WEBVTT 00:00.320 --> 00:02.420 Welcome to the next quest. 00:02.780 --> 00:09.140 Now we're going to want to play the ranged attack montage, so I'd like you to handle that in our ranged 00:09.140 --> 00:10.250 attack ability. 00:10.370 --> 00:12.180 Go ahead and play that montage. 00:12.200 --> 00:16.430 Make sure you get it similarly to how we did our melee attack. 00:16.460 --> 00:22.460 Now, I'd like you to also take care of motion warping, so make sure that our ranged attacker will 00:22.460 --> 00:27.990 rotate towards aura when shooting and as a bonus, respond to the event. 00:28.010 --> 00:31.160 We know that we're sending a gameplay event from our montage. 00:31.190 --> 00:34.970 If you feel so inclined, respond to that event. 00:34.970 --> 00:41.450 And if you really want to get ambitious, see if you can get the correct weapon socket location. 00:41.450 --> 00:47.540 Taking into account all the things you need to do there and draw a debug sphere at the slingshot pouch. 00:47.540 --> 00:52.760 So lots of additional optional mini challenges in there for you as well. 00:52.760 --> 00:56.480 So pause the video and conquer this quest now. 00:59.870 --> 01:00.560 All right. 01:00.560 --> 01:09.020 So I'm here in my ranged attack, and I think I'd like to just move this draw debug sphere up and out 01:09.020 --> 01:11.390 of the way just in case I want to use it later. 01:11.390 --> 01:14.510 But for now, I'd like to play a montage. 01:14.540 --> 01:22.220 Now, if I look at my melee attack, I'll see that I'm getting the avatar actor and using the interface 01:22.220 --> 01:24.380 function get combat target. 01:24.380 --> 01:32.060 And from that combat target we're getting it's actor location and using that to update the facing target 01:32.090 --> 01:36.410 using the combat interface function update facing target. 01:36.440 --> 01:40.250 Let's see if we can do that same thing here in our range attack. 01:40.250 --> 01:48.290 So first I'm going to get Avatar actor from actor info and I'm going to get its combat target. 01:48.770 --> 01:51.020 So I'm going to call get combat target. 01:51.050 --> 01:56.630 This requires that actor and it returns an actor object reference. 01:56.630 --> 02:03.060 So we're going to get that combat target and I'm going to get its location with get actor location. 02:03.240 --> 02:10.410 Now, next, we can update the facing target by calling update, facing target and passing in the target 02:10.410 --> 02:11.490 location. 02:11.490 --> 02:17.280 But make sure that this target is actually the owner of the interface. 02:17.280 --> 02:17.870 Right. 02:17.880 --> 02:20.560 We don't want to pass in the combat target. 02:20.580 --> 02:22.920 It's a little confusing that this is called Target. 02:22.920 --> 02:24.480 But look at our melee. 02:24.510 --> 02:26.970 You'll see that we're calling update facing Target. 02:26.970 --> 02:30.210 And notice I didn't have to cast to the combat interface. 02:30.210 --> 02:37.770 That's because if we go back to our combat interface here in public interaction, Combat Interface update, 02:37.770 --> 02:44.430 facing Target is actually a blueprint, implementable blueprint callable, and we can just call it directly 02:44.430 --> 02:45.180 like this. 02:45.180 --> 02:51.230 So after updating the facing target, we can then do what we did in the melee attack. 02:51.240 --> 02:55.170 We can get the attack montages from the combat interface. 02:55.170 --> 02:56.670 So let's do that. 02:56.670 --> 02:59.640 We're going to call get attack montages. 02:59.670 --> 03:03.660 We're going to plug in the Avatar actor. 03:04.020 --> 03:06.780 So I'm going to duplicate that, plug that in. 03:06.780 --> 03:11.070 And we now want a random attack montage. 03:11.070 --> 03:13.980 Now this right here is a little bit messy. 03:13.980 --> 03:20.550 I'd really like for our aura damage gameplay ability to be able to do that for us. 03:20.550 --> 03:28.860 Just take in an array of this type and return one of them at random and perhaps return an empty struct 03:28.860 --> 03:33.900 for the tagged montage if this array is empty or doesn't contain anything. 03:33.900 --> 03:39.930 So I think that is something I'd like to create a blueprint callable function for so that we don't have 03:39.930 --> 03:43.500 to just copy all these nodes and paste them in here. 03:43.620 --> 03:52.410 So for that reason I'm going to go back into our C plus plus ability and ability system abilities and 03:52.410 --> 03:57.860 I'm going to add this to aura damage gameplay ability because it has the damage capabilities. 03:57.870 --> 04:06.090 I'm going to add a new function here and this function is just going to take in an array of tagged montage 04:06.090 --> 04:11.130 structures and it's going to return one of those tagged montages. 04:11.130 --> 04:14.910 So it'll return an F tagged montage. 04:14.940 --> 04:26.490 I'm going to add the include for that and call this get random tagged montage from array and it'll take 04:26.520 --> 04:31.020 a const t array of f tagged montages. 04:32.530 --> 04:35.020 And it'll take it in by const reference. 04:35.020 --> 04:37.330 And I'll call this tagged montages. 04:40.280 --> 04:46.760 And this will be a new function and we can make this blueprint pure. 04:47.580 --> 04:50.370 So let's go ahead and generate the definition for this. 04:50.370 --> 04:52.130 And it's going to be quite simple. 04:52.140 --> 04:56.220 It's going to do exactly what our blueprint nodes are doing. 04:56.220 --> 05:01.020 It's going to check the length of the array, make sure it's not zero. 05:01.170 --> 05:12.060 So we're going to say if tagged montages dot num is greater than zero and at the very end, we're just 05:12.060 --> 05:15.750 going to return an F tagged montage that's empty. 05:16.590 --> 05:23.430 But if the tagged montage is array is not empty, well then what we're going to do is we're going to 05:23.430 --> 05:28.530 get the length of the array minus one and get a random integer. 05:28.530 --> 05:38.340 So we're going to say int 32, this could be const, actually we'll call it selection equals F math 05:38.340 --> 05:40.320 rand range. 05:43.060 --> 05:45.610 Rand range needs a minimum and a maximum. 05:45.610 --> 05:55.210 We're going to go from a minimum of zero to tagged montages, dot numb minus one. 05:55.750 --> 06:03.340 And then we're going to return tagged montages, indexing it with selection. 06:04.150 --> 06:09.130 So now we have this nice function we can call and of course it can be const. 06:09.130 --> 06:13.270 So let's go ahead and just make that a const function. 06:15.960 --> 06:16.830 There we go. 06:16.830 --> 06:21.150 And this blueprint, pure function can be used instead of all those nodes. 06:21.150 --> 06:27.930 So I'm going to close out of the editor saving all my progress and then just go ahead and launch again. 06:28.050 --> 06:29.790 I'm just going to click Run. 06:30.430 --> 06:33.650 And we'll go ahead and open up our asset editors. 06:33.670 --> 06:42.250 I'm going to go back to my melee and use my get random tagged montage from array and use this instead 06:42.250 --> 06:42.810 now. 06:42.820 --> 06:45.280 So I'm going to plug that array straight in. 06:45.640 --> 06:52.060 Target is self and the return value is the actual tagged montage that we're going to store. 06:52.060 --> 06:57.460 And I don't need the rest of these nodes and I don't actually want my branch either. 06:57.460 --> 07:00.550 So I'm going to delete any ability, delete the branch. 07:01.660 --> 07:03.220 And delete these nodes. 07:03.220 --> 07:05.020 And this is a lot cleaner. 07:05.530 --> 07:09.800 Okay, So we're going to do something similar here in the ranged attack. 07:09.820 --> 07:12.400 So here's my GA ranged attack. 07:12.440 --> 07:15.440 Looks like it got stuck on the other side of all those tabs. 07:15.460 --> 07:21.910 So after getting attack montages, we're going to call get random tagged montage from array. 07:22.540 --> 07:27.130 Get random tagged montage from array. 07:27.850 --> 07:36.160 Hooking in that array and the return value can be promoted to a variable called tagged montage. 07:38.590 --> 07:43.670 Once we have that, we can go ahead and play a montage and wait. 07:43.690 --> 07:48.790 So I'm going to use that ability task play montage and wait. 07:51.630 --> 07:53.930 Using the montage in our tagged montage. 07:53.940 --> 07:55.440 So we're going to break it. 07:56.470 --> 07:58.630 And expose that montage. 07:58.660 --> 08:01.150 I'm going to uncheck Stop when ability Ends. 08:01.150 --> 08:07.360 I'd like that montage to keep playing until it's over and we have the montage tag as well. 08:07.360 --> 08:14.320 So that has to do with kind of a bit of the bonus challenge where we wait for the gameplay event. 08:14.320 --> 08:22.690 For now though, let's just make sure that play montage and wait works and we do need our goblin slingshot 08:22.720 --> 08:24.640 to have its attack montages. 08:24.640 --> 08:30.550 I know I added it, but I'm going to show you that I'm double checking it just to make sure. 08:30.580 --> 08:35.620 So we should be able to see that montage get played in our ranged attack. 08:35.620 --> 08:38.830 Let's go ahead and just save all and try that. 08:40.590 --> 08:43.530 So here are the ranged attackers hanging back. 08:43.860 --> 08:45.600 And there they are. 08:46.110 --> 08:49.530 They are attacking that walls in the way. 08:49.530 --> 08:51.270 I'm going to go ahead and get rid of it. 08:51.420 --> 08:55.500 And now we should be able to see those ranged attackers. 08:55.500 --> 09:01.320 And yes, they are attacking and in fact, their motion warping looks like it's working as well. 09:01.350 --> 09:08.550 They're orienting towards our enemy or towards their enemy, I should say, as they attack with their 09:08.550 --> 09:09.330 slingshots. 09:09.330 --> 09:10.950 So that's looking great. 09:10.980 --> 09:17.730 Now for the optional bonus part of the challenge, we could wait for a gameplay event so we can drag 09:17.730 --> 09:21.060 right off of this use wait gameplay event. 09:23.740 --> 09:29.260 And the tag that we're going to wait for is the tag associated with our montage. 09:29.290 --> 09:31.060 So let's reroute this. 09:32.150 --> 09:33.650 Wire around. 09:35.270 --> 09:38.360 And drag it in for our wait gameplay event. 09:38.450 --> 09:40.700 Make sure that it's matching exact. 09:40.700 --> 09:47.150 And just like in our melee attack, once the event is received, we can get the combat socket location 09:47.150 --> 09:53.030 using that tag and we're going to just draw a debug sphere for now. 09:53.030 --> 09:57.950 So on event received, we're going to call get combat socket location. 09:58.770 --> 10:02.340 Passing in the tag for the montage tag there. 10:02.910 --> 10:05.160 I'll go ahead and reroute that node right there. 10:05.310 --> 10:07.320 Now we need a target for this. 10:07.320 --> 10:12.630 And just like in Melee, we could use get Avatar actor from actor info. 10:12.660 --> 10:14.700 Let's go ahead and use that. 10:14.820 --> 10:18.480 Get avatar actor from actor info. 10:19.630 --> 10:26.530 We're getting the combat socket location, which means we need to make sure that our goblin slingshot 10:26.560 --> 10:29.860 has its weapon tip socket name set. 10:29.890 --> 10:36.610 Now, to make this easy so we don't forget in the future, I could just set the base enemy weapon, 10:36.610 --> 10:41.670 tip socket name to tip socket and just use that for all of my enemies. 10:41.680 --> 10:43.180 So I'd like to do that. 10:43.180 --> 10:51.220 I'm going to go to Blueprints Character BP Enemy base and search for weapon tip socket name and set 10:51.220 --> 10:53.110 that to tip socket. 10:54.360 --> 11:00.030 And that way in all of my child classes, they're set to tip socket unless I overwrite them. 11:00.030 --> 11:08.010 But now we are using tip socket for all of our enemies and that is going to ensure that things work 11:08.040 --> 11:11.200 as long as our enemies are using that socket name. 11:11.220 --> 11:17.400 Now, first, I should make sure I'm not breaking my spear goblin, so I'm going to go into enemies 11:17.430 --> 11:22.530 under assets, goblin, Spear and open my static mesh spear. 11:22.530 --> 11:24.900 And it says it's called tip socket. 11:24.900 --> 11:30.060 And we renamed the base enemies weapon tip socket name to tip socket. 11:30.060 --> 11:31.650 So that works. 11:31.680 --> 11:34.770 Now that works if everything is called tip socket, right? 11:34.770 --> 11:40.050 But if we look at the static mesh for the slingshot, it has a bone called pouch. 11:40.050 --> 11:42.240 We're going to need that socket. 11:42.240 --> 11:45.990 So we'll add a socket and this socket should be called tip socket. 11:46.890 --> 11:51.000 Either that or we could call it pouch socket if we wanted to. 11:51.600 --> 11:59.290 But if we do that, we do have to go into Goblin Slingshot and make sure it's called pouch socket here. 11:59.290 --> 12:06.580 So it's up to you if you want it to be called pouch socket and you just overwrite this in goblin slingshot, 12:06.610 --> 12:08.410 use tip socket for all the others. 12:08.410 --> 12:09.190 It's up to you. 12:09.190 --> 12:12.340 So if you want you can just use tip socket for everything. 12:12.340 --> 12:14.020 But it makes more sense. 12:14.020 --> 12:18.890 I think if the pouch socket is called pouch socket up to you. 12:18.910 --> 12:26.440 Now that we set that correctly in our ranged attack get combat socket location should return a socket 12:26.440 --> 12:30.300 location and I saved my draw debug sphere up here. 12:30.310 --> 12:35.830 I'm going to use that passing in the combat socket location. 12:36.530 --> 12:38.090 So that we can see that. 12:38.090 --> 12:42.740 But I'm going to change it to a red color and draw it a little smaller. 12:42.740 --> 12:49.700 Let's do 20 for the radius and let's see if we can see the combat socket location. 12:50.360 --> 12:52.070 Let's make sure that that's correct. 12:52.070 --> 12:55.760 So saving all and getting our enemies close. 12:55.760 --> 12:57.260 And there we go. 12:57.290 --> 12:58.580 They're attacking. 12:58.580 --> 13:01.850 And that combat socket location looks correct. 13:01.880 --> 13:09.170 We can really hone in on it by setting its radius to a really small value like five and seeing if it 13:09.170 --> 13:11.480 looks pretty much perfect. 13:11.480 --> 13:15.080 And yes, it does look like it's right there at the socket. 13:17.020 --> 13:17.810 On the pouch. 13:17.830 --> 13:18.730 Perfect. 13:18.940 --> 13:21.480 Okay, so we're one step closer. 13:21.490 --> 13:23.590 We're now playing our montage. 13:23.590 --> 13:27.760 We're receiving the event, we're getting the correct socket location. 13:27.760 --> 13:29.730 Everything is looking nice. 13:29.740 --> 13:33.040 We still want to spawn a rock projectile. 13:33.040 --> 13:35.020 So a couple things left. 13:35.020 --> 13:43.300 And of course, we do want our slingshot itself to be stretchy and look like that pouch is being held 13:43.300 --> 13:44.320 and released. 13:44.320 --> 13:47.200 So quite a few things left for our range attacker. 13:47.200 --> 13:48.250 We're getting there. 13:48.340 --> 13:49.240 Excellent job. 13:49.240 --> 13:52.930 I'm going to save all and I'll see you in the next video.
