in the left side we can see Add event basically right 11:02.100 --> 11:02.580 over here. 11:02.580 --> 11:05.260 So just click that and then select that event. 11:05.300 --> 11:06.700 Then go over to Inspector. 11:06.740 --> 11:08.140 As you can see function. 11:08.140 --> 11:09.900 And it says no function. 11:09.900 --> 11:14.540 So we will click there and we will go to anime script or anime class. 11:14.580 --> 11:16.420 Then methods basically function. 11:16.420 --> 11:19.780 And there as you can see we created spawn arrow function. 11:19.780 --> 11:21.140 So we're going to choose that. 11:21.140 --> 11:28.780 Now uh, whenever this anime is just going to play this animation clip right over here, that uh, spawn 11:28.820 --> 11:31.060 arrow function, just going to call out. 11:31.060 --> 11:36.220 And we do know that what that function is really doing, it just spawning our arrow. 11:36.220 --> 11:37.180 So let's have a look. 11:37.220 --> 11:41.420 As you can notice right over here I'm going to clear my console tab. 11:41.860 --> 11:46.780 And let's click on this play button in the top in order to play our game. 11:46.780 --> 11:48.900 And let's get in attack range. 11:48.900 --> 11:54.460 So when we whenever we're gonna move over to our attack range you will see that. 11:56.100 --> 11:57.200 So just wait. 11:58.760 --> 12:05.920 So if we get in attack range, as you can see, as soon as we get we can see arrow prefab just spawning 12:05.920 --> 12:06.720 from that. 12:07.040 --> 12:10.000 Uh, and you can notice right over here. 12:10.000 --> 12:14.160 But the problem is that it's staying at one position. 12:14.160 --> 12:17.960 Also it's pushing our player to the right direction. 12:18.040 --> 12:21.760 So what we need to do, we basically have to tweak some values. 12:21.960 --> 12:24.080 So firstly it's not moving. 12:24.080 --> 12:25.640 So let's get out of play mode. 12:25.880 --> 12:33.280 Uh before we do it let's add let's deal with uh, that uh, our arrow just pushing our player to the 12:33.280 --> 12:34.120 right direction. 12:34.160 --> 12:39.800 So basically what we have to do, we need to move over to our project tab, then assets and then prefabs 12:39.800 --> 12:40.360 folder. 12:40.360 --> 12:42.440 And we will select our arrow prefab. 12:42.440 --> 12:45.320 Then go over to Inspector, then Box Collider 2D. 12:45.320 --> 12:47.840 And make sure you just check this trigger. 12:47.840 --> 12:50.840 So it's just gonna, uh check for trigger. 12:50.840 --> 12:58.740 So uh, trigger and it's not gonna push, uh, our player, uh, player basically for trigger and now 12:58.780 --> 12:59.980 and that's fine. 13:00.180 --> 13:02.740 And now it's not gonna push our player. 13:02.740 --> 13:05.340 So let's click on this play button in the top. 13:05.540 --> 13:08.020 Basically we just checking for trigger. 13:08.020 --> 13:12.420 And, uh, when we gonna trigger, uh, with anything. 13:12.420 --> 13:14.140 Not, uh, for collision. 13:14.140 --> 13:17.540 So when we're gonna trigger, that just gonna happen. 13:17.940 --> 13:20.620 It's not gonna push our player, as you can see. 13:20.660 --> 13:22.620 And this seems pretty much fine. 13:22.940 --> 13:28.380 When we get outside of this attack range, we can see enemy stops shooting out. 13:28.580 --> 13:29.900 Uh, arrow, arrow. 13:29.900 --> 13:37.780 Once we are out of, uh, once we are out of from our attack range of this enemy one game object. 13:37.780 --> 13:41.660 So these arrows are just staying at one position. 13:41.660 --> 13:45.660 So we need to just we need to move this arrow. 13:45.660 --> 13:47.380 So let's get out of play mode. 13:47.380 --> 13:52.900 And in order to move that arrow, we basically have to grab the reference of this rigid body. 13:52.900 --> 13:58.770 So if we if I select my arrow prefab from that prefab folder and go over to Inspector. 13:58.810 --> 14:02.130 As you can see, we added a rigid body to the component. 14:02.130 --> 14:08.930 And this component is responsible for velocity, adding force and all of kind of things. 14:09.010 --> 14:15.730 So what we need we need a reference of this component which is rigid body 2D of this arrow prefab GameObject. 14:15.770 --> 14:18.810 Then we can just add a add up the velocity. 14:18.930 --> 14:22.170 So let's go over to Inspector Sorry script. 14:22.610 --> 14:26.810 So we spawning this arrow prefab at this position with no rotation. 14:26.810 --> 14:31.650 So after spawning that arrow we're going to put that arrow into another game object. 14:31.650 --> 14:36.490 Or you can simply say into another container and that will be GameObject. 14:36.530 --> 14:36.890 Why? 14:36.930 --> 14:41.010 Because this arrow prefab itself a game object and we have to name it. 14:41.010 --> 14:44.810 So we can call this one arrow prefab. 14:44.810 --> 14:47.290 So let's call it arrow prefab. 14:47.530 --> 14:50.010 And let's set equal to this. 14:50.010 --> 14:51.130 Basically what we're doing. 14:51.130 --> 14:58.230 We just are taking this arrow prefab where wherever we spawning and we just storing that arrow that 14:58.230 --> 15:01.430 we spawn it into this arrow prefab. 15:01.590 --> 15:05.230 And now what we're going to do, we're going to access the rigid body. 15:05.350 --> 15:12.070 So we will use this stem arrow prefab dot game object dot get component. 15:12.070 --> 15:15.150 And the component we're looking for is a rigid body 2D. 15:15.150 --> 15:18.750 So we're going to type rigid body 2D and then make this brackets. 15:19.030 --> 15:22.630 And we can set equal to uh sorry. 15:22.670 --> 15:24.350 We can set the velocity. 15:24.350 --> 15:28.830 So we will type this linear velocity equal to that we want. 15:28.870 --> 15:30.950 So let me explain one more time. 15:30.990 --> 15:37.710 Firstly we spawning this arrow prefab in from this spawn position which is fire point or position with 15:37.710 --> 15:38.510 no rotation. 15:38.710 --> 15:44.750 And after spawning we just taking that arrow prefab and we storing that arrow prefab into this stem 15:44.790 --> 15:45.750 arrow prefab. 15:45.870 --> 15:51.790 And after that what we're doing we're just going over to temp arrow prefab and accessing the whole game 15:51.830 --> 15:52.190 object. 15:52.190 --> 15:56.610 So in our case basically we're just going over to this arrow game object. 15:56.610 --> 16:00.890 And then we're using this dot get component in order to get the component. 16:00.890 --> 16:05.890 And the component we're looking for is a rigid body 2D as you can see right over here. 16:05.930 --> 16:12.290 Basically we're just going over to this arrow prefab and then accessing this rigid body 2D and then 16:12.330 --> 16:14.570 accessing the velocity of it. 16:14.570 --> 16:17.770 Linear velocity as you can see right over here. 16:17.930 --> 16:18.450 Sorry. 16:20.490 --> 16:21.450 Just a little bit. 16:21.490 --> 16:22.810 I really apologize. 16:23.410 --> 16:24.290 Let's go back. 16:24.690 --> 16:29.450 So we just accessing the velocity linear velocity of that arrow. 16:29.650 --> 16:32.650 And now what we have to do we need to set the velocity. 16:32.810 --> 16:40.730 So firstly what we will do we will set the velocity with our uh basically uh we created arrow Spirit 16:40.730 --> 16:41.770 right over here. 16:41.770 --> 16:43.970 So we're going to pass our arrow speed. 16:44.010 --> 16:45.930 So let's pass arrow speed. 16:46.250 --> 16:46.970 Arrow speed. 16:46.970 --> 16:49.130 And let's close that off with semicolon. 16:49.450 --> 16:52.450 Uh so as you can see we're getting an error. 16:52.450 --> 16:55.110 Basically we need to convert this into a factor two. 16:55.310 --> 16:59.510 Basically what we will do right over here we're going to put transform. 16:59.830 --> 17:00.310 Sorry. 17:01.550 --> 17:04.710 Uh transform transform dot. 17:05.030 --> 17:06.430 Sorry not transform dot. 17:06.470 --> 17:07.030 Right. 17:07.070 --> 17:10.950 Basically we're going to use fire point dot right. 17:11.110 --> 17:12.550 Fire point dot right. 17:12.550 --> 17:18.710 So what basically this mean fire point dot right means that which direction our fire point is facing. 17:18.710 --> 17:24.510 So if I choose my fire point underneath my enemy point game object in the hierarchy, as you can see, 17:24.710 --> 17:27.550 our fire point is facing right direction. 17:27.550 --> 17:32.790 So fire point dot right basically means which direction our fire point is facing. 17:32.790 --> 17:36.750 So we want to move our arrow prefab to the left direction. 17:36.750 --> 17:41.830 So that's why right in front of this fire point dot right we're going to put minus. 17:41.830 --> 17:43.950 Now it's going to be left direction. 17:43.950 --> 17:48.950 And we we're just going to multiply that direction with our arrow speed. 17:48.950 --> 17:52.030 So as so our arrow is just going to move. 17:52.030 --> 17:53.030 So what we will do. 17:53.070 --> 17:57.850 We just going to want to multiply this 5.0 right, with our arrow speed. 17:57.970 --> 17:58.690 Arrow speed. 17:58.730 --> 18:00.170 Let's multiply that. 18:00.170 --> 18:04.850 And now that arrow is just gonna move with this arrow speed. 18:04.850 --> 18:11.090 So firstly what we're doing we just accessing the rigid body 2D component of that arrow prefab and then 18:11.090 --> 18:12.570 accessing the velocity. 18:12.570 --> 18:17.570 And we setting the velocity equal to which direction our fire point is facing. 18:17.570 --> 18:22.650 And we just put minus basically now it's gonna be a left direction. 18:22.650 --> 18:25.770 And we just multiply that direction with our arrow. 18:25.770 --> 18:32.490 Speed basically means that that arrow just gonna move with uh, with this much of arrow speed, as we 18:33.250 --> 18:35.170 specified right over here. 18:35.170 --> 18:41.650 So since we just made it serialized field so we can access this parameter underneath our enemy one script. 18:41.650 --> 18:44.810 So there we can just adjust if we want. 18:45.050 --> 18:49.290 So now what we're gonna do, we're gonna press control S to save our script. 18:49.290 --> 18:52.250 And now let's move over to unity and you will see. 18:55.830 --> 18:59.630 So just wait a little moment and you will see that. 19:04.030 --> 19:05.950 So let's have a look. 19:06.630 --> 19:09.230 So I'm going to click on this play button in the top. 19:09.230 --> 19:16.510 So as soon as this anime one game object just going to play arrow fire animation clip then arrow just 19:16.510 --> 19:17.230 going to spawn. 19:17.230 --> 19:19.950 And that arrow just going to move in the direction. 19:20.110 --> 19:22.830 Uh, in the direction uh, fire point is facing. 19:22.830 --> 19:28.110 Basically negative direction in the fire point is facing means to the left direction. 19:28.110 --> 19:29.870 So let's get in attack range. 19:29.870 --> 19:34.030 And we can see by now arrow is just going to the left direction. 19:34.030 --> 19:40.350 As you can see fire point dot right basically means right direction, the direction our fire point is 19:40.350 --> 19:40.950 facing. 19:40.950 --> 19:47.470 And we just put minus uh, to uh, to basically move uh, over to negative direction. 19:47.470 --> 19:50.070 And we can see indeed it's working fine. 19:50.230 --> 19:55.010 But the problem is that as you can see, uh, our, uh, arrow. 19:55.210 --> 20:00.850 Once we are to the right direction, we can see that our arrow is, uh. 20:01.610 --> 20:02.530 You can simply. 20:02.570 --> 20:03.770 I'm going to pause my game. 20:04.010 --> 20:08.050 Arrow is not facing to the, uh, to the right direction. 20:08.090 --> 20:12.330 Once we shooting out the shooting out this way, to the right direction. 20:12.330 --> 20:13.930 So we need to flip this. 20:14.010 --> 20:17.970 Uh, basically, we need to work with rotation of this arrow prefab. 20:17.970 --> 20:24.410 So let's get out of play mode and what we have to basically do their, uh, so instead of typing quaternion 20:24.410 --> 20:27.130 dot identity basically means no rotation. 20:27.170 --> 20:34.210 We're going to pass this fire point dot rotation and fire point dot rotation basically means the rotation 20:34.210 --> 20:36.050 fire point is facing. 20:36.050 --> 20:38.010 Now it should be work fine. 20:38.010 --> 20:40.890 So we're going to press down Ctrl S to save our script. 20:40.930 --> 20:42.770 And let's move over to unity. 20:42.770 --> 20:50.210 So now by by now that arrow just gonna rotate in the direction fire point is rotating. 20:50.490 --> 20:52.490 So it will be okay by now. 20:52.490 --> 20:56.270 But, before we have it, let's take a look on it. 20:57.590 --> 21:00.990 So what we will do, we're going to play our game. 21:01.270 --> 21:04.590 Firstly I'm going to select my enemy one game object in the hierarchy. 21:04.590 --> 21:07.830 And let's press down F in order to focus on it. 21:08.190 --> 21:12.190 So let's click on this play button in the top in order to play our game. 21:12.190 --> 21:14.030 And let's test that out. 21:15.550 --> 21:22.230 So now the rotation just gonna just gonna be find of that arrow because we just type fire point dot 21:22.270 --> 21:29.630 rotation basically means that arrow just gonna rotate rotate with our fire point dot rotation. 21:29.630 --> 21:30.670 So let's get in. 21:30.910 --> 21:32.350 And if we just move. 21:32.350 --> 21:38.310 And now as you can notice, if I pause my game, we can see the rotation of this arrow. 21:38.350 --> 21:40.150 It's now to the right direction. 21:40.150 --> 21:47.310 Once our player once our enemy one shooting out the arrow to the right direction. 21:47.350 --> 21:51.350 Now our arrow just facing to the right direction. 21:51.350 --> 21:52.810 So Direction. 21:52.810 --> 21:54.690 We just work with rotation. 21:54.690 --> 22:00.130 So instead of passing right over here, quaternion dot identity basically means no rotation. 22:00.130 --> 22:06.730 Pass fire point dot rotation means the rotation will be with our fire point dot rotation. 22:06.730 --> 22:11.530 So I hope you get the idea and what we need to do after some period of time. 22:11.530 --> 22:13.450 We need to destroy these arrows. 22:13.730 --> 22:15.930 We need to destroy these arrows. 22:15.930 --> 22:18.090 So let's get out of play mode for it. 22:18.090 --> 22:19.770 We're gonna create a script. 22:19.770 --> 22:24.330 So what we're gonna do and we're gonna attach that script to this, our arrow. 22:24.530 --> 22:26.410 So let's create a script for it. 22:26.410 --> 22:30.770 So we will head over to our project tab assets and then script folder. 22:30.810 --> 22:34.530 Let's right click there then create Monobehaviour script. 22:34.530 --> 22:38.770 Or you can move over to scripting and then click on this Monobehaviour script. 22:38.770 --> 22:41.250 And you can name that script whatever you like. 22:41.250 --> 22:42.970 Just name it something like arrow. 22:43.210 --> 22:46.970 As you can see, I already created a arrow script. 22:46.970 --> 22:49.770 So what I'm going to do, I'm going to select my arrow prefab. 22:49.810 --> 22:51.410 Let's double click on it. 22:51.450 --> 22:56.910 And in order to open that up in prefab mode, and we're gonna attach our arrow script. 22:56.910 --> 23:02.190 So I will head over to my script folder and let's select this arrow script and drag it over to this 23:02.230 --> 23:04.550 add Component section and Inspector. 23:04.550 --> 23:07.110 Or we can simply click on this add component. 23:07.110 --> 23:12.430 And we can find the script by typing the name of the script which is arrow, and we can hit enter in 23:12.430 --> 23:13.870 order to attach that. 23:13.910 --> 23:17.790 I'm not gonna do it twice since I already attached my arrow script. 23:17.790 --> 23:22.670 So I'm gonna go back and let's open up the arrow script by double clicking on it. 23:22.670 --> 23:27.830 Make sure you attach this as arrow script, uh, to that arrow game object. 23:27.830 --> 23:30.430 So we will move over to this start function. 23:30.430 --> 23:34.430 So we do know that start function get call in the start of the game. 23:34.430 --> 23:36.990 So in the start of the game we will destroy. 23:36.990 --> 23:39.430 But we don't want to destroy immediately. 23:39.470 --> 23:42.230 We want to destroy after some period of time. 23:42.230 --> 23:46.230 So as a second argument we can just specify the time. 23:46.470 --> 23:50.350 So to destroy we're gonna use destroy this destroy function. 23:50.350 --> 23:55.690 And this destroy function as a first argument, it's going to take the game object we want to destroy. 23:55.810 --> 23:58.650 So we want to destroy game object itself. 23:58.650 --> 24:01.210 So we will pass this dot game object. 24:01.210 --> 24:06.450 And this dot game object basically means it's referencing our game object itself comma. 24:06.490 --> 24:08.690 Second thing it's going to take the time. 24:08.690 --> 24:11.810 So after five seconds I want to destroy or seven. 24:11.810 --> 24:15.810 So I'm gonna put seven and then close that up with semicolon. 24:15.970 --> 24:21.850 And if you want to adjust then you can just go over to top of your class and you can make a variable 24:21.850 --> 24:22.450 for it. 24:22.450 --> 24:24.370 So let's make a serialize field. 24:24.730 --> 24:29.290 So alias field private and private this will be float. 24:29.290 --> 24:32.890 And we can call this something like destroy time. 24:32.890 --> 24:37.490 So let's call it Destroy and destroy time. 24:37.490 --> 24:40.090 And by default I'm going to set it to something like five. 24:40.530 --> 24:44.050 And let's replace this seven F with our destroy time. 24:44.370 --> 24:47.250 So let's replace this with our destroy time. 24:47.450 --> 24:53.230 And we do know that we just marked as serialized field so we can adjust the time in Inspector and we 24:53.230 --> 24:54.870 will remove this update function. 24:54.870 --> 24:58.750 We don't need it and we're going to use some certain function later. 24:58.990 --> 25:02.470 So let's press down Ctrl S in order to save our script. 25:02.470 --> 25:07.630 And let's have a look and make sure you attach that script to your arrow game object. 25:07.950 --> 25:15.910 Uh, so, uh, so our arrow is just gonna destroy itself after with our, uh, after, uh, after, 25:15.910 --> 25:18.950 you can say with destroy time. 25:19.510 --> 25:23.110 Destroy time, as we specified in our script. 25:23.110 --> 25:25.790 So now let's have a look. 25:25.790 --> 25:27.670 So I'm going to click on this play button. 25:27.670 --> 25:35.270 So you will see as soon as our uh, as soon as, uh, our destroy time just going to be over basically 25:35.470 --> 25:39.070 arrow just going to destroy itself after that amount. 25:39.110 --> 25:40.150 Destroy time. 25:40.630 --> 25:41.670 So let's have a look. 25:41.670 --> 25:45.950 So if I if we get in attack range, we can see it's shooting out the ray. 25:45.950 --> 25:52.930 And you will see this arrow just going to destroy itself after after that destroy time amount. 25:52.970 --> 25:56.450 As you can see, indeed it destroying right over here. 25:56.450 --> 25:59.850 So after something like five seconds it just destroying itself. 25:59.930 --> 26:05.690 So if I get out of play mode and then move over to my prefabs folder and then select this arrow, we 26:05.690 --> 26:08.410 can see our in our arrow script. 26:08.410 --> 26:11.570 In Inspector Destroy Time, we have chosen five. 26:11.610 --> 26:12.770 You can make it less. 26:12.770 --> 26:13.930 You can make it bigger. 26:13.930 --> 26:15.570 It's basically up to you. 26:15.570 --> 26:21.890 So I hope you get the idea that how you can just do it and make sure you attach your arrow script to 26:21.930 --> 26:23.970 your arrow prefab game object. 26:23.970 --> 26:27.530 So it's gonna do that thing, or else you're gonna get some error. 26:27.530 --> 26:35.850 So you need to make sure that and whatever changes we have done now in in this anime one game object. 26:35.850 --> 26:39.810 So let's move over to Inspector Overrides and then apply all. 26:39.810 --> 26:46.490 So the changes we made over here, it's going to be saved into this enemy one GameObject prefab as well. 26:46.690 --> 26:51.650 And I'm gonna press Ctrl S on my keyboard in order to save my project.
