WEBVTT 00:00.040 --> 00:06.240 Our player is not flipping to the left direction once it starts moving to the left direction, so we 00:06.240 --> 00:07.120 need to flip that. 00:07.120 --> 00:08.760 But before we we do. 00:08.800 --> 00:09.680 Let me show you. 00:09.840 --> 00:16.040 So I'm going to click, uh click on this play button in the top in order to start our game. 00:16.040 --> 00:17.880 And let's have a look on this. 00:19.080 --> 00:24.240 So we should able to see that we're not gonna flip to the left direction. 00:24.240 --> 00:25.760 So we need to flip that. 00:26.000 --> 00:27.480 So let me show you first. 00:27.680 --> 00:33.840 So as you can see we are moving to the left direction, but we're not flipping at all to the left direction. 00:34.040 --> 00:41.160 So if I select my player in the hierarchy then move over to Inspector Transform component and then rotation 00:41.160 --> 00:43.040 and go with y axis. 00:43.040 --> 00:46.400 And if I put in the y something like -180. 00:46.600 --> 00:52.080 As you can see, as soon as we put -180 it's flipped to the left direction. 00:52.080 --> 00:58.800 So basically what we have to do, we need to set the Euler angles in the y to -180 as you can see. 00:59.080 --> 01:00.720 So let's get out of play mode. 01:01.000 --> 01:03.380 And for that we will create a variable. 01:03.380 --> 01:06.460 We're just going to keep track of which direction we're looking. 01:06.580 --> 01:09.900 So let's open up our player script by double clicking on it. 01:10.260 --> 01:13.100 And let's go to the top of our class. 01:13.260 --> 01:14.700 Somewhere around here. 01:14.980 --> 01:20.220 And that parameter doesn't need to be public so we can make it private instead. 01:20.340 --> 01:23.620 So this will be private private. 01:23.620 --> 01:26.580 And this will be bool which can be true or false. 01:26.700 --> 01:29.260 And let's call this one facing right. 01:29.500 --> 01:30.940 Facing right. 01:30.940 --> 01:33.220 And let's close that up with semicolon. 01:33.220 --> 01:35.740 And we will move over to this start function. 01:35.740 --> 01:39.380 So we do know that start function get call in this start of the game. 01:39.380 --> 01:42.860 So in this start of the game I'm going to say facing right to true. 01:43.100 --> 01:45.140 And let's close that up with semicolon. 01:45.140 --> 01:50.180 So let me explain why we created this parameter and why we set it equal to true. 01:50.620 --> 01:55.260 So this parameter we just created to keep track of which direction we're looking. 01:55.260 --> 01:57.340 So we're looking to the right direction. 01:57.340 --> 02:01.420 So that's why I just named that parameter to something like facing right. 02:01.420 --> 02:04.340 And in the start of the game I just said facing right. 02:04.440 --> 02:05.440 equal to true. 02:05.440 --> 02:08.240 As you can see, we're looking to the right direction. 02:08.240 --> 02:13.920 So that's why uh, so that's why in the start of the game we just said facing right. 02:13.960 --> 02:14.480 True. 02:14.480 --> 02:19.160 But once we're gonna start moving to the left direction, we need to flip this player. 02:19.320 --> 02:22.760 Uh, so what we have to do, we're going to make a function for it. 02:22.760 --> 02:27.880 So let's go to our script and let's make the function somewhere around here. 02:28.240 --> 02:30.800 And for function we're going to type void. 02:31.000 --> 02:33.440 And let's call this function to something like flip. 02:33.440 --> 02:36.400 Let's make first bracket and some curly brackets. 02:36.400 --> 02:38.360 And what we want to check over here. 02:38.400 --> 02:42.640 We basically want to check if we're moving to the left direction or not. 02:42.640 --> 02:48.880 And we do know that that movement parameter right over here, as you can see, we created to just, 02:48.920 --> 02:51.280 uh, which direction we're going. 02:51.560 --> 02:54.600 Uh, this right over here is responsible. 02:54.920 --> 03:00.200 Uh, we do know that if the movement is something like minus one means we're holding down a key. 03:00.400 --> 03:03.520 So this player will start moving to the left direction. 03:03.520 --> 03:05.800 So that movement is just gonna be minus one. 03:05.800 --> 03:10.210 Basically means we're just gonna move or start moving to the left direction. 03:10.210 --> 03:13.290 So we need to flip our player to the left direction. 03:13.930 --> 03:17.450 So now what we're gonna do, we're gonna move over to this flip function. 03:17.450 --> 03:19.210 And over here we will check. 03:19.210 --> 03:23.770 So let's make if condition, let's make first bracket and some curly brackets. 03:23.770 --> 03:25.730 So what we want to check over here. 03:25.730 --> 03:30.490 We basically want to check if our movement is lesser than zero. 03:30.850 --> 03:37.050 And we do note that once we press down a key on our keyboard, that movement just gonna, just gonna 03:37.050 --> 03:37.970 be minus one. 03:37.970 --> 03:45.610 And we do know that if this if this movement is minus one and minus one is lesser than zero, it basically 03:45.610 --> 03:46.610 means true. 03:47.010 --> 03:50.290 Minus one means that we are moving to the left direction. 03:50.290 --> 03:52.610 So what we need to do, we need to flip. 03:52.770 --> 03:56.170 But we also want to check if we started moving to the left. 03:56.170 --> 03:59.410 Direction basically means that movement is minus one. 03:59.410 --> 04:02.450 And we do know that minus one is lesser than zero f. 04:02.490 --> 04:07.650 At the same time, if we are looking to the right direction, we started moving to the left direction, 04:07.650 --> 04:11.070 but we are looking to the right direction, then what we have to do? 04:11.070 --> 04:13.670 We need to flip this player to the left direction. 04:13.670 --> 04:15.390 So also we want to check. 04:15.390 --> 04:17.710 So we're going to use this an end condition. 04:17.710 --> 04:18.910 And we will check. 04:19.310 --> 04:25.670 We will check that if facing right is equals equals to true basically means we're looking to the right 04:25.710 --> 04:26.550 direction. 04:26.550 --> 04:27.990 So now what we have to do. 04:27.990 --> 04:29.510 We need to flip this player. 04:30.150 --> 04:34.750 So to in order to flip that we're going to move over to this rotation. 04:34.750 --> 04:37.590 Or you can simply say Euler angles in the y. 04:37.670 --> 04:40.630 We're going to set to something like -180. 04:40.670 --> 04:46.150 And we do know that once we set -180 this player flips to the left direction. 04:46.150 --> 04:48.310 So what we will do in this situation. 04:48.750 --> 04:50.790 So we will go to transform. 04:50.790 --> 04:57.390 Then we're going to access the Euler angles which going to have x x y and z axis. 04:57.510 --> 05:00.990 And we're going to set equal to a new Vector3 y. 05:00.990 --> 05:02.830 We set it equal to new Vector3. 05:02.870 --> 05:09.110 Since this transform dot Euler angles just going to have x axis, y axis, and the z axis. 05:09.270 --> 05:15.610 And this new Vector3 is also going to have the x axis, y axis, and the z axis. 05:15.610 --> 05:17.850 And let's close that off with semicolon. 05:18.130 --> 05:20.450 So we want to flip to the left direction. 05:20.450 --> 05:24.690 So in the y part we need to do we basically need to put minus one ATF. 05:24.730 --> 05:27.330 So we're going to put minus one ATF in the Y. 05:27.690 --> 05:31.210 And we're not going to do at all anything in the x axis. 05:31.210 --> 05:32.770 So we're going to put zero f. 05:32.770 --> 05:35.730 And we will do the same thing in the z axis. 05:35.970 --> 05:39.290 So once we flip our player to the left direction. 05:39.490 --> 05:45.770 Uh so if we flip to the left direction, as you can see it will no longer able to look to the right 05:45.770 --> 05:46.450 direction. 05:46.450 --> 05:50.770 So that's why after flipping we will set that facing right to false. 05:50.770 --> 05:55.290 Because in that moment we're not going to look towards to the right direction. 05:55.290 --> 05:56.130 So that's why. 05:56.410 --> 06:04.410 So after flipping so after flipping we're going to set facing right equal to false because we no longer 06:04.410 --> 06:06.890 able to look to the right direction. 06:07.050 --> 06:10.130 And now we're going to press down Ctrl S to save our script. 06:10.130 --> 06:12.010 And now let's move over to unity. 06:12.110 --> 06:15.950 Firstly, we're checking if movement is lesser than zero f or not. 06:15.990 --> 06:21.710 Means that if we started moving to the left direction or not at the same time we checking to the right. 06:22.110 --> 06:27.910 If we're looking to the right direction, then firstly moving over to this player transform, then Euler 06:27.910 --> 06:30.630 angles and we're setting y to -180. 06:30.670 --> 06:33.590 So it's just going to flip to the left direction. 06:33.590 --> 06:35.390 So let's have a look on this. 06:37.230 --> 06:39.510 But we're gonna get nothing. 06:39.550 --> 06:40.750 Let me show you why. 06:41.310 --> 06:44.030 So just wait a moment to compile our script. 06:44.030 --> 06:47.630 And once it's done, we can just check it right away. 06:47.870 --> 06:52.110 Once our compilation is done for our script. 06:53.110 --> 06:54.990 So just wait a little moment. 06:54.990 --> 07:02.510 And now if we go ahead and then click on this play button in the top, you will see nothing gonna happen. 07:02.510 --> 07:07.510 Even if we press down a key Y, because we also need to call that function. 07:07.510 --> 07:10.950 We basically made that flip function, but we never calling it. 07:10.950 --> 07:17.120 So if I press down a key, as you can see, it's not looking to the left direction because we also need 07:17.120 --> 07:18.560 to call the flip function. 07:18.560 --> 07:24.200 So let's get out of play mode and where we need to call it, we need to call it this update function. 07:24.200 --> 07:29.680 Because this update function runs every single frame and every single frame, we need to check which 07:29.680 --> 07:35.480 direction we going or, uh, which direction we simply moving on. 07:35.920 --> 07:37.920 So we're going to call it something over here. 07:37.920 --> 07:40.080 So let's call the flip function here. 07:40.080 --> 07:46.600 And then close that off with semicolon after setting up the movement right over here, as you can see. 07:46.640 --> 07:54.200 And if I save my script and then move over to unity, you will see that as soon as we gonna start moving 07:54.240 --> 07:59.400 to the left direction, we will see our player to flip to the left direction. 07:59.440 --> 08:05.760 Since we setting the Euler angles in the y to minus one 8180, let me show you. 08:05.760 --> 08:09.840 So let's click on this play button in the top in order to start our game. 08:09.880 --> 08:12.040 And let's, uh, check it. 08:15.520 --> 08:17.340 So just wait a moment. 08:17.740 --> 08:24.420 And now, if I hold down a key, as you can see, as soon as we press down a key, uh, this player 08:24.420 --> 08:26.420 just flips to the left direction. 08:26.580 --> 08:34.100 But if I, uh, right now start moving to the right direction, it's not, uh, flipping to the right 08:34.140 --> 08:36.900 direction at all after flipping to the left. 08:36.940 --> 08:43.300 So what we basically have to do if we select our player in the hierarchy, move over to Inspector transform 08:43.300 --> 08:46.820 and rotation in the Y or Euler angles in the y. 08:46.860 --> 08:51.860 If we set back to zero, as you can see, it's flipped to the right direction. 08:51.860 --> 08:56.300 So basically we need to check if we just moving to the right direction. 08:56.300 --> 08:59.820 Then we basically have to set back this y to zero. 08:59.820 --> 09:02.580 So it's going to flip to the right direction. 09:02.580 --> 09:07.020 And after flipping we also need to set that facing right parameter to true. 09:07.060 --> 09:07.460 Why? 09:07.580 --> 09:12.220 Because as you can see in this situation we're gonna look to the right direction. 09:12.220 --> 09:15.020 So that's why we need to set facing right to true. 09:15.020 --> 09:21.360 So let's get out of play mode and let's move over to script and let's move over to our flip function. 09:21.480 --> 09:29.240 So over here we will check else if else if our movement movement is greater than zero f. 09:29.360 --> 09:35.560 And we do know that if movement is greater than zero f basically means we holding down D means we started 09:35.560 --> 09:37.160 moving to the right direction. 09:37.400 --> 09:41.560 And also we will check if we're not looking to the right direction. 09:41.560 --> 09:45.360 Basically this player have just looking to the left direction. 09:45.360 --> 09:52.720 So also we will check if we started moving right direction and we not uh, looking to the right direction 09:52.720 --> 09:55.880 basically means facing right equals equals to false. 09:56.120 --> 10:02.360 If that is the case then what we're going to do, we're going to set back our Euler angles to Euler 10:02.360 --> 10:04.080 angles in y to zero. 10:04.080 --> 10:06.760 So I'm going to copy this line of code by Ctrl C. 10:06.960 --> 10:09.840 And let's paste it over here by Ctrl V. 10:10.320 --> 10:14.760 And so what we will do firstly we will go to transform then Euler angles. 10:14.920 --> 10:17.800 And in the y we're going to set back to zero f. 10:18.000 --> 10:20.900 And after flipping to the right direction. 10:20.940 --> 10:27.020 We need to set the spacing right parameter to true instead of false, because in that situation, we're 10:27.020 --> 10:28.620 going to look to the right direction. 10:28.620 --> 10:30.860 As you can notice right over here. 10:31.220 --> 10:32.580 So firstly what we're doing. 10:32.620 --> 10:36.100 Firstly we're checking if our movement is greater than zero. 10:36.380 --> 10:38.860 Basically means we're moving to the right direction. 10:39.100 --> 10:44.100 And we do know that if we hold down D key that movement just gonna be one. 10:44.100 --> 10:46.700 So one basically is greater than zero. 10:47.060 --> 10:48.460 And we don't know that. 10:48.460 --> 10:51.340 And also we're checking if facing right is false. 10:51.340 --> 10:54.540 Basically means this player is looking to the left direction. 10:54.540 --> 10:58.460 Then what we're doing we're just setting the Y to zero F. 10:58.460 --> 11:01.860 And after that we're just setting facing right parameter to true. 11:01.900 --> 11:06.660 Because in that in this situation, this player just gonna look to the right direction. 11:06.660 --> 11:09.740 So that's why we uh, we just set facing. 11:09.740 --> 11:10.180 Right. 11:10.180 --> 11:10.540 True. 11:10.780 --> 11:14.100 And if you just want to don't do it like this. 11:14.140 --> 11:20.420 If facing right and if, if you just put exclamation mark, it basically means the same thing. 11:20.500 --> 11:23.920 Facing right basically means facing right is false. 11:24.000 --> 11:25.600 It's basically the same thing. 11:25.640 --> 11:27.520 Or you can just simply do it. 11:27.560 --> 11:29.720 Equals equals to false. 11:29.920 --> 11:34.680 And if you just want to check with true you can just leave it like this. 11:34.720 --> 11:37.480 It's also basically means true true. 11:37.480 --> 11:43.400 And if you just put exclamation mark right in front of this, facing right basically means it false. 11:43.560 --> 11:50.000 So firstly we're checking if movement is greater than zero means we started moving to the right direction. 11:50.000 --> 11:53.880 And if we're looking to the left direction then firstly we flipping. 11:53.920 --> 11:57.800 And after flipping we just setting back facing right parameter to true. 11:57.840 --> 11:58.920 As you can see. 11:59.120 --> 12:05.880 So now if I press down Ctrl s to set my script and then move over to unity, you will able to notice 12:05.880 --> 12:11.800 that as soon as we're gonna start moving to the right direction, our player just gonna flip to the 12:11.800 --> 12:12.680 right direction. 12:12.720 --> 12:17.960 Since we setting Euler angles in the y to zero or back to zero. 12:18.120 --> 12:23.530 So now if we go ahead and then click on this play button in the top to play our game. 12:23.530 --> 12:25.090 We can check that out. 12:25.570 --> 12:27.930 Uh, firstly, let's start moving. 12:28.130 --> 12:28.770 Moving. 12:28.770 --> 12:33.010 Or let's begin with a key basically to the left direction. 12:33.010 --> 12:33.850 So if I move. 12:33.890 --> 12:36.890 As you can see, it's moving to the left direction. 12:36.890 --> 12:39.290 And player just flipped to the left direction. 12:39.410 --> 12:45.610 And now if I start moving to the right direction we can see player flips to the right direction. 12:45.850 --> 12:51.650 And if we start moving one more time again to the left direction, we can see it's flipping to the left 12:51.650 --> 12:55.970 direction and it's flipping to the right direction as well. 12:56.010 --> 12:59.970 Basically, this player is flipping in the direction it's going. 13:00.010 --> 13:02.610 So basically that is a pretty great thing. 13:02.770 --> 13:09.730 And let's suppose you still want to see this, uh, private, uh, this right over here, this private 13:09.730 --> 13:13.970 facing right parameter, uh, underneath your player script. 13:13.970 --> 13:19.650 Then how you can do it for, uh, to do it, just go over to Inspector in the top right you can see 13:19.690 --> 13:20.210 three dots. 13:20.210 --> 13:23.290 So just click there and then click on this debug mode. 13:23.290 --> 13:28.030 And as soon as we have chosen we can see our facing right parameter. 13:28.030 --> 13:30.670 But I'm gonna go back to my normal mode. 13:30.670 --> 13:36.190 So you can just click on that three dot once again in order to go back in normal mode. 13:36.190 --> 13:40.950 And I'm gonna get out of play mode by just clicking on that play button. 13:40.950 --> 13:46.910 So I hope you get the idea that how you can flip your player in the direction player is going. 13:46.910 --> 13:49.310 So I hope you get you get the idea. 13:49.310 --> 13:54.030 And also we need to make the idle animation clip and all of those things. 13:54.430 --> 13:59.550 And now I'm gonna press down Ctrl s on my keyboard in order to save my project. 13:59.710
