Legacy:Object

UT2003 :: Object (Package: Core)

UT2004 :: 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 Unreal. 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 (a texture map), TextBuffer (a chunk of text), and Class (which describes the class of other objects).

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 (UT) for the UT version and Object (UT3) for the UT3 version of this class.

Properties

name Name (native, const, editconst, noexport) 

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'Engine.Mutator' is class'Core.Class', the class of an actual Mutator actor is class'Engine.Mutator'.)

pointer ObjectInternal[7] (native, private, const) 

(like all pointer variables declared as int in engine build 2136 and earlier)

Object Outer (native, const) 

int ObjectFlags (native, const) 

Constants

Pi = 3.1415926535897932

MaxInt = 0x7fffffff = 2147483647 

Maximum possible integer value. Minimum integer: ~MaxInt = 0x80000000 = -2147483648

Used for ObjectFlags:

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 Function 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.

Created ( ) 

Called for non-Actor objects when they are created using New.

Daid303: I've found some extra function in the new demo of UT2004:

native final function bool PlatformIsMacOS();  
 
native final function bool PlatformIsUnix();  
 
native final function bool PlatformIsWindows();  
 
native final function bool PlatformIs64Bit();

You can simply find stuff like that by opening U files in notepad. See if people can find other new native stuff :)

Foxpaw: ! Functions to check what platform it is? Why that's plum crazy! Plums! Seriously though, it seems rather un-cross-platformy to have functions like that, but I'd be interested to see how they've been used in UT2004.

MythOpus: Hasn't the time sub-system been in the C Headers since the orginial UT? How come it still hasn't been implemented?

OlympusMons: Added the other related topics, not sure if all these links are fully related to object or should really go here or not.
