# Object (UT)

UT :: Object (Package: Core)

Object, the root class. All other classes are more or less directly derived from Object.

Object is the parent class of all objects in the Unreal Engine. All of the functions in the Object class are accessible everywhere, because everything derives from Object. Object is an abstract base class, in that it doesn't do anything useful. All functionality is provided by subclasses, such as Texture (UT) (a texture map), TextBuffer (a chunk of text), Class (which describes the class of other objects) or Actor (UT) (basically everything you can see in Unreal/UT levels).

The UnrealScript compiler insists that you specify "`extends Object`" if you're extending Object, i.e. it does not implicitly extend the Object class if you forget to add it.

See Object for the UT2003 version of this class.

## Properties

name Name (native, const, editconst)
  The name of this object. The string representation of this value is the same like the last part of the object's string representation.
class Class (native, const, editconst)
  The class of this object. (The class of e.g. `class'Botpack.Enforcer'` is `class'Core.Class'`, the class of an actual Enforcer actor is `class'Botpack.Enforcer'`.)
int ObjectInternal[6] (native, private, const)
Object Outer (native, const)
  This object's parent object, i.e. the object which "contains" this object.
int ObjectFlags (native, const)

## Constants

Pi = 3.1415926535897932
MaxInt = 0x7fffffff = 2147483647
  Maximum possible integer value. Minimum integer: `~MaxInt = 0x80000000 = -2147483648`

Used for the `ObjectFlags` property:

RF_Transactional = 0x00000001
  Object supports editor undo/redo.
RF_Public = 0x00000004
  Object can be referenced by external package files.
RF_Transient = 0x00004000
  Object can't be saved or loaded.
RF_NotForClient = 0x00100000
  Don't load the object for game client.
RF_NotForServer = 0x00200000
  Don't load the object for game server.
RF_NotForEdit = 0x00400000
  Don't load the object for editor.

## Methods

The Object class contains the declarations for the global functions and operators you can use in UnrealScript.

There are some other important function declarations in the Object class:

BeginState ( )
  Called when executing the `GotoState` method right after the object's state has changed.
EndState ( )
  Called by `GotoState` right before the state changes. This will also be called when an Actor's `Destroy` method is used.

Note that states can only be used in subclasses of Actor (UT) and Console.
