hey all,

i have the simple easing code:

bg\_mc.onEnterFrame=function(){  
speed = 30;

this.\_x+=(\_root.\_xmouse-this.\_x)/speed;  
this.\_y+=(\_root.\_ymouse-this.\_y)/speed;  
}

// ok this work fine on a small movieclip  
but when my movieclip is 5500 x 5500 px big;  
the small movements are to fast…  
so what is a smart Math way to calculate if the mouse is moved slowly the speed is also slowly if the user moves fast the speed is very fast
