I'm not sure if you want to do it this way, but this give you the coords in parent space:

127 ss2d.DisplayObject.prototype.worldToLocal = function(point)
128 {
129 var worldMatrix = this.getWorldTransformationMatrix();
130 var invWorldMatrix = worldMatrix.invert();
131 var transformedPoint = invWorldMatrix.transformPoint(point);
132 return transformedPoint;
133 };

, but I think it would be more useful if the transformation of the object is included, that I'm expecting when converting from world space to local

ss2d.DisplayObject.prototype.worldToLocal = function(pointf)
{
var targetMatrix = new ss2d.Matrix3();
var worldMatrix = this.getWorldTransformationMatrix(targetMatrix, null, true);
var invWorldMatrix = worldMatrix.invert();
var transformedPoint = invWorldMatrix.transformPoint(point);
return transformedPoint;
};

This code example can reproduce an error:

var loading_screen;
var loading_text;
var is_loading = false;

function toggleLoadingScreen(  ) {
    if ( !is_loading ) {
        is_loading = true;
        loading_screen = new ss2d.Quad( 0, 0, view.mCanvas.width, view.mCanvas.height, '#000000' );
        view.mMainScene.addObject( loading_screen );
        var loading_text = new ss2d.TextSprite( 50, 50, 'Some Text', '#ffffff', 25, 'Arial', 'bold' );
        view.mMainScene.addObject( loading_text );
    } else {
        is_loading = false;
        view.mMainScene.removeObject( loading_screen );
        view.mMainScene.removeObject( loading_text );
    }
}

The error is TypeError: a is undefined on line 2306, part of ss2d.DisplayObjectContainer.prototype.removeObject. Black quad removes with no error, but text remains on screen because of the error.
