WEBVTT 00:07.020 --> 00:07.470 Okay. 00:07.470 --> 00:08.250 Welcome back. 00:08.250 --> 00:14.790 Now, there's an interesting problem, and you don't know about it until you've unlocked another ability, 00:14.820 --> 00:17.670 spent a point on it and then tried to equip it. 00:17.700 --> 00:20.850 You'll see that it clears out anything else that's there. 00:20.880 --> 00:26.820 Now, that's a pretty easy fix and it all comes down to our equipped row button. 00:27.550 --> 00:31.870 You see if the ability tag is none, then we clear the globe. 00:31.870 --> 00:35.920 But we shouldn't do that unless the input tag matches. 00:35.950 --> 00:37.870 So right here we're checking. 00:37.870 --> 00:43.780 If we match the input tag, we should actually check if we match the input tag first. 00:43.840 --> 00:49.540 Otherwise, we're just going to clear every single one of our globes every time. 00:49.540 --> 00:51.490 So we'll have this branch here. 00:53.450 --> 00:59.090 And we'll hook the false up to the rest of what it's doing and the true up to clear globe. 00:59.090 --> 01:04.640 And that's the true for if it's ability is none so that should fix that. 01:04.640 --> 01:08.480 And after that our spell menu should be working. 01:15.050 --> 01:16.010 Let's level up. 01:17.480 --> 01:18.970 Let's upgrade this ability. 01:18.980 --> 01:20.780 Let's equip it to right mouse button. 01:20.780 --> 01:21.870 And there we go. 01:21.890 --> 01:26.990 Now, this is awesome because now I can right click to electrocute. 01:26.990 --> 01:28.970 I can left click. 01:29.000 --> 01:30.710 Of course, with shift. 01:30.740 --> 01:34.640 Our left mouse button requires the shift unless we have a target. 01:34.640 --> 01:35.210 Right. 01:35.300 --> 01:43.820 But we can now take the electrocute ability, press, equip and click on the left mouse button slot 01:43.820 --> 01:46.490 and push that firebolt ability out. 01:46.490 --> 01:52.760 And now it's our left mouse button that does our electrocute and we can take our firebolt and equip 01:52.760 --> 01:58.250 it to the right mouse button and we can really use any of these that we want. 02:00.720 --> 02:01.890 Doesn't matter. 02:01.980 --> 02:06.900 We now have inputs that can be reassigned via the spell menu. 02:06.930 --> 02:14.220 This is actually a pretty big deal and it's something that I've been requested a lot to cover, and 02:14.220 --> 02:15.720 this is just one way to do it. 02:15.720 --> 02:20.790 It's not really a input remapping, extensive system. 02:20.790 --> 02:23.130 It's just for our spell system. 02:23.130 --> 02:29.340 We now have the ability to remap our spells to different inputs and it looks great. 02:30.490 --> 02:32.020 And we can cancel. 02:35.070 --> 02:36.720 And it's pretty robust. 02:37.080 --> 02:40.470 So now our spell menu is actually pretty much complete. 02:40.470 --> 02:46.890 The only thing is when we add new spells, we need to give them descriptions, but other than that, 02:46.890 --> 02:49.680 the spell menu is pretty much done. 02:49.710 --> 02:53.040 We just need to make sure to update our overlay. 02:53.070 --> 02:59.760 Now that's pretty easy because there's a delegate broadcast by the ability system component and that's 02:59.760 --> 03:06.060 what we respond to, to update this right here so we can do the same thing in the overlay. 03:06.120 --> 03:07.730 So what is that? 03:07.740 --> 03:10.380 Delegate It's on ability equipped. 03:10.380 --> 03:12.930 So this is what we're doing. 03:13.050 --> 03:16.440 We need to do the same thing in the overlay widget controller. 03:16.470 --> 03:21.150 So we're going to have an on ability equipped in that class. 03:21.270 --> 03:28.200 So I'm going to go ahead and just close out of all the other tabs except for spell menu, widget controller, 03:28.350 --> 03:36.640 CP, and I'm going to go into my overlay widget controller and make a callback here to bind to that 03:36.640 --> 03:40.950 same delegate and I'm going to give it the same name on ability equipped. 03:40.960 --> 03:43.780 I can just copy the signature. 03:44.320 --> 03:46.720 And an overlay widget controller. 03:46.750 --> 03:49.600 I'll just make it a protected function. 03:49.720 --> 03:52.660 Void on ability equipped. 03:52.990 --> 03:55.360 And let's generate a definition. 03:58.790 --> 04:03.470 Now we need to bind this so we'll get our ability system component. 04:03.770 --> 04:08.720 We're going to want to cast it to aura, ability, system component. 04:08.720 --> 04:11.660 And the first thing I'll do is I'll call, get or ask. 04:14.670 --> 04:17.580 And get our ability equipped delegate. 04:17.790 --> 04:26.490 We're going to add you object with this comma at you overlay widget controller on ability equipped and 04:26.490 --> 04:27.240 there we go. 04:27.970 --> 04:31.480 Now we just need to handle an ability equipped. 04:32.020 --> 04:38.230 I'm going to take my spell menu, widget controller function, copy the whole thing, and then we'll 04:38.230 --> 04:41.290 paste it over and change what we need. 04:41.320 --> 04:43.420 We don't need this line. 04:43.420 --> 04:45.250 We don't have that boolean here. 04:45.850 --> 04:53.260 We do want gameplay tag, so I'm going to include for gameplay tags. 04:53.530 --> 05:02.140 We do want to broadcast last slot info, so we'll broadcast abilities none for that at the previous 05:02.140 --> 05:02.950 slot. 05:03.100 --> 05:09.610 And we also want to get ability info for the current tag and broadcast it at its current slot. 05:09.610 --> 05:14.950 And then we don't need to broadcast this other delegate that was specific to the widget controller for 05:14.950 --> 05:15.950 the spell menu. 05:15.970 --> 05:18.280 So these are the only things we need to do. 05:18.310 --> 05:20.830 This can also be a const function. 05:23.560 --> 05:29.740 So we'll make it const and let's just make sure we're handling this properly in the editor. 05:29.740 --> 05:31.460 So I'm going to close the editor. 05:31.480 --> 05:39.580 Save, selected and relaunch and just see how things work now that we're calling on Ability Equipped. 05:41.230 --> 05:41.740 All right. 05:41.740 --> 05:43.090 We're back in the editor. 05:44.020 --> 05:45.310 Let's press play. 05:45.520 --> 05:48.400 Let's change our spell situation. 05:48.400 --> 05:52.000 And so we got that same white square problem. 05:52.000 --> 05:55.040 Now that we know how to fix it, we can fix it pretty easily. 05:55.060 --> 05:59.290 We have to go to our overlay though, and actually it's not even the overlay. 05:59.290 --> 06:06.090 It's in UI overlay, sub widget health, mana spells, and it's in each of these. 06:06.100 --> 06:08.750 So these are spell globes. 06:09.550 --> 06:10.420 Spell globes. 06:10.420 --> 06:12.730 Let's open that widget class. 06:12.730 --> 06:19.150 So UI spell globes and it's actually the spell globe class. 06:19.360 --> 06:21.370 Let's see what we're doing here. 06:21.370 --> 06:25.870 We're receiving ability info and right here we can check. 06:25.900 --> 06:32.410 If we match the input tag, then we can also check with another branch. 06:33.580 --> 06:37.480 Right here and only false will continue. 06:37.480 --> 06:38.600 And what are we checking? 06:38.620 --> 06:40.900 We're checking the ability tag. 06:41.080 --> 06:44.800 We're seeing if it matches tag exact abilities. 06:44.830 --> 06:45.490 None. 06:46.300 --> 06:49.180 If it does match tag exact abilities? 06:49.210 --> 06:49.850 None. 06:49.870 --> 06:51.880 Then we want to clear the globe. 06:51.910 --> 06:53.740 Let's call Clear Globe. 06:54.660 --> 06:56.850 And just looking at Clear Globe, Yes. 06:56.850 --> 06:59.570 Sets it to a transparent background. 06:59.580 --> 07:01.140 So with that. 07:02.200 --> 07:03.940 We should have things working. 07:04.240 --> 07:05.830 And we do. 07:05.830 --> 07:07.920 And we'll go ahead and level up. 07:07.930 --> 07:09.430 I have to right click now. 07:11.350 --> 07:12.760 Boom leveled up. 07:12.760 --> 07:16.080 Let's upgrade that ability and equip it to. 07:16.510 --> 07:17.470 Uh oh. 07:22.820 --> 07:25.580 Something happened that I didn't quite see. 07:25.610 --> 07:27.200 Let's see what happens. 07:28.340 --> 07:29.870 How can I repro what just happened? 07:29.900 --> 07:37.940 I think I have to put this there and then upgrade inability by Oh, I see a couple of problems. 07:38.240 --> 07:38.690 Okay. 07:38.690 --> 07:47.600 So as soon as I switch to the right mouse button and I fired off, I saw that my cooldown is actually 07:47.630 --> 07:49.900 what's messing things up. 07:49.910 --> 07:53.320 So it appears to be related to the cooldown. 07:53.330 --> 07:55.910 And if we go back to our spell globe. 07:56.790 --> 07:58.560 We'll see that. 07:59.030 --> 08:05.150 We're listening for a cooldown change for the cooldown tag, which once this spell globe has been cleared 08:05.150 --> 08:09.050 out, we should clear out its cooldown tag as well. 08:09.710 --> 08:13.280 So let's go back to receive ability info. 08:14.890 --> 08:23.260 And here, if the ability is matching the input tag for the slot and its abilities, none. 08:23.260 --> 08:30.130 We should set the cooldown tag to an empty tag and that should make sure that it no longer listens to 08:30.160 --> 08:31.720 that old cooldown. 08:31.750 --> 08:41.170 So what I did to repro the issue was equip firebolt to right mouse button and then level up. 08:43.330 --> 08:51.490 Then upgrade, electrocute and equip it to left mouse button and then fire the right mouse button ability. 08:51.490 --> 08:53.830 And we did see that before. 08:53.830 --> 09:00.340 The reason that it put the white texture on the left mouse button slot was because it was still listening 09:00.370 --> 09:01.810 to the same cooldown tag. 09:01.810 --> 09:03.400 So now we've fixed that. 09:05.370 --> 09:06.210 Okay. 09:06.540 --> 09:10.320 And now we can equip things as we see fit. 09:11.030 --> 09:13.100 We can unselect things. 09:17.830 --> 09:19.120 Things look great. 09:19.360 --> 09:27.040 So one last polishing touch that I think I'd like to do is as soon as we've assigned an ability to a 09:27.040 --> 09:31.390 slot, I'd like to deselect what I previously had selected. 09:31.390 --> 09:34.750 I don't want to have to go up there and click it and unselect it. 09:34.810 --> 09:39.880 And also I'd like to play a sound when we equip something. 09:40.030 --> 09:43.480 I think that's also something we could do. 09:43.660 --> 09:48.820 So a couple of polishing last steps and we'll do those in the next video. 09:48.850 --> 09:51.640 Excellent job and I'll see you soon.
