Instance Variable Details

[hide private]

invalid

Test if the object has been freed by the game engine and is no longer valid.

Normally this is not a problem but when storing game engine data in the GameLogic module, KX_Scenes or other KX_GameObjects its possible to hold a reference to invalid data. Calling an attribute or method on an invalid object will raise a SystemError.

The invalid attribute allows testing for this case without exception handling.
