OnUpdate()

override void DayZPlayerCamera3rdPersonErc::OnUpdate	(	float	pDt,
		out DayZPlayerCameraResult	pOutResult )

update angles from input

base bone pos

apply shoulder dist

store distance

basically -> transform up vector (0,1,0) and read x coord -> and set is as roll

prev update

movement height

prev update

update angles from input

this is actually negative to yaw

base bone pos

apply shoulder dist

store distance
