WEBVTT 00:06.850 --> 00:08.140 Welcome back. 00:08.290 --> 00:15.460 Now that we have rich text blocks and we have the capability of setting their styles by formatting the 00:15.460 --> 00:22.120 text used by the rich text block, we can now implement spell descriptions, and I'd like this to be 00:22.120 --> 00:24.700 a quality of the spell class itself. 00:25.300 --> 00:33.370 So what I'm going to do is close out of the editor and I'm going to close all my tabs and go into my 00:33.370 --> 00:35.290 aura gameplay ability. 00:36.000 --> 00:37.470 So in abilities. 00:38.500 --> 00:46.420 We have ora gameplay ability and for each of our ora gameplay abilities I'd like to have a virtual function 00:46.450 --> 00:54.550 that child abilities can override and these are going to return the spell description so they'll be 00:54.550 --> 00:57.100 public, they're going to be virtual. 00:57.100 --> 01:01.720 We plan on overriding them and they'll return an F string. 01:01.900 --> 01:08.170 F strings are just easy to manipulate and we'll call this one get description. 01:09.200 --> 01:13.700 And description will depend on the level, so we'll pass that in as an int 32. 01:13.730 --> 01:17.150 So our description will change based on that level. 01:17.330 --> 01:23.720 Now we also need a string returning function for the next level, so we're going to make a virtual F 01:23.720 --> 01:29.420 string returning function called Get Next Level description. 01:31.260 --> 01:36.270 And this will also take in an int 32 called level. 01:38.580 --> 01:41.040 So we can generate definitions. 01:43.450 --> 01:50.500 And the aura gameplay ability implementation of this is just going to return some default text. 01:50.500 --> 01:55.180 So we'll just say return F string print f. 01:56.390 --> 02:01.100 Text and we'll go ahead and format it with one of our rich text styles. 02:01.100 --> 02:07.520 So I'm going to use default here and what I can do inside of this. 02:09.230 --> 02:15.140 As I can say, percent s with a comma there and a space. 02:15.350 --> 02:20.960 And then after using the default style, I can use the level style. 02:25.060 --> 02:26.860 And percent here. 02:28.210 --> 02:32.910 So this is a print F So what I can do is use string literals here. 02:32.920 --> 02:39.520 If I use an uppercase L with quotes, that's going to make a wide character for me and I can just say 02:39.550 --> 02:46.420 default ability name and just put a whole bunch of text when we want a whole bunch of text and it doesn't 02:46.420 --> 02:49.180 matter what it says, we say Lorem ipsum. 02:50.650 --> 02:56.770 Many times over, so I'm just going to go ahead and paste Lorem ipsum a bunch of times. 02:59.020 --> 03:05.290 And after that, since we also have a percent de I can also put my level in there. 03:05.320 --> 03:06.250 Why not? 03:07.480 --> 03:09.930 So we're just giving some default text here. 03:09.960 --> 03:11.530 Doesn't matter what it says. 03:11.530 --> 03:18.610 And for the next level description, we'll say return F string print f. 03:20.920 --> 03:25.510 Text and we'll just put we'll use the default. 03:27.760 --> 03:31.600 Format here and just say next level. 03:32.910 --> 03:41.520 Just kind of getting practice using these formatting syntax, we'll say level opening the level percent 03:41.520 --> 03:43.440 D closing the level. 03:43.770 --> 03:50.520 We can even have slash N to get a new line here and I can copy the opening and closing for the default 03:50.520 --> 03:51.180 again. 03:53.340 --> 03:57.480 And say causes much more damage. 03:57.780 --> 04:04.470 And then after the text, I just need to replace the percent de with an integer that can be level. 04:05.430 --> 04:11.820 So we can see, you know, what it looks like by using the default format for next level, using the 04:11.820 --> 04:15.560 level format for this percent de, which will be replaced by level. 04:15.570 --> 04:22.350 We can do a new line character inside of our string and then we have the default style here again. 04:22.350 --> 04:29.100 So really just, you know, showing how this stuff works and making sure that it's going to work now 04:29.130 --> 04:32.760 or a gameplay ability can also return a locked description. 04:32.760 --> 04:40.770 So I'm going to have a virtual F string returning function called Get Locked description. 04:41.430 --> 04:44.370 This will also take in an INT 32 called level. 04:44.370 --> 04:49.110 And it's just going to say, you know, ability locked until level, right? 04:49.110 --> 04:54.280 So we'll say return f string, we'll print f. 04:56.610 --> 05:02.160 With text and the text will just be using the default style for now. 05:02.820 --> 05:15.030 And it's going to say ability or we'll say spell locked until level and we'll use percent D And so this 05:15.030 --> 05:18.270 function will take in the level requirement. 05:20.050 --> 05:24.490 So we'll use that to replace percent D here. 05:24.490 --> 05:29.530 So the locked description will just be for a locked spell. 05:30.280 --> 05:32.590 Okay, so we have these functions. 05:32.590 --> 05:39.520 We're going to override them in child ability classes, but for now we just have something to call on 05:39.520 --> 05:42.820 the ability in order to get a description. 05:42.820 --> 05:49.630 But our ability system component is going to need a function that can return a description based on 05:49.630 --> 05:50.980 an ability tag. 05:51.400 --> 05:55.090 So I'm going to open the ability system component class. 05:58.360 --> 06:00.490 Or a ability system component. 06:00.580 --> 06:07.690 So I'd like a function that can get the description and the next level description based on an abilities 06:07.720 --> 06:08.810 ability tag. 06:08.830 --> 06:12.280 So the function can be public. 06:13.060 --> 06:15.400 And I'd like it to return a bool. 06:15.790 --> 06:24.130 That way, if we fail to get a proper description, we'll just return false and this will be get descriptions. 06:25.800 --> 06:30.510 By ability tag and notice I said descriptions plural. 06:30.540 --> 06:34.860 Because we have a description and we have a description for the next level. 06:34.980 --> 06:42.660 So this will take a const gameplay tag by reference called ability tag and it'll also take in an F string 06:42.660 --> 06:45.540 by non-const reference that it can fill in. 06:45.540 --> 06:49.320 And this will be description, we'll call it out description. 06:49.860 --> 06:52.500 And we'll also have another one for the next level. 06:52.500 --> 06:54.570 Description passed in by reference. 06:54.570 --> 06:57.540 We'll call it out Next level Description. 06:59.620 --> 07:02.830 So this function is going to fill in out description and out. 07:02.860 --> 07:04.420 Next level Description. 07:04.420 --> 07:05.920 So how are we going to do that? 07:05.920 --> 07:08.590 Well, let's create the function definition. 07:08.590 --> 07:16.360 And what we need to do is, first of all, check to see if our ability tag is valid, if it has a valid 07:16.360 --> 07:21.460 ability spec, if it's in our activatable abilities, and we'll do that with an If check, we'll say 07:21.460 --> 07:29.830 if we'll make a const f gameplay ability spec that's a pointer, we'll call it spec, I'll call it ability 07:29.830 --> 07:30.310 spec. 07:30.310 --> 07:31.660 I won't be that lazy. 07:33.650 --> 07:38.660 And we're going to call get spec from ability tag passing an ability tag. 07:43.040 --> 07:49.310 So we won't get into the if statement if this is not even a valid ability tag. 07:49.460 --> 07:58.190 Now, if that's the case, I would like to just use a string that says that the ability is locked, 07:58.190 --> 08:00.560 but we do know the ability tag. 08:00.560 --> 08:10.100 So we could get ability info our data asset and take a look at its ability level requirement so we could 08:10.100 --> 08:14.480 get our ability info with you ability info. 08:15.560 --> 08:18.110 We'll call this ability info. 08:20.480 --> 08:30.320 And we can use you or ability system library get ability info passing in a world context object. 08:30.320 --> 08:38.000 I always like to use get avatar actor and with our ability info we can get the level requirement and 08:38.000 --> 08:45.230 that way we can get the locked ability description from our gameplay ability and then we can set our 08:45.230 --> 08:48.590 f string to a locked description. 08:48.590 --> 08:54.950 And I suppose we could just make that locked description here and it doesn't really matter that we have 08:54.950 --> 09:01.400 a get locked description on the ability class because we can set that string to a locked description, 09:01.400 --> 09:08.120 which means if we're going to want to call that get locked description function on or a gameplay ability, 09:08.150 --> 09:12.140 we should just make it static and don't plan on overwriting it. 09:12.140 --> 09:17.570 So I'm going to take virtual off, but I'm going to make it a static function and the static function 09:17.570 --> 09:21.480 will say spell locked until this level, right? 09:21.480 --> 09:26.670 So it's going to be a static function, which means we can call it straight on the Or gameplay ability 09:26.670 --> 09:27.330 class. 09:27.330 --> 09:31.170 So that's what I'm going to do is I'm going to set the description out. 09:31.170 --> 09:32.130 Description. 09:33.800 --> 09:37.910 Equal to you or a gameplay ability. 09:38.150 --> 09:45.080 Double colon get locked Description because it's a static function and we'll pass in the level requirement 09:45.080 --> 09:46.340 from ability info. 09:46.340 --> 09:48.590 So we'll say ability info. 09:49.190 --> 09:56.690 Find ability info for tag passing an ability tag and from that ability info we'll get the level requirement 09:56.690 --> 09:57.770 and pass that in. 09:57.770 --> 10:05.180 And now our out description will just have the locked description and next level description can be 10:05.180 --> 10:05.620 empty. 10:05.630 --> 10:11.120 So we'll say out next level description equals the empty string F string. 10:11.300 --> 10:12.680 That's what we'll do. 10:12.830 --> 10:17.330 And we'll say that in this case we'll return false. 10:19.490 --> 10:28.220 Meaning that we did not find an ability in our activatable abilities and get spec from ability tag. 10:28.220 --> 10:31.250 We'll just say that we have a locked ability. 10:31.250 --> 10:37.550 We'll consider this to be locked and I'll make ability info const and in the case that we do find a 10:37.550 --> 10:45.440 valid ability spec, then we know that it's not a locked ability and we can set the description by getting 10:45.440 --> 10:48.680 our gameplay ability from the ability spec. 10:48.710 --> 10:50.150 So we'll do this. 10:50.150 --> 10:55.580 We'll say you are a gameplay ability or ability, we'll call it that. 10:57.650 --> 11:00.860 Equals a cast to you or a gameplay ability. 11:02.950 --> 11:08.260 And we're going to take our ability spec and get the ability from this ability spec. 11:08.260 --> 11:13.390 So we're going to get the actual ability, the Ue or a gameplay ability. 11:13.660 --> 11:20.110 If we successfully cast to it, then we're going to call those non-static functions on our ability. 11:20.110 --> 11:28.240 We're going to take out description and set it equal to or ability get description and we're going to 11:28.240 --> 11:29.590 pass in the level. 11:29.590 --> 11:36.430 We can get that from the ability spec, so ability, spec level and for our next level description, 11:36.430 --> 11:44.560 we'll set it equal to aura ability, get next level description passing in ability spec level. 11:45.600 --> 11:48.360 Plus, you guessed it, plus one. 11:48.780 --> 11:49.410 All right. 11:49.410 --> 11:51.300 And then we can return. 11:51.300 --> 11:51.930 True. 11:53.090 --> 11:56.600 So this way we'll know the difference between these two outcomes. 11:56.600 --> 12:03.470 But the important thing is that we have a git descriptions by ability tag function that we can use to 12:03.470 --> 12:05.330 get the descriptions. 12:05.330 --> 12:13.280 Whenever a ability changes, either changes its status, changes its level and what have you. 12:13.840 --> 12:20.020 So because we have this function, we can call this function from our spell menu widget controller. 12:20.830 --> 12:27.700 So I'm just going to quickly go to my private folder to UI widget controller, spell menu, widget controller, 12:28.090 --> 12:32.500 and I'm going to look at wherever we're broadcasting spell globe selected delegate. 12:32.530 --> 12:32.860 Why? 12:32.890 --> 12:38.950 Because we're broadcasting these two booleans whenever we've selected a spell globe. 12:38.950 --> 12:44.320 But now when we select a spell globe, we should also get those descriptions and push those up to our 12:44.320 --> 12:48.190 widgets as well so we can set those rich text blocks. 12:48.190 --> 12:49.960 That would be ideal. 12:50.580 --> 12:52.620 So we're going to get the spell menu. 12:52.620 --> 12:56.970 Widget controllers delegate that broadcast to Booleans. 12:57.410 --> 13:01.270 We're also going to broadcast two F strings as well. 13:01.290 --> 13:04.770 So I'm going to add an F string comma. 13:04.770 --> 13:13.410 We'll call this description string and we'll add another F string comma, and we'll call this next level 13:13.410 --> 13:16.260 description string. 13:17.250 --> 13:24.530 And now that spell globe selected signature requires two F strings in addition to two booleans. 13:24.540 --> 13:31.410 We need to pass in strings, so we'll go back to spell menu widget controller Everywhere we're broadcasting 13:31.410 --> 13:35.970 spell globe selected delegate and make sure we pass two strings in. 13:36.150 --> 13:38.370 I'm going to go up to the top and search for it. 13:38.370 --> 13:45.690 So I find the first instance of it, and that's going to be when ability status change has been broadcast. 13:45.720 --> 13:50.680 Now we have the ability tag and our ability system component. 13:50.680 --> 13:58.030 It has the function get descriptions by ability tag that takes a tag and two out parameters for descriptions. 13:58.500 --> 14:05.460 So what we can do is just like we made two booleans and set them with this function, we can make two 14:05.490 --> 14:09.040 F strings and set them with that ability system component function. 14:09.060 --> 14:11.730 So we're going to make an F string called description. 14:12.660 --> 14:15.840 And F string called Next Level Description. 14:18.710 --> 14:20.690 We're going to get RISC. 14:23.170 --> 14:30.640 And we're going to call get descriptions by ability tag and pass in the ability tag and pass in description 14:30.640 --> 14:33.040 and pass in next level description. 14:34.240 --> 14:42.220 And then when we broadcast the delegate, we can pass in description and we can pass in next level description. 14:43.470 --> 14:51.000 And of course we get the red squiggles because you guessed it, this can now be changed to four params 14:51.000 --> 14:51.930 instead of two. 14:53.130 --> 14:54.630 And that's going to fix that. 14:54.810 --> 14:56.970 So now we need to call. 14:57.960 --> 15:03.180 This with two strings every time we broadcast this delegate. 15:03.180 --> 15:05.060 So we're going to find it down here. 15:05.070 --> 15:10.230 When spell points change, we're going to replace this line with these. 15:10.230 --> 15:14.580 For now, we're going to get a string called description and F string. 15:14.580 --> 15:16.140 Next level description. 15:16.140 --> 15:19.410 We're going to call get descriptions by ability tag. 15:19.410 --> 15:21.630 This has to be our selected ability. 15:21.900 --> 15:27.060 So we're going to pass in selected ability, dot ability, and then we'll broadcast. 15:27.060 --> 15:29.250 And I believe that's the only Nope. 15:29.250 --> 15:33.150 There's another place where we're broadcasting that's in Spell Globe selected. 15:33.150 --> 15:42.000 So we also need to do this here to description next level description passing in ability tag. 15:42.000 --> 15:46.830 And then we broadcast those strings up with those booleans. 15:47.100 --> 15:52.230 Now that we've done this, we can handle those two strings in our spell menu. 15:52.230 --> 15:54.210 So let's go back into the editor. 15:54.210 --> 15:55.770 We'll compile and launch. 15:56.530 --> 16:01.150 And we'll get our spell menu open and in the spell menu. 16:02.160 --> 16:05.670 Right here on Spell Globe selected. 16:05.670 --> 16:08.220 We now have two strings that we're receiving. 16:08.340 --> 16:09.870 I'm going to make some room. 16:12.050 --> 16:13.520 And move this out. 16:15.180 --> 16:22.290 And I'm going to take these two strings and set the values for my rich text blocks, which I have here 16:22.320 --> 16:25.200 called Rich Text description and Rich Text. 16:25.230 --> 16:26.750 Next level Description. 16:26.760 --> 16:29.040 So I'm going to get those out here. 16:29.070 --> 16:30.690 Rich Text Description. 16:30.960 --> 16:33.270 And where's the other one? 16:33.270 --> 16:35.130 I might not have made it a variable. 16:35.160 --> 16:36.030 I did not. 16:36.030 --> 16:38.310 So now it's a variable and there it is. 16:39.820 --> 16:43.870 Now for rich text description and next level description. 16:43.870 --> 16:46.500 We just need to call, set, text on them. 16:46.570 --> 16:50.080 So for rich text description, we're going to call, set, text. 16:51.120 --> 16:56.580 The function and we're going to get our description string and hook it straight in. 16:56.580 --> 17:02.370 It's going to be converted from a string to a text, and we're going to do the same thing for next level 17:02.370 --> 17:03.390 Description. 17:05.840 --> 17:10.040 We'll get our next level description string right there. 17:11.860 --> 17:14.320 So now we're setting our descriptions. 17:15.210 --> 17:17.730 So we can compile and save that. 17:18.000 --> 17:23.670 And we should just see some default messages from the aura gameplay ability. 17:24.590 --> 17:32.450 And we do we see default ability name and then Lorem ipsum now it goes off the screen it doesn't wrap 17:32.450 --> 17:32.900 around. 17:32.900 --> 17:36.200 So that's something we can set on our text block. 17:36.680 --> 17:40.820 So I'm going to take this text block and search for wrap. 17:42.360 --> 17:44.330 And auto wrap text. 17:44.340 --> 17:47.550 I'm going to do the same thing for the other one, auto wrap text. 17:47.760 --> 17:48.930 So now. 17:49.620 --> 17:50.550 Saving all. 17:52.240 --> 17:53.590 I can select. 17:53.590 --> 17:55.570 And now we see that it wraps. 17:55.570 --> 18:03.100 And because I typed Lorem ipsum so much, we have our scroll bar because it's got enough text to scroll 18:03.100 --> 18:07.390 and at the very end I said the level, which is one really, really cool. 18:07.390 --> 18:11.130 And then here next level to causes much more damage. 18:11.140 --> 18:12.070 Cool. 18:13.040 --> 18:18.590 And if we level up and upgrade that other ability to eligible. 18:20.510 --> 18:21.590 Like so. 18:22.560 --> 18:26.820 Well, we still see the same thing, so it's not going to do much. 18:26.820 --> 18:33.390 But if we click on all these other ones, they're going to say spell locked until level one because 18:33.390 --> 18:37.860 they don't actually have ability tags set for them. 18:37.860 --> 18:44.610 But what we can do is we can test out that second ability before we upgrade it to eligible. 18:44.610 --> 18:47.220 If I click on it, it says spell locked until level two. 18:47.250 --> 18:53.670 So we know that part works so we can actually see the level requirement when we click on it. 18:53.670 --> 19:00.390 As long as it has a valid ability tag corresponding to an ability in our ability info data asset that 19:00.390 --> 19:04.620 has a level requirement because that's where we're getting our level requirement from. 19:04.980 --> 19:05.790 All right. 19:05.790 --> 19:11.910 So we now have spell descriptions, but we just have a default description on our ability class. 19:11.940 --> 19:15.360 We need to fill this in for our firebolt ability. 19:15.360 --> 19:21.120 So it actually shows some really cool info for the Firebolt and we can also do it for our electrocute 19:21.120 --> 19:22.390 ability as well. 19:22.390 --> 19:23.800 And we'll do that next. 19:23.800 --> 19:26.260 So great job and I'll see you soon.
