Question

I’m developing a rendering engine for a game i am currently building..

I have a main camera (rectangle) that determines what needs to be rendered (thing within it’s boundaires)

I am using a bitmap rendering method for the background and that all works fine.

but for the character i am using a movieclip over the top.

when the character goes out of the camera’s view is it 100% neccesary to set visible=false?

atm the game is running at 30 FPS (as intended) and everything is sweet, i just wanted to ask out of curiosity.

Is flash clever enough to not bother with movieclip outside of the scene boundaires?

Thanks in advance,
Rory

According to http://help.adobe.com/en_US/as3/dev/WS5b3ccc516d4fbf351e63e3d118a9b90204-7e3e.html Flash won’t render if an object is outside of Stage boundaries:

Display list

The hierarchy of display objects that will be rendered as visible
screen content by Flash Player and AIR. The Stage is the root of the
display list, and all the display objects that are attached to the
Stage or one of its children form the display list (even if the object
isn’t actually rendered, for example if it’s outside the boundaries of
the Stage).
