Hi, is there a way to apply variables only once?  
Like in an MC when you can use Load to give it variables et c. Can you use anything like this for an function?

I have this problem:  
[AS]  
ai\_foe = function (target)  
{  
if (target.action == undefined)  
{  
target.action = “idle”;  
}  
if (target.hitTest (\_root.char))  
{  
target.action = “attack”;  
}  
switch (target.action)  
{  
case “idle” :  
target.gotoAndPlay (target.action);  
break;  
case “attack” :  
target.gotoAndPlay (target.action);  
break;  
case “dead” :  
target.gotoAndPlay (target.action);  
break;  
}  
};  
[/AS]  
The problem is that the target MC is going to freeze at the first frame of “action”, since this is loaded every onEnterFrame.  
How do i get around this?
