Common Data Types (Burnout Paradise)

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

= CgsSet/CgsArray = A, or  , and  , or  , 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,  and   have the same structure.

As an example, the below is the structure of.

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

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

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

= CgsID =

A  is a typedef of   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, commonly being a normal   or   instead.

A  can be encoded and decoded using CgsID Tool, which uses the functions listed in the subpage, or with BurnoutHasher. Both are command-line applications. Use  or   followed by the desired value to decode or encode; e.g..

= 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 under the vector name.

The below structures represent the data held. Some use the FPU model, where the vectors are represented by a series of float fields. Others use the VPU model where a 128-bit space is used (the  type), causing them to be 0x10 long regardless of their structure.

Vector3Plus
The FPU version of Vector3Plus does not appear to exist, or is never unused.

Mask4
Mask4 is like a Vector4, but using unsigned integers or bools instead of floats.

No FPU version is known to exist.

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

= 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.

Resource ID
A  is a 64-bit field storing a CRC32 hash of a given Bundle resource name converted to lowercase. 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. Most IDs' resource names can be determined by viewing the Bundle debug data, if present. Hashes can be generated using any of a variety of online or local calculators, such as crccalc.com.

Attribute hash
is a typedef of. It is used in AttribSys Vault resources to refer to GameDB IDs which have been lookup8 encoded. This type has several aliases, including,  ,  ,  , and.

Sound hash
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.

The same hash is used by the Voice Hierarchy resource type in the  and   types.

Language hash
A Language hash, though not explicitly defined as a type, is a JAMCRC CRC32 hash of the name of an entry in a Language resource. This name can usually be determined via the game's executable. You can encode to JAMCRC using a website such as Sunshine's CRC Calculator or crccalc.com, or you can calculate the CRC locally while either performing a bitwise NOT on the result or using an output XOR of 0.

= CgsRandom = Generates a random value.

= CgsUtf8 = Used for some strings, such as those in Language resources.
