WEBVTT 00:06.810 --> 00:07.810 Welcome back. 00:07.830 --> 00:14.730 Now we have some basic functionality for our melee attackers, but our ranged attackers do not really 00:14.730 --> 00:17.520 do anything when they're supposed to attack. 00:17.550 --> 00:19.620 Now, if we go into AI. 00:19.650 --> 00:26.070 Behaviour tree and open our behaviour tree, we know that if they are ranged attackers, we do get to 00:26.070 --> 00:32.970 the ranged attack behavior tree task and if we open that we see that we call try activate abilities 00:32.970 --> 00:39.210 by tag passing the attack tag which is just set to abilities dot attack. 00:39.390 --> 00:45.660 So if those ranged attackers had some abilities that have that tag, they would be activated. 00:45.690 --> 00:51.180 So what does our Slingshot goblin really need to do in its ability? 00:51.210 --> 00:53.460 Well, it's going to launch a projectile. 00:53.460 --> 00:56.690 It's presumably going to launch a rock, right? 00:56.700 --> 01:00.240 Well, that's basically what our ora projectile spell does. 01:00.270 --> 01:01.920 It launches a projectile. 01:01.920 --> 01:05.460 It does other things, too, like play an attack montage and so on. 01:05.460 --> 01:11.350 But really, at the base, the C plus plus class for it has things that we could use. 01:11.380 --> 01:18.670 Let's go into ora projectile spell dot CP Now all that the C plus plus class has is a blueprint callable 01:18.670 --> 01:23.410 spawn projectile function and it takes a projectile target location. 01:23.410 --> 01:32.290 So on the server it's going to get the socket location using the combat interface function, get combat 01:32.290 --> 01:36.780 socket location and it's going to search for the weapon socket. 01:36.790 --> 01:43.960 So this ora projectile spell is really specific to the weapon socket unless of course we changed it. 01:43.960 --> 01:50.230 So that spawn projectile could take a gameplay tag that we can pass in to get combat socket location 01:50.230 --> 01:52.150 and get, say, a hand socket. 01:52.150 --> 01:56.890 If we wanted our enemies to throw something from their hand, for example. 01:56.920 --> 02:02.050 Now it sets the rotation using the projectile target location. 02:02.050 --> 02:08.200 So if it's aiming at something, if it has a location that we pass in that's valid, it's going to aim 02:08.200 --> 02:10.930 that projectile in that direction. 02:10.930 --> 02:17.650 It's then going to set the spawn, transform, spawn the projectile, but using spawn actor deferred. 02:17.650 --> 02:24.310 And then it sets a bunch of things on the effect context as well as set the gameplay effect spec based 02:24.310 --> 02:26.040 on the damage effect class. 02:26.050 --> 02:33.520 After that, it loops through all of its damage types in the ability and performs a lookup based on 02:33.520 --> 02:40.650 their curve table and then sets the damage effect spec handle and finishes spawning the projectile. 02:40.660 --> 02:44.800 This is all stuff that we could use for our slingshot enemy. 02:44.920 --> 02:51.280 So since we have the basic spawn projectile function that we need, we can create a blueprint based 02:51.280 --> 02:56.110 on ora projectile spell and use it for our ranged attack enemies. 02:56.110 --> 02:57.820 So I'd like to do that. 02:58.270 --> 03:04.660 So I'm going to go into Blueprint's ability system and already I'm starting to see a need to separate 03:04.660 --> 03:07.450 this into Ora and enemies. 03:07.450 --> 03:13.690 So I'm going to make a new folder called Ora and a new folder called Enemies. 03:15.160 --> 03:19.700 Or just enemy and we'll leave data where it is. 03:19.720 --> 03:26.950 But for gameplay abilities we have to hit react, melee attack and test gameplay ability. 03:26.980 --> 03:29.730 These belong in enemy. 03:29.740 --> 03:34.960 So Enemy is going to have a new folder called Abilities. 03:34.990 --> 03:38.290 We'll go ahead and make a new folder called effects as well. 03:38.680 --> 03:43.030 And back out into ability system gameplay abilities. 03:43.030 --> 03:47.260 We'll take these three and we'll put them in enemy abilities. 03:49.090 --> 03:55.060 And we'll move here and now Ora can get the fire gameplay ability. 03:55.300 --> 04:00.640 So fire can go into Ora, which should get its own abilities folder. 04:00.640 --> 04:03.850 So Ora gets an abilities. 04:04.870 --> 04:07.060 We'll also make an effects folder. 04:07.780 --> 04:15.010 So back to ability system to gameplay abilities, we'll take fire and we'll put it in Ora abilities 04:15.460 --> 04:16.480 move here. 04:16.750 --> 04:20.860 And now we don't need the gameplay abilities folder that's empty. 04:21.010 --> 04:26.260 Let's go to gameplay effects and we have g damage and g hit react. 04:26.290 --> 04:36.130 Damage is used by basically both ora and enemies, but we can place it in the ora effects folder. 04:36.130 --> 04:37.090 That's fine. 04:37.360 --> 04:40.630 And g hit react can go in enemy effects. 04:41.190 --> 04:46.800 And then we have default attributes both for aura and enemy and then of course, ones that are used 04:46.800 --> 04:49.680 by both for ones that are used by both. 04:49.680 --> 04:52.020 We'll put those in the aura effects. 04:53.400 --> 04:57.240 And aura has aura, primary and secondary. 04:57.240 --> 05:01.200 Those will go in aura effects move here and now. 05:01.200 --> 05:03.990 This aura folder is empty. 05:04.020 --> 05:09.510 We have enemy with the enemy primary attributes for each enemy class. 05:10.430 --> 05:12.590 We'll go ahead and move that into effects. 05:12.590 --> 05:14.240 And we have the curve tables. 05:14.240 --> 05:17.270 Those can also be moved into enemy effects. 05:18.230 --> 05:20.330 And now enemy is an empty folder. 05:20.330 --> 05:21.530 We can delete it. 05:21.530 --> 05:26.210 And then secondary attributes enemy and secondary attributes test. 05:26.240 --> 05:28.190 Those can go into enemy effects. 05:28.190 --> 05:29.630 Move here and now. 05:29.660 --> 05:35.030 Default attributes is empty and now ability system gameplay effects is empty. 05:35.030 --> 05:38.150 We'll delete that and we'll leave the gameplay tags there. 05:38.420 --> 05:45.830 So now ability system has aura and enemy and an enemy we can go to abilities and we can add another 05:45.860 --> 05:47.570 gameplay ability. 05:47.690 --> 05:54.110 So I'm going to right click and go to Blueprint class and search for Aura projectile spell. 05:55.940 --> 06:03.920 Because this is going to be a projectile spell and we're going to call this G a underscore ranged attack. 06:04.550 --> 06:12.950 So now we have a ranged attack gameplay ability, and this is going to be what our Slingshot goblin 06:12.950 --> 06:14.450 is going to use. 06:14.480 --> 06:20.240 Now it needs a projectile to spawn and it needs a damage effect class as well as damage type. 06:20.240 --> 06:24.860 So we have quite a few things we're going to need to set for this. 06:24.890 --> 06:33.530 We also need the ability tag set to that attack tag in order for the attack task to be able to activate 06:33.530 --> 06:37.610 it because it's activating abilities by abilities attack. 06:38.150 --> 06:38.540 Okay. 06:38.540 --> 06:44.390 So we have a number of things to set here, and we're going to start in the next video by creating a 06:44.390 --> 06:47.640 projectile class for our slingshot enemy. 06:47.660 --> 06:50.270 So great job and I'll see you soon.
