override get and set

[hobbis]

Getting some strange behaviour trying to override a private var:


private var _hit:Boolean = false;

public function get hit():Boolean { return _hit; }
public function set hit(b:Boolean):void
{
_hit = b;
}


//in child class

override public function get hit():Boolean { return _hit; }
override public function set hit(b:Boolean):void
{
_hit = b;
asset_mc.animation_mc.gotoAndPlay("capture");
}


In the child class, it doesn't know about _hit:

ReferenceError: Error #1065: Variable _hit is not defined.

So I guess I have to declare the _hit var in the child class as well? This seems a bit strange. Can someone explain how to override private properties using the get set methods? Thanks

Private fields are visible only in current class, use "protected" key word, if you want to use class member in subclasses.

For this case, you can actually skip the protected variable:


override public function set hit(b:Boolean):void
{
super.hit = b;
asset_mc.animation_mc.gotoAndPlay("capture");
}

You don't need to override the getter if it has the exact same functionality. That should save you a line of redundant code. Also, you can use the "super" keyword in the setter to access the functionality that you're overriding.
