All language subtitles for 08. CharacterController & Jumping logics

Now let's implement jumping logics in our game.

There's two kinds of gravity systems we can implement.

Either we can have a constant gravity meaning that as you can see from the first picture the number

of frames of Maya reaching the highest point while jumping equals to the same amount of frames for Mario

falling to the ground in the second example you can see that the gravity is at a variable intensity.

So when Mario is jumping upwards the gravity is less intense than when Mario is falling.

Most Mario games use gravity at a variable intensity.

First let's implements the constant gravity system and then let's implement the variable intensity gravity

system let's head back to unity we select or player logic and first we need to implement the jump height

for this we will use zero point five f then we will also need to implement a variable for gravity let's

use this for now and we also need to add a boolean to track when we're jumping in the update function

we will check whether the player is jumping or not so we can say if the player is not jumping and input

get button down jump

then jump is true

and then in a fixed update willing to apply to gravity.

So what we can say is if the character is not on the ground.

So when he's in the air for this we can do character controller is grounded and in this case I say if

the character controller is not grounded then we are going to reduce the gravity from his movement.

Why else he if he is standing on the ground we're going to set movement y to zero and if the player

is jumping

First we will set the jumping to false and we will set his movement height to a specific value.

Equals to the jump height so all we're doing right now is here we are applying to gravity

and here we are.

Adding jump to movement y.

Setting setting jump height to movement height is better okay.

Let's try it isn't a game.

So now if your press play I move my character and I press base.

The character will jump if I want him to jump higher or lower I can simply tweak to values.

I just have to change my variables.

I can increase or decrease my jump pints and I can increase or decrease my gravity if I save and then

run it again.

You will see that the jumping results will be different.

Now he jumps slightly higher and falls a little bit faster.

Now as you can see the time it takes for the player to reach the top point in his jump is the same time

it takes for him to fall down.

Let's say we want to have a variable gravity intensity while what we could do then is we can check if

a movement or Y is bigger than zero which means we are jumping

then we can just apply regular gravity and if movement or Y is less than zero then we can do the same

but we can multiply the gravity.

For example one point five so 50 percent increase in gravity.

So now if we're going back to our game we jump normally the character will fall much faster as you can

see he's falling faster now.

After reaching his stop point in the jump okay.

That's it for jumping.
