WEBVTT 00:00.410 --> 00:02.360 Welcome to your next quest. 00:02.630 --> 00:08.010 In this quest, you're going to play an attack montage, so you should know how to do this. 00:08.030 --> 00:11.250 You're going to do this in our new melee attack ability. 00:11.270 --> 00:19.610 So go ahead and decide how you're going to go about making a montage and we'll go ahead and just use 00:19.610 --> 00:22.250 an attack montage for the Goblin Spear. 00:22.250 --> 00:28.550 And later, we'll work on making this ability reusable among other types of melee attackers. 00:28.550 --> 00:32.960 So for now, pause the video and conquer this quest now. 00:35.830 --> 00:38.680 Okay, we're going to want to play an attack montage. 00:38.680 --> 00:43.720 So we're going to open up our brand new gameplay ability for attacks. 00:43.810 --> 00:51.840 Let's go to Ability System in our blueprints folder, open up gameplay abilities and gar melee attack. 00:51.850 --> 00:54.840 So here in Melee Attack, we're going to play a montage, right? 00:54.850 --> 01:04.870 That means we need to use a play montage node and we're going to use the play montage and wait ability 01:04.870 --> 01:05.590 task. 01:05.590 --> 01:12.130 So for this we're just going to hardcode a montage for now, but we'll make this more versatile later. 01:12.130 --> 01:14.230 We just want to get things working for now. 01:14.230 --> 01:17.680 So for the montage to play, we need a montage, right? 01:17.680 --> 01:22.120 And we only have hit React montages for the goblins. 01:22.120 --> 01:24.490 We're going to need one for an attack. 01:24.730 --> 01:33.640 So let's go to the assets folder into Enemies Goblin and animations and spear and we have our spear 01:33.670 --> 01:34.900 goblin animations. 01:34.900 --> 01:36.530 We're going to want an attack. 01:36.530 --> 01:38.630 And here we have Attack spear. 01:38.660 --> 01:41.330 This is going to be just perfect for us. 01:41.360 --> 01:44.510 Let's make a montage based on this. 01:44.510 --> 01:46.970 So I'm going to right click on Attack Spear. 01:47.000 --> 01:55.760 We're going to use Create, Create and a montage and we're going to call this Am underscore attack Goblin 01:56.150 --> 01:57.170 Spear. 01:57.590 --> 02:04.490 And just to be consistent with my hit React, there will be no underscore between Goblin and spear. 02:04.490 --> 02:06.260 So we have an attack goblin. 02:06.260 --> 02:06.800 Spear. 02:06.830 --> 02:07.640 Right. 02:07.760 --> 02:12.410 So for now, that's all I want to do is just create this attack montage. 02:12.410 --> 02:19.250 We'll go ahead and use this in Gar melee attack and play montage and wait, we're going to use Attack 02:19.250 --> 02:22.760 Goblin Spear and just play that montage. 02:22.910 --> 02:28.070 Now, as soon as this montage has completed, I'm going to end the ability. 02:28.070 --> 02:30.920 So we're going to use end ability like this. 02:31.910 --> 02:33.860 And there we have it. 02:33.890 --> 02:35.940 Our ability plays a montage. 02:35.960 --> 02:41.990 So let's see how this works by pressing play and we'll see our goblin spear run up to us. 02:41.990 --> 02:43.900 And there we go. 02:43.910 --> 02:44.980 It's attacking. 02:44.990 --> 02:49.190 Now it moves to another location and then it attacks again. 02:50.220 --> 02:52.650 So this is looking pretty good. 02:52.920 --> 02:56.070 And there's a couple of issues. 02:56.070 --> 03:02.250 For one, I saw that the goblin is attacking not quite straight on sometimes. 03:02.250 --> 03:05.240 Sometimes it attacks with its spear off to the side. 03:05.250 --> 03:11.160 So that's something we're going to want to work on, but that's something we could fix as we've fixed 03:11.160 --> 03:12.420 this kind of issue before. 03:12.420 --> 03:18.200 With Aura, you see, if Aura is launching an ability behind her, she turns around. 03:18.210 --> 03:18.690 Why? 03:18.720 --> 03:24.440 Because she has a root motion attack animation, and we're using motion warping. 03:24.450 --> 03:26.370 How are we using motion warping? 03:26.370 --> 03:32.790 Well, we can go into blueprints, into character aura and open up aura character. 03:32.790 --> 03:40.080 And we have this event update facing Target where we're getting our motion warping component on aura, 03:40.080 --> 03:45.840 which we added on the blueprint and we're using Add or update warp target from location. 03:45.840 --> 03:51.880 So we have this event, this interface event update facing Target. 03:51.910 --> 03:56.020 Now why can't we just do this for the enemy as well? 03:56.020 --> 04:00.940 Just to remind ourselves, if we go into our combat interface, here is that event. 04:00.940 --> 04:06.460 It's a blueprint, implementable event, blueprint callable, and it's called Update facing Target, 04:06.460 --> 04:10.990 which takes an F vector by const reference called Target. 04:10.990 --> 04:15.670 So there's no reason why we can't implement this on the enemy class. 04:15.670 --> 04:23.530 And in fact, we have a base enemy blueprint that we can use BP enemy base, we can implement that interface 04:23.530 --> 04:24.550 function here. 04:24.580 --> 04:27.400 It's called Update facing Target. 04:27.430 --> 04:33.490 Now there's the function call because it's blueprint callable, and then there's the event because it's 04:33.490 --> 04:35.410 blueprint implementable event. 04:35.440 --> 04:40.780 We want the event so we can decide what happens when the function gets called for the enemy. 04:40.810 --> 04:47.410 Now, the enemy doesn't have a motion warping component like BP or a character, so we're going to need 04:47.410 --> 04:49.120 to add one to enemy base. 04:49.120 --> 04:52.660 We're going to click Add and let's search for motion warping. 04:52.660 --> 04:53.620 Here it is. 04:53.620 --> 04:59.860 We can add the motion warping component, we can drag it out and we can do what we did in Aura character 04:59.890 --> 05:04.750 add or update warp target from location choosing, facing target. 05:04.750 --> 05:05.800 So let's do that. 05:05.800 --> 05:12.280 We're going to call Add or update warp target from location and we're going to choose to use the same 05:12.280 --> 05:16.090 naming convention facing target for the warp target name. 05:16.090 --> 05:20.590 And we're going to use the target as the target location and hook that up. 05:20.590 --> 05:29.620 So now if our enemy is ever playing a root motion montage that has a motion warping notify State with 05:29.620 --> 05:35.080 facing target as the warp target name, then this is going to set that warp target. 05:35.080 --> 05:42.910 So all we need to do is call update facing target and we can make our enemies rotate to face a facing 05:42.940 --> 05:43.690 target. 05:43.690 --> 05:50.530 So let's go to our attack Goblin Spear and we can simply add a notify state with that facing target 05:50.560 --> 05:52.060 warp target name. 05:52.060 --> 05:59.110 So I'm going to go down to the notifies and rename the first track to Motion warping, and I'm going 05:59.110 --> 06:03.730 to right click on that track, add, notify state and choose motion warping. 06:03.730 --> 06:09.160 And I'm going to put this pretty close to the beginning and I'm going to grab the other end, the right 06:09.160 --> 06:14.320 hand side of it, hold shift so I can preview the animation at that point. 06:14.320 --> 06:20.320 And I'd like to warp to just about right here before the enemy starts that thrust. 06:20.320 --> 06:26.050 So we'll rotate to face the target by here and then we'll thrust at that target. 06:26.050 --> 06:33.580 So with motion warping this notify state selected, we can configure it by expanding root motion modifier 06:33.580 --> 06:35.710 and changing the warp target name. 06:35.710 --> 06:41.500 Now, back in enemy base, we see that that warp target name that we should use is facing target. 06:41.500 --> 06:45.520 So we're going to call that warp target name facing target. 06:45.610 --> 06:48.520 Now we only want to warp rotation. 06:48.520 --> 06:53.080 So what we can do is we can uncheck warp translation. 06:53.080 --> 06:58.090 Now we only have warp rotation and for rotation type I want facing. 06:58.090 --> 07:01.480 So we'll rotate to face that target. 07:01.480 --> 07:04.210 So now we're all set up to use motion warping. 07:04.210 --> 07:11.350 The only thing left is to actually call this function update facing target with an appropriate target 07:11.350 --> 07:12.100 to face. 07:12.100 --> 07:14.710 So what do we want to rotate to face? 07:14.710 --> 07:22.150 Well, if we're in melee attack on this enemy, we want to rotate to face aura, the thing that this 07:22.150 --> 07:26.890 enemy is trying to attack now, it doesn't really have a reference to aura. 07:26.890 --> 07:31.750 It needs some kind of variable for a combat target. 07:31.750 --> 07:38.890 So what we're going to do is add a combat target to the enemy so that it can rotate to face that combat 07:38.890 --> 07:39.700 target. 07:39.700 --> 07:42.940 And then we need to access that combat target here. 07:42.940 --> 07:45.940 We also need to set that combat target somehow. 07:45.940 --> 07:49.360 So in the next video, we're going to add a combat target. 07:49.400 --> 07:56.290 Target variable to our enemy so that it can use that combat target to motion warp towards that target, 07:56.290 --> 08:01.720 to face that target every time the enemy attacks with a melee attack. 08:01.720 --> 08:03.190 And we'll do that next. 08:03.190 --> 08:05.290 So great job and I'll see you soon.
