Extending mouseEvent class

Question

Hey guys,
I'm trying to see if I can add a parameter to pass a Number
Variable through AddEventListener. I'm trying to create a custom
class. Here's what I have thus far.
This would be called using an EventListener, with an
additional parameter, looking something like this.
But I'm getting errors thrown at me when I try to run this:
1046: Type was not found or was not a compile-time constant:
_mapNum.
and
5000: The class 'mapMouse' must subclass
'flash.display.MovieClip' since it is linked to a library symbol of
that type.
Any suggestions would be greatly appreciated.
THANKS!!!

Answer 1

this looks a little confusing!
some issues i can see with your code:
you're defining your MapNumber parameter by the variable type
_mapNum. but _mapNum isn't a variable type(eg String, Number, etc),
it's a variable. This is why you're getting the error:
1046: Type was not found or was not a compile-time constant:
_mapNum.
i would guess that you're subclassing your 'mapMouse' symbol
with the MapMouse class, which you're extending with MouseEvent.
MovieClip symbols can only be subclassed by classes that are
subclassed by MovieClip(or Sprite). This is why you're getting the
error:
5000: The class 'mapMouse' must subclass
'flash.display.MovieClip' since it is linked to a library symbol of
that type.
Your addEventListener parameters are a little strange.
Perhaps you should have a look at parameters Flash expects in help.
For example, in your first addEventListener call, _mapNum should be
a listener function rather than a number. mapChange should be a
Boolean indicating if you want to useCapture.(this parameter is not
necessary)
