Sly 1:GS

GS

Data Structure
Game	Sly Cooper and the Thievius Raccoonus
Official Name	Yes

Not to be confused with Graphics Synthesizer.

GS (game state) is a data structure in Sly Cooper and the Thievius Raccoonus. It contains information about the current state of the game world, including an array of world states which, in turn, each contain an array of level states.

Fields

The GS struct has the following fields

Offset	Size	Type	Name	Description
0x0	0x4	int	gsv	Unknown
0x4	0x4	int	cbThis	Size of this struct in bytes
0x8	0x4	int	nChecksum	Unknown, possibly compared against cbThis for integrity check
0xc	0x4	float	dt	Total time spent in game (secs)
0x10	0x19c8	struct WS[6]	aws	Array of world states
0x19d8	0x4	enum GAMEWORLD	gameworldCur	Current gameworld
0x19dc	0x4	enum WORLDLEVEL	worldlevelCur	Current worldlevel
0x19e0	0x4	int	clife	Lives count
0x19e4	0x4	int	ccharm	Charm count
0x19e8	0x4	int	ccoin	Coin count
0c19ec	0x4	int	grfgs	Unknown bitfield, possibly settings flags
0x19f0	0x4	int	grfvault	Bitfield of unlocked powerups
0x19f4	0x4	int	grfmovie	Unofficial name, probably called something else internally
0x19f8	0x4	enum FGS	fgs	Game state flags
0x19fc	0x4	int	last powerup?	Unofficial name, may be wrong

GRFGS and GRFVAULT are aliases of int.

World states array

Main article: WS

aws is an array of 5 WS structs, one for each world. In the release build, the order is as follows:

• 0: Intro
• 1: Underwater
• 2: Mesa
• 3: Voodoo
• 4: Snow
• 5: Clockwerk

Bitfields

There are three sets of bitfields/flags after the world states.

Settings flags (GRFGS)

The purpose of grfgs is unclear. At least some of the bits appear to be used for game settings.

Powerup flags (GRFVAULT)

grfvault is a bitfield representing unlocked powerups. Each bit corresponding to a particular powerup being unlocked.

Cutscene flags

There are 16 bits for the cutscene flags, with each bit corresponding to a particular cutscene being unlocked. It is probably also stored as a typedef alias of int but the type is currently unknown.

Game state flags (FGS)

The current game state is represented by the FGS enum, which has the following possible values:

Name	Value	Description
FGS_FirstClue	0x1
FGS_HalfClues	0x2
FGS_AllClues	0x4
FGS_FirstVault	0x8
FGS_SecondVault	0x10
