Pawn

UT2003 :: Actor >> Pawn (Package: Engine)

This is the parent class for all Controlled entities in the game engine, whether they are controlled by human players or AI. Their purpose is to represent the visual and physical elements of the entity, while the Controller class handles their decision making, Adrenaline, etc.

Called by physics when the pawn begins crouching.
StartCrouch( float HeightAdjust )
Called by physics when the pawn ends crouching.
PlayDying( class<DamageType> DamageType, vector HitLoc ) (simulated)
UT2004: This function seems to be called natively on clientside. It's ROLE on clientside seems to be set to ROLE_Authority before. Although there is a ClientDying() method in Pawn, it is overwritten in xPawn and does therefore NOT call the controller's ClientDying() which "could" call PlayDying(). Controller.PlayDying() is not simulated, it wouldn't be called anyways. Magic ladies and gentlemen.

Discussion

Mysterial: Whew! Even though the Class Wikifier did half the work, that still took a while! I'll get to the functions and other stuff later.

Eyaw_Nayr: This class is probably one of the most important in the game. We should include things like how to modify pawns, etc ... Essentially we just need more details.

mono_eric3: Am I correct in thinking the movement animations are handled natively? Does anyone know of a way to prevent them playing, or at least have some sort of input in what is played (apart from setting those default variables of course). It would be nice if this page could be extended to cover natives and what can be done about them in the pawn class.

SuperApe: Those default properties (MovementAnims, etc) combine with the UnrealPawn and xPawn properties to make the full list of available anims. Within Actor, bAnimOwner dictates whether the Owner is in charge of the animations. Controller.bControllAnimations dictatates that the controller is in charge, rather than the Pawn notifications. It seems you could prevent movement animations from playing (on a player) simply by removing the values from those Pawn (UnrealPawn and xPawn) animation properties. Marked up properties, functions, etc.

SuperApe: Is the property bRollToDesired obsolete or broken? Has anyone use this property set to True succesfully? While True, it seems to disable bRotateToDesired, at least with PHYS_Flying.
