WEBVTT 00:07.080 --> 00:08.190 Welcome back. 00:08.190 --> 00:12.480 Now we have a few offensive abilities, and by a few I mean three. 00:12.480 --> 00:18.330 And we're going to make one more because with these first three I think we have a pretty good example 00:18.330 --> 00:20.940 of three very different abilities. 00:20.940 --> 00:22.770 But I'd like to do at least one more. 00:22.770 --> 00:24.900 It's going to be one of the fire abilities. 00:24.900 --> 00:31.080 And this will give us at least one more example of how to make a gameplay ability that's different than 00:31.080 --> 00:35.490 the others, as we have several sort of categories, right? 00:35.490 --> 00:43.530 We have the launching a projectile category, we have the beam type spell, and we have something that's 00:43.530 --> 00:50.700 really completely different and uses a whole bunch of target points that we can use to spawn a bunch 00:50.700 --> 00:58.080 of different particles, as well as the ability to have a decal, a magic circle that we can use to 00:58.080 --> 00:58.500 aim. 00:58.500 --> 01:02.280 So that's quite a bit different than our other ability types. 01:02.280 --> 01:07.530 But I'd like to make one more, and this one is going to be right here. 01:07.530 --> 01:12.000 The next fire spell up and I'm going to call it fire Blast. 01:13.540 --> 01:15.820 So we can go ahead and get started. 01:15.820 --> 01:22.960 It's going to be an aura damage gameplay ability, and I'm going to go ahead and add a new C plus plus 01:22.960 --> 01:23.710 class for it. 01:23.710 --> 01:27.760 In abilities, I'm going to find Aura Damage gameplay ability. 01:30.110 --> 01:33.110 I'm going to create a C plus plus class based on it. 01:33.110 --> 01:37.190 And I'm going to call this aura Fireblast. 01:37.550 --> 01:39.620 Let's go ahead and create this class. 01:40.980 --> 01:42.870 And we'll open it up here. 01:45.400 --> 01:48.940 Here's the cpp file and here's the header file. 01:49.390 --> 01:49.720 Okay. 01:49.720 --> 01:53.320 So where do we get started and what is this ability going to do. 01:53.350 --> 01:58.690 Well I think a good place to get started would be the description because that's where we can decide 01:58.690 --> 01:59.620 what it does. 01:59.620 --> 02:04.570 And at the same time implement that spell description for our spell menu. 02:04.570 --> 02:07.030 And we can kill two birds with one stone. 02:07.300 --> 02:13.300 Now again with the descriptions, I'm going to turn to one of my other spells. 02:13.300 --> 02:16.720 I'm going to turn to Aura Firebolt. 02:16.840 --> 02:20.170 And we're going to use the Aura Firebolt as an example. 02:20.170 --> 02:26.080 So I'm going to copy get description and get next level description as well. 02:27.320 --> 02:29.390 And we'll override these. 02:29.390 --> 02:31.160 I'll need a public section. 02:33.280 --> 02:36.880 And we have these two functions and we can generate definitions for them. 02:42.730 --> 02:50.230 Okay so clearing these out I'm going to go into Aura Firebolt and just copy the contents of Getdescription 02:50.230 --> 02:50.770 here. 02:53.550 --> 02:56.370 And we'll paste them into our fireblast. 02:56.790 --> 02:59.640 Now, the first thing I'm going to do is change the title. 02:59.640 --> 03:02.160 This is going to be Fireblast. 03:02.850 --> 03:08.670 And I'd like to show the spell level, the mana cost, and the cooldown, and let's decide what it's 03:08.670 --> 03:09.750 going to do. 03:09.750 --> 03:17.970 I'd like Aura Fireblast to spawn some fireballs, kind of like Firebolt, but I'd like these fireballs 03:17.970 --> 03:19.890 to fly out in all directions. 03:19.890 --> 03:24.300 So we're really going to spawn a whole bunch of fireballs all at once. 03:24.600 --> 03:27.450 And for that we're going to need a number of fireballs. 03:27.450 --> 03:32.280 Now for Firebolt, we're going to call them fire bolts, and for Fireblast, I'm going to call them 03:32.280 --> 03:35.970 fireballs, just to have a distinction between the two. 03:35.970 --> 03:37.230 So we know they're different. 03:37.440 --> 03:43.440 So I'm going to make a protected section and I'm going to add an int32 called NUM Fireballs. 03:43.440 --> 03:44.820 And I'm going to do a bunch of them. 03:44.820 --> 03:46.320 I'm going to set this to 12. 03:46.320 --> 03:52.290 But we'll make this, of course, a uproperty that we can change from within our blueprint. 03:52.290 --> 03:58.320 We'll put it in edit defaults only in the category of Fire Blast. 03:58.680 --> 03:59.160 Okay. 03:59.160 --> 04:01.170 So we have a num fireballs as well. 04:01.170 --> 04:08.040 So right here for our description I'm just going to say launches space. 04:08.040 --> 04:10.500 And then I'm going to close this off. 04:11.900 --> 04:14.870 Like this and get rid of this line. 04:15.850 --> 04:19.930 And we're going to say how many of these we're going to launch. 04:19.960 --> 04:23.500 So right here after launches we're going to have percent D. 04:23.590 --> 04:30.490 And I'm going to add a comment here that says number of fireballs. 04:31.310 --> 04:35.630 And just after cool down, I need to add that it's going to be numb. 04:37.040 --> 04:38.270 Fireballs. 04:39.190 --> 04:42.580 So we're going to say launches numb fireballs. 04:42.580 --> 04:44.770 And I'm going to copy this line here. 04:45.500 --> 04:49.610 And for the text after the num fireballs. 04:49.610 --> 04:51.500 I'll just put the space right there. 04:51.530 --> 04:54.650 I'm going to say fireballs. 04:54.710 --> 05:03.740 I don't need this to be capital fireballs in all directions, each coming back and and it's time for 05:03.740 --> 05:05.480 a new line at this point. 05:07.820 --> 05:18.110 I'll put a space after and and we'll say exploding upon return, causing space. 05:18.110 --> 05:20.060 And then we have damage down here. 05:20.060 --> 05:23.150 Fire damage with a chance to burn. 05:23.150 --> 05:28.430 And actually I'm going to say radial fire damage with a chance to burn. 05:28.430 --> 05:33.950 So we can use radial damage with a falloff here so we can cause radial fire damage. 05:33.950 --> 05:40.820 Now, I personally am making the decision to just launch 12 fireballs. 05:40.820 --> 05:45.710 I mean, of course we could change this from 12, but I don't want to scale that by my level. 05:45.710 --> 05:51.170 I just want it to always be 12 and we'll just scale the damage up with our curve table. 05:51.170 --> 05:54.020 So my description doesn't need an else case. 05:56.210 --> 05:59.180 And we also don't need to check if the level is one. 05:59.180 --> 06:01.700 I'm just going to return this definition. 06:02.630 --> 06:04.010 Regardless of the level. 06:04.010 --> 06:06.920 So I'm going to remove that if statement there. 06:07.130 --> 06:11.330 Now for our next level description we can paste it in here. 06:11.330 --> 06:13.700 This can now say next level. 06:16.060 --> 06:18.040 And it's going to be the same thing. 06:18.040 --> 06:23.080 So really we could just call get description. 06:24.320 --> 06:29.900 And return that so we can just return, get description and pass in level. 06:29.900 --> 06:33.290 We could do that because I don't really plan on it being any different. 06:33.290 --> 06:38.750 So I'm just going to be efficient not lazy efficient and do that. 06:39.230 --> 06:39.710 Okay. 06:39.710 --> 06:41.780 So we have an aura fire blast. 06:41.780 --> 06:46.850 In addition to this I'm going to need a function to spawn those fireballs. 06:47.330 --> 06:52.430 However we're going to need a fireball class to spawn, so we'll do that next. 06:52.430 --> 06:57.500 But before we go into all that, let's just compile and test out things. 06:57.500 --> 07:03.140 Let's get everything tied together in our system and make sure that we can see this spell description 07:03.140 --> 07:04.130 in our menu. 07:05.350 --> 07:07.210 Okay, so we're back in the editor. 07:07.210 --> 07:10.480 We're going to make a blueprint based on our new gameplay ability. 07:10.480 --> 07:15.610 So we're going to go into blueprints ability system, aura abilities and fire. 07:15.610 --> 07:18.640 And we're going to need a new folder in fire aren't we. 07:18.640 --> 07:21.340 We're going to call this one Fire Blast. 07:21.910 --> 07:24.940 Now let's open Fire Blast and let's make a new blueprint. 07:24.940 --> 07:29.110 And we're going to search for Aura Fire Blast. 07:29.620 --> 07:30.520 Here it is. 07:30.520 --> 07:34.750 I'm going to select it and call this GA Fire Blast. 07:35.790 --> 07:37.260 And we can open it up. 07:37.680 --> 07:43.110 Now, the first thing we need at least the first thing I think of is an ability tag, which we could 07:43.110 --> 07:46.680 have made while we were in C plus plus, but we can go back and make it. 07:46.680 --> 07:51.420 Now I'm just going to close the editor and open aura gameplay tags for that. 07:53.250 --> 08:01.230 So here's or a gameplay tags and I'm going to make my new ability tag just under Arcane shards. 08:01.230 --> 08:07.500 It's going to be called Abilities Fire fire Blast. 08:07.500 --> 08:08.730 And why not? 08:08.730 --> 08:10.890 Let's put this just under Firebolt. 08:10.890 --> 08:16.650 So the fire abilities are together and we can go ahead and make the gameplay tag. 08:17.330 --> 08:18.740 Here's Firebolt. 08:18.740 --> 08:20.360 We can copy that. 08:20.810 --> 08:22.880 We can paste it and make. 08:22.910 --> 08:23.180 Aurora. 08:23.180 --> 08:23.810 Fire. 08:23.810 --> 08:24.380 Fire. 08:24.380 --> 08:25.400 Blast. 08:28.450 --> 08:35.830 And all we need to change is Firebolt now becomes fireblast and we have the tag and we can compile and 08:35.830 --> 08:36.940 we can launch again. 08:38.140 --> 08:38.590 Okay. 08:38.590 --> 08:40.540 So I'm going to get my ability back, open. 08:40.540 --> 08:44.320 Open the full blueprint editor and add my ability tag here. 08:44.320 --> 08:47.740 So it's going to be abilities fire fire blast. 08:47.740 --> 08:48.910 And there we go. 08:49.270 --> 08:53.320 And here we see our num fireballs and we have a damage effect class. 08:53.320 --> 08:56.110 We could go ahead and set that to GE damage. 08:56.110 --> 08:57.400 That's totally fine. 08:57.400 --> 09:00.490 But we're going to set the other parameters soon. 09:00.490 --> 09:07.150 But I just want to tie things together to make sure that we can see this in our spell menu, because 09:07.150 --> 09:08.260 right now we can't. 09:08.260 --> 09:08.740 Right. 09:08.740 --> 09:10.810 So we're going to need to do that. 09:11.080 --> 09:12.670 So let's do it. 09:12.670 --> 09:21.040 That means we need to go into blueprints ability system data and open ability info and add a new element 09:21.040 --> 09:26.260 to our array here for our new ability, so we can set its ability tag first. 09:26.260 --> 09:30.040 That's going to be abilities fire fire blast. 09:30.040 --> 09:32.320 We don't have a cooldown tag yet. 09:32.320 --> 09:33.940 We have an ability type, though. 09:33.940 --> 09:39.790 We know it's offensive, and if we open the icon we can search for fire and look at this. 09:39.790 --> 09:44.410 We have a fire blast and we can go to it and see that this is what it looks like. 09:44.620 --> 09:47.020 So there's our Fire blast icon. 09:48.280 --> 09:51.910 And I'm going to use the same background material as Firebolt. 09:51.910 --> 09:58.840 In other words, I'm going to search for my fire and here's fire skill BG, and I'll just use that same 09:58.840 --> 10:01.240 background material for all fire spells. 10:01.240 --> 10:06.580 I'm going to set the level requirement to two and the ability to gar fire blast. 10:06.580 --> 10:08.650 And for now, that's all we have. 10:08.650 --> 10:15.550 I'm going to go ahead and minimize index five and keep this one open and save ability info. 10:15.550 --> 10:18.700 And with that we have fire blast. 10:18.850 --> 10:21.070 So that's the first thing we need to do. 10:21.130 --> 10:29.650 The next thing we need to do is go into our content blueprints UI and open spell menu and get our offensive 10:29.650 --> 10:34.960 spell tree and decide which of these icons needs our ability tag. 10:34.960 --> 10:37.060 I'm going to set it to this one here. 10:37.060 --> 10:41.560 I'm going to search for ability Tag and set this one to Fire Blast. 10:42.440 --> 10:47.630 So with that, this spell has fireblast assigned to it. 10:47.630 --> 10:52.880 And if we go ahead and click on it, we'll see the spell is locked until level two because it now has 10:52.880 --> 10:56.900 a valid spell, whereas the others are just empty because there's nothing there. 10:57.920 --> 10:59.510 Now we can level up. 10:59.510 --> 11:02.810 I'm going to go ahead and just gain some experience. 11:03.390 --> 11:04.740 And open up. 11:04.740 --> 11:12.720 And here we see Fireblast and there's our spell description, and we see that it causes zero damage 11:12.720 --> 11:14.010 because we haven't set that. 11:14.010 --> 11:16.710 It has a mana cost of zero and a cooldown of zero. 11:16.710 --> 11:19.800 We haven't set those either, but everything else works. 11:20.420 --> 11:23.570 And if we spend a point on it, here's what it looks like. 11:23.570 --> 11:25.100 We can equip it as well. 11:25.750 --> 11:31.360 There's what it looks like there and we can activate it, but it doesn't do anything yet. 11:31.360 --> 11:34.030 We just have an empty ability. 11:34.030 --> 11:35.890 But this is a good start. 11:35.890 --> 11:42.790 And in the next video, we'll go ahead and set up some of the things that a basic spell needs, like 11:42.790 --> 11:45.100 manacost, cooldown and things like that. 11:45.100 --> 11:50.860 And then we can move on to actually implementing our fire blast effect. 11:51.040 --> 11:56.950 And before we wrap up, I'm actually noticing that being lazy and reusing my description for the next 11:56.950 --> 12:02.140 level description actually doesn't quite work, because this needs to be next level here. 12:02.140 --> 12:07.270 As the others say, next level in that bottom menu and the scroll box. 12:07.270 --> 12:12.100 Now you could pass that string in as an input parameter if you want it to be more efficient. 12:12.100 --> 12:19.630 But all I'm going to do is go back to Fire Blast and just do what I was initially going to do copy the 12:19.630 --> 12:26.050 contents of Get description, paste them into git next level description and change the title here to 12:26.050 --> 12:27.580 Next Level. 12:28.370 --> 12:32.840 Like so and next time we compile, that change will be there. 12:32.870 --> 12:33.500 Okay. 12:33.500 --> 12:36.230 Great job and I'll see you in the next video.
