Data Structures
class	RoR::Actor
	Softbody object; can be anything from soda can to a space shuttle Constructed from a truck definition file, see https://docs.rigsofrods.org/vehicle-creation/fileformat-truck/ To spawn in-game, use MSG_SIM_SPAWN_ACTOR_REQUESTED, see GameContext::PushMessage(), in AngelScript use game.pushMessage(); Gameplay states are described by enum ActorState. More...
class	RoR::ActorManager
	Builds and manages softbody actors (physics on background thread, networking) More...
class	RoR::ActorSpawner
	Processes a RigDef::Document (parsed from 'truck' file format) into a simulated gameplay object (Actor). More...

struct	RoR::FreeForce
	Global force affecting particular (base) node of particular (base) actor; added ad-hoc by scripts. More...
struct	RoR::FreeForceRequest
