WEBVTT 00:06.780 --> 00:07.740 Welcome back. 00:07.740 --> 00:15.480 So we just created some animations in equipped spells row and we're going to remove these nodes with 00:15.480 --> 00:16.410 event construct. 00:16.410 --> 00:19.080 We just wanted to see what those animations looked like. 00:19.080 --> 00:23.340 I'm going to unhide both of them and just save that. 00:23.990 --> 00:29.720 And close those textures I'm not using and go back and take a look at the spell menu. 00:29.750 --> 00:38.480 Now, what we do when we click on a spell globe is we're enabling or disabling these two buttons. 00:38.600 --> 00:45.140 And if we're selecting a spell globe that's eligible to be equipped and we click on the equip button, 00:45.140 --> 00:49.250 we're going to want to show the user where they need to click next. 00:49.250 --> 00:56.360 They need to click on an offensive spell globe If they are selecting an offensive ability and a passive 00:56.360 --> 00:58.310 one, if they're selecting a passive one. 00:58.640 --> 01:05.360 For this reason, abilities need to know whether or not they're offensive or passive. 01:05.390 --> 01:07.130 They need an ability type. 01:07.750 --> 01:12.580 And this is something that I'd like to keep set in our data asset. 01:12.610 --> 01:17.830 So in Blueprint's ability system data, I want to go to ability info. 01:18.560 --> 01:25.070 And for each gameplay ability I want a ability type tag. 01:25.250 --> 01:29.150 So we're going to add that to our data asset ability info. 01:29.390 --> 01:36.710 Now in addition to that, when we click on the equip button in the spell menu, we need a blueprint 01:36.710 --> 01:42.280 callable function to call on the widget controller to tell it that we're equipping something. 01:42.290 --> 01:49.970 And in addition to that, as soon as we click on the equip button, we'll be playing those animations. 01:50.060 --> 01:55.670 So we have a couple things that we want to add in C plus plus, so we'll close the editor. 01:56.330 --> 02:04.220 And we'll go ahead and open ability system data and get that ability info open and our aura ability 02:04.220 --> 02:07.370 info struct now needs another gameplay tag. 02:07.370 --> 02:10.430 It needs a ability type tag. 02:10.670 --> 02:12.650 So let's go ahead and add that. 02:12.650 --> 02:16.880 I'll put it after the cooldown tag and we'll call this ability type. 02:17.960 --> 02:21.830 So we'll remember to set that for our abilities. 02:21.950 --> 02:27.020 Now we're going to need a blueprint callable function in our widget controller class. 02:27.020 --> 02:30.410 So let's go to UI, widget controller and open spell menu. 02:30.410 --> 02:31.640 Widget controller. 02:31.640 --> 02:36.770 We're going to add a blueprint callable function for when the equip button is pressed. 02:36.770 --> 02:39.230 We'll call it equip button pressed. 02:41.510 --> 02:44.000 And it'll just be blueprint callable. 02:45.080 --> 02:47.180 So we can define this one. 02:48.500 --> 02:51.560 And what is a button press going to do? 02:51.590 --> 02:58.910 Well, for one, we need to tell the widget our spell menu that it needs to start playing an animation. 02:58.940 --> 03:04.340 What we're really doing is waiting for the user to choose an equip selection. 03:04.610 --> 03:08.780 Basically one of the slots down there that we want to equip to. 03:09.170 --> 03:15.230 So we're going to make a delegate to broadcast for this very reason, and it's just going to broadcast 03:15.230 --> 03:16.580 the ability type. 03:16.820 --> 03:21.050 We need to know the type of the ability we currently have selected. 03:21.380 --> 03:26.210 So let's go to spell menu, widget controller and declare a delegate. 03:26.660 --> 03:33.100 So it's going to be a dynamic multicast and it'll just have one param for the ability type. 03:33.110 --> 03:39.200 So we're going to declare dynamic multicast. 03:40.680 --> 03:49.560 And we'll do a delegate one param and I'm going to call this f wait for equip selection. 03:51.510 --> 03:53.970 And we can tack on signature to it. 03:55.720 --> 04:02.200 And it's one param will be a const f gameplay tag and it's going to be the ability type. 04:03.360 --> 04:05.040 So let's make one of these. 04:05.040 --> 04:06.210 We'll add it. 04:06.600 --> 04:07.800 It'll be right here. 04:07.800 --> 04:12.750 And we'll call it wait for equip, delegate. 04:13.740 --> 04:15.720 And we'll make it blueprint assignable. 04:16.440 --> 04:20.610 So that's what we want to broadcast and equip button pressed. 04:20.610 --> 04:23.010 And that means we need to get the abilities. 04:23.040 --> 04:24.240 Ability type. 04:24.360 --> 04:28.680 So to get the ability type, we need the ability info. 04:28.830 --> 04:36.930 Luckily spell menu widget controller has ability info and we can get find ability info for tag and we 04:36.930 --> 04:40.510 need to get the ability info for our currently selected ability. 04:40.530 --> 04:47.460 So we use selected ability dot ability and once we have that ability info we can get the ability type. 04:47.700 --> 04:54.930 So we can say dot ability type and we can store this in a local gameplay tag. 04:55.020 --> 04:58.860 Const gameplay tag ability type. 05:00.060 --> 05:07.350 Now that we have the ability type, we can broadcast our delegate so we can say wait for equipped delegate 05:07.380 --> 05:10.020 dot broadcast ability type. 05:13.460 --> 05:19.850 Now, in addition, I'd like to have a boolean that we can set to true here so we know we're waiting 05:19.850 --> 05:23.720 for the user to select and equip selection. 05:23.750 --> 05:30.650 So I'll make a private boolean called Be Waiting for equip Selection. 05:31.640 --> 05:37.490 It'll be false by default, but as soon as quit button is pressed, we'll set it to true. 05:38.210 --> 05:41.210 So be waiting for equip selection is true. 05:41.240 --> 05:47.190 Now all we need to do is listen for that delegate and call equip button pressed. 05:47.210 --> 05:53.140 So let's compile and go back to the editor and it looks like I'm missing. 05:53.180 --> 05:54.050 Oh, right. 05:54.050 --> 05:56.420 I should have a comma right there. 05:57.080 --> 05:59.060 Okay, let's try that again. 06:01.150 --> 06:04.120 Okay, so we have a couple things we can't forget. 06:04.770 --> 06:11.080 Before I forget, I'm going to go to ability info and set the ability type to these two abilities. 06:11.100 --> 06:16.020 They need to be in abilities type offensive. 06:16.050 --> 06:18.280 They're both offensive abilities. 06:18.330 --> 06:24.060 So abilities type offensive and we can save and close out of that. 06:24.390 --> 06:29.250 Now next, our spell menu needs to listen to a delegate. 06:29.640 --> 06:34.830 So right here, where we're binding to a delegate already on the spell menu. 06:34.830 --> 06:36.030 Widget controller. 06:36.120 --> 06:38.610 I'd like to bind another one. 06:38.820 --> 06:43.500 Now, this stuff here, this could be easily collapsed to a function. 06:43.500 --> 06:45.750 We're setting description texts, right? 06:45.750 --> 06:51.450 So I'm going to right click collapse two function and just call this set descriptions. 06:53.660 --> 06:53.990 Mike. 06:53.990 --> 06:55.280 So that looks good. 06:56.290 --> 07:02.860 And after that, we're going to get BP spell menu, widget controller, and we're going to look for 07:02.890 --> 07:03.160 that. 07:03.190 --> 07:05.050 Wait for equip delegate. 07:09.220 --> 07:14.470 And this one, I think, can go down on a new line right there. 07:14.470 --> 07:16.810 So I'm going to add a new pin. 07:18.240 --> 07:21.330 And just make sure these don't get out of hand. 07:22.870 --> 07:25.660 So this will now go into the then three. 07:26.580 --> 07:32.100 And then right here, we can decide what happens for our weight, for equip, delegate. 07:32.340 --> 07:36.990 Now our equip spell row has our offensive selection boxes. 07:38.210 --> 07:45.290 With animations, offensive selection, animation, passive selection, animation and so on. 07:45.290 --> 07:52.130 And as soon as we have broadcast this delegate, we've broadcast the ability type for our currently 07:52.130 --> 07:58.400 selected ability and we can check to see if that ability type is offensive or passive. 07:58.550 --> 08:06.830 So what I'd like to do is handle what we do in response to this in a function called on wait for equip. 08:07.500 --> 08:09.570 So let's make that function. 08:09.690 --> 08:16.980 We'll call it on wait for equip and it'll take a gameplay tag as an input. 08:18.650 --> 08:22.610 So we'll change this input type to gameplay tag. 08:25.180 --> 08:27.460 And it's going to be ability type. 08:30.900 --> 08:37.380 We'll compile and save that, and then we'll just call this nice little function on wait for equip and 08:37.380 --> 08:39.660 pass in the ability type. 08:40.740 --> 08:43.770 So what do we do in on wait for equip? 08:43.980 --> 08:50.100 Well, first I want to check to see if the tag is the offensive ability type. 08:50.100 --> 08:53.520 So we're going to say matches tag exact. 08:54.670 --> 09:01.630 Or match his tag with exact match, and I'm going to see if it's equal to abilities type offensive. 09:02.410 --> 09:08.410 Now, whether or not it is is just going to be a Boolean variable I'm going to promote this to it'll 09:08.440 --> 09:12.400 be a local variable called is offensive. 09:14.870 --> 09:20.240 So if the gameplay tag is offensive, so will our boolean be? 09:20.600 --> 09:23.120 Now we can branch off based on this. 09:23.120 --> 09:29.810 But before we do, no matter which one it is offensive or passive, I want to disable the equip button 09:29.810 --> 09:33.200 and the spell point button until we're done waiting. 09:33.200 --> 09:34.700 So we're going to take button equip. 09:34.700 --> 09:36.770 Actually, we don't need to take those buttons. 09:36.770 --> 09:41.690 We have a function that can set buttons enabled. 09:41.690 --> 09:44.930 We're going to call that and set them both to false. 09:44.930 --> 09:50.120 And after that, now we can branch based on is offensive. 09:53.640 --> 09:55.320 So is offensive. 09:55.350 --> 09:58.380 Will be true if it's the offensive ability type. 09:58.380 --> 10:05.670 And if that's the case, we want to take our equipped spell row and get its offensive animation. 10:05.880 --> 10:10.020 So get offensive selection animation and play it. 10:10.020 --> 10:13.020 So we're going to take that and use play animation. 10:20.370 --> 10:24.990 And for loops to play, we're going to use zero because we want this to loop. 10:27.720 --> 10:33.870 Now, on the other hand, if it's not offensive, then we're going to play the passive version. 10:33.870 --> 10:35.880 So we're going to get equipped spells row. 10:38.940 --> 10:41.400 And get passive. 10:41.940 --> 10:44.700 Selection animation, and we're going to play that. 10:48.140 --> 10:49.220 Instead. 10:53.430 --> 10:54.840 Okay, so that's it. 10:55.600 --> 10:58.450 So that handles the delegate. 10:58.480 --> 11:00.610 We're going to go ahead and comment this. 11:00.640 --> 11:04.330 We'll say wait for equipped delegate. 11:06.540 --> 11:11.310 And with that, we just need to call the function. 11:12.480 --> 11:15.280 That we created for when we press the equip button. 11:15.300 --> 11:17.010 Equip button pressed, it's called. 11:17.130 --> 11:22.650 And we can do that right after our spend point button pressed delegate. 11:22.650 --> 11:25.320 So we're going to get our button equip. 11:27.350 --> 11:29.360 We're going to get its button widget. 11:29.360 --> 11:30.560 So get button. 11:32.920 --> 11:34.480 We're going to bind to Onclicked. 11:34.480 --> 11:36.880 So assign Onclicked. 11:38.580 --> 11:39.510 We'll hook that up. 11:40.910 --> 11:46.760 And we'll get our spell menu, widget controller and call equip button pressed. 11:48.780 --> 11:50.010 Just like that. 11:51.240 --> 11:53.340 And this gets a comment as well. 11:53.640 --> 11:56.790 It says equip button pressed. 12:02.450 --> 12:09.950 Okay, so now when we press the equip button, we should be able to see those animations. 12:10.040 --> 12:13.670 Now by default, we see them anyway. 12:13.940 --> 12:17.810 But if I press the button, nothing happens. 12:18.500 --> 12:26.450 And that is because if we look at our play animation nodes, they don't have a user widget object reference. 12:26.450 --> 12:28.510 So we do need to pass one in. 12:28.520 --> 12:30.830 That's going to be the equip spells row. 12:30.890 --> 12:37.000 So let's make sure to pass that in to Target before trying to play the animation. 12:37.010 --> 12:40.880 So if we click, then we see that we play the animation. 12:40.880 --> 12:45.740 Now we should set the render opacity to both of these to zero by default. 12:45.740 --> 12:47.870 So we'll go ahead and do that. 12:47.870 --> 12:50.180 So we don't see those big ugly boxes. 12:50.180 --> 12:54.050 We only want to see them when they're animated like so. 12:56.580 --> 13:00.270 So now we have something showing us we need to click right here. 13:00.360 --> 13:04.180 Now notice that we can't click right here anymore. 13:04.200 --> 13:11.220 What's giving me the hint that I can't click on these buttons is they're not highlighting and I'm moving, 13:11.220 --> 13:11.520 right? 13:11.520 --> 13:18.390 So what I need to do is take both of these and set their visibility to. 13:19.280 --> 13:20.690 Not hit testable. 13:20.720 --> 13:21.680 Both of them. 13:23.100 --> 13:25.680 That way we can still click on those buttons. 13:29.100 --> 13:30.060 Perfect. 13:32.140 --> 13:37.960 Now, we can't really test the passive abilities right now because, well, we don't have the ability 13:37.960 --> 13:38.830 to equip them. 13:38.830 --> 13:42.820 We don't really have any valid ability tags for them. 13:42.820 --> 13:47.440 But we do have these and if we go ahead and level up. 13:49.120 --> 13:52.940 And we take this eligible ability and spend a point on it. 13:52.960 --> 13:55.800 Well, now we can click on equip for this one. 13:55.810 --> 13:58.420 So we have the ability to equip. 13:58.420 --> 14:02.440 Now, the last thing I'd like to handle is canceling this animation. 14:02.440 --> 14:05.770 If we say select a different ability. 14:05.800 --> 14:09.220 So basically when we first select an ability. 14:10.050 --> 14:12.750 Or if we deselect an ability. 14:13.050 --> 14:20.850 So on selecting and deselecting an ability, we should cancel all animations if they're playing on this 14:20.850 --> 14:21.750 row here. 14:24.040 --> 14:33.310 So for that I need another delegate that also takes in the ability type, just like wait for equip delegate. 14:33.340 --> 14:36.570 We're going to make one to stop waiting for equip. 14:36.580 --> 14:42.040 So it'll also pass through a gameplay tag for the ability type. 14:42.130 --> 14:44.620 So let's go ahead and make one of those. 14:45.430 --> 14:52.810 And we can just use the same signature, wait for equip selection signature, and we're going to call 14:52.810 --> 14:55.900 this one stop waiting for equip delegate. 14:55.900 --> 15:00.550 So we're going to call it stop waiting for equip delegate. 15:02.490 --> 15:06.190 And we need to broadcast this in a couple situations. 15:06.210 --> 15:14.970 One is in Globe Deselect, we need to broadcast this and we need to know what the ability type is before 15:14.970 --> 15:16.110 we broadcast it. 15:16.110 --> 15:23.850 So we need an gameplay tag called ability type for the ability type. 15:23.850 --> 15:33.690 And it's going to be our selected ability type and we can get our ability info, data asset and call 15:33.690 --> 15:38.310 find ability info for tag using selected ability dot ability. 15:39.720 --> 15:42.090 And from that we can get the ability type. 15:42.300 --> 15:47.700 So now that we have the selected ability type, we can broadcast stop waiting for equip, delegate, 15:48.750 --> 15:51.180 passing in selected ability type. 15:53.550 --> 15:59.460 So we very much need to know that ability type when we want to stop playing an animation, right? 15:59.490 --> 16:06.100 Now we also want to do this same thing when we're selecting one of our spell globes. 16:06.120 --> 16:11.100 So right here in Spell Globe selected, I want to do this very same thing. 16:11.100 --> 16:18.060 So I'm going to paste these two lines, except I really only need to use the ability tag so I can find 16:18.060 --> 16:20.910 ability info for ability tag. 16:20.910 --> 16:26.790 We can get its ability type here and we can broadcast stop waiting for equip, delegate passing in that 16:26.790 --> 16:27.960 ability type. 16:28.140 --> 16:34.890 So if we're selecting a different ability, we need to actually hit equip before we go and play those 16:34.890 --> 16:35.790 animations. 16:35.790 --> 16:37.890 In the meantime, we stop playing them. 16:37.890 --> 16:41.820 So let's handle this delegate in the spell menu. 16:43.200 --> 16:45.150 So back to the spell menu. 16:46.390 --> 16:48.960 We're going to bind now to this one. 16:48.970 --> 16:51.910 We can do it right after wait for equip delegate. 16:51.910 --> 16:54.280 So we'll get the spell menu. 16:54.280 --> 16:55.450 Widget controller. 16:56.830 --> 16:59.620 And a sign Stop waiting for equip delegate. 17:00.650 --> 17:03.290 Now this will be similar to on wait for equip. 17:03.290 --> 17:10.850 In fact, I want to play those animations in our equip spells row to hide the offensive box and the 17:10.850 --> 17:14.630 passive box based on the ability type passed in. 17:14.660 --> 17:19.370 So I'm going to make a function for stop waiting for equip delegate. 17:19.400 --> 17:28.160 So instead of on wait for equip, we're going to have a new function called Stop waiting for equip. 17:29.720 --> 17:31.640 This will take a gameplay tag. 17:37.900 --> 17:40.780 It's going to be the ability type. 17:44.750 --> 17:50.510 And we're going to check if it matches tag exact offensive. 17:50.510 --> 17:57.320 So abilities type offensive and this will also have a local variable called is offensive. 18:03.950 --> 18:10.540 Now for this one, if we have any animations playing, we want to stop them on the equipped spell row. 18:10.550 --> 18:16.550 So we're going to get the equipped spell row and we can call stop all animations. 18:17.940 --> 18:21.570 And after that we can use a branch. 18:22.200 --> 18:24.180 Checking is offensive. 18:32.900 --> 18:42.620 And if it's true, we can get our equip spells row and get hide offensive box and play that animation. 18:42.620 --> 18:47.510 But if it's false, we'll get hide passive box. 18:48.400 --> 18:55.660 So we'll take that widget animation and call play animation on it and we have to pass the widget itself 18:55.660 --> 18:56.440 in. 18:56.740 --> 19:03.640 We only want to play one loop this time, so if it's an offensive ability type, we're going to hide 19:03.640 --> 19:05.080 the offensive box. 19:05.080 --> 19:09.250 And if it's a passive, we're going to hide the passive box. 19:15.800 --> 19:19.940 So we'll just play this animation once and then stop. 19:20.790 --> 19:22.260 And that's going to fade it out. 19:22.260 --> 19:27.810 So we're going to call stop waiting for equip and response to that delegate. 19:29.750 --> 19:31.880 And we'll pass in the ability type. 19:32.390 --> 19:34.370 Let's just see if this works. 19:37.480 --> 19:38.170 Okay, right away. 19:38.170 --> 19:41.020 I'm seeing that we do play it when we select it. 19:41.050 --> 19:43.960 We should only play it if something is currently equipped. 19:43.960 --> 19:44.350 Right. 19:44.350 --> 19:51.220 But if we press the equip button and we have that animation going and we select something else, it 19:51.220 --> 19:52.120 stops it. 19:52.120 --> 19:57.700 And if we have it going and we deselect the self, it also stops it. 19:58.060 --> 20:03.730 So we just need to make sure we don't play the animation if it's not already playing. 20:04.030 --> 20:05.950 Luckily we know when that is. 20:05.950 --> 20:08.830 It's when we're waiting for an equip selection. 20:08.830 --> 20:10.780 We even have a boolean for it. 20:10.930 --> 20:16.690 So what we'll do is every time we're about to broadcast, stop waiting for equip delegate. 20:16.720 --> 20:21.010 We'll only do so if we're currently waiting for an equip selection. 20:21.010 --> 20:25.270 That's the only time that we're playing those animations. 20:25.270 --> 20:32.680 So we're going to wrap them in if be waiting for equip selection and that's going to be where we broadcast 20:32.680 --> 20:39.080 it here and spell Globe selected and where we broadcast it in Globe Deselect. 20:39.080 --> 20:44.720 So right here, we'll only do this if we're waiting for equip selection. 20:45.080 --> 20:51.350 So if be waiting for equip selection, then we'll broadcast these. 20:54.250 --> 21:01.450 Now, in addition to this, we should also set this Boolean back to false so we can say be waiting for 21:01.450 --> 21:05.530 equip selection equals false and both of these cases. 21:06.560 --> 21:13.010 So we're going to stop waiting for equip, delegate, and we're also going to set that Boolean to false. 21:14.710 --> 21:16.810 And we can test this out. 21:17.170 --> 21:22.870 We'll go ahead and select the Firebolt and click on Equip. 21:22.900 --> 21:26.100 We see the animation, we can deselect it. 21:26.110 --> 21:33.670 It goes away if we select it again, it does not play until we click equip again and then deselecting 21:33.670 --> 21:33.760 it. 21:33.760 --> 21:34.840 It goes away. 21:38.070 --> 21:44.880 If we have the equip animation going and we select something else, it goes away and doesn't come back. 21:44.970 --> 21:47.400 And finally, let's go ahead and just. 21:48.320 --> 21:49.520 Get this one. 21:51.950 --> 21:53.030 There we go. 21:53.910 --> 21:57.120 So I'm going to have it playing and select this one over here. 21:58.990 --> 21:59.440 Okay. 21:59.440 --> 22:00.880 We'll spend a point on it. 22:00.910 --> 22:02.110 We'll click equip. 22:02.840 --> 22:04.250 We can cancel it. 22:07.200 --> 22:09.870 Okay, We're getting the behavior we want. 22:10.900 --> 22:11.500 Excellent. 22:11.530 --> 22:13.010 We're one step closer. 22:13.030 --> 22:21.580 So now that we can click on Equip and it's waiting for us to click down here, the next step is to handle 22:21.580 --> 22:23.470 what happens when we click down here. 22:23.470 --> 22:32.320 And that's going to involve reassigning the input tag for an ability, if it has one, or assigning 22:32.320 --> 22:40.000 an input tag to an ability for the first time and actually making that ability have the status of equipped 22:40.000 --> 22:41.350 if it's not already. 22:41.380 --> 22:45.220 So that's the next thing we need to do and we'll do that next. 22:45.370 --> 22:46.420 I'll see you soon.
