This is a simple snippet to make a fixed third person camera in the newly released Unreal Development Kit (UDK). Found in this thread.

class RPGController extends UTPlayerController;


//Camera Calculations

var vector LastViewLoc;

var vector CameraOffset;

var vector CameraOffset2;


//Force third-person

function SetBehindView( bool bNewBehindView )

{

	super.SetBehindView( true );

}


// RPG Camera (based on Third-Person Camera)

simulated event GetPlayerViewPoint( out vector POVLocation, out Rotator POVRotation )

{	

	if ( ViewTarget != none )

	{

		LastViewLoc = ViewTarget.Location;

		bCollideWorld = true;

		

	}

	

	POVLocation = LastViewLoc + CameraOffset2;

	POVRotation = rotator( -CameraOffset );

	

	StopViewShaking();

	

	if ( CameraEffect != none )

		CameraEffect.UpdateLocation( POVLocation, POVRotation, GetFOVAngle( ) );

}


// Allows the mouse to still aim weapons

function rotator GetAdjustedAimFor(Weapon W, vector StartFireLoc)

{

     return Pawn.Rotation;

}


defaultproperties

{

	//Camera

	bBehindView=true;

	CameraOffset=(X=1,Y=1,Z=1)

	CameraOffset2=(X=200,Y=200,Z=300)

}
