01:48.540 --> 01:50.190 So let's make one. 01:50.190 --> 01:53.490 I'm going to browse to where Fireblast exists. 01:53.490 --> 01:55.980 Create a new gameplay effect blueprint. 01:58.780 --> 02:03.760 And call this GE underscore cost fireblast. 02:04.180 --> 02:05.590 We're going to open it up. 02:05.590 --> 02:08.710 And the cost is going to be an instant effect. 02:08.710 --> 02:10.090 With one modifier. 02:10.090 --> 02:15.010 It's going to require mana just like our other spells. 02:15.100 --> 02:19.270 It's going to be add and the modifier magnitude will be negative one. 02:19.270 --> 02:22.000 But we're going to use a curve table. 02:22.980 --> 02:24.930 Spell cast and choose. 02:24.930 --> 02:26.460 Fire blast. 02:27.340 --> 02:35.680 We can compile, we can save, and we can take fireblast and set its cost gameplay effect to cost. 02:36.310 --> 02:37.480 Fireblast. 02:37.840 --> 02:42.400 Now when we activate the ability, we can commit ability cost. 02:45.030 --> 02:49.770 Like so, and we should be able to see that cost if we save all. 02:49.770 --> 02:52.080 If we press play, we level up. 02:55.830 --> 03:01.740 We purchase our spell, we equip it to two, and then I can hit number two. 03:02.100 --> 03:06.210 And we just did our cost commit there. 03:06.510 --> 03:06.900 Okay. 03:06.900 --> 03:10.680 So cost works I'm going to close CT spell cost. 03:10.710 --> 03:12.480 Now we need a cooldown. 03:12.480 --> 03:14.250 So I'm going to make a cooldown. 03:14.670 --> 03:15.750 Right click. 03:15.750 --> 03:17.580 We're going to add a gameplay effect. 03:18.470 --> 03:24.230 We're going to call this gameplay effect GE cooldown underscore fireblast. 03:25.610 --> 03:29.330 And this is going to be a duration based gameplay effect. 03:29.330 --> 03:31.190 So has duration. 03:31.190 --> 03:35.030 And I'm going to set the duration magnitude for this. 03:35.030 --> 03:39.620 And I think we can make the duration for this about five seconds. 03:39.620 --> 03:43.730 And we need a cooldown tag and the granted tags. 03:43.730 --> 03:45.740 So we're going to go to Project Settings. 03:45.740 --> 03:49.220 We're going to go to Gameplay Tags into cooldown. 03:49.220 --> 03:55.790 We're going to add a new cooldown tag and call this cooldown dot fire dot Fire Blast. 03:56.790 --> 04:01.890 And now we have a cooldown dot fire dot Fire Blast gameplay tag. 04:01.890 --> 04:07.950 We're going to go to Cooldown Fire Blast and add that to the granted tags so it's cooldown fire fire 04:07.950 --> 04:15.450 Blast, compile save, and we're going to get that into our Fire Blast gameplay ability. 04:15.450 --> 04:21.570 In Class Defaults, we're going to set the cooldown to Cooldown Fire Blast like so. 04:21.570 --> 04:30.330 And now if we end the ability, we should be able to activate it again, but not until our cooldown 04:30.330 --> 04:30.780 is over. 04:30.780 --> 04:37.080 As long as we commit the cooldown and we can commit cost and cooldown with commit ability. 04:39.110 --> 04:42.770 So I'm going to do that now instead of just the cost. 04:44.220 --> 04:53.460 Now before testing, I do want to go back into my data folder blueprints ability system data into ability 04:53.460 --> 04:58.650 info, because now that I have a cooldown tag, I can set it here Fire Blast. 04:58.650 --> 05:01.020 And with that I can press play. 05:01.020 --> 05:02.610 I can level up. 05:04.410 --> 05:11.880 And I can unlock Fireblast, and I can equip it to slot two, and I can press two. 05:12.300 --> 05:15.090 And there's my cooldown going down. 05:15.090 --> 05:17.850 And when it comes down, I can cast it again. 05:19.640 --> 05:21.020 And I can spam the key. 05:21.020 --> 05:24.530 I can't cast it until the cooldown is over. 05:25.040 --> 05:28.310 So with that, we have cast and cooldown. 05:28.310 --> 05:35.360 All that's left is to actually determine what happens when we cast Fireblast, and we'll do that next. 05:35.360 --> 05:37.430 So I'm going to close project settings. 05:37.430 --> 05:39.260 I'm done with my new effects. 05:39.260 --> 05:41.150 I'm going to keep Fireblast open. 05:41.150 --> 05:44.210 Save all and I'll see you soon.
