WEBVTT 00:07.600 --> 00:12.550 All right, so now that we have some damage parameters, it's time to start using them. 00:12.550 --> 00:13.900 So how do we use them. 00:14.290 --> 00:18.670 Well for one we have an aura ability system library function. 00:18.670 --> 00:27.520 If we go into Aura ability system library and search for our apply damage effect, we have one here 00:27.520 --> 00:29.440 that takes in damage effect params. 00:29.440 --> 00:38.800 So in a way, most of the work that has to be done in gas is being done for us by these worker functions 00:38.800 --> 00:44.530 that just set things right, and it's setting all of our set by color magnitudes, and it's setting 00:44.530 --> 00:49.090 our death impulse and knockback force on the effect context. 00:49.090 --> 00:55.030 And as soon as we call apply damage effect, we can pass those parameters in for radial damage. 00:55.030 --> 01:01.900 And then later on down the pipeline, we can see about calculating how much damage was actually done 01:02.110 --> 01:04.270 for those given parameters. 01:04.270 --> 01:04.930 Right. 01:04.930 --> 01:10.630 So right here when we're setting our death impulse and our knockback force, I think it would be a great 01:10.630 --> 01:16.150 idea to set those radial damage parameters on our effect context as well. 01:16.150 --> 01:24.160 And it'd be handy if we had these setters, these functions that do all of the dirty work for us, so 01:24.160 --> 01:24.910 to speak. 01:24.910 --> 01:31.630 So let's make those setter functions and getter functions here in Aura Ability System library that we 01:31.630 --> 01:36.160 can use now scrolling I just see kind of a wall of text. 01:36.160 --> 01:40.150 I'd like to categorize these into categories. 01:40.150 --> 01:47.710 At this point I'd like to say something like widget controller right here. 01:47.710 --> 01:50.140 And then underneath that. 01:52.960 --> 01:56.920 We'll say ability system startup. 01:59.080 --> 02:03.880 Right or even just ability system class defaults. 02:05.200 --> 02:11.170 And then we have these functions for our gameplay effect context. 02:11.170 --> 02:11.830 Right. 02:11.830 --> 02:15.820 Gameplay effects like is blocked hit is successful debuff. 02:15.820 --> 02:20.560 So I'm going to have effect context getters. 02:21.320 --> 02:23.300 Because these are all getters. 02:24.040 --> 02:26.290 And then we have the setters as well. 02:27.510 --> 02:31.470 So this will be effect context setters. 02:31.980 --> 02:32.340 There. 02:32.340 --> 02:33.810 Now we can see where things are. 02:33.840 --> 02:36.300 Now the setters end right here. 02:36.870 --> 02:38.040 No they don't. 02:38.040 --> 02:40.800 They end down here. 02:44.050 --> 02:50.380 And then we have things like get live players within radius, get closest targets is not friend, right? 02:50.380 --> 02:52.510 These are for gameplay mechanics. 02:54.740 --> 02:57.500 So those are our gameplay mechanics algorithms. 02:57.500 --> 03:03.410 And then of course apply damage effect is I'll consider that some gameplay mechanics. 03:03.410 --> 03:09.020 It's related to gameplay effects, but it's actually applying an effect. 03:09.020 --> 03:12.680 So I'd say all of these can be in gameplay mechanics. 03:12.680 --> 03:18.680 So now that we have an easy way to find where all the setters and getters are, we can add our getters 03:18.680 --> 03:19.220 right here. 03:19.220 --> 03:22.190 I'm going to go ahead and make these static functions. 03:22.580 --> 03:27.530 So first static bool is radial damage. 03:28.040 --> 03:36.320 It's going to get the effect context handle and we'll give it blueprint pure gameplay effects. 03:36.320 --> 03:43.910 We're also going to make a static float returning function get radial damage inner radius. 03:49.000 --> 03:51.940 And all the getters are going to get these. 03:53.040 --> 03:56.100 Const refs to affect context handle. 03:56.460 --> 04:03.300 Now I'm going to just copy this one because the next one is going to be the radial damage outer radius. 04:05.670 --> 04:09.030 And finally a f vector returning function. 04:09.030 --> 04:11.610 So static f vector. 04:12.600 --> 04:15.990 Get radial damage origin. 04:21.860 --> 04:23.840 With the same you function. 04:26.130 --> 04:27.300 All right. 04:30.620 --> 04:33.140 So we can implement these functions. 04:38.100 --> 04:45.090 And I'm going to steal some code from is critical hit, because it's going to be nearly the same. 04:45.090 --> 04:47.460 We're just going to call is radial damage. 04:48.650 --> 04:51.800 And I'm going to steal one that returns a float. 04:54.380 --> 04:56.570 I'll take git debuff frequency. 04:58.340 --> 05:04.820 And we'll just call get radial damage in a radius for this one. 05:06.000 --> 05:07.410 And get radial damage. 05:07.410 --> 05:09.300 Outer radius for this one. 05:13.830 --> 05:16.260 And then we have get radial damage origin. 05:16.260 --> 05:19.920 I'm just going to steal the contents of one that returns a vector. 05:21.610 --> 05:26.560 And paste it in and call git radial damage origin. 05:26.560 --> 05:28.030 So we have our getters. 05:28.480 --> 05:33.610 Now for the setters I'm going to copy set is successful debuff. 05:36.010 --> 05:43.450 Just because it takes in a boolean and this will be set is radial damage. 05:46.870 --> 05:51.220 Its input will be called B in is radial damage. 05:52.560 --> 05:55.290 I'm also going to copy one that takes in a float. 06:00.790 --> 06:02.560 And this one can be called. 06:03.930 --> 06:06.180 Set radial damage. 06:06.180 --> 06:12.750 Inner radius with a float called in inner radius. 06:13.230 --> 06:14.400 I'll just make it easy. 06:14.430 --> 06:18.120 We'll also have the outer radius version. 06:18.540 --> 06:23.970 Set radial damage outer radius and it'll have an outer radius. 06:25.350 --> 06:28.890 And let's get a function that takes in a vector. 06:29.980 --> 06:31.060 Here's one. 06:35.230 --> 06:37.120 And this will be set. 06:37.810 --> 06:39.790 Radial damage. 06:39.790 --> 06:40.750 Origin. 06:42.890 --> 06:45.530 And it'll take in in origin. 06:47.110 --> 06:48.370 And with that. 06:49.080 --> 06:51.120 We can define these functions. 06:56.950 --> 06:59.320 Now it's given me inline functions. 06:59.320 --> 07:01.900 Unfortunately I'm going to control X. 07:01.900 --> 07:04.360 Cut those and we'll paste them here. 07:05.850 --> 07:08.490 And we'll just get them right here. 07:08.490 --> 07:10.890 I'm going to remove the inline keyword. 07:14.100 --> 07:17.880 And let's find a setter that takes in a bool. 07:21.780 --> 07:23.040 Set is successful. 07:23.040 --> 07:24.150 Debuff will do. 07:29.780 --> 07:31.820 And we'll call. 07:32.810 --> 07:41.330 In this function set is radial damage and pass in B in is radial damage. 07:41.930 --> 07:45.080 Let's find one of our setters that takes in a float. 07:45.860 --> 07:46.970 Here's one. 07:50.860 --> 07:52.450 And we'll use that here. 07:53.560 --> 07:57.550 We're going to call set radial damage. 07:57.550 --> 08:01.600 Inner radius passing in in inner radius. 08:03.270 --> 08:04.800 And we'll copy this. 08:05.070 --> 08:08.640 Paste it in the set radial damage outer radius. 08:08.670 --> 08:14.610 We'll call the outer version passing in an outer radius. 08:15.240 --> 08:18.360 And let's find a function that takes in a vector. 08:18.360 --> 08:19.350 This one will do. 08:19.350 --> 08:24.030 Set death impulse and we'll paste its contents here. 08:24.030 --> 08:32.760 And instead of set death impulse we're going to call set radial damage origin passing in the in origin 08:32.760 --> 08:33.690 okay. 08:34.020 --> 08:37.770 So for getters for setters we're all set. 08:37.770 --> 08:42.120 Now we can go back down to our apply damage effect. 08:42.120 --> 08:47.670 And just after setting death impulse and knockback force we can set the four parameters on our effect. 08:47.670 --> 08:50.940 Context we're going to set is radial damage. 08:51.680 --> 08:58.640 So first we pass in the effect context handle and then we get our damage effect params dot b is radial 08:58.640 --> 08:59.420 damage. 09:01.060 --> 09:05.530 Next we can set radial damage inner radius. 09:05.530 --> 09:10.900 And really, it doesn't matter if B is radial damage is false. 09:10.900 --> 09:16.540 We could place all this in an if check, but it doesn't matter if we set it anyway because the context 09:16.540 --> 09:19.600 isn't going to serialize it if this boolean is false. 09:19.600 --> 09:26.350 So we'll just go ahead and set them and keep our code cleaner without an if statement here. 09:27.100 --> 09:33.220 And we'll set this to radial damage inner radius on the damage effect params. 09:33.220 --> 09:43.180 Let's also set radial damage outer radius passing in the context handle getting our damage effect params 09:43.180 --> 09:47.650 radial damage, outer radius and the origin. 09:47.650 --> 09:49.930 So set radial damage origin. 09:50.650 --> 09:56.470 First we got the handle, then the damage params dot radial damage origin. 09:57.070 --> 09:59.230 And we've set those four parameters. 09:59.230 --> 10:06.910 Now we can pass those along through the pipeline and access them anywhere, such as in our exact calc 10:06.910 --> 10:08.830 damage for example. 10:08.830 --> 10:15.700 So now that that is complete, we can then move on to using these in the context handle and we'll do 10:15.700 --> 10:16.840 that next. 10:16.840 --> 10:17.800 I'll see you soon.
