==General information==
TrackMania gamebox files (*.gbx) are generic container files that can contain everything from configuration to textures to track definitions. They consist of a header, a reference table and the body.
In old versions of TrackMania they used to be text files - nowadays they are binary files. Integers are stored in little endian order. The file body is often compressed (using LZO).
==Engines, classes, chunks==
A .gbx file more specifically stores the serialization of one or more class instances. There is one main instance, and optionally a number of auxiliary instances.
The serializable classes are organized into 16 ''engines''. Each class is also subdivided into ''chunks''. A class is then not serialized in one go, but rather as a series of chunks. This allows Nadeo to easily extend classes in new TrackMania versions: instead of having to define a new class they can simply add more chunks to an existing one, and have older versions ignore these new chunk types.
The data in a gbx file follows the pattern <chunk ID> <chunk data>. A ''chunk ID'' is a 32-bit number that identifies the engine, the class, and the chunk in that class. If you for example see the bytes <code>07 30 04 03</code> in the file, that would correspond to the integer 0x03043007, and be interpreted as follows:
engine class chunk
03 043 007
All engines and classes are named; in this case, engine 3 is the Game engine, and class 043 in that engine is CGameCtnChallenge. Chunks do not have names.
Apart from chunk ID's there are also ''class ID's'', which are just like chunk ID's except the chunk index part is ignored (and 0). For a complete overview of engines and classes, see [[Class ID's]].
==Header==
The header contains things like compression information and the class ID of the main class instance. The current version of the header also provides a few chunks of the main class that serve as meta information (e.g. the thumbnail of a challenge).
* byte[3] magic: "GBX"
* uint16 version: currently 6
* if version >= 3:
** byte format: 'B' or 'T': Binary or Text (always B for version 6 gbx files)
** byte compression: 'U' or 'C': Uncompressed or Compressed reference table (unused, always U)
** byte compression: 'U' or 'C': Uncompressed or Compressed body (typically C for binary files)
** if version >= 4:
*** byte unknown: 'R' or 'E': unknown purpose (typically R for binary files)
** uint32 classID (class ID of main class instance)
** if version >= 6:
*** uint32 userDataSize
*** byte[userDataSize]:
**** uint32 numHeaderChunks
**** HeaderEntry[numHeaderChunks]
***** uint32 chunkID
***** uint32 chunkSize (may have bit 31 set. This indicates a "heavy" header chunk which is skipped while scanning gbx files on game startup)
**** concatenated data of header chunks
** uint32 numNodes: the total number of class instances related to this gbx file. This includes the main instance, any local auxiliary instances, and any referenced external nodes/files. An internal list will be allocated with this number of entries; the main instance is at index 0.
==Reference Table==
* uint32 numExternalNodes: the number of external nodes and files that this .gbx references. These come from other files located in the .gbx's [[PAK|.pak]] file. The references to these will be placed in the same list as the local nodes (see above). Both raw files (e.g. textures) and .gbx main instances can be referenced.
* if numExternalNodes > 0:
** uint32 ancestorLevel: how many folder levels to go up in the .pak folder hierarchy to reach the base folder from which files will be referenced.
** uint32 numSubFolders
** Folder folders[numSubFolders]
*** string name
*** uint32 numSubFolders
*** Folder folders[numSubFolders]
** ExternalNode externals[numExternalNodes]
*** uint32 flags
*** if (flags & 4) == 0:
**** string fileName
*** else:
**** uint32 resourceIndex
*** uint32 nodeIndex (the index in the local node list where this external reference will be stored)
*** if version >= 5: (header version)
**** bool useFile (0 or 1, whether to use the file itself or the node that was loaded from the file)
*** if (flags & 4) == 0:
**** uint32 folderIndex: the depth-first index of the folder which the file is in. 0 means the base folder itself.
==Body==
* if body is compressed:
** uint32 uncompressedSize
** uint32 compressedSize
** byte data[compressedSize] (compressed with regular LZO)
* else:
** byte data[]
==Reading the body==
The file body contains further chunks of the main class instance, and may also contain auxiliary class instances. Reading the body is started by creating an in-memory instance of the class corresponding to the main class ID (instances are called ''nodes'' internally), and calling ReadNode on it:
ReadNode()
{
while(true)
{
chunkID = ReadUInt32();
if(chunkID == 0xFACADE01)
return;
chunkFlags = GetChunkFlags(chunkID);
if(chunkFlags & 0x10)
{
skip = ReadUInt32();
chunkDataSize = ReadUInt32();
}
ReadChunk(chunkID);
}
}
GetChunkFlags() doesn't read anything from the file; it provides loading flags for the specified chunk ID. The only important flag is whether or not the chunk is "skippable". If it is, the chunk ID is followed by an uint32 0x50494B53 ("SKIP", shows up as "PIKS" in the file due to little endian ordering) and an uint32 specifying the size of the chunk data. This allows older versions of TrackMania that don't know how to parse this chunk ID to skip over the chunk data and go to the next chunk. If the chunk is not skippable, the chunk data follows immediately after the chunk ID.
A dummy chunk ID of 0xFACADE01 signifies the end of the chunk list for the current class.
Chunk data is not self-describing; the program itself has to know how to read each one. In fact, if your program doesn't know a specific chunk ID and the chunk is not skippable, you can't even tell how long the chunk is.
We will first describe a number of "primitives" that are used when reading and writing chunks. Then we will describe the contents of a number of common chunks.
===Primitives===
* '''bool''': 32-bit little-endian integer that can be 0 or 1.
* '''byte''', '''uint16''', '''int32''', '''uint32''', '''uint64''', '''uint128''', '''float''': regular little endian encoding.
* '''vec2D''':
** float x
** float y
* '''vec3D''':
** float x
** float y
** float z
* '''color''':
** float r
** float g
** float b
* '''string''':
** uint32 length
** byte chars[length] (UTF8, older files sometimes with BOM, not zero-terminated)
* '''lookbackstring''': a form of compression which allows to avoid repeating the same string multiple times. Everytime a new string is encountered, it is added to a string list, and from then on this list entry is referenced instead of repeating the string another time.
** if this is the first lookback string encountered:
*** uint32 version (currently 3)
** uint32 index: bit 31 and 30 define the string type. If both bits are 0, the index is a [[ManiaPlanet_internals#Id|number]]. The actual index is bits 0-29. If it is 0, a new string follows (and will be added to the string list). If it is greater than one, use the string at stringlist [index - 1]. A value of -1 means there is no data provided (unassigned).
** if (index & 0xC0000000) != 0 and (index & 0x3FFFFFFF) == 0:
*** string newString. Append to the string list.
''Note'': the lookback string state is reset after each header chunk. The string list is cleared completely, and the next lookback string will again trigger the version number. If index represents a number (bits 30 and 31 not set), it describes the position inside a ''global'' string table. In most cases it concerns the ID of a collection. The correspondences used up to now are: 11 = 'Valley', 12 = 'Canyon', 17 = 'TMCommon', 202 = 'Storm', 299 = 'SMCommon', 10003 = 'Common'.
* '''fileref''': path to an external file, e.g. a skin.
** byte version (currently 3)
** if version >= 3:
*** byte[32] (checksum)
** string filePath (skin: if version < 2 relative to Skins folder else relative to user folder)
** if filePath.length > 0 && version >= 1:
*** string locatorUrl
* '''meta''': contains meta information like the track environment, time of day, and author.
** lookbackstring field1
** lookbackstring field2
** lookbackstring author
* '''noderef''': a reference to an auxiliary class instance.
** uint32 index. if this is -1, the node reference is empty (null).
** if the index is >= 0 and the node at the index has not been read yet:
*** uint32 classID: instantiate a new node for this class ID and store it in the node list at the specified index.
*** ReadNode()
''Note'': In case of a text format gbx file (marked by a 'T' in the header) all numbers and strings are stored as one line of ASCII text in each case. Every line ends with a carriage return-linefeed (<CR><LF>) combination (0x0D and 0x0A). A single <LF> is part of a string.

int16 axisHeading (-0x8000..0x7FFF -> -pi..pi)
int16 axisPitch (-0x8000..0x7FFF -> -pi/2..pi/2)
int16 speed (-> exp(speed/1000); 0x8000 means 0)
int8 velocityHeading (-0x80..0x7F -> -pi..pi)
int8 velocityPitch (-0x80..0x7F -> -pi/2..pi/2)
... (more unknown data)
The rotation of the car is calculated as a quaternion.
* The real part of the quaternion is calculated as cos(angle) which corresponds to a rotation of 2*angle around the rotation axis.
* The imaginary part of the quaternion (the rotation axis) is calculated as the vector (sin(angle)*cos(axisPitch)*cos(axisHeading), sin(angle)*cos(axisPitch)*sin(axisHeading), sin(angle)*sin(axisPitch)).
You can [http://en.wikipedia.org/wiki/Quaternions_and_spatial_rotation#Conversion_to_and_from_the_matrix_representation convert this quaternion to a transform matrix].
The velocity vector (direction and speed of movement) is calculated in a similar way: (speed*cos(velocityPitch)*cos(velocityHeading), speed*cos(velocityPitch)*sin(velocityHeading), speed*sin(velocityPitch)).

== Historical information ==
While the above description of *.Gbx files is far more complete and precise than before, it is also entirely different from – and more abstract than – the original description, which formed the basis for several of the tools below. That historical description can still be viewed at this [http://en.tm-wiki.org/index.php?title=GBX&oldid=5300 revision link].

TrackMania gamebox files (*.gbx) are generic container files that can contain everything from configuration to textures to track definitions. They consist of a header, a reference table and the body.
In old versions of TrackMania they used to be text files - nowadays they are binary files. Integers are stored in little endian order. The file body is often compressed (using LZO).
==Engines, classes, chunks==
A .gbx file more specifically stores the serialization of one or more class instances. There is one main instance, and optionally a number of auxiliary instances.
The serializable classes are organized into 16 ''engines''. Each class is also subdivided into ''chunks''. A class is then not serialized in one go, but rather as a series of chunks. This allows Nadeo to easily extend classes in new TrackMania versions: instead of having to define a new class they can simply add more chunks to an existing one, and have older versions ignore these new chunk types.
The data in a gbx file follows the pattern <chunk ID> <chunk data>. A ''chunk ID'' is a 32-bit number that identifies the engine, the class, and the chunk in that class. If you for example see the bytes <code>07 30 04 03</code> in the file, that would correspond to the integer 0x03043007, and be interpreted as follows:
engine class chunk
03 043 007
All engines and classes are named; in this case, engine 3 is the Game engine, and class 043 in that engine is CGameCtnChallenge. Chunks do not have names.
Apart from chunk ID's there are also ''class ID's'', which are just like chunk ID's except the chunk index part is ignored (and 0). For a complete overview of engines and classes, see [[Class ID's]].
==Header==
The header contains things like compression information and the class ID of the main class instance. The current version of the header also provides a few chunks of the main class that serve as meta information (e.g. the thumbnail of a challenge).
* byte[3] magic: "GBX"
* uint16 version: currently 6
* if version >= 3:
** byte format: 'B' or 'T': Binary or Text (always B for version 6 gbx files)
** byte compression: 'U' or 'C': Uncompressed or Compressed reference table (unused, always U)
** byte compression: 'U' or 'C': Uncompressed or Compressed body (typically C for binary files)
** if version >= 4:
*** byte unknown: 'R' or 'E': unknown purpose (typically R for binary files)
** uint32 classID (class ID of main class instance)
** if version >= 6:
*** uint32 userDataSize
*** byte[userDataSize]:
**** uint32 numHeaderChunks
**** HeaderEntry[numHeaderChunks]
***** uint32 chunkID
***** uint32 chunkSize (may have bit 31 set. This indicates a "heavy" header chunk which is skipped while scanning gbx files on game startup)
**** concatenated data of header chunks
** uint32 numNodes: the total number of class instances related to this gbx file. This includes the main instance, any local auxiliary instances, and any referenced external nodes/files. An internal list will be allocated with this number of entries; the main instance is at index 0.
==Reference Table==
* uint32 numExternalNodes: the number of external nodes and files that this .gbx references. These come from other files located in the .gbx's [[PAK|.pak]] file. The references to these will be placed in the same list as the local nodes (see above). Both raw files (e.g. textures) and .gbx main instances can be referenced.
* if numExternalNodes > 0:
** uint32 ancestorLevel: how many folder levels to go up in the .pak folder hierarchy to reach the base folder from which files will be referenced.
** uint32 numSubFolders
** Folder folders[numSubFolders]
*** string name
*** uint32 numSubFolders
*** Folder folders[numSubFolders]
** ExternalNode externals[numExternalNodes]
*** uint32 flags
*** if (flags & 4) == 0:
**** string fileName
*** else:
**** uint32 resourceIndex
*** uint32 nodeIndex (the index in the local node list where this external reference will be stored)
*** if version >= 5: (header version)
**** bool useFile (0 or 1, whether to use the file itself or the node that was loaded from the file)
*** if (flags & 4) == 0:
**** uint32 folderIndex: the depth-first index of the folder which the file is in. 0 means the base folder itself.
==Body==
* if body is compressed:
** uint32 uncompressedSize
** uint32 compressedSize
** byte data[compressedSize] (compressed with regular LZO)
* else:
** byte data[]
==Reading the body==
The file body contains further chunks of the main class instance, and may also contain auxiliary class instances. Reading the body is started by creating an in-memory instance of the class corresponding to the main class ID (instances are called ''nodes'' internally), and calling ReadNode on it:
ReadNode()
{
while(true)
{
chunkID = ReadUInt32();
if(chunkID == 0xFACADE01)
return;
chunkFlags = GetChunkFlags(chunkID);
if(chunkFlags & 0x10)
{
skip = ReadUInt32();
chunkDataSize = ReadUInt32();
}
ReadChunk(chunkID);
}
}
GetChunkFlags() doesn't read anything from the file; it provides loading flags for the specified chunk ID. The only important flag is whether or not the chunk is "skippable". If it is, the chunk ID is followed by an uint32 0x50494B53 ("SKIP", shows up as "PIKS" in the file due to little endian ordering) and an uint32 specifying the size of the chunk data. This allows older versions of TrackMania that don't know how to parse this chunk ID to skip over the chunk data and go to the next chunk. If the chunk is not skippable, the chunk data follows immediately after the chunk ID.
A dummy chunk ID of 0xFACADE01 signifies the end of the chunk list for the current class.
Chunk data is not self-describing; the program itself has to know how to read each one. In fact, if your program doesn't know a specific chunk ID and the chunk is not skippable, you can't even tell how long the chunk is.
We will first describe a number of "primitives" that are used when reading and writing chunks. Then we will describe the contents of a number of common chunks.
===Primitives===
* '''bool''': 32-bit little-endian integer that can be 0 or 1.
* '''byte''', '''uint16''', '''int32''', '''uint32''', '''uint64''', '''uint128''', '''float''': regular little endian encoding.
* '''vec2D''':
** float x
** float y
* '''vec3D''':
** float x
** float y
** float z
* '''color''':
** float r
** float g
** float b
* '''string''':
** uint32 length
** byte chars[length] (UTF8, older files sometimes with BOM, not zero-terminated)
* '''lookbackstring''': a form of compression which allows to avoid repeating the same string multiple times. Everytime a new string is encountered, it is added to a string list, and from then on this list entry is referenced instead of repeating the string another time.
** if this is the first lookback string encountered:
*** uint32 version (currently 3)
** uint32 index: bit 31 and 30 define the string type. If both bits are 0, the index is a [[ManiaPlanet_internals#Id|number]]. The actual index is bits 0-29. If it is 0, a new string follows (and will be added to the string list). If it is greater than one, use the string at stringlist [index - 1]. A value of -1 means there is no data provided (unassigned).
** if (index & 0xC0000000) != 0 and (index & 0x3FFFFFFF) == 0:
*** string newString. Append to the string list.
''Note'': the lookback string state is reset after each header chunk. The string list is cleared completely, and the next lookback string will again trigger the version number. If index represents a number (bits 30 and 31 not set), it describes the position inside a ''global'' string table. In most cases it concerns the ID of a collection. The correspondences used up to now are: 11 = 'Valley', 12 = 'Canyon', 17 = 'TMCommon', 202 = 'Storm', 299 = 'SMCommon', 10003 = 'Common'.
* '''fileref''': path to an external file, e.g. a skin.
** byte version (currently 3)
** if version >= 3:
*** byte[32] (checksum)
** string filePath (skin: if version < 2 relative to Skins folder else relative to user folder)
** if filePath.length > 0 && version >= 1:
*** string locatorUrl
* '''meta''': contains meta information like the track environment, time of day, and author.
** lookbackstring field1
** lookbackstring field2
** lookbackstring author
* '''noderef''': a reference to an auxiliary class instance.
** uint32 index. if this is -1, the node reference is empty (null).
** if the index is >= 0 and the node at the index has not been read yet:
*** uint32 classID: instantiate a new node for this class ID and store it in the node list at the specified index.
*** ReadNode()
''Note'': In case of a text format gbx file (marked by a 'T' in the header) all numbers and strings are stored as one line of ASCII text in each case. Every line ends with a carriage return-linefeed (<CR><LF>) combination (0x0D and 0x0A). A single <LF> is part of a string.

int16 axisPitch (-0x8000..0x7FFF -> -pi/2..pi/2)
int16 speed (-> exp(speed/1000); 0x8000 means 0)
int8 velocityHeading (-0x80..0x7F -> -pi..pi)
int8 velocityPitch (-0x80..0x7F -> -pi/2..pi/2)
... (more unknown data)
The rotation of the car is calculated as a quaternion.
* The real part of the quaternion is calculated as cos(angle) which corresponds to a rotation of 2*angle around the rotation axis.
* The imaginary part of the quaternion (the rotation axis) is calculated as the vector (sin(angle)*cos(axisPitch)*cos(axisHeading), sin(angle)*cos(axisPitch)*sin(axisHeading), sin(angle)*sin(axisPitch)).
You can [http://en.wikipedia.org/wiki/Quaternions_and_spatial_rotation#Conversion_to_and_from_the_matrix_representation convert this quaternion to a transform matrix].
The velocity vector (direction and speed of movement) is calculated in a similar way: (speed*cos(velocityPitch)*cos(velocityHeading), speed*cos(velocityPitch)*sin(velocityHeading), speed*sin(velocityPitch)).

== Historical information ==
While the above description of *.Gbx files is far more complete and precise than before, it is also entirely different from – and more abstract than – the original description, which formed the basis for several of the tools below. That historical description can still be viewed at this [http://en.tm-wiki.org/index.php?title=GBX&oldid=5300 revision link].
== Applications and Libraries that can inspect/modify the file format ==
