Actionscript question


Recommended Posts

If someone could explain what exactly this code is doing, I'd really appreciate it. I know it's scaling and moving the image I just don't understand what the point of all the math is and why you wouldn't just pass the value you wanted. confused... thanks for any help :)function moveAndScale(instanceName, targetWidth, targetHeight, targetX, targetY, factor) { instanceName._x += (targetX-instanceName._x)/factor; instanceName._y += (targetY-instanceName._y)/factor; instanceName._width += (targetWidth-instanceName._width)/factor; instanceName._height += (targetHeight-instanceName._height)/factor;
