Question
converting values for scaling
Hi
I need to map one set of values to another to control the scaling of an MC.
I need the _y value of 482 to equal 15% _yscale, and the _y value to equal 100% _yscale.
The code I fudged so far goes:
this.scanner_mc.onEnterFrame = function(){
this._x = _root._xmouse;
updateAfterEvent();
}
this.beam_mc.onEnterFrame = function(){
this._x = _root._xmouse;
this._yscale = stretch;
stretch = laser_mc._y * -.41+215;
trace("STR="+stretch);
trace("MCY="+laser_mc._y);
updateAfterEvent();
}
this.laser_mc.startDrag(true, 80, 240, 660, 500);
I basically guessed at the values for 'stretch' but I know there has to be a smart trigonometry way of calculating it.
It is easier if I show you, so I posted an SWF/FLA so you can see what I am trying to acheive and the code I have used so far to get there.
