# How to make an easy platformer (collision)

How to make an easy platformer

here you can learn to make a easy platformer with the ‘gravity’ variable.

1st example

1st
Make a ‘gravity’ variable

2nd
Make a rule in the player:
(game starts)
((set {gravity} to {-9}
((repeat forever
Change Y by {gravity}))

3rd
Make another rule in player:
(when is touching {any object})
((set {gravity} to {0}))

Every code has it downs. If you use this, when touching, player will stop. Try it your self. Pictures in comments.

2nd example

We will use the ‘vertical velocity’ variable.
1st
make a new rule in player:
(when game is playing)
((change Y by {vertical velocity}))
((increase {vertical velocity} by {-1}

2nd
make another rule in player:
(when is touching {any object})
((set {vertical velocity} to {1}))
((change y by {1}))

This codes’ down is when collides it will go up.
