WEBVTT 00:06.830 --> 00:08.040 Welcome back. 00:08.060 --> 00:15.830 So we're initializing health and mana with hardcoded values, and that's definitely not something that 00:15.830 --> 00:17.150 we like to do, is it? 00:17.150 --> 00:19.760 So we're not going to do it that way. 00:19.790 --> 00:25.480 We're not going to call init health and init mana here in the constructor anymore. 00:25.490 --> 00:27.680 I'm removing those now. 00:27.680 --> 00:30.140 What do we want to initialize health and mana to? 00:30.140 --> 00:36.260 Well, our max health and max mana are dependent on other attributes. 00:36.290 --> 00:38.120 Max health is dependent on vigor. 00:38.120 --> 00:40.070 It's also dependent on player level. 00:40.280 --> 00:47.930 Max Mana is dependent on intelligence and player level, so it's kind of hard to tell what that's going 00:47.930 --> 00:52.310 to be if we want to hard code it in, but we don't want to hard code it in. 00:52.340 --> 01:00.500 We want to set health and mana to the max values and we have to do that after max health and Max Mana 01:00.500 --> 01:01.990 have been set. 01:02.000 --> 01:04.970 So timing is important here. 01:04.970 --> 01:12.780 And again, what's our preferred or at least my preferred way to set attribute values that's well by 01:12.780 --> 01:14.040 gameplay effects. 01:14.040 --> 01:21.870 So I would like to have gameplay effects that initialize health and mana and initialize them to the 01:21.870 --> 01:24.090 values of max health and max mana. 01:24.120 --> 01:29.520 That's what I'd like them to be set to and this doesn't need to be an infinite gameplay effect. 01:29.520 --> 01:34.140 It could be an instant one that just sets health and mana just initializes them. 01:34.140 --> 01:35.490 So that's what I'd like. 01:35.880 --> 01:38.910 And this is going to be your quest. 01:39.610 --> 01:43.360 So you're going to initialize your vital attributes. 01:43.360 --> 01:48.070 And I'd like you to do this by creating a gameplay effect to do so. 01:48.190 --> 01:51.670 So for now, our vital attributes are health and max health. 01:51.670 --> 01:58.890 So set health equal to the value of max health and set your mana equal to the value of max mana. 01:58.900 --> 02:01.510 And after that of course you can play test. 02:01.540 --> 02:08.440 This will ensure that our health, globe and mana globe are initialized to full right and you have to 02:08.440 --> 02:14.770 do this after max Health and Max Mana have already been initialized or at least set for the first time. 02:14.770 --> 02:19.570 So make sure that you figure out the right timing and everything else. 02:19.570 --> 02:22.240 You have all the skills that you need to do this. 02:22.240 --> 02:27.760 So pause the video, conquer this quest and initialize your vital attributes now. 02:31.080 --> 02:31.560 Okay. 02:31.560 --> 02:37.560 So if we're going to have a gameplay effect to initialize our vital attributes, I think that should 02:37.560 --> 02:44.400 be a variable and I'd like to set that where we have our other variables for the gameplay effects that 02:44.400 --> 02:46.320 initialize our attributes. 02:46.320 --> 02:52.770 And that's going to be on our Aura character base class right here. 02:52.770 --> 02:59.640 We have default primary attributes, default secondary attributes, and I'd like to set our default 02:59.640 --> 03:01.290 vital attributes. 03:01.290 --> 03:07.350 So we're going to have whoops, we're going to have a gameplay effect class for that and this will be 03:07.380 --> 03:09.990 default vital attributes. 03:09.990 --> 03:12.270 And how are we going to apply it? 03:12.270 --> 03:15.090 Well, we have our nice apply effect to self. 03:15.090 --> 03:25.230 We can call that if I control over into the CPP file, I see that first we're applying the default primary 03:25.230 --> 03:32.560 attributes, then the default secondary, and after that we can do the vital because our secondary attributes 03:32.560 --> 03:39.730 have to be set before the vital because the secondary attributes include max health and max mana. 03:39.730 --> 03:46.930 So after this function call, the secondary attributes will be initialized and now we can initialize 03:46.930 --> 03:51.250 vital equal to the values of those secondary attributes. 03:51.250 --> 03:59.890 So we're going to call apply effect to self passing in default vital attributes and we'll pass in a 03:59.890 --> 04:02.350 level of one and that's it. 04:02.350 --> 04:07.420 Now we just need to create our default vital attributes gameplay effect. 04:07.420 --> 04:08.950 So let's go ahead and run. 04:08.950 --> 04:15.910 I'll go ahead and run in debug mode and then we'll create that and hopefully we should see our health 04:15.910 --> 04:18.550 and Mana Globes start off full. 04:19.410 --> 04:19.950 Okay. 04:19.950 --> 04:28.260 So what we can do is we can go into our blueprints, ability system, gameplay effects, default attributes, 04:28.260 --> 04:34.230 and we can create our default vital attributes gameplay effect. 04:34.230 --> 04:40.890 So I'm going to make a new blueprint class choosing gameplay effect as the parent class and we'll call 04:40.890 --> 04:45.780 this G underscore aura vital attributes. 04:45.900 --> 04:51.090 Let's open this up and we want this to be an instant gameplay effect. 04:51.090 --> 04:56.850 I'll leave that at instant and we'll add a modifier to set the value of health. 04:56.850 --> 04:58.350 We're going to initialize it. 04:58.350 --> 05:00.960 So the attribute is going to be health. 05:00.960 --> 05:03.810 The modifier OP will be override. 05:03.840 --> 05:11.310 The magnitude is going to be attribute based because we want to set it equal to the attribute of our 05:11.310 --> 05:11.910 max health. 05:11.910 --> 05:15.120 So the attribute to capture will be max health. 05:15.120 --> 05:19.870 The attribute source will be target and that's all we need for health. 05:19.870 --> 05:22.570 We're going to do the same thing for Mana. 05:22.570 --> 05:26.350 So I'm going to collapse that index and add another modifier. 05:26.620 --> 05:29.170 This modifier is attribute will be mana. 05:29.200 --> 05:36.580 The modifier op will be override modifier magnitude calculation type is going to be attribute based. 05:36.610 --> 05:41.770 We'll expand this and our backing attribute is going to be Max Mana. 05:41.770 --> 05:44.950 It's going to be from the target and that's it. 05:44.980 --> 05:52.450 Now as soon as we start the game, we should have this gameplay effect applied as long as we set it 05:52.480 --> 05:53.320 on aura. 05:53.320 --> 06:01.840 So we need to go back to blueprints, character, aura, BP Aura, character, and we need to set that. 06:01.840 --> 06:05.710 It's right here under attributes our default vital attributes. 06:05.710 --> 06:08.230 If we didn't set this, we're doing a check there. 06:08.230 --> 06:11.770 So we are asserting that we have this set. 06:11.770 --> 06:15.160 So let's set it G or a vital attributes. 06:15.160 --> 06:16.210 Now it's set. 06:16.240 --> 06:17.890 We can save all. 06:18.450 --> 06:21.420 And we can press play and look at that. 06:21.420 --> 06:26.850 We have two nice big, beautiful full globes of health and mana. 06:26.850 --> 06:35.070 And if we go ahead and show debug, well, I don't really see health or mana anymore, so show debug 06:35.070 --> 06:39.720 is a little bit less useful these days, but we're good. 06:39.720 --> 06:40.620 I trust it. 06:40.620 --> 06:47.790 I think that my health and my mana are correct and we're going to verify that very soon by actually 06:47.790 --> 06:54.480 showing things like the numerical values of our attributes in our UI elements. 06:54.480 --> 06:56.490 So we'll be doing those things next. 06:56.490 --> 06:59.850 But for now, great job and this is a good milestone. 06:59.850 --> 07:02.250 You've learned a lot about gameplay effects. 07:02.250 --> 07:11.280 We've learned a whole lot about the different modifiers and there are different types of magnitude calculation 07:11.280 --> 07:11.640 types. 07:11.640 --> 07:14.940 We learned about scalable float and attribute based. 07:14.970 --> 07:17.370 We know about custom calculation class. 07:17.370 --> 07:20.740 We don't know about that fourth one there set by caller. 07:20.740 --> 07:23.860 So that's the one that we still need to learn. 07:23.860 --> 07:26.200 We'll get to that in this course. 07:26.200 --> 07:27.880 Don't worry, we're covering them all. 07:27.910 --> 07:34.090 But it was a lot to learn just these three and you're a lot more powerful just knowing those three. 07:34.090 --> 07:39.220 So it's just a testament to how useful and powerful gas is. 07:39.220 --> 07:45.720 So congratulations on all we've learned so far, and it only gets better from here. 07:45.730 --> 07:47.440 I'll see you in the next video.
