jumping on a slope!

I have this rather cool code for a _mc on a slope. The only problem I am having is making the sprite.mc change states/animation when the sprite.mc is jumping. Can you help? duh...

here's the code I have:

onClipEvent(load){
speed = 5;
gravity = 0;
r = _height/2; //radius
jumping = false;
jumpingheight = 15;
}

onClipEvent(enterFrame){

if(key.isDown(key.RIGHT)){
_x + =speed;
}
if(key.isDown(key.LEFT)){
_x - =speed;
}


if(key.isDown(key.UP) &&! jumping){
jumping = true;
gravity = -jumpheight;
}

if(!_root.ground.hitTest(_x,_y, true)){
gravity++;
_y+ = gravity;

}else{
jumping =false;
gravity = 0;

}
while(_root.ground.hitTest(_x,_y-1+r,true)){
jumping = false;
_y--;
}
}

Can you explain a little more your problem? Don't understand what do you mean with "changing states/animation"?

I've created a circle with instance name "jumper" and and a rectangle at the bottom with instance name "ground" and added next code into actions layer:

PHP Code:

---

var speed = 5;
var gravity = 0;
var r = jumper._height/2; //radius
var jumping = false;
var jumpingheight = 15;

jumper.onEnterFrame = function() {
    if(Key.isDown(Key.RIGHT)){
        this._x+=5;
    }
    if(Key.isDown(Key.LEFT)){
        this._x-=speed;
    }
    if((Key.isDown(Key.UP)) && (!jumping)){
        jumping = true;
        gravity = -jumpingheight;
    }
    if(!ground.hitTest(this._x,this._y, true)){
        gravity++;
        this._y += gravity;
    } else {
        jumping = false;
        gravity = 0;
    }
    while(ground.hitTest(this._x,this._y-1+r,true)){
        jumping = false;
        this._y--;
    }
}

Don't know if this helps you because, as I've mentioned above, I don't really understand what do you mean by "changing states/animation"...

P.S. If you want to add a smoother falling down and jumping up you can use a tweening class (for example caurina tweener - you can find it on the net).

changing states, I mean: apart from using Left & Right keypresses, use control and shift to incorporate a 'duck' and 'roll' animation.

thanks for the kind reply.
