WEBVTT 00:06.810 --> 00:07.980 Welcome back. 00:08.130 --> 00:13.680 Now, when we press play and we look at our spells, we can see that we have one spell equipped. 00:13.710 --> 00:20.460 Now, one of the things that I want to do is when I level up, I want to see what other spells I'm eligible 00:20.490 --> 00:22.790 to spend points on. 00:22.800 --> 00:28.920 And so that means as soon as I do level up, as in like I'm doing here. 00:29.810 --> 00:37.910 I should be able to open my spells menu and any abilities that have that level requirement equal to 00:37.910 --> 00:41.640 the level that I've just reached should now show as eligible. 00:41.660 --> 00:44.190 We shouldn't see a locked icon for those. 00:44.210 --> 00:48.110 We should see what the icon for that ability is supposed to be. 00:48.140 --> 00:54.050 Now, for that reason, we need the concept of a level requirement for our spells, and I'd like to 00:54.050 --> 00:56.180 keep that in my data asset. 00:57.190 --> 01:05.260 So in content blueprint's ability system data, I have my ability info data asset and I'd like to be 01:05.290 --> 01:08.830 able to set the level requirement for a given ability here. 01:08.860 --> 01:15.550 That way, every time we level up we can check the level requirements for these abilities and grant 01:15.550 --> 01:17.830 those abilities to the player. 01:17.830 --> 01:20.980 If that player now meets those level requirements. 01:21.010 --> 01:25.390 Now, Aura isn't going to have all of her abilities right away. 01:25.420 --> 01:29.220 She only starts with those abilities in her start up abilities array. 01:29.230 --> 01:36.190 So as we add more abilities that she will not start with our ability system component needs to know 01:36.190 --> 01:38.410 what class of ability to grant. 01:38.410 --> 01:45.670 So ability information should also contain a class that the ability system component can retrieve and 01:45.670 --> 01:49.570 then give that ability to aura and set its ability status. 01:49.900 --> 01:57.190 So we're going to add two things to our ability info struct, a gameplay ability class and a level requirement 01:57.290 --> 02:01.010 set and both will be exposed to our data asset. 02:01.010 --> 02:02.840 So let's close the editor. 02:04.700 --> 02:14.090 We'll close all tabs and let's go into our public folder into ability system data and ability info. 02:14.850 --> 02:19.800 Our ability info struct is going to now have a level requirement. 02:19.950 --> 02:21.750 So we're going to add that. 02:22.860 --> 02:26.310 It'll be an int 32, we'll call it level requirement. 02:27.000 --> 02:30.780 It's going to be edit defaults only blueprint read only. 02:30.780 --> 02:33.480 So we'll go ahead and give it that new property. 02:34.560 --> 02:41.490 In addition to that, we need a subclass of this will be for the game play ability, which means we're 02:41.490 --> 02:48.690 going to need to forward declare that class class you gameplay ability. 02:49.590 --> 02:58.620 So let's add this subclass of t subclass of you gameplay ability and this is going to be the ability 02:58.620 --> 02:59.430 itself. 02:59.430 --> 03:05.370 We can just call it ability and this too will get added defaults only and we'll make it blueprint read 03:05.370 --> 03:06.000 only. 03:06.300 --> 03:14.100 So now that we have this level requirement and the gameplay ability class itself, our ability system 03:14.100 --> 03:21.320 component is going to need to know when we level up and when it does, it needs to access ability info. 03:21.330 --> 03:27.330 So we need a nice central place where we can put one of these ability infos that our ability system 03:27.330 --> 03:29.340 component can get it from. 03:29.340 --> 03:35.200 And I'd like to add that to the game mode as that's a nice central place that only exists on the server. 03:35.380 --> 03:42.700 So let's go into the game folder to or a game mode base and we'll add a new object pointer here. 03:42.700 --> 03:48.130 It's going to be T object pointer of type you ability info. 03:48.940 --> 03:54.730 We're going to go ahead and forward declare it and call this ability info. 03:54.850 --> 04:01.420 We'll make it edit defaults only and the category can be just ability info. 04:02.790 --> 04:04.810 Now it exists on the game mode. 04:04.830 --> 04:07.650 I'd like it to be easily obtainable. 04:07.650 --> 04:11.850 I'd like a nice function that can get it in our ability system library. 04:11.850 --> 04:14.760 So let's go to our ability system library. 04:14.910 --> 04:18.570 Now we have already one function that returns a data asset. 04:18.570 --> 04:20.850 It's called get character class info. 04:20.880 --> 04:26.580 We're going to model this new function after this one, so I'm going to copy and paste it and call this 04:26.580 --> 04:28.650 one get ability info. 04:29.630 --> 04:33.260 Its type that it returns will be you ability info. 04:34.820 --> 04:36.860 We'll go ahead and forward declare it. 04:36.900 --> 04:39.200 It'll take a world context object. 04:39.230 --> 04:45.020 Let's go ahead and generate the definition and it's going to be similar to get character class info. 04:45.050 --> 04:50.750 I'm going to copy the contents of that function and paste it here because we do want our A game mode 04:50.750 --> 04:51.470 base. 04:51.500 --> 04:54.800 We're going to get that and check to see if it's Null first. 04:54.800 --> 05:01.610 And if it's not null, we'll get our aura game mode and return the ability info on it. 05:02.250 --> 05:04.980 Now both of these can be made const. 05:05.590 --> 05:11.170 So while I'm at it here, I'll go ahead and make them both const and now we have Git ability info, 05:11.200 --> 05:13.690 which is a very easy to use function. 05:13.690 --> 05:18.310 It exists on our ability system library and we can use that. 05:18.340 --> 05:25.420 Now we can go ahead and just compile and launch the editor and set the level requirement for the one 05:25.450 --> 05:31.120 ability we have in our data asset as well as set the ability info on the game mode. 05:32.190 --> 05:35.670 Okay, I'm going to click open and get that ability info back up. 05:35.670 --> 05:42.600 Now, level requirement is going to have a value of one for our firebolt, which doesn't really matter 05:42.600 --> 05:47.400 because it's one of the startup abilities, but now it's level requirement is set. 05:47.610 --> 05:50.610 And by the way, that's zero because we're not setting it. 05:51.060 --> 05:53.100 We'll get an error if we don't. 05:53.100 --> 05:57.450 So I'm going to set that to a default value of one in C plus plus. 05:58.520 --> 06:00.360 So that's one thing that we need to do. 06:00.380 --> 06:01.550 I'm going to save that. 06:01.550 --> 06:08.090 And the next thing is to go into our blueprints game folder, open our blueprint for the game mode and 06:08.090 --> 06:10.520 set its ability info data asset. 06:10.550 --> 06:15.080 Now we can always access it at least on the server where the game mode exists. 06:15.820 --> 06:18.100 Okay, so we're almost done. 06:18.100 --> 06:24.640 But now that we have a level requirement, we're going to want to check it every time we level up and 06:24.640 --> 06:26.800 then change the icons here. 06:26.800 --> 06:29.590 But to do that, we need other abilities. 06:29.590 --> 06:31.600 We need at least one more ability. 06:31.630 --> 06:34.780 Now, this middle column is going to be for lightning abilities. 06:34.780 --> 06:42.250 So I think I'm going to create a placeholder ability that can go right here for our next ability that 06:42.250 --> 06:43.390 I'd like to show. 06:43.420 --> 06:50.140 Once we become eligible, I'd like to show the eligible icon for it in the next column. 06:50.440 --> 06:53.680 So let's go ahead and make a new gameplay ability. 06:53.680 --> 07:00.910 I'm going to go to Blueprints, Ability System, Aura abilities and make a new folder here called Lightning 07:01.150 --> 07:03.610 and we'll make our first lightning ability. 07:03.610 --> 07:09.100 Let's right click, make a new blueprint and we're going to base this on Aura gameplay ability. 07:11.750 --> 07:18.050 And we'll call this G a underscore and let's choose a cool name for it. 07:18.530 --> 07:19.940 Electrocute. 07:21.660 --> 07:25.730 Electrocute is going to be just a basic gameplay ability. 07:25.740 --> 07:36.510 In fact, we can just print a string for now that says electrocute activated and we can simply use a 07:36.510 --> 07:37.470 delay. 07:39.260 --> 07:42.980 For one second and in the ability. 07:45.590 --> 07:48.170 We'll definitely be making this a real ability. 07:48.200 --> 07:50.000 For now, it's just a placeholder. 07:50.390 --> 07:53.990 But now we actually have a gameplay ability. 07:54.020 --> 07:55.820 Aside from Firebolt. 07:56.520 --> 08:03.750 Now in class defaults, we're going to need a gameplay tag to identify this ability as we only have 08:03.750 --> 08:04.560 abilities. 08:04.560 --> 08:07.860 Fire firebolt and of course attack. 08:07.890 --> 08:14.460 I'm going to want abilities lightning electrocute to add to that and then we can add it to our data 08:14.460 --> 08:14.910 asset. 08:14.910 --> 08:21.180 So let's go ahead and close the editor and add a new gameplay tag in or a gameplay tags. 08:21.180 --> 08:22.950 Let's find our abilities. 08:23.100 --> 08:24.270 Here they are. 08:24.300 --> 08:26.250 Here's my fire Firebolt. 08:26.700 --> 08:34.830 I'm just going to copy and paste it and change this one to abilities Lightning underscore electrocute. 08:35.550 --> 08:38.790 So we'll go ahead and define this gameplay tag. 08:39.670 --> 08:41.830 I'm going to find Firebolts. 08:42.220 --> 08:44.050 That's the cooldown tag. 08:44.670 --> 08:46.320 Here's the ability tag. 08:47.290 --> 08:48.580 I'll copy this one. 08:48.580 --> 08:51.550 And just beneath it we'll paste it. 08:51.550 --> 08:58.090 But this will be abilities lightning electrocute so its tag will be abilities. 08:58.090 --> 09:01.930 Dot lightning dot electrocute. 09:03.630 --> 09:08.530 And the comment will say electrocute ability tag. 09:08.550 --> 09:12.540 Now that we have this tag, we'll compile and go back to the editor. 09:14.220 --> 09:20.280 Okay, so let's go ahead and get everything open again for Electrocutes ability tags. 09:20.280 --> 09:26.040 We're going to add a tag Abilities Lightning Electrocute. 09:26.660 --> 09:35.990 So just like our other ability abilities, fire Firebolt and the Firebolt ability tags contains abilities. 09:36.230 --> 09:37.880 Fire Firebolt. 09:37.910 --> 09:40.700 That's what we use to identify that ability. 09:40.730 --> 09:44.150 Now electrocute is identified with abilities. 09:44.150 --> 09:45.620 Lightning electrocute. 09:46.430 --> 09:47.900 Let's go ahead and save that. 09:47.900 --> 09:53.780 And now here in ability info, we can set up our new ability electrocute. 09:53.780 --> 09:58.820 By the way, aside from level requirement, we also have the ability itself. 09:58.820 --> 10:04.190 Again, Firebolt is one of the start up abilities, so it doesn't matter much, but we can set that 10:04.190 --> 10:06.770 gameplay ability to firebolt there. 10:06.770 --> 10:10.910 And now let's add a new element to ability information. 10:10.910 --> 10:14.810 This will be the next element and we can set its ability tag. 10:14.810 --> 10:18.800 It's going to be abilities, lightning electrocute. 10:18.800 --> 10:27.590 It doesn't have a cooldown tag yet, but we can set its icon now if we search for shock and choose that 10:27.620 --> 10:33.140 we have this texture and if you open it, you'll see that it looks like a lightning bolt. 10:33.590 --> 10:34.940 We're going to use that. 10:34.940 --> 10:40.460 And for the background material, let's actually see what other flowing materials we have by browsing 10:40.490 --> 10:41.330 to fire skill. 10:41.360 --> 10:44.720 BG Here we have an my shock skill. 10:44.750 --> 10:48.300 BG I'm going to select it and choose that one. 10:48.720 --> 10:54.570 And for the level requirement for electrocute, I'm going to set it to two and for the ability I'm going 10:54.570 --> 10:57.270 to set it to a electrocute. 10:57.890 --> 11:03.110 And now our ability info has info for this ability. 11:03.410 --> 11:11.600 Now that means we can go to our offensive spell tree in blueprints ui spell menu. 11:11.630 --> 11:19.340 Offensive spell tree and assign our new electrocute tag to one of these spell globes and it's going 11:19.340 --> 11:23.240 to go into the bottom most globe in the second column. 11:23.240 --> 11:29.360 So here I'm going to search for its ability tag and set that ability tag to lightning electrocute. 11:30.000 --> 11:33.660 So now that one has the electrocute tag. 11:34.390 --> 11:42.100 Okay, so now our abilities have the concept of a level requirement, and every time we level up, we're 11:42.100 --> 11:47.260 going to expect our offensive spell tree to update itself. 11:47.260 --> 11:53.020 And as soon as we meet the level requirements for any of those other abilities in our ability info, 11:53.050 --> 11:59.350 I want to be able to first of all give that ability to aura and then set its status so that we can see 11:59.350 --> 12:01.390 what the icon is supposed to look like. 12:01.390 --> 12:07.480 So we have a few more steps to go, but we're making good progress and we'll continue with this in the 12:07.480 --> 12:08.590 next video. 12:08.620 --> 12:09.790 I'll see you soon.
