I got this mouse trail effect from one of the tutorials and I would like to be able to constrain it to specified perimeters. I couldn’t figure it out im too noob with action scripting "=/ but heres my code(I changed it a bit)…flash mx pro btw…

menu\_drag.onEnterFrame = function() {  
var xMouse = \_root.\_xmouse;  
if(Math.abs(xMouse - this.\_x) \< 1) {  
this.\_x = xMouse;  
} else {  
this.\_x -= (this.\_x-xMouse) / 1000;  
}  
}

so just incase you didn’t get what im trying to do…I dont want the menu\_drag to go past a certain point on the x axis… plz help me 🙂 thanks
