Object Key - OBJK
Game Version:The Sims 3



Identifies what kind of object this is and what its behaviour is.


DWORD version // 7
DWORD TGI_offset // see Sims 3:Key table
DWORD TGI_size   // see Sims 3:Key table

// Components - see below 
BYTE count1
--repeat count1 times
   DWORD Component ID

// Component data - see below
BYTE count2
--repeat count2 times
   DWORD length
   BYTE type // see below

BYTE VisibilityFlag

--insert TGI Block List


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.

01 ResourceKey DWORD index to TGI64 at end
02 AssetResourceName DWORD index to TGI64 at end
03 SteeringInstance DWORD(length) STRING[length]
