help with jumps

[deathsangel]

No I want it so that cant jump is set to false either

1)when you get to the target height
2)when you let go of space.

Number 1 works, number 2 doesnt

Oh, I misread. When you're checking for SDL events, add a case for SDL_KEYUP.

ok thanks

To jump, add a Y+ velocity, say +20.
Then every tick, apply gravity, say -9

DId you forgot that SDL's coordinate system is awkard...?

whoops... Thanks for pointing that out.

I think that's the generally accepted way to put coordinates together. Negative is "up." For instance, take a game of Quake 2 or 3. "set gravity 100" pushes you down. "set gravity -100" flings you into the ceiling.
