use a while+ hitTest, then you can just modify your ground with the bump… and ANY hill in the ground will work

```auto

while(ground.hitTest(char._x, char._y, true)){
char._y--;
}

```

It doesn’t work!  
What’s wrong?  
Can someone tell me what to do!?😉

Here’s my actionscript:

```php
 
onClipEvent (load) {
 jumping = false;
 falling = true;
 speed = 0;
 jump = 14;
 healthX = _root.health._x;
 scoreX = _root.score._x;
 Xpos = this._x;
 Ypos = this._y;
 maxmove = 15;
 _root.maxshoottime = 100;
}
onClipEvent (enterFrame) {
 _x = Xpos-_root._x;
 _root.score._x = scoreX-_root._x;
 _root.health._x = healthX-_root._x;
 if (!_root.ground.hitTest(this._x, this._y, true) && !jumping) {
  this._y += 6;
 }
 if (!_root.shooting) {
  _root.timer = 0;
  _root.mvsp = _xscale/20;
 }
 if (_root.dead) {
  this.gotoAndStop("dead");
 } else {
  speed *= .85;
  if (dir == "right" && !_root.leftblock.hitTest(this._x+20, this._y, true)) {
   _root.health._x += speed;
   _root.score._x += speed;

   _root.icons._x += speed;
   _root.menu._x += speed;
   _root.hell._x += speed;

   _root._x -= speed;
  }
  if (Key.isDown(Key.LEFT)) {
   if (speed>-maxmove) {
    speed--;
   }

    with (_root.bulleter) {
     onEnterFrame = function () {
      if (_root.timer>_root.maxshoottime) {
       _root.shooting = false;
       unloadMovie(this);
      }
      _root.timer++;
      _x += _root.mvsp;
     };
    }
    attacking = true;
    speed = 0;
    this.gotoAndStop("shoot");
   }
  } else if (speed<1 && speed>-1 && !attacking) {

  }

    falling = true;
   }
   if (jump<-15) {
    jump = -15;
   }
  }
  if (falling) {
   this.gotoAndStop("fall");
  }
  if (Key.isDown(Key.DOWN)) {
   this.gotoAndStop("duck");
  }
  if (_root.ground.hitTest(this._x, this._y, true) && falling) {

   jumping = false;

 }

onClipEvent (keyUp) {
