I have a enemy movieClip named: enemy01. I am creating AI movement for this mc. Here is my code:

\_root.enemy01.speed = 1  
\_root.enemy01.turnRate = .05  
\_root.enemy01.agroRange = 200;  
\_root.enemy01.mode = “follow”  
\_root.enemy01.distanceX = 0;  
\_root.enemy01.distanceY = 0;  
\_root.enemy01.distanceTotal = 0;  
\_root.enemy01.moveDistanceX = 0;  
\_root.enemy01.moveDistanceY = 0;  
\_root.enemy01.moveX = 0;  
\_root.enemy01.moveY = 0;  
\_root.enemy01.totalmove = 0;

function updatePosition(follower:\_root.enemy01, target:\_root.Hero) {

//I will compute the distance between follower and target  
\_root.enemy01.distanceX = target.\_x-\_root.enemy01.\_x;  
\_root.enemy01.distanceY = target.\_y-\_root.enemy01.\_y;

//I will get the total distance as a number  
\_root.enemy01.distanceTotal = Math.sqrt(\_root.enemy01.distanceX \* \_root.enemy01.distanceX + \_root.enemy01.distanceY \* \_root.enemy01.distanceY);

//I will check to see if agro range  
if(\_root.enemy01.distanceTotal \<= \_root.enemy01.agroRange){  
\_root.enemy01.moveDistanceX = \_root.enemy01.turnRate \* \_root.enemy01.distanceX / \_root.enemy01.distanceTotal;  
\_root.enemy01.moveDistanceY = \_root.enemy01.turnRate \* \_root.enemy01.distanceY / \_root.enemy01.distanceTotal;  
\_root.enemy01.moveX += \_root.enemy01.moveDistanceX;  
\_root.enemy01.moveY += \_root.enemy01.moveDistanceY;  
\_root.enemy01.totalmove = Math.sqrt(\_root.enemy01.moveX \* \_root.enemy01.moveX + \_root.enemy01.moveY \* \_root.enemy01.moveY);  
\_root.enemy01.moveX = \_root.enemy01.speed \* \_root.enemy01.moveX / \_root.enemy01.totalmove;  
\_root.enemy01.moveY = \_root.enemy01.speed \* \_root.enemy01.moveY / \_root.enemy01.totalmove;

//I will move and rotate the follower  
if(\_root.enemy01.mode == “follow”)  
{  
\_root.enemy01.\_x += \_root.enemy01.moveX;  
\_root.enemy01.\_y += \_root.enemy01.moveY;  
\_root.enemy01.\_rotation = Math.atan2(\_root.enemy01.moveY, \_root.enemy01.moveX) \* radians;  
}  
else if(\_root.enemy01.mode == “run”)  
{  
\_root.enemy01.\_x -= \_root.enemy01.moveX;  
\_root.enemy01.\_y -= \_root.enemy01.moveY;  
\_root.enemy01.\_rotation = (Math.atan2(\_root.enemy01.moveY, \_root.enemy01.moveX) \* radians)+180;  
}  
}  
}

**This is the error I am getting:**  
The class or interface ‘\_root.enemy01’ could not be loaded. function updatePosition(follower:\_root.enemy01, target:\_root.Hero) {

If you know how to make a movieclip move on its own easier, please be a pal and share. Thanks!
