Components

The IDs are derived from an FNV32 hash of the Component name. Each component defines an aspect of the object, and may require specific data (see below) supplied.

ID	Component	Comments
0x1A8fEB14	Physics	Always included except for plants
0x22706EFA	Sim	Object is a sim (simOutfitKey optional)
0x23177498	Script	Object has a game script (scriptClass key required)
0x2954E734	Model	Object has a model (modelKey required) - unused for plants

footprintKey	ResourceKey	Footprint	Only used if modelKey is not a VPXY
modelKey	AssetResourceName ResourceKey	Model Tree	References a VPXY References SPT data
scriptClass	String	Script	Class name to instantiate to simulate this object
simOutfitKey	ResourceKey	Sim	Optional when the Sim component is included Points to a sim outfit (XML or binary)
steeringInstance	SteeringInstance	Steering	Required if Steering component included Can be Car, Bicycle or Sim

Component data types

type represents to a "ComponentDataType", which is defined as the following basic data type:

type	ComponentDataTypes	data
00	String	DWORD(length) STRING[length]
01	ResourceKey	DWORD index to TGI64 at end
02	AssetResourceName	DWORD index to TGI64 at end
03	SteeringInstance	DWORD(length) STRING[length]
04	UInt32	DWORD

VisibilityFlag

value	Description
00	VisibleAlways
01	VisibleInToolsOnly
02	VisibleAsDistantTerrain
