actionscript-3

问题 I really have searched high and wide and i'm starting to think it may be my terminology that is preventing me from finding the answer.

问题 I'm loading a few huge images on my flex/as3 app, but I can't manage to catch the error when the flash player runs out of memory.

问题 Taking this thread to the next level and now making a Main.as class to display different "screens" of my game. For right now I only have 1 screen called ControlPanel, but this will eventually have multiple levels (each level will be a separate screen) and a level selection screen, etc. added. So at this point I'm losing control over how to give things access to the stage (in other words... it's getting really thick with multiple levels and this noob's brain is being overloaded lol). To start
