WEBVTT 00:00.040 --> 00:02.880 Now what we need to do, we need to call the function. 00:02.880 --> 00:07.440 So basically once we're going to click on this jump button we want to jump. 00:07.440 --> 00:10.160 So we need to call the jump function. 00:10.160 --> 00:16.000 So if I move over to my hierarchy then canvas then UI and then select this jump button. 00:16.000 --> 00:17.400 Then go over to Inspector. 00:17.400 --> 00:18.480 Scroll down. 00:18.480 --> 00:21.080 We need to call the function right over here. 00:21.080 --> 00:23.760 So once we're going to click on this jump button. 00:23.760 --> 00:25.640 So we need to call the function here. 00:25.840 --> 00:29.760 And we do know that we have done inside our player skip. 00:29.960 --> 00:33.800 Uh basically we need to select our player game object in the hierarchy. 00:34.200 --> 00:39.000 So I'm going to select my player game object in the hierarchy I have it over here. 00:39.000 --> 00:41.480 So let's select that and let's open up the player. 00:41.480 --> 00:44.320 Skip in Inspector by double clicking on it. 00:44.760 --> 00:48.760 And if we scroll down we have the jump function. 00:48.800 --> 00:50.160 Something over here. 00:50.160 --> 00:50.960 We need to find it. 00:50.960 --> 00:54.240 So as you can notice we have it over here. 00:54.240 --> 00:59.320 And make sure you just mark your function as public so we can call through a button. 00:59.320 --> 01:04.570 So what we need to do we need to call the function uh we need to call this jump function. 01:04.770 --> 01:07.330 And what jump function is really doing. 01:07.370 --> 01:14.770 It's basically jumping our player, as you can notice in the y axis and basically in the y axis and 01:14.770 --> 01:15.490 in the zero. 01:15.610 --> 01:16.610 Uh sorry. 01:16.650 --> 01:18.210 In the x axis zero. 01:18.410 --> 01:19.930 So let's call the function. 01:19.930 --> 01:23.930 So let's move over to unity and let's select our jump button. 01:23.930 --> 01:28.770 So for that I'm going to move over to canvas UI and select this jump button. 01:28.770 --> 01:30.170 Let's go over to Inspector. 01:30.170 --> 01:32.810 Scroll down to the bottom says Button component. 01:32.810 --> 01:35.090 And let's click on this plus icon. 01:35.090 --> 01:39.650 So we need to drag the GameObject in which GameObject the script is sitting on. 01:39.650 --> 01:42.930 And we do know we have done inside our player script. 01:42.930 --> 01:49.170 So we're gonna drag our player GameObject right over here because the player script is sitting on our 01:49.170 --> 01:50.730 player GameObject. 01:50.730 --> 01:54.090 So I'm gonna move over to my other stuff. 01:54.090 --> 01:55.450 So I'm going to select my player. 01:55.490 --> 01:58.290 Let's drag it there and it says no function. 01:58.290 --> 01:59.610 So let's click on it. 01:59.610 --> 02:04.570 Let's go to Player script right over here in the bottom we can notice. 02:04.930 --> 02:09.620 And inside our player script, we can see we created the jump function. 02:09.620 --> 02:10.980 So we're going to choose that. 02:11.180 --> 02:12.700 So now we have chosen. 02:12.700 --> 02:18.740 So if we click on this play button and then try to click on this jump button, you will see our player 02:19.180 --> 02:19.820 game object. 02:19.820 --> 02:21.860 Just gonna jump right away. 02:22.500 --> 02:29.740 So uh, we're gonna basically as, as soon as we're gonna click on this jump button, we can just make 02:29.740 --> 02:30.420 the jump. 02:30.540 --> 02:34.380 So if I just click on this jump button, as you can notice, we're jumping. 02:34.380 --> 02:40.900 But the problem is that we can jump as many times we want, which we really don't want, and we do know 02:40.900 --> 02:42.540 we're doing inside that. 02:42.620 --> 02:50.660 Uh, basically our, uh, once we click on this space button on our keyboard, we basically making the 02:50.660 --> 02:51.020 jump. 02:51.020 --> 02:52.380 And there we checking. 02:52.380 --> 02:55.380 So instead of doing that we're going to do something else. 02:55.380 --> 03:01.180 So basically what we need to do we need to get out of play mode and then move over to player script. 03:01.180 --> 03:05.140 So over here as you can see we just making our jump. 03:05.140 --> 03:09.630 So before we jump we also want to check if we are grounded or not. 03:09.670 --> 03:14.310 If this player is touching the ground, then we want to jump. 03:14.350 --> 03:16.670 Else we're not gonna jump at all. 03:16.670 --> 03:23.630 And we do know that if we move over to our skip and then move over to our update function, uh, right 03:23.630 --> 03:24.350 over here. 03:24.390 --> 03:29.990 As you can notice, if we press down space key at the same time, total jump is zero. 03:30.030 --> 03:34.510 F basically means we have, uh, more than one jump. 03:34.670 --> 03:39.070 So instead of checking over here, we're going to check it there. 03:39.110 --> 03:41.310 So what we're going to do we're going to remove this. 03:41.470 --> 03:46.270 So let's remove this and also remove this total jumps right over here. 03:46.390 --> 03:49.590 And we're gonna do it inside our jump function. 03:49.750 --> 03:56.190 So before we jump what we want to check, we just want to check if our jump is greater than zero. 03:56.230 --> 03:57.550 If so we're going to check. 03:57.550 --> 03:59.150 So before we make our jump. 03:59.150 --> 04:01.950 So let's make first bracket and some curly brackets. 04:01.990 --> 04:04.030 So what we want to check over here. 04:04.030 --> 04:09.350 We basically want to check if our total jumps if it's greater than zero f. 04:09.350 --> 04:13.110 And we do know that in the start of the game we just doing it. 04:13.110 --> 04:17.910 So what we're going to do now, we're going to put this line of code by Ctrl X for cut. 04:17.950 --> 04:25.270 We're going to paste inside Ctrl B basically what we're doing, we instead of doing inside our uh input 04:25.270 --> 04:27.350 dot get space right over here. 04:27.390 --> 04:32.390 We basically doing here inside our jump function as you can notice. 04:32.550 --> 04:37.630 And after jumping what we need to do we need to subtract our total jumps. 04:37.630 --> 04:41.910 So we will subtract total jumps minus minus basically. 04:41.950 --> 04:43.390 So subtracting one. 04:43.590 --> 04:50.590 So before we jumping uh what we're doing we basically checking if our total jumps is greater than zero 04:50.630 --> 04:50.950 f. 04:51.110 --> 04:56.110 And in the start of the game we just set total jumps to two, something like that. 04:56.110 --> 05:00.710 And we do know that two is greater than zero f or one something like that. 05:01.190 --> 05:03.230 So the condition getting true. 05:03.230 --> 05:04.710 So that's why we're going to jump. 05:04.710 --> 05:08.150 And after jumping we just subtracting total jumps. 05:08.150 --> 05:12.760 And we do know that this total jumps somehow it's going to hit zero. 05:12.960 --> 05:20.080 And when it hits zero, if we move over to our update function when it is zero, it's ground is true. 05:20.080 --> 05:23.360 Basically means player basically standing on this ground. 05:23.400 --> 05:28.040 Then what we're doing, then we're setting total jumps again to our extra jumps. 05:28.040 --> 05:30.000 And by default we have set two. 05:30.160 --> 05:32.360 So this right over here total jumps. 05:32.360 --> 05:35.800 Getting one more time two and two is greater than zero. 05:36.080 --> 05:37.800 So the condition getting true. 05:37.800 --> 05:41.440 So that's why we will able to jump for the next time as well. 05:41.680 --> 05:46.120 And now what we need to do we need to press down Ctrl s to save our script. 05:46.120 --> 05:48.080 And now let's move over to unity. 05:48.400 --> 05:50.280 Basically we're doing the same things. 05:50.280 --> 05:57.880 And instead of doing if that if condition basically inside our update function, we basically turn inside 05:57.880 --> 05:59.680 our jump function. 05:59.680 --> 06:01.400 So basically that is the cool thing. 06:01.480 --> 06:08.280 Now even if we press down space key and also this jump button, it's going to do the same thing because 06:08.280 --> 06:10.400 we're doing inside jump function. 06:10.400 --> 06:11.280 So that's why. 06:13.080 --> 06:14.520 So let's have a look. 06:15.250 --> 06:16.650 So just wait a moment. 06:18.970 --> 06:23.330 So once our compilation is done, we can just check that out. 06:23.810 --> 06:28.330 So I'm going to click on this play button in the top in order to play our game. 06:28.330 --> 06:30.330 And let's have a look on this. 06:30.410 --> 06:34.650 So as soon as we're gonna click on this jump button we will be able to jump. 06:34.650 --> 06:42.370 And once we jump two times then we're not gonna jump at all until and unless we hit our ground one time. 06:42.370 --> 06:47.370 So if I just click on this jump button, as you can notice, we not able to jump anymore. 06:47.730 --> 06:54.330 Uh, basically we jumping three times, but more than three times we not able to do it and we able to 06:54.330 --> 07:01.010 do it once this player game object touching this ground then we just resetting total jumps to our extra 07:01.010 --> 07:01.450 jump. 07:01.730 --> 07:08.530 And if I do the same thing with my space key, we can see it's doing the same thing because we have 07:08.530 --> 07:11.370 done all of the things inside that jump function. 07:11.370 --> 07:12.410 So that's why. 07:12.730 --> 07:15.410 And we're gonna talk about this attack button. 07:15.410 --> 07:18.060 Now if I just left click on my mouse button. 07:18.060 --> 07:22.060 We can see we're just playing our attack animation for now. 07:22.060 --> 07:23.180 I'm gonna remove that. 07:23.180 --> 07:29.180 If I just click left mouse button, I don't want to play the attack animation, but if I click on this 07:29.220 --> 07:31.380 attack button then I want to do it. 07:31.380 --> 07:37.180 So for that, let's get out of play mode and I'm gonna move over to my script and let's move over to 07:37.220 --> 07:44.860 our update function, where we basically playing our attack animation right over here, as you can notice. 07:44.860 --> 07:48.420 So I'm going to make this one comment by double forward slash. 07:48.420 --> 07:52.660 And we do know that the comments basically don't interrupt our code. 07:52.780 --> 07:58.020 And if I press down Ctrl s then move over to unity and then click on this play button. 07:58.020 --> 08:04.340 You will notice if we click the left mouse button, we're not going to able to play the attack animation 08:04.340 --> 08:05.660 clip anymore. 08:06.060 --> 08:13.300 Uh, so for testing purpose purpose I'm just doing that and we're gonna hook that with this attack button. 08:13.300 --> 08:18.620 So once we're gonna click on this attack button, I want to play the attack animation of this player 08:18.660 --> 08:19.550 game object. 08:19.550 --> 08:25.270 So if I just go add and then click on this play button and then try to click left mouse button, you 08:25.270 --> 08:29.670 will notice our player not gonna play attack animation at all. 08:29.870 --> 08:33.430 So for testing purposes I'm just doing that. 08:33.430 --> 08:37.710 But once we're gonna click on this attack button then we just want to do that. 08:37.710 --> 08:40.870 As you can notice, I'm just clicking the left mouse button. 08:40.870 --> 08:44.870 It's not playing the jump basically attack animation. 08:45.110 --> 08:52.110 But once we click on this, uh, you can simply say this attack button will not able to play our attack 08:52.110 --> 08:52.870 animation. 08:52.870 --> 08:58.150 So basically what we need to do, we need to hook this attack button with our attack animation. 08:58.150 --> 08:59.790 So let's get out of play mode. 09:00.110 --> 09:07.510 And for that we're gonna move over to our skip and let's move over to our play attack animation function 09:07.510 --> 09:08.510 where we made it. 09:08.510 --> 09:14.910 So right over here, as you can notice, we just, uh, we just, uh, made this function. 09:14.910 --> 09:21.190 And this function is responsible for playing our animation clip, as you can notice, which is attack 09:21.190 --> 09:23.320 one, attack two, and attack three. 09:23.560 --> 09:30.680 So we need to call this function through our attack button so we can see we just this function is marked 09:30.680 --> 09:31.800 as private. 09:31.800 --> 09:35.240 So what we want to do, we're going to make this function public. 09:35.240 --> 09:38.320 So we can call the function uh through our button. 09:38.320 --> 09:40.760 So let's mark this function as public. 09:40.920 --> 09:44.040 And now we're going to press down Ctrl s to save our script. 09:44.040 --> 09:45.920 And now let's move over to unity. 09:46.280 --> 09:52.880 And we're going to hook that play attack animation function basically that function with our attack 09:52.880 --> 09:53.320 button. 09:53.320 --> 09:55.480 So just let's have a look on that. 09:55.960 --> 10:00.600 So we're going to so we need to hook that function with our attack button. 10:00.960 --> 10:02.640 So just wait a little moment. 10:02.640 --> 10:07.480 And once we are done we can just hook that function with our attack button. 10:07.800 --> 10:10.400 So for that we're going to head over to hierarchy. 10:10.520 --> 10:14.160 Let's go to canvas UI and let's choose this attack button. 10:14.160 --> 10:15.560 Let's go over to Inspector. 10:15.560 --> 10:17.520 Scroll down to the button component. 10:17.520 --> 10:20.400 And we can notice on click and it's empty. 10:20.400 --> 10:22.320 So let's click on this plus icon. 10:22.320 --> 10:27.640 And we do know that we need to track the game object and which game object the script is sitting on. 10:27.640 --> 10:29.280 So in our case player. 10:29.280 --> 10:30.360 So let's select that. 10:30.360 --> 10:33.360 Let's drag it there and it says no function. 10:33.360 --> 10:37.320 So let's click there and we will move over to player script in the bottom. 10:37.320 --> 10:39.840 As you can see our player C class. 10:40.000 --> 10:46.120 And in there we created play attack animation function as you can notice right over here. 10:46.120 --> 10:47.400 So we're gonna choose that. 10:47.400 --> 10:54.360 And now as soon as we click on this button it's going to play our attack animation clip of this player 10:54.360 --> 10:55.160 game object. 10:55.160 --> 10:56.560 So let's check that out. 10:56.560 --> 11:00.920 So I'm going to click on this play button in the top in order to play our game. 11:00.920 --> 11:02.960 And let's take a look on this. 11:04.400 --> 11:12.400 So you're gonna see that as soon as we click on this attack button it's going to play our attack animation. 11:12.400 --> 11:17.960 So if I just click on this attack button, as you can see by now, we can notice that we're playing 11:18.000 --> 11:19.640 our attack animation. 11:19.640 --> 11:26.170 But if I click left mouse button we're not playing our, uh, attack animation at all since basins. 11:26.170 --> 11:33.130 We just, uh, we just comment that function once we click the left mouse button, which is, uh, that's 11:33.130 --> 11:34.770 why it's not interrupting. 11:34.770 --> 11:40.090 Basically not displaying our attack animation once we click our left mouse button. 11:40.090 --> 11:45.170 But once we click on this attack button, we can notice it's playing the attack animation. 11:45.170 --> 11:47.410 Basically, it's working fine. 11:47.530 --> 11:52.010 And we can just click on this right or left arrow to move left and right. 11:52.010 --> 11:56.130 And we can just click on this jump button to jump as you can notice. 11:56.130 --> 11:58.210 So basically it's working fine. 11:58.490 --> 12:00.450 And I hope you get the idea. 12:00.450 --> 12:05.610 And I'm gonna get out of play mode and make sure you just move over to your UI game object. 12:05.610 --> 12:11.850 Basically the parent one, if you turn it into a prefab then go over to Inspector Overrides and then 12:11.850 --> 12:12.770 apply all. 12:12.770 --> 12:19.130 So the changes you made inside this attack and this jump button is going to be saved into this UI GameObject 12:19.130 --> 12:20.890 prefab as well. 12:20.890 --> 12:28.650 So I hope you get the idea that how you can hook a function with a button with a button to do a specific 12:28.690 --> 12:29.330 things.
