WEBVTT 00:07.000 --> 00:07.570 Okay. 00:07.570 --> 00:15.100 So now that we have an on overlap and an on end overlap function, we can decide whether or not to apply 00:15.100 --> 00:19.930 our various gameplay effects based on their application policy, right? 00:19.930 --> 00:23.380 So for the instant effect, we'll start with that one. 00:23.380 --> 00:30.070 It has its instant effect application policy and if it's set to do not apply well, we don't need to 00:30.070 --> 00:30.910 do anything. 00:30.910 --> 00:37.330 But if it's set to apply on overlap, we need to apply that effect in our on overlap function. 00:37.330 --> 00:41.410 And if it's set to apply on end overlap, we'll apply it then. 00:41.500 --> 00:46.600 So let's check this application policy in our on overlap function first. 00:46.690 --> 00:58.660 So here in on overlap, let's say if instant effect application policy is equal to e effect application 00:58.660 --> 01:05.440 policy, apply on overlap, then we can apply the instant effect to the target. 01:05.440 --> 01:07.640 So we have apply effect to target. 01:07.670 --> 01:16.460 We can call that we can call apply effect to target passing in the target actor and for the effect we 01:16.460 --> 01:20.450 can use the instant gameplay effect class. 01:20.450 --> 01:26.210 And if we set this to apply on overlap, we'd better be sure that our gameplay effect class is set. 01:26.240 --> 01:29.000 Otherwise we'll get a crash thanks to that check. 01:29.000 --> 01:32.390 So that's just something that we need to keep in mind. 01:32.690 --> 01:39.800 We can't set this to an incompatible enum constant if we don't have an instant effect to apply. 01:39.830 --> 01:45.740 Now, what if our instant effect has its policies set to apply on end overlap? 01:45.740 --> 01:50.180 Well, then we do it here so we can place a check and end overlap. 01:50.180 --> 02:00.860 If instant effect application policy equals e effect, application policy apply on end overlap, then 02:00.860 --> 02:09.140 we can call apply effect to target passing in the instant gameplay effect class so that takes care of 02:09.140 --> 02:11.120 applying our instant effect. 02:11.120 --> 02:14.330 And that's the most simple case. 02:14.330 --> 02:22.040 Now the next effect duration policy would be duration effect because a duration effect removes itself. 02:22.040 --> 02:26.060 We don't have to check its removal policy or anything like that. 02:26.090 --> 02:34.160 We just need to check its application policy and we can simply apply the effect here in on overlap or 02:34.160 --> 02:36.260 end overlap based on its policy. 02:36.260 --> 02:39.080 So we can check that just like we did for the instant effect. 02:39.080 --> 02:47.660 We're going to say if duration effect application policy equals and we'll check if it's apply on overlap. 02:48.080 --> 02:57.980 And if it is, we'll call apply effect to target passing in target actor and this time the duration 02:57.980 --> 02:59.480 gameplay effect class. 02:59.870 --> 03:08.180 We'll do the same exact thing and end overlap if the effect application policy this time is apply on 03:08.180 --> 03:09.260 end overlap. 03:09.260 --> 03:13.430 So that case is just about as simple as the instant effect. 03:13.460 --> 03:16.070 We apply it and it removes itself. 03:16.070 --> 03:26.090 Now the more complicated case is the infinite effect because the infinite effect can be removed and 03:26.090 --> 03:33.170 we want to remove the infinite effect on end overlap if we've given it to the actor in question. 03:33.170 --> 03:35.600 So how do we remove the effect? 03:35.660 --> 03:40.790 How do we know on end overlap that that actor has the effect? 03:40.880 --> 03:43.700 How do we check that and how do we remove it? 03:43.850 --> 03:47.780 Well, let's go back to our code for apply effect to target. 03:47.810 --> 03:49.790 How are we applying the effect? 03:49.820 --> 03:52.850 We're first making an effect context. 03:52.880 --> 03:59.480 We're using the effect context handle and the gameplay effect class to make an outgoing spec that gives 03:59.480 --> 04:00.770 us a spec handle. 04:00.770 --> 04:06.710 Then we apply that gameplay effect spec getting the spec from the handle dereferencing the pointer and 04:06.710 --> 04:07.880 passing that in. 04:07.880 --> 04:14.450 So the question arises how do we remove the effect once we've already added it and we'll handle that 04:14.450 --> 04:15.950 in the next video?
