WEBVTT 00:00.120 --> 00:03.440 Let's add up the acceleration to our player game object. 00:03.440 --> 00:08.400 So over over time we just want this player game object to increase speed. 00:08.560 --> 00:09.720 So let's do that. 00:09.720 --> 00:12.480 So we're going to select our player GameObject in the hierarchy. 00:12.480 --> 00:16.400 And let's open up the player script in Inspector by double clicking on it. 00:16.600 --> 00:20.440 And let's uh what we're going to do we're going to add top of this bit. 00:20.440 --> 00:28.000 So as you can speed by default uh, by we set underneath our player skip which is 4.2 as you can see. 00:28.000 --> 00:32.200 So over time we just want to speed up our player game object. 00:32.200 --> 00:35.960 So we're just going to add top of this speed parameter some value. 00:35.960 --> 00:39.680 So over time just we can increase our speed. 00:39.680 --> 00:40.720 So let's do that. 00:40.720 --> 00:42.200 So we're going to move over to script. 00:42.200 --> 00:44.720 And we're going to make a another variable. 00:44.920 --> 00:47.080 And we're going to make that one as well public. 00:47.080 --> 00:50.080 So we can adjust through inspector as well. 00:50.320 --> 00:52.000 And that will be float. 00:52.000 --> 00:55.400 And we can call this parameter to something like acceleration. 00:55.400 --> 00:57.080 So this will be acceleration. 00:57.080 --> 00:59.680 So I'm going to call it acceleration. 00:59.680 --> 01:05.150 Elevation and by default, if you just want to give a default value, then you can just set equal to 01:05.310 --> 01:07.950 any value you would like to go with. 01:07.990 --> 01:12.390 But I'm gonna give something like, uh, a 0.1, something like that. 01:12.590 --> 01:17.590 And if and close that up with semicolon and what we're gonna do now. 01:17.710 --> 01:22.950 So before we move our, uh, player game object, we're just gonna add top of this speech. 01:22.950 --> 01:24.750 So we're going to type this speech. 01:24.750 --> 01:26.190 So this is our speech. 01:26.230 --> 01:30.310 And top of this speech we're just gonna add up this acceleration. 01:30.310 --> 01:32.310 So we're gonna use this plus equals. 01:32.310 --> 01:38.150 So you need to use this plus equal in order to add top of this speed parameter some unit. 01:38.150 --> 01:40.670 And we're going to add this acceleration. 01:40.670 --> 01:43.390 So we're going to type over here acceleration. 01:43.670 --> 01:46.470 And let's close that up with semicolon. 01:46.670 --> 01:52.710 And to make this number constant what we need to do we need to multiply with time.deltatime as we have 01:52.710 --> 01:55.110 done over here as you can see. 01:55.110 --> 01:58.070 So we're going to multiply this acceleration with our What time? 01:58.110 --> 02:02.550 Total time to make our acceleration constant over time. 02:02.550 --> 02:04.550 So we're going to multiply with time. 02:05.070 --> 02:07.270 Time dot delta time. 02:07.270 --> 02:08.230 And that's it. 02:08.230 --> 02:09.790 So speed uh speed. 02:09.830 --> 02:14.310 We set underneath our player script which is 4.2 as you can see. 02:14.350 --> 02:15.110 And top of that. 02:15.110 --> 02:16.830 So this one is 4.2. 02:16.830 --> 02:20.670 And top of that we're just adding the acceleration and acceleration. 02:20.670 --> 02:22.470 By default we set 0.1. 02:22.470 --> 02:25.270 So 4.2 plus 0.1. 02:25.270 --> 02:29.830 So over time and we do know this update function just going to run every single frame. 02:29.830 --> 02:35.310 So every single frame we just adding top of this speed this acceleration as you can see. 02:35.430 --> 02:41.990 So basically this is the thing in order to uh in order to increase our speed and we're going to remove 02:41.990 --> 02:43.390 this comment. 02:43.390 --> 02:48.070 We don't need double forward slash basically means comment and you can just remove that. 02:48.070 --> 02:51.510 And it's not going to interrupt our code anyways. 02:51.510 --> 02:54.670 So we can just remove that or we can just leave it like that. 02:54.710 --> 02:57.310 It's not gonna interrupt our code. 02:58.380 --> 03:01.700 and we're going to press down control S in order to save our skip. 03:01.700 --> 03:04.100 And let's move over to unity by now. 03:04.300 --> 03:07.500 So over time we're going to able to see this speed parameter. 03:07.540 --> 03:11.740 Just going to just going to increase over time. 03:11.740 --> 03:14.180 So just let's have a look on this. 03:14.380 --> 03:18.380 So just wait for a little moment and you're gonna able to see that. 03:18.780 --> 03:22.020 So by default we set the acceleration point one. 03:22.020 --> 03:25.700 But you can go with any number you would like to go with. 03:25.860 --> 03:28.100 But I'm gonna leave with a 0.1. 03:28.100 --> 03:34.300 As you can see, as soon as the script just gets compiled we can see our underneath player skip acceleration. 03:34.300 --> 03:36.260 By default we set 0.1. 03:36.420 --> 03:40.100 So let's click on this play button in the top in order to play our game. 03:40.100 --> 03:42.140 And let's have a look on this. 03:42.140 --> 03:45.900 So over time this speed right over here is just gonna increase. 03:45.900 --> 03:47.220 And you will see that. 03:47.660 --> 03:52.140 So just wait for a little moment in order to, uh, start our game. 03:52.140 --> 03:56.780 And we can see underneath our player skip in Inspector Speed just getting increased. 03:56.780 --> 04:00.820 So I'm going to click on this pause button in the top in order to pause my game. 04:00.940 --> 04:03.180 And now if we move over to player skip. 04:03.180 --> 04:05.900 As you can see speed by now is five. 04:05.900 --> 04:13.300 So over time the speed just increasing and increasing by this amount acceleration as you can see. 04:13.460 --> 04:14.860 So I'm going to get out of play mode. 04:14.860 --> 04:18.940 So just click on this play button in the top in order to get out of play mode. 04:19.180 --> 04:21.620 And now we're going to make our player jump. 04:21.620 --> 04:22.860 So let's do that. 04:22.860 --> 04:26.260 So we're going to select our player game object first in the hierarchy. 04:26.260 --> 04:29.340 And let's open up the player skip by double clicking on it. 04:29.700 --> 04:35.660 So what we're going to do now we're gonna uh so what we basically want to do if we press down space 04:35.700 --> 04:41.700 key on our keyboard, then we just want this player game object to jump in the y axis. 04:41.700 --> 04:43.580 So when we press down space key. 04:43.620 --> 04:46.300 But you can check for any key that you like. 04:46.300 --> 04:48.420 So we're going to use if statement. 04:48.420 --> 04:49.940 So let's move over to Skip. 04:49.940 --> 04:52.820 And we're going to do it over here in update function. 04:52.820 --> 04:57.730 Because every single frame we need to check if we press down space key or not. 04:57.850 --> 05:00.890 So that's why we're going to do inside this update function. 05:01.050 --> 05:04.330 So we're going to do some more over here in this update function. 05:04.330 --> 05:06.370 And we're going to use this if condition. 05:06.370 --> 05:10.250 So type this if and make first bracket and some curly brackets. 05:10.250 --> 05:16.890 And you need to put a condition in this first bracket condition that you want to check for. 05:17.090 --> 05:22.530 So in this if condition in this brackets we need to pass a condition which should be totally true. 05:22.530 --> 05:26.250 Something like we can simply say five is greater than one. 05:26.250 --> 05:26.850 Is it true? 05:26.890 --> 05:27.250 Yes. 05:27.250 --> 05:33.290 The condition we put in between this bracket and between this bracket is totally true. 05:33.290 --> 05:38.570 So whatever we're going to write in between these curly brackets by now, it will be executed. 05:38.730 --> 05:41.890 So let's suppose we just want to print out a message. 05:41.890 --> 05:44.770 Something like we're going to say five is greater than one. 05:44.770 --> 05:46.610 So let's print out a message. 05:46.610 --> 05:52.370 And we do know that in order to print out a message we're going to type this debug dot log function. 05:52.370 --> 05:55.400 So let's type debug dot log and make first bracket. 05:55.400 --> 05:59.480 Then close that up with semicolon and you need to pass a string. 05:59.480 --> 06:01.800 So make sure you do in this quotation. 06:01.800 --> 06:07.040 So type the quotation and you can pass the message you just want to see in your console tab. 06:07.040 --> 06:17.240 So I'm going to say something like this condition this condition is totally true totally true true. 06:17.280 --> 06:19.360 And make sure you just close that up. 06:19.360 --> 06:20.200 Semicolon. 06:20.200 --> 06:26.040 So we put a condition in this a condition as you can see five is greater than one. 06:26.040 --> 06:30.320 So the condition over here we put in this first bracket is totally true. 06:30.320 --> 06:34.720 So whatever we're gonna do inside this curly bracket is just gonna execute. 06:34.720 --> 06:40.920 So this line, uh, so this over here, this message just should be pop up in our console tab. 06:40.920 --> 06:41.160 Why? 06:41.200 --> 06:45.200 Because the condition we put in this, if it's totally true. 06:45.200 --> 06:46.000 So that's why. 06:46.040 --> 06:48.800 So we're going to press down Ctrl s to save our script. 06:48.800 --> 06:50.800 Now let's move over to unity. 06:50.960 --> 06:51.960 So we will see. 06:52.080 --> 06:57.480 So whenever we're going to click on this play button at the top to play our game, we will see as soon 06:57.480 --> 07:01.520 as the game's gonna start, that message is going to pop up in the console. 07:01.520 --> 07:05.440 Says, this condition is totally true, so just wait for it to compile. 07:05.600 --> 07:10.880 And now if I select the console tab from here, and let's click on this play button in the top to play 07:10.920 --> 07:11.720 our game. 07:11.720 --> 07:13.640 And let's have a look on this. 07:13.640 --> 07:15.880 So the message should pop up right away. 07:15.920 --> 07:18.280 Says this condition is totally true. 07:19.480 --> 07:20.440 So just wait. 07:21.400 --> 07:26.640 And as soon as the game started we can see the message just getting pop up in the console says, this 07:26.640 --> 07:29.800 condition is totally true, so I'm gonna get out of play mode. 07:29.800 --> 07:30.880 So why this message? 07:30.880 --> 07:32.680 Just getting pop up every single frame? 07:32.680 --> 07:38.600 Because we're doing inside update function and we do not update function runs every single frame. 07:38.600 --> 07:45.200 So every single frame, uh, this line of code just getting executed basically means this message just 07:45.200 --> 07:50.480 getting pop up in the console every single frame because we're doing a update function, as you can 07:50.480 --> 07:50.840 see. 07:51.080 --> 07:57.710 So instead of checking like this and let's suppose you put something like one is L, one is greater 07:57.710 --> 08:00.310 than five is this condition is true. 08:00.350 --> 08:02.950 No, this condition is totally false. 08:02.950 --> 08:09.430 So that's why in between these curly brackets, by now, you're gonna put it not gonna be executed at 08:09.430 --> 08:14.430 all because you put in this the condition, which is totally false. 08:14.430 --> 08:17.550 So we need to put a condition which should be totally true. 08:17.550 --> 08:20.430 So what we're gonna do, we're gonna check for some input. 08:20.430 --> 08:26.350 So we need to use this input dot, get, uh, key function and then make this first bracket. 08:26.350 --> 08:30.710 And this bracket you need to pass the key code you just want to check for. 08:30.750 --> 08:32.270 I'm going to check for space key. 08:32.310 --> 08:36.830 And basically once I press down space key I want this player game object to jump. 08:36.830 --> 08:38.310 So I'm going to check for space key. 08:38.310 --> 08:39.990 So let's go to that line of code. 08:39.990 --> 08:44.870 So we're using this input dot get key function in order to check for input. 08:44.870 --> 08:53.100 So you need to put in this brackets a the key a which uh With which key you just want to check for. 08:53.100 --> 08:55.100 So I'm going to check for my space key. 08:55.180 --> 08:58.860 So I'm going to pass Keycode key code dot space. 08:59.100 --> 09:00.380 Key code dot space. 09:00.620 --> 09:03.700 It basically means we just pressing down space key. 09:03.740 --> 09:09.780 So if input dot get key key code dot space basically means if we press down space key then this line 09:09.820 --> 09:11.380 of code just going to be execute. 09:11.460 --> 09:13.860 You can check for any key that you like. 09:13.860 --> 09:16.620 So you can check for this a as well as. 09:16.620 --> 09:22.180 So it's going to check for if you press down a key then what's a whatever you're gonna do inside this 09:22.180 --> 09:23.060 curly bracket. 09:23.100 --> 09:24.460 It's just gonna execute. 09:24.460 --> 09:26.300 So I'm going to check for my space key. 09:26.300 --> 09:29.820 So that's why I'm going to pass a key code dot space. 09:30.060 --> 09:34.300 And what I'm gonna do now I'm going to make a function in order to jump. 09:34.300 --> 09:36.420 So I'm going to make it somewhere over here. 09:36.580 --> 09:40.740 And for function what we basically need to do, we need to type this void. 09:40.940 --> 09:44.580 And we have to name the function what we want to name it. 09:44.580 --> 09:46.540 So I'm going to call it something like jump. 09:46.540 --> 09:51.860 And then you need to make this first bracket and some curly brackets in order to make the function. 09:52.060 --> 09:56.940 So for function you need to type void and you have to name the function what you want to name it, and 09:56.940 --> 10:00.220 make sure you just make this first bracket and some curly brackets. 10:00.260 --> 10:04.660 And let's suppose you just didn't assign it to something like public or private. 10:04.660 --> 10:08.940 So this function automatically by default it's going to be a private function. 10:09.140 --> 10:11.860 And let's suppose you just put public. 10:11.860 --> 10:14.820 So it's gonna be public function. 10:14.820 --> 10:18.140 Or you can just make this one as well private. 10:18.500 --> 10:25.020 And and if you just remove this private or public it's gonna be automatically by default gonna assign 10:25.060 --> 10:26.860 a as a private function. 10:26.860 --> 10:32.980 And now what we, I want to do in this function or inside this curly brackets, I just want to print 10:32.980 --> 10:34.460 out a message for now. 10:34.460 --> 10:40.220 So I'm going to type Debug.log in order to print out a message and make first bracket. 10:40.220 --> 10:41.980 Then close that up with semicolon. 10:41.980 --> 10:46.700 And you need to put a string that you just want to see in your console tab. 10:46.700 --> 10:50.770 So I'm going to say something like player jump, player jump. 10:51.810 --> 10:56.210 And right now what I'm going to do I'm going to remove this message. 10:56.330 --> 10:58.410 Message from this if condition. 10:58.410 --> 11:01.370 And what I'm going to do I'm going to call this jump function. 11:01.370 --> 11:02.690 So we just made the function. 11:02.690 --> 11:07.010 We also need to call this function in order to execute this line of code. 11:07.010 --> 11:09.730 So we're going to call the function inside this package. 11:09.730 --> 11:13.490 So we're going to call the function over here which is in our case jump. 11:13.530 --> 11:17.450 And you need to make this first bracket and then close that up with semicolon. 11:17.450 --> 11:21.170 So let me explain what we basically doing right here here. 11:21.330 --> 11:24.370 So we're just using this if condition in order to check. 11:24.370 --> 11:30.410 And we're checking if input dot get Kiki code dot space basically means if we press down space key on 11:30.410 --> 11:36.450 our keyboard, then what we do is we're just calling this jump function and jump what we have done inside 11:36.450 --> 11:42.290 this jump function, we just printing out a message in the console says player jump as you can see. 11:42.290 --> 11:48.570 So as soon as we're gonna press down space key on our keyboard, this jump function And this jump function 11:48.570 --> 11:53.490 over here we can see is just printing out a message in the console says player jump. 11:53.530 --> 11:54.730 As you can see. 11:54.730 --> 11:58.210 So we're going to press down control S in order to save our skip. 11:58.210 --> 12:00.130 And now let's move over to unity. 12:00.690 --> 12:05.970 So whenever we're going to press down Space key on our keyboard, you will see that message is going 12:05.970 --> 12:08.490 to pop up in the console says Player Jump. 12:08.770 --> 12:11.130 So we're calling that function jump function. 12:11.130 --> 12:14.130 And we do know what we're doing inside that function. 12:14.130 --> 12:20.610 We just simply, uh, just, uh, simply just printing out the message in the console says player jump. 12:20.610 --> 12:21.370 So let's have a look. 12:21.370 --> 12:24.770 So I'm going to click on this play button in the top to play our game. 12:25.010 --> 12:31.370 And once I press down space key on my keyboard that message is just going to pop up right away. 12:31.370 --> 12:32.650 So just wait for it to compile. 12:32.690 --> 12:34.730 I'm really sorry for the noises. 12:35.010 --> 12:40.690 So if I press the space key, as you can see, as soon as I press down space key in the console tab, 12:40.690 --> 12:44.290 we can see a message just getting pop up, says Player Jump. 12:44.290 --> 12:48.920 So instead of printing out what we just wanted to, we just want to make clear jump. 12:48.920 --> 12:54.000 So let's get out of play mode, and let's double click on that message in order to move that line of 12:54.000 --> 12:54.400 code. 12:54.760 --> 12:59.920 And instead of printing out message what we want, we just want to make our player jump. 12:59.920 --> 13:02.360 So before we make our player jump. 13:02.360 --> 13:07.640 So if we head over to unity and then select this player game object in the hierarchy and press down 13:07.680 --> 13:10.400 F in order to focus on that game object. 13:10.400 --> 13:16.000 What we need we need a reference of this rigidbody 2D component of this player game object. 13:16.040 --> 13:17.800 Then we can make our player jump. 13:17.800 --> 13:22.480 So basically what we need if we select our player game object then go over to Inspector. 13:22.520 --> 13:27.480 We can see we just added up a rigid body 2D component to this player game object. 13:27.480 --> 13:35.000 And this rigid body 2D component is responsible for velocity, adding force, and lots of other things. 13:35.000 --> 13:39.560 So we need a reference or we need a link of this rigid body. 13:39.560 --> 13:41.880 Then we can make our player jump. 13:41.880 --> 13:47.510 So what we need we need to grab the reference of this rigid body of this player game object in order 13:47.510 --> 13:49.150 to make our player jump. 13:49.230 --> 13:53.670 So let's move over to our code and let's go to top of our class. 13:53.670 --> 13:58.710 And we're going to make it public so we can see underneath our player skip basically over here. 13:58.910 --> 14:02.150 And the component we're looking for is a rigid body 2D. 14:02.150 --> 14:05.110 So you need to type the component that you're looking for. 14:05.110 --> 14:07.190 So in our case rigidbody 2D. 14:07.190 --> 14:08.990 So we're going to type rigidbody 2D. 14:09.230 --> 14:12.110 And we have to name the component what we want to name it. 14:12.110 --> 14:18.230 So I'm going to call it something like RB and then close that up semicolon RB short for basically rigidbody 14:18.270 --> 14:18.710 2D. 14:18.870 --> 14:21.630 So we just made a variable rigid body type. 14:21.790 --> 14:27.550 So so we're going to able to see this slot or this parameter underneath our player. 14:27.950 --> 14:30.670 So we're going to press down Ctrl S to save our script. 14:30.670 --> 14:32.390 And let's move over to unity. 14:33.950 --> 14:38.630 So underneath our player we're going to able to see that rigid body slot. 14:38.670 --> 14:44.070 So what we have to do we need to drag this rigid body component into that slot. 14:45.590 --> 14:52.430 As soon as this player skip gets compiled, we can see underneath our player skip, a slot just pops 14:52.430 --> 14:54.950 up and it says none Rigidbody 2D. 14:54.950 --> 14:56.790 Basically, it means empty. 14:56.910 --> 15:01.630 So what we need to do now, we need to select this rigidbody from this player game object. 15:01.630 --> 15:04.630 So make sure you select the player GameObject first in the hierarchy. 15:04.630 --> 15:06.350 Then move over to Inspector. 15:06.350 --> 15:12.070 And we're going to take this rigid body of this player game object and drag it into that slot. 15:12.150 --> 15:15.670 And now we can see we have player rigid body reference. 15:15.670 --> 15:20.350 As you can see means we have the reference of this rigid body 2D component. 15:20.350 --> 15:23.390 And now we are able to make our player jump. 15:23.390 --> 15:26.470 So let's open up our player script by double clicking on it. 15:26.470 --> 15:29.110 And let's move over to this jump function. 15:29.110 --> 15:30.670 So we're going to remove this message. 15:30.670 --> 15:34.550 Instead of printing out message we just want to make our player jump. 15:34.550 --> 15:35.430 So what are we going to do. 15:35.430 --> 15:37.030 We're going to go over to RV. 15:37.230 --> 15:39.710 Simply we're just moving over to rigid body. 15:39.710 --> 15:45.860 And then use this dot add at first function in order to add the force and then make this first bracket. 15:45.900 --> 15:48.060 So this rb dot add force function. 15:48.060 --> 15:51.980 It's going to take the direction in which direction you just make one. 15:52.020 --> 15:53.740 You just want to make the jump. 15:53.860 --> 15:57.740 So we just want this player game object to jump in the y axis. 15:58.140 --> 16:03.260 So if we select our player GameObject in the hierarchy and then move tool, we don't want this player 16:03.300 --> 16:05.300 game object to jump in the x axis. 16:05.300 --> 16:06.420 Something like this. 16:06.460 --> 16:09.900 We want this player game object to jump in the y axis. 16:09.900 --> 16:15.380 So we're going to use a vector tool because that vector two is just going to have x axis and the y axis. 16:15.380 --> 16:22.140 So we can just set y or x according to what we really need to do. 16:22.140 --> 16:23.380 So let's go to that. 16:23.460 --> 16:24.940 Uh let's go to script. 16:24.940 --> 16:29.540 And we're going to use this new vector tool and sorry new vector two. 16:29.580 --> 16:32.940 And we do know uh, so make some uh first bracket. 16:32.940 --> 16:36.980 And this vector two is just going to have x axis and the y axis. 16:36.980 --> 16:40.890 So we don't want to make our player jump in the x axis. 16:40.890 --> 16:45.130 So that's why in the x axis we're going to put zero f and in the y. 16:45.170 --> 16:49.530 We just want to make our player jump some units something like 5 or 7. 16:49.530 --> 16:53.130 So let's make another variable for our player jump. 16:53.130 --> 16:56.410 So let's go to the script and let's go to the top of our class. 16:56.410 --> 16:58.370 And we're going to make another variable. 16:58.370 --> 17:02.690 So let's make this one public so we can adjust underneath our player skip. 17:02.810 --> 17:04.130 And that will be float. 17:04.130 --> 17:06.530 And we can call this one something like jump height. 17:06.530 --> 17:08.850 So let's call it jump height. 17:09.010 --> 17:11.570 And by default you can give any value you like. 17:11.570 --> 17:13.770 So I'm going to give something like seven. 17:14.090 --> 17:16.170 And let's close that off with semicolon. 17:16.170 --> 17:22.170 And if you just want to do just want to close that off something like this, then you can adjust underneath 17:22.170 --> 17:24.090 your player skip as well. 17:24.090 --> 17:25.770 But I'm gonna give a default value. 17:25.770 --> 17:28.290 So that's why I'm going to set equal to seven. 17:28.810 --> 17:33.290 And now what I'm going to do in the Y I'm going to pass this jump height and the jump height. 17:33.290 --> 17:36.290 By default we set seven as you can see. 17:36.290 --> 17:43.210 So this just gonna be seven means our player GameObject will jump in the Y axis with seven unit, something 17:43.210 --> 17:43.850 like this. 17:44.050 --> 17:47.490 So this rb dot add force function is. 17:47.650 --> 17:49.130 It's basically a force. 17:49.130 --> 17:50.530 So that's why as a comma. 17:50.530 --> 17:53.290 So you need to put this comma as a second argument. 17:53.290 --> 17:56.170 You need to pass this force mode to d dot impulse. 17:56.210 --> 17:56.610 Why. 17:56.730 --> 17:58.530 Because this is a force. 17:58.530 --> 18:03.330 So that's why as a comma you need to pass the force mode to d dot impulse. 18:03.330 --> 18:06.130 So firstly we just pass the direction. 18:06.130 --> 18:08.450 And the second thing we need to pass the force mode. 18:08.450 --> 18:13.450 So we're going to type force mode 2D dot impulse and then close that up with semicolon. 18:13.450 --> 18:16.850 And we're going to press down Ctrl s in order to save our code. 18:16.850 --> 18:20.530 So let me explain one more time what we basically doing. 18:20.970 --> 18:22.610 So let me explain that. 18:23.810 --> 18:25.250 So just wait for to compile. 18:25.250 --> 18:28.970 And once our script gets compiled we are ready to do that. 18:28.970 --> 18:34.730 So what we're doing firstly we're just going over to this RB basically means we have the reference means 18:34.730 --> 18:41.000 we just moving over to this player game object this is rigid body 2D, and we're using our force function 18:41.000 --> 18:42.720 in order to add the force. 18:42.720 --> 18:45.040 And we do know it's going to take the direction. 18:45.040 --> 18:48.240 So in the Y we set jump height as you can see. 18:48.400 --> 18:53.600 And in the x we set zero basically means we don't want to jump in the x axis. 18:53.640 --> 18:56.040 We only want to jump in the y axis. 18:56.040 --> 18:57.960 So that's why we set a. 18:58.000 --> 19:01.240 We just replace that y with some height and jump height. 19:01.280 --> 19:06.240 By default we set seven and we can see as well underneath our player skip. 19:06.240 --> 19:08.800 And we can adjust it over here as well. 19:08.800 --> 19:11.240 So that's why we just made that field public. 19:11.280 --> 19:15.160 And make sure you just press down Ctrl s in order to save your skip. 19:15.160 --> 19:17.160 And now let's move over to unity. 19:17.280 --> 19:21.360 And let's click on this play button in the top in order to play our game. 19:21.360 --> 19:22.480 And let's have a look. 19:22.480 --> 19:26.640 So whenever we're going to press down space key that jump function just gonna call. 19:26.640 --> 19:29.360 And we do know what we're doing inside that jump function. 19:29.360 --> 19:31.040 We just making our player jump. 19:31.040 --> 19:33.880 So if I just press down space key as you can see. 19:33.880 --> 19:35.480 So I'm gonna get out of play mode. 19:35.520 --> 19:40.360 I just want to make the player speed a little bit low so we can just test the jump. 19:40.360 --> 19:45.080 So I'm going to make this speed parameter underneath my player skip something like one. 19:45.080 --> 19:49.520 And now let's click on this play button in the top in order to check that jump. 19:50.160 --> 19:54.040 And you can adjust the jump height as well underneath your player skip. 19:54.080 --> 19:55.840 It's totally up to you. 19:56.960 --> 20:03.080 So now if I press down space key on my keyboard, as you can see, as soon as we press down Space Key, 20:03.120 --> 20:07.960 we are able to see this player game object just jumping in the y axis. 20:08.400 --> 20:10.720 And and that is cool thing. 20:10.720 --> 20:11.960 I hope you get the idea. 20:11.960 --> 20:18.240 So I'm gonna get out of play mode and make sure you just press down Ctrl s in order to save your project. 20:18.240 --> 20:21.760 And also make sure you select your player game object in the hierarchy. 20:21.800 --> 20:25.920 Then go over to Inspector, then overrides and then click on this Apply all. 20:25.960 --> 20:30.400 If you made your player game object a prefab, so make sure you just do that. 20:30.440 --> 20:36.560 Or you can just skip this part as well if you haven't made this player game object prefab.
