Need help!
I got this code but the guy just falls through the floor.
I got an mc inside stick that's called feet, and the ground called... ground!
The codes that aquire the while loop are in bold.

leftrot=_root.stick.body.leftarm._rotati on;
rightrot=_root.stick.body.rightarm._rota tion;
grav=2;
acc=.25;
rspeed=0;
lspeed=0;
jspeed=10;
bspeed=3;
lacc=.2;
racc=.2;
jump=false;
ready=false;
numCopies=50;
copyCount=0;
ball.swapDepths(50000);
stop();
stick.onEnterFrame=function(){
var point:Object = new Object();
point.x = this.feet._x;
point.y = this.feet._y;
this.localToGlobal(point);
this.body.leftarm._rotation+=grav/Math.P I;
this.body.rightarm._rotation-=grav/Math.
PI;
if(grav<=0){
this.body.leftarm._rotation=leftrot;
this.body.rightarm._rotation=rightrot;
}
if(this.body.leftarm._rotation>=90){
this.body.leftarm._rotation-=grav/Math.P I;
this.body.rightarm._rotation+=grav/Math.
PI;
}
cam._x=this._x;
cam._y=this._y;
if(!_root.ground.hitTest(point.x,point.y ,true)){
grav+=acc;
