```auto
class AddClass extends MovieClip {
	private var Func_without_param:Function;
	private var Func_with_param:Function;
	private function onRollOver():Void {
		//trace("Rolled");
	}
	private function onPress():Void {
		//call a function without parameter
		//Example: Func_without_param();
	}
	private function onRelease():Void {
		//call another function with parameter, it can be Func_with_param(paramA) or Func_with_param(paramA, paramB)
	}
	private function onReleaseOutside():Void {
		//same as onRelease
	}
	public function InputFunction(param_func:Function) {
		this.Func_without_param = param_func;
	}
}

```

In fla, I use drag and drop a movieclip to the stage (linkage -\> AS 2.0 class :AddClass). I don’t want to use attachMovie due to some reasons.  
Then, I use

```auto
myBtn.InputFunction(A_FUNCTION);

```

There are bunch of functions with or with parameters in the fla.

I don’t think the structure above is good. What’s the good way to add another function with parameters when I call? Because my function can be FUNCTION(paramA) or FUNCTION(paramA, paramB,…)

Any suggestion or advice?  
Thanks in advance!
