As3 Static Method Call Internal Method

I downloaded a script from the internet and it works perfect. I started to adapt the code in it for a new application. But I get the following error 1061: Call to a possibly undefined method drawShape through a reference with static type Class.

When looking at the code I see that the method that is calling drawShape is a static method calling it as such: ShapeDrawer.drawShape(); Note that the ShapeDrawer class isn't being imported at all.

Then the drawShape method is as such: internal function drawShape() Can anyone explain to me why it may work in the application I downloaded and not mine. His was built for use with flash player 9 and mine is ten that may play a part.

This is what it looks like:

package puzzle
{
    import flash.geom.Point;    
    import utils.MyMath;

    public class PuzzleCaculater
    {
        public static function combineTwoPieces(pieceA:PuzzlePiece , pieceB:PuzzlePiece):void
        {
            for each(var drawingPiece in pieceB.unionPieces)
            {
                ShapeDrawer.drawShape(pieceA.graphicLayer , drawingPiece.shapeData , true);
                drawingPiece.disactive();
                drawingPiece.myGroup = pieceA.myGroup;
                drawingPiece.graphicLayer = pieceA.graphicLayer;
                pieceA.unionPieces.push(drawingPiece);
                drawingPiece.unionPieces = pieceA.unionPieces;
            }
        }
    }
}

package puzzle
{
    public class ShapeDrawer
    {
        internal function drawShape(target:Shape , drawingShapedata:Object , useBitmap:Boolean = true):void
        {
            var leftShape:Array= drawingShapedata.leftShape;
            var topShape:Array= drawingShapedata.topShape;
            var rightShape:Array= drawingShapedata.rightShape;
            var bottomShape:Array= drawingShapedata.bottomShape;
            var shapes:Array= [];
            shapes.push(leftShape);
            shapes.push(topShape);
            shapes.push(rightShape);
            shapes.push(bottomShape);
        }
    }
}

You define drawShape like this:

internal function drawShape(...)

And you must define it like this:

static internal function drawShape(...)

Thath will fix your problem, the internal keyword isn't the problem (because both classes are in the same package)

Read up on access modifiers. They are critical to OO design patterns in AS3 (and other OO languages), and a misunderstanding of them will cause troubles ;)

Internal: The internal methods or properties are build to be shared across a common package. You need not to extend or inherit to the classes having Internal members(Where as we do inherit in case of protected) for accessing them. The internal members/methods are like public to the classes those are in same package

Declaring this method as Public will most likely fix your sitch... Cheers!

The internal keyword will prevent this function from being called outside of the package. Try making it public and see if that fixes it.
