Alex: actually this is a simple as3.0 project compiling with the cmd line compiler.
Is the stage defined at the same time the the root object is available? I am sure there are reasons but not having stageHeight as a global property makes me confused as to why? should any sprite (whether it is nothing) as long as it's added to the display list be able to access the stage property? Sorry, for the lame questions but I've been passing in the stageHeight, where I can get, it to all my sub classes in their constructor... not ideal but I can only seem to get the stageHeight properly from one sprite. I just can't figure out the rules of the stage why some sprites can access the stage.stageHeight and others can not. the dreaded NULL OBJECT REFERENCE reminds me of our president. By the way, do people mind pure AS3.0 questions on this list or is it better on flashcoders? There's still a lot of as2.0centric questions over there and it seems like flexcoders are a great source of information 3.0centric. OK, good night, thanks for the help.
