Sims 3:0x02D5DF13

Overview

Coordinates animations(and sounds?).

Format

Follows the RCOL format, with its own custom chunks. All data is aligned on DWORD boundries. These chunks have a lot of filler data(0xDEADBEEF) which is a "serialization sentinel" according to enum definitions. There are two types of chunks, definition chunks and decision graph node chunks. The definition chunks form a simple structure with data about the state machine. Decision graph nodes form a recursive data structure. References to decision graph node indexes can validly refer to any decision graph node.

Prop - Create Prop Node

The catalog resource ID references type 0x139f7591 (CatalogObjectResourceID) which does not exist in any packages. However, the instance does reference a valid catalog object ID.

Current speculation is that the blank values may be object create parameters, since the prop is created with no script intervention. However, none of the values are set in existing jazz data.

DWORD 'Prop' 
DWORD version       // 0x100
DWORD [S_Ad Index]  // Prop actor to create
DWORD blank
TGI64 propobject    // Catalog reference of prop to create
5 DWORDS blank

DWORD 'AcOp'
DWORD version // 0x100
DWORD index   // Actor to operate on

DWORD op      // Actor operation
