# Actor

UT2003 :: Object >> Actor (Engine)

This page is the technical specification for the Actor class. See Actor Overview for information on working with actors in UnrealEd.

Objects that have a position in the world are subclassed from Actor. For example brushes, movers, decorations, Bot (UT)s, Light (UT)s and Triggers (UT). This is an important class because it's the base class for all in-game objects (as in "object oriented programming"), so you'll find really a lot of very important functions and variables defined in this class. UnrealScript beginners ought to take a look at this class's source code.

For this class in UT see Actor (UT).
