Just another Function for your pleasure. Have fun with it. 
movieclip.prototype.katapult = function (hoehe,propX,propY,checkProp) {
    if (signal != true) {
        dim = random(30)/10;
        _width = 2+(dim/2);
        _height = 2+(dim/2);
    }
    signal = true;
    this[propY] += dim;
    this[propX] += (random(10)/10);
    this[propX] -= (random(10)/10);
    if (this[checkProp]>hoehe) {
        this[checkProp] = 0;
