Redefining a function on the fly? Possible?

[Sparticus007]

Hey all,

I have a method/function inside my class called "doSomething()". This function gets called once a frame.

I am trying to figure out if it's possible to redefine that function on the fly with code.

For example, For the first 100 frames of my move I want "doSomething()" to look something like this :

public function doSelected():void {
     trace("hello");
}

and then after 100 frames has passed I'd like "doSomething()" to be redefine to look like this :

public function doSelected():void {
     trace("bye");
}

Is this possible?

thanks for any advice you can give!

Get ready for a very subtle difference. You cannot redefine a method, which is what you have there, but you can re-assign a variable of type Function. So you could do something like this:

public var doSelected:Function = doSelected1;

public function doSelected1():void{
  trace("hello");
}

public function doSelected2():void{
  trace("bye");
}

at some point, you can re-assign doSelected to point to doSelected2:

doSelected = doSelected2;

Too fast 5. Too fast.


If you're going to just change up the trace() output, or something similar, I'd just pass an argument to the function.

function doSelected(_sayWhat:String):void {
    trace(_sayWhat);
}
doSelected("hello"); //output hello
doSelected("bye"); //output bye

Thanks guys. What 5TonsOfFlax said was what i was looking for.

Phix, I had simplified what i was doing just for the example. Passing a variable into the method won't work for what i am actually doing. But thanks anyways

Also why not a simple if:

public function doSelected():void {
     if(currentFrame <= 100) {
          trace("hello");
     }else{
          trace("bye");
     }
}
