Jumping Animation

Question

Can anyone help me create a working jump animation? I had a working one, except it went below the screen. I implemented it so when the y axis is at the bottom, the velocity is equal to 0, making it land properly. But then that if statement override everything and jump did nothing. I have been trying this for ages but it won't work. Does anyone have any ideas for an jump animation that works.

Answer 1

4 adjustments have to be made:

1) define boost before using it.
defining a variable with a variable that doesn't exist yet won't be very effective

2)Add 'this.velY -= this.gravity; after this.y += this.velY;
This will emulate the gravity effect

3) replace 'else' to if(this.y >= 400)
This will stop gravity if the ground is hit

4) reassign velY every time the jump button is pressed.
Allows for multiple jumps
