Ok how do i make an object move towards the mouse(prefferably on a key press) but with a fixed speed. currently i am using:  
if(Key.isDown(Key.UP))  
{  
\_x+=Math.round((\_root.\_xmouse-\_x)/20);  
\_y+=Math.round((\_root.\_ymouse-\_y)/20);  
}

as you can see the speed depends on distance to mouse and hence is not constant…so what do i do?

PS: i am using flash 8 pro
