Hi every one, yes i am finally on AS3 and for good now, so this is my question.
I have created a SelectionSystem class that creates instences of a UIButton class and place them one after an other horizontaly.
My button MC has a hitZone and a titleMc Movieclips.
Every thing is working up to that point, the issues arise with "inheritance" form when i tried to create the VerticalMenu classes that is supposed to extends UIButton
and overright the function setPosition() to place the button in a vertical manner. i am getting this: "1120: Access of undefined property hitZone.", "1120: Access of undefined property titleMC."
now that in the linkage box of my Button i have put VerticalMenu it doesn't find hitZone or titleMc.
I have flipped every witch way i just cant figure it out, some help would be grealy apreciated as i am just stating on my AS3 journey
...
my Classes:
Code:
package

import flash.display.MovieClip;

{
//initMouseEvents();
}
public function Init(_systemData:Object, _id:Number)
{
id = _id;
setTitle(_systemData.Title);
setPosition();
//trace(2);
}

{
//var hitZone:MovieClip;

}
//set

inheritance issue in AS3
yes, well i was just trying different things, have you tried the code ?, Basicly the "Model/Concept" is all based on the book "flash application design solution" but the book was written in AS2 so i am trying to recreate the classes in AS3....but right now i can't find the solution. Every thing is working fine until you start using inheritance. After using inheritance if you have a MC1 in the MC that you have exended it doesn't recognize MC1.... and i can't find the way to declare MC1 in either classes ...
