HEY GUYS! what's up?

i've been doing some here and there with gravity
and this is the thing that bugs me...

i cant get the guy to land PERFECTLY on a platform

yes it lands and stops but it changes position
(like it lands on top of the platform, then in the middle)

how to fix this?

ahm, here's the script i used:

code:


if (Key.isDown(Key.SPACE) && !jumping) {

		vel_y = 40;

		jumping = true;

	}

	if (jumping == true) {

		vel_y -= 6;

		if (vel_y <=-40) {

			vel_y = -40;

		}

		this._y -= vel_y;

	}

if (this.hitTest(_root.ground)) {

		vel_y = 0;

		jumping = false;

	}

	if (this.hitTest(_root.ground) && !jumping) {

		fall += 1;

		if (fall>40) {

			fall = 40;

		}

		this._y += fall;

	}


the ground there is the instance name of my platform

yeah, can anyone help me out with this,

THNX a BUNCH!
