Object Categories

An object's category specifies parts of its behavior. For a definition it is set by the Category entry in the DefCore.txt file. Multiple categories can be combined using the binary OR operator.
A category also specifies the default plane an object is drawn in if it doesn't specify this property itself. The higher the plane number, the further in the front an object is drawn. See Properties.
