Some of the more commonly seen data types in Burnout Paradise.

CgsSet/CgsArray

A CgsSet, or Set, and CgsArray, or Array, is a contiguous series of elements of a specified data type, followed by the number of elements in use. If the elements are 64 bits long, the element count will usually (but not always) be succeeded by 4 bytes of padding; otherwise, it will have no padding.

Though technically separate, Set and Array have the same structure.

As an example, the below is the structure of Set<uint16_t, 8>.

Offset	Size	Type	Name	Description
0x0	0x10	uint16_t[8]	maElements	The elements in the array
0x10	0x4	uint32_t	muLength	The number of elements in use
0x14	0x4			padding

CgsBitArray/CgsFastBitArray

A CgsBitArray, or BitArray, and CgsFastBitArray, or FastBitArray, is a contiguous array of bits. Unlike an Array, the element count is not part of the structure, making it hardcoded.

Note that a BitArray is stored as a series of uint64_t. This can be confusing if the data is in little endian byte order. Due to this, every BitArray has a length which is a multiple of 8 bytes.

The below is the structure of BitArray<200>. Notice how even though the bits only take up 0x19 bytes, 0x20 bytes are allocated.

Offset	Size	Type	Name	Description
0x0	0x20	uint64_t[4]	maxBits	The elements in the array

CgsID

A CgsID is a typedef of uint64_t which is heavily used across the game. Its original intent appears to be as a new moniker for GtID, Criterion's in-house compressed string type, and it sees extensive use in this role. However, at times, it is also used to store the IDs colloquially referred to as GameDB IDs. Conversely, GameDB IDs are not always stored as a CgsID, commonly being a normal uint64_t or uint32_t instead.

Name	Type	Size
CgsID	uint64_t	0x8

Vectors

Vectors in Burnout Paradise are structures made up of floats. They are primarily used for positional values but have been used in other cases, such as colors and gear ratios. Though a number of types besides floats are technically supported, they are seemingly never used.

The below structures represent the data held, but many vectors use the VectorIntrinsic type, causing them to be 0x10 long regardless of their structure.

VectorIntrinsic

Name	Type	Size
VectorIntrinsic	float[4]	0x10

Vector2

Offset	Size	Type	Name	Description
0x0	0x4	float	x	X value
0x4	0x4	float	y	Y value

Vector3

Offset	Size	Type	Name	Description
0x0	0x4	float	x	X value
0x4	0x4	float	y	Y value
0x8	0x4	float	z	Z value

Vector3Plus/Vector4

Offset	Size	Type	Name	Description
0x0	0x4	float	x	X value
0x4	0x4	float	y	Y value
0x8	0x4	float	z	Z value
0xC	0x4	float	w	W value

Matrices

Matrices are structures made up of vectors. They see similar use to vectors but are three-dimensional rather than planar.

Matrix33

Offset	Size	Type	Name	Description
0x0	0x10	Vector3	xAxis	X axis
0x10	0x10	Vector3	yAxis	Y axis
0x20	0x10	Vector3	zAxis	Z axis

Matrix44

Offset	Size	Type	Name	Description
0x0	0x10	Vector4	xAxis	X axis
0x10	0x10	Vector4	yAxis	Y axis
0x20	0x10	Vector4	zAxis	Z axis
0x30	0x10	Vector4	wAxis	W axis

Matrix44Affine

Offset	Size	Type	Name	Description
0x0	0x10	Vector3	xAxis	X axis
0x10	0x10	Vector3	yAxis	Y axis
0x20	0x10	Vector3	zAxis	Z axis
0x30	0x10	Vector3	wAxis	W axis

Matrix44AffinePacked

Offset	Size	Type	Name	Description
0x0	0x10	Vector4	xAxis	X axis
0x10	0x10	Vector4	yAxis	Y axis
0x20	0x10	Vector4	zAxis	Z axis

Hashes

Burnout Paradise uses several different forms of hash. This section is meant to give a brief synopsis of them; their parent pages contain more information and context.

This list is incomplete and will be added to as time goes on.

CgsResourceID

A CgsResourceID is a 64-bit field storing a CRC32 hash of a given Bundle resource name. The 4 bytes preceding the hash are unused in Bundle 2 V2 and older, though later versions add fields which make extensive use of them.

Offset	Size	Type	Name	Description
0x0	0x8	uint64_t	mHash	CRC32 hash

HashInt

HashInt is a typedef of uint64_t. It is used in AttribSysVault resources to refer to GameDB IDs which have been lookup8 encoded. This type has several aliases, including ExportID, Key, AssetID, Type, and TypeID.

Name	Type	Size
HashInt	uint64_t	0x8

CgsSound::Playback::Name

This type is used in Registry resources and anything accessing streams through a Registry resource. It is a custom hash which was either developed in-house or at EA. Though it has its own type, it may be stored as a standard uint32_t.

Offset	Size	Type	Name	Description
0x0	0x4	uintptr_t	mHash	Custom hash

LanguageResourceHash

A LanguageResourceHash, though not explicitly defined as a type, is a bit inverted CRC32 hash (i.e., CRC32 with an output XOR of 0 instead of 0xFFFFFFFF) of the name of an entry in a Language resource. This name can usually be determined via the game's executable.
