WEBVTT 00:07.240 --> 00:08.350 Welcome back. 00:08.350 --> 00:13.090 Now in this video we're going to look at one issue I noticed while testing. 00:13.090 --> 00:18.850 And this is just one of those things that pops up that you may have missed in development. 00:18.850 --> 00:22.600 I'm going to show you the issue and we can repro it this way. 00:22.600 --> 00:24.100 I have my. 00:25.310 --> 00:29.000 Fireblast assigned to slot two. 00:29.270 --> 00:33.860 I'm going to assign it to my right mouse button so I can see it here with my abilities. 00:33.860 --> 00:34.910 Menu open. 00:35.420 --> 00:42.800 Now, this is not an issue if we're disabling input while these menus are open, which is the default 00:42.800 --> 00:44.090 state that I'd like to have. 00:44.090 --> 00:48.590 But we have input possible for testing purposes. 00:48.590 --> 00:53.270 And this issue only pops up with the menu open. 00:53.270 --> 00:54.860 And I'm going to show you what happens. 00:54.860 --> 01:02.090 I'm going to activate this ability Fireblast which has a long cooldown like five seconds or so. 01:02.090 --> 01:08.300 And during that cooldown before the cooldown is over, I'm going to reassign Fireblast to a different 01:08.300 --> 01:13.400 slot, such as the left mouse button, and that's going to make my right mouse button vacant. 01:13.400 --> 01:19.490 It's going to be empty, and it's going to still be updating the cooldown timer. 01:19.490 --> 01:23.690 That's because, well, we're never actually telling it not to. 01:23.690 --> 01:25.460 So I'm going to show you the issue. 01:25.460 --> 01:29.930 I'm going to cast the spell and equip to the left mouse button. 01:33.030 --> 01:33.660 I was too late. 01:33.660 --> 01:34.770 I'm gonna try again. 01:36.980 --> 01:37.610 There we go. 01:37.610 --> 01:44.870 So we have the cooldown and as soon as it's done now we're setting this to a blank texture. 01:44.870 --> 01:50.810 And that's because we're setting the render opacity for the texture back to one, but it no longer has 01:50.810 --> 01:52.190 a valid texture. 01:52.490 --> 02:00.260 So really what we should be doing is first of all, not setting this back if we've reassigned the ability 02:00.260 --> 02:01.430 somewhere else. 02:01.430 --> 02:08.240 And we should also stop showing that countdown value, we can even stop the countdown altogether if 02:08.240 --> 02:12.410 we've reassigned this ability to somewhere else. 02:12.560 --> 02:15.860 So how do we know we've reassigned the ability? 02:15.860 --> 02:17.660 Well, let's open our spell globe. 02:17.660 --> 02:21.200 Not the spell globe button, just the regular spell globe. 02:21.200 --> 02:23.510 This is the one that responds to cooldowns. 02:26.310 --> 02:31.620 Now, if we're in the cool down here, we know that we have a cooldown timer handle we can clear and 02:31.620 --> 02:33.360 invalidate in any time. 02:33.780 --> 02:40.020 So how do we know when we've reassigned this ability somewhere else and this globe should be empty? 02:40.290 --> 02:46.830 Well, we receive ability info, and when we receive ability info that matches with our input tag, 02:46.830 --> 02:49.860 we're checking to see if it's equal to abilities none. 02:49.860 --> 02:52.710 If it's ability is none, we clear the globe. 02:52.710 --> 02:54.690 We can do lots of things here. 02:54.690 --> 03:00.660 We can also clear and invalidate the timer so that we never reach the end of that timer. 03:00.840 --> 03:02.550 Our timer is called. 03:04.650 --> 03:08.820 Cool down timer handle so and receive ability info here. 03:08.820 --> 03:11.250 We can take cool down timer handle. 03:14.420 --> 03:16.820 And we can clear and invalidate the timer. 03:17.090 --> 03:20.660 So clear and invalidate timer by handle. 03:20.900 --> 03:25.580 And now we'll never reach the end of that cooldown timer. 03:27.290 --> 03:29.660 Let's go ahead and see how this works. 03:29.660 --> 03:33.350 So I'm going to assign the ability to the right mouse button. 03:33.350 --> 03:37.370 And I'm going to cast the spell and then assign it to somewhere else. 03:37.370 --> 03:38.120 Here we go. 03:40.870 --> 03:43.570 Okay, so we've stopped the timer. 03:43.570 --> 03:49.630 We also need to stop showing that countdown text, so let's take care of that as well. 03:50.990 --> 03:58.070 So what we can do is we can get our countdown text and I can't remember what it's called. 03:58.720 --> 04:00.730 Text cooldown is what it's called. 04:01.940 --> 04:03.890 So we can get text cooldown. 04:07.560 --> 04:12.870 And I think the way that we're clearing this is by setting its render opacity. 04:12.870 --> 04:15.360 But I want to make sure I'm doing this consistently. 04:15.390 --> 04:16.290 If we go to update. 04:16.290 --> 04:17.610 Cooldown timer. 04:17.610 --> 04:19.140 Text cooldown. 04:19.720 --> 04:21.760 We set default state. 04:22.030 --> 04:25.450 And yes, we're setting render opacity to zero. 04:25.450 --> 04:30.640 So back in receive ability info I'm going to call set Render Opacity. 04:32.350 --> 04:34.030 And set it to zero here. 04:34.060 --> 04:34.690 Okay. 04:34.690 --> 04:36.520 Let's try to repro the issue again. 04:37.620 --> 04:40.080 Equipping to right mouse button. 04:40.580 --> 04:45.950 Casting and re-equipping and it looks fine and that cooldown has stopped. 04:45.950 --> 04:50.330 And if I assign something else here, then we now have something else here. 04:50.330 --> 04:52.220 So that fixes that issue. 04:52.220 --> 04:57.920 Now these are these little problems that can pop up, and they're kind of hard to catch while you're 04:57.920 --> 04:58.790 developing. 04:58.790 --> 05:01.670 And they just sort of pop up in testing. 05:01.670 --> 05:07.160 And that's partially why testing is so important because issues like this pop up. 05:07.520 --> 05:12.890 So it's possible during testing you may find other small issues here and there. 05:12.890 --> 05:20.600 And it's really just a skill that you have to develop finding these edge cases and figuring out solutions 05:20.600 --> 05:21.320 for them. 05:22.130 --> 05:22.640 All right. 05:22.640 --> 05:24.170 That's going to conclude this video. 05:24.170 --> 05:25.820 And I'll see you in the next one.
