WEBVTT 00:00.040 --> 00:04.640 We will create a anime script in order to attack on this player game object. 00:04.640 --> 00:05.680 So let's do that. 00:05.680 --> 00:09.200 So we're gonna move over to project tab assets and then script folder. 00:09.200 --> 00:14.800 Let's right click there create and then Monobehaviour script and name it to something like anime. 00:14.840 --> 00:18.160 I already created this anime script as you can see. 00:18.160 --> 00:19.360 So now we need to attach. 00:19.360 --> 00:22.680 So let's select our anime one game object in the hierarchy. 00:22.680 --> 00:27.600 And we're going to drag this anime anime script in this add component section. 00:27.600 --> 00:29.280 And now we can see we attach. 00:29.320 --> 00:32.200 And let's open up this script by double clicking on it. 00:32.520 --> 00:35.720 So what we need we need our player transform. 00:35.760 --> 00:39.120 So basically you can simply call player position. 00:39.120 --> 00:41.680 So we can just keep track of where player is. 00:41.720 --> 00:47.680 And if the player gets an attack range of this enemy game object, then this enemy need to play the 00:47.680 --> 00:55.280 attack animation as well as it need to fire on this anime game object, or it's just need to shoot on 00:55.280 --> 00:57.000 this enemy game object. 00:57.000 --> 00:58.120 So we're going to do that thing. 00:58.120 --> 01:03.560 So let's open up our anime script and we what we need our player transform. 01:03.600 --> 01:09.840 So let's go to the top of our class and we're going to declare, or we're gonna grab the reference of 01:09.840 --> 01:11.320 our player position. 01:11.320 --> 01:16.480 So let's create a public that will be transform, which is responsible for position. 01:16.480 --> 01:20.400 And we can simply call it something like player or player position. 01:20.600 --> 01:26.000 And also we're going to create a second parameter or we're going to call it something like attack range. 01:26.160 --> 01:33.840 And it's just going to keep track of the basically we can define an range and you can simply call a 01:33.840 --> 01:34.480 attack range. 01:34.480 --> 01:40.680 And if this player game object gets inside of that attack range, then this enemy game object need to 01:40.720 --> 01:43.000 fire on this player game object. 01:43.000 --> 01:44.440 So let's go to script. 01:44.440 --> 01:48.600 So we're going to define or declare another variable which will be float. 01:48.600 --> 01:52.000 And we can call this one to something like attack range. 01:52.240 --> 01:54.160 So we're going to call it attack range. 01:54.160 --> 01:59.040 And by default I'm going to give a default value something like five f or five unit. 01:59.040 --> 02:01.520 And let's close that up with some my colon. 02:01.800 --> 02:05.000 And let's press control S in order to save our skin. 02:05.080 --> 02:07.080 And now let's move over to unity. 02:07.560 --> 02:11.200 So we're going to able to see that underneath our anime script. 02:11.200 --> 02:12.840 We need to drag our player. 02:12.880 --> 02:16.120 Transform means player position into that slot. 02:16.600 --> 02:20.280 And we're also going to able to see the attack range. 02:20.480 --> 02:26.320 So as soon as the anime script gets compiled, we can see underneath our anime script and it says Player 02:26.960 --> 02:27.440 Transform. 02:27.440 --> 02:31.600 So we need to select our player game object in the hierarchy and drag it right there. 02:31.640 --> 02:36.080 Now we can see we have player transform means position and attack range. 02:36.080 --> 02:40.600 I'm going to set in Inspector something like let's set it to seven unit. 02:40.600 --> 02:44.000 But you can increase the increase this value as well. 02:44.000 --> 02:46.400 It's basically totally up to you. 02:46.400 --> 02:52.560 So now let's open up our anime script and let's move over to this update function and what we want to 02:52.560 --> 02:53.040 do. 02:53.080 --> 02:54.960 We're going to use this physics 2D. 02:55.240 --> 03:04.440 So physics 2D dot overlap circle overlap circle overlap circle and make first bracket and then close 03:04.440 --> 03:05.800 that output semicolon. 03:05.800 --> 03:07.440 Basically what we want to do. 03:07.440 --> 03:13.360 We're going to create a circle around this anime game object with this much of attack range radius. 03:13.360 --> 03:15.360 As you can see, we set it seven. 03:15.360 --> 03:20.400 So with seven unit we're going to create a circle around this anime game object. 03:20.400 --> 03:26.560 And if this player game object collides with that circle or just gets in attack range of that radius 03:27.280 --> 03:33.000 than this anime game object need to attack, or it just should play the attack animation or the fire 03:33.040 --> 03:35.880 animation of this anime game object. 03:35.880 --> 03:37.480 So let's go to script. 03:37.480 --> 03:40.320 So this physics studio overlap circle. 03:40.520 --> 03:43.720 We're going to use this function in order to create the circle. 03:43.720 --> 03:49.960 So we need to use this physics overlap circle function in order to create the circle from this anime 03:49.960 --> 03:52.000 game object center position. 03:52.000 --> 03:57.440 So as a first argument it's going to take the position from where we want, where you just want to create 03:57.440 --> 03:58.160 the circle. 03:58.160 --> 04:01.000 So we're going to create our transform dot position. 04:01.000 --> 04:06.920 And transform dot position basically means the current position of the center position of our enemy 04:06.960 --> 04:07.760 game object. 04:07.800 --> 04:13.320 Comma as a second argument, it's going to take the radius with how much radius you just want to create 04:13.320 --> 04:14.000 the circle. 04:14.000 --> 04:17.440 So we're going to create the circle around this attack range radius. 04:17.440 --> 04:21.600 So we can simply call this one as well attack radius something like that. 04:21.600 --> 04:23.600 But I'm going to leave it to attack range. 04:23.600 --> 04:26.480 So I'm going to pass as a second argument attack range. 04:26.480 --> 04:31.400 And the third argument it's going to take the layer mask or basically which game object you want to 04:31.400 --> 04:31.840 target. 04:31.840 --> 04:33.840 So we're going to target this player game object. 04:33.840 --> 04:37.560 So we need to assign this player game object as a player layer. 04:37.800 --> 04:39.680 So how you can just do that. 04:39.680 --> 04:41.880 But before we do let's go to script. 04:41.880 --> 04:43.880 And we need to go to top of our class. 04:43.880 --> 04:47.600 And we need to assign or declare that variable as well. 04:47.600 --> 04:51.240 So I'm going to make this one public and that will be layer mask. 04:51.400 --> 04:55.000 And we can call this one to something like target layer or attack layer. 04:55.000 --> 04:57.640 So I'm going to call it instead target layer. 04:57.880 --> 05:04.120 And let's close that up with semicolon as a third parameter I'm going to pass the target layer and let's 05:04.400 --> 05:07.400 press down Ctrl S in order to save our script. 05:07.400 --> 05:13.320 And let's move to unity because we need to assign Assign those variable first one by one, and then 05:13.320 --> 05:15.680 we can just create the circle right away. 05:15.680 --> 05:20.120 But before we do we're going to assign this player game object as a player layer. 05:20.120 --> 05:21.440 So how you can do that. 05:21.440 --> 05:24.200 You need to select the game object first in the hierarchy. 05:24.200 --> 05:25.640 And then you have to do it. 05:25.640 --> 05:27.800 So we're going to select our player game object. 05:27.800 --> 05:30.880 And if we go to Inspector top right we can see layer. 05:30.880 --> 05:32.200 And it says default. 05:32.200 --> 05:37.880 So we need to assign this player as a player layer in order to attack this player game object. 05:37.880 --> 05:38.680 So that's why. 05:38.720 --> 05:42.720 So let's go to click on this layer and then click on this add layer. 05:43.040 --> 05:47.320 And we're going to create a another layer for this player game object. 05:47.320 --> 05:50.000 So I'm going to call this one something like player. 05:50.320 --> 05:51.280 And hit enter. 05:51.280 --> 05:56.440 And make sure you select the game object one more time the player and then go to Inspector and Layer. 05:56.440 --> 05:58.280 As you can see it says default. 05:58.280 --> 05:59.800 So we're going to assign with player. 05:59.920 --> 06:02.240 And we're going to do with this game object only. 06:02.240 --> 06:03.920 So that's why we're going to click on this. 06:03.960 --> 06:05.480 Yes or no. 06:05.520 --> 06:05.960 Sorry. 06:06.000 --> 06:07.920 We're not going to change the children. 06:08.040 --> 06:13.710 Instead we're going to do no this game object only or we basically just doing with this player game 06:13.750 --> 06:14.590 object only. 06:14.590 --> 06:18.870 And if I select the child game object and then move to Inspector, we can see this. 06:18.870 --> 06:23.670 It says Layer player, but I'm going to remove that instead I'm going to set it to default. 06:23.670 --> 06:27.070 And now what we will do, we will select our enemy game object. 06:27.070 --> 06:32.590 And we can see underneath our enemy script a target layer pops up and it says nothing. 06:32.590 --> 06:35.630 And we do know we assign it this player as a player layer. 06:35.630 --> 06:37.270 So I'm going to choose that player. 06:37.270 --> 06:38.230 So let's click there. 06:38.230 --> 06:43.470 And I'm going to choose this player so that the circle only going to check for this player game object. 06:43.510 --> 06:45.630 Basically we want to damage our player. 06:45.630 --> 06:51.710 So that's why we just only have chosen that player layer as you can see as a target layer. 06:51.710 --> 06:58.430 So now let's move to a script and we can see we use this function physics 2D dot overlap circle. 06:58.430 --> 07:01.390 In order to create the circle around center position. 07:01.390 --> 07:05.350 With this much of radius and we have only chosen target layer. 07:05.350 --> 07:08.310 And we do know as a target layer we have chosen player. 07:08.310 --> 07:11.670 So the circle only going to check for that player game object. 07:11.670 --> 07:17.110 So this can be true or false depending upon if the circle is really colliding with this player game 07:17.150 --> 07:17.990 object or not. 07:18.030 --> 07:21.070 If it's a, then this is gonna give us a true value. 07:21.110 --> 07:23.550 Else it's gonna give us a false value. 07:23.550 --> 07:27.310 So what we will do, we will store the result into a collider 2D. 07:27.350 --> 07:27.790 Why? 07:27.830 --> 07:29.950 Because this is work like as a collision. 07:29.950 --> 07:33.990 So that's why we're gonna store the result into a collider 2D variable. 07:33.990 --> 07:34.990 So let's store that. 07:34.990 --> 07:39.950 So we're going to say we're going to set Collider 2D equal to call info. 07:39.950 --> 07:44.390 Or you can simply say call information or collision information. 07:44.390 --> 07:46.590 And we're gonna set equal to this. 07:46.910 --> 07:53.510 So this call info can be true or false depending upon what this function gives us or return us. 07:53.550 --> 07:57.470 If the circle is really colliding, then it's going to give us a true value. 07:57.470 --> 08:02.710 So that's why this call info is just gonna be true right away, because we directly setting it, as 08:02.710 --> 08:03.390 you can see. 08:04.150 --> 08:07.190 And now what we're going to do, we're going to check in the next line. 08:07.190 --> 08:14.350 We will check if so make first bracket and some curly brackets and what we want to check over here. 08:14.350 --> 08:17.030 We want to check if call info is true. 08:17.030 --> 08:22.990 So we're going to say if call info is equals, equals to true basically means the circle is really collided 08:22.990 --> 08:24.550 with this player game object. 08:24.950 --> 08:31.070 Uh so call info is going to be true means the circle is really colliding with this player game object. 08:31.110 --> 08:35.190 Then what we need to do this player game object need to attack on this. 08:35.230 --> 08:38.270 Or it should fire on this player game object. 08:38.470 --> 08:42.750 So for now we're going to print out a message if it's perfectly working or not. 08:42.750 --> 08:43.550 So we're going to check. 08:43.550 --> 08:47.750 So we're going to type debug dot log in order to print out a message. 08:47.750 --> 08:50.670 Then make first bracket and close that up with semicolon. 08:50.670 --> 08:53.150 And we're going to print out a message something like. 08:53.150 --> 09:01.110 So I'm going to print out attack attack on player and make sure you just close that off with semicolon. 09:01.110 --> 09:03.910 And we're going to press down Ctrl S to save our script. 09:04.030 --> 09:05.910 And let's move over to unity. 09:06.430 --> 09:11.670 But we're not going to able to see the circle that we created around this enemy game object. 09:11.670 --> 09:18.390 So what we need to do, we need to use another function in order to draw the circle around this A game 09:18.430 --> 09:18.950 object. 09:19.190 --> 09:24.990 So as soon as the anime script gets compiled, we're not able to see our circle. 09:24.990 --> 09:29.870 So it would be nice if we able to see our circle with this much of radiance. 09:29.870 --> 09:30.990 So let's go to script. 09:30.990 --> 09:36.190 And for that we're going to use another function and it's called on draw gizmo selected function. 09:36.190 --> 09:36.910 We don't know. 09:37.070 --> 09:40.310 So first thing we uh, we want to draw. 09:40.430 --> 09:46.110 And in order to draw we need to use this gizmos dot draw function draw wire sphere function. 09:46.110 --> 09:49.310 So make sure you are doing as I did over here. 09:49.350 --> 09:50.910 Else it's not going to work. 09:50.910 --> 09:55.510 So make sure you just use this function on draw gizmo selected. 09:55.510 --> 09:58.630 Uh and this function is unity callback function. 09:58.630 --> 10:01.230 So you need to make as I did over here. 10:01.270 --> 10:05.110 Else you're not going to able to draw the circle as a first argument. 10:05.110 --> 10:07.750 This gizmo straw where sphere. 10:07.750 --> 10:11.590 It's going to take the position from where you want to draw the circle. 10:11.590 --> 10:16.870 So I'm going to pass transform dot position means the center position of our anime game object. 10:16.910 --> 10:19.270 And the second thing it's going to take the radius. 10:19.270 --> 10:24.830 So we're going to pass this attack range because with this attack range, we're just creating our radius 10:24.830 --> 10:28.470 or that circle with this much radius as you can see. 10:28.510 --> 10:31.630 So as a second argument I'm going to pass my attack range. 10:31.630 --> 10:33.710 And let's close that up with semicolon. 10:33.710 --> 10:39.470 And if you want to choose a different color then before you draw the circle you can choose the color 10:39.470 --> 10:42.950 as well by using this gizmos dot color. 10:42.950 --> 10:45.670 And you can set the color you would like to go with. 10:45.670 --> 10:49.550 So I'm going to set equal to something like color dot red. 10:49.790 --> 10:52.070 And you can choose any color that you like. 10:52.350 --> 10:55.230 And let's save our script and head over to unity. 10:55.750 --> 11:01.950 So uh, we will see as soon as our enemy script is gonna get compiled, we will be able to see that 11:01.950 --> 11:08.110 circle will be drawn from this enemy GameObject center position with this much of a radius, which is 11:08.150 --> 11:09.990 attack range, as you can see. 11:10.110 --> 11:17.830 And as soon as gets our, uh, our enemy script gets compiled, we can see the circle has been drawn 11:17.830 --> 11:22.270 from this enemy center position, and we can play around with this attack range. 11:22.270 --> 11:25.470 Basically attack radius you can call as well. 11:25.470 --> 11:27.750 So I'm going to set something like this much. 11:28.110 --> 11:30.750 And I guess it would be nice. 11:30.750 --> 11:34.550 So let's select the console top console tab in order to see the message. 11:34.550 --> 11:38.310 And let's click on this play button in the top to play our game. 11:39.630 --> 11:45.230 So as soon as this player game object is going to collide with this enemy circle or this circle, that 11:45.230 --> 11:48.430 message just going to pop up right away says attack on player. 11:48.470 --> 11:54.230 As you can see, the message just getting pop up every single time because we're doing inside that update 11:54.230 --> 11:54.990 function. 11:54.990 --> 12:01.270 So let's get out of play mode and what it's need to do this enemy game object, it's need to attack 12:01.270 --> 12:06.750 on this player game object, or it's basically need to shoot on this player game object. 12:06.750 --> 12:11.710 I hope you get the idea that how you can do it or how you can just do that. 12:11.710 --> 12:14.190 Let's go to overheads and then apply all. 12:14.190 --> 12:21.070 So the changes we made over here, it's going to be saved into this enemy one GameObject prefab as well. 12:21.070 --> 12:24.470 And I'm going to press down Ctrl S in order to save my project.
