Character jump help

programming

Hi,

I’m making a game, and I need my guy to jump. Right now, he jumps, but more appears about 60 pixels higher, and then falls down regularly (i have a working “gravity” effect).
I really need him to progress pixel by pixel instead of just springing around. I’ll attach the SWF so you know what i mean. (press up to jump)

Here’s my jump code:

    if (mainOnGround && !leftKeyDown && !rightKeyDown) {
        for (i=0;i<jumpHeight;i++) {
            mcMain.y -= jumpSpeed;
            mainOnGround = false;
        }
        for (i=0;i<jumpHeight;i++) {
            mcMain.y -= (jumpSpeed/2);
        }
            
    }

I have my variables set like this:

//whether or not the main guy is standing on something
var mainOnGround:Boolean = false;
//whether or not the main guy is jumping
var mainJumping:Boolean = false;
//the speed of the jump (must be divisable by 2)
var origJumpSpeed:Number = 0.0005;
var jumpSpeed:Number = origJumpSpeed;
//the maximum height of the jump (must be divisable by 2)
var jumpHeight:Number = 1000;

and the framerate at 100FPS

Thanks,
Kale
