cull is a section in the item placement file in Grand Theft Auto III, Grand Theft Auto: Vice City, Grand Theft Auto: San Andreas, and Grand Theft Auto IV. It is used to create zones affecting the different behavior of the world, like mirrors, fixed camera positions, disabling rain, and police behaviors, when the player is within the zone.

Format

GTA III and GTA Vice City

Cull zones in GTA III and GTA Vice City are built by a box which is controlled by various attributes. By default, most of the cull zones are located in \data\maps\cull.ipl for both games, although GTA III doesn't seem to use this file. Instead it uses the cullzone.dat file to define these zones.

cull
CenterX, CenterY, CenterZ, X1, Y1, Z1, X2, Y2, Z2, Attribute, WantedLevelDrop
end

	Identifier	Type	Description
A,B,C	CenterX, CenterY, CenterZ	float[3]	A point which defines the center of the box in real world coordinates.
D,E,F	X1, Y1, Z1	float[3]	A point which corresponds to the corner of the box, usually the lower left.
G,H,I	X2, Y2, Z2	float[3]	A point which corresponds to the opposite corner of the box, usually the upper right.
J	Attribute	integer	The attribute in flag field representation (see below).
K	WantedLevelDrop	integer	Usually 0

Changing the zones center coordinates does not directly affect the zone itself. Anyway this vector should always point to the real center of the zone since those values are used to calculate the distance of several instances (e.g. the player) to the zone itself.

GTA San Andreas / IV

GTA San Andreas has two different major formats in the game:

CenterX, CenterY, CenterZ, Unknown1, Length, Bottom, Width, Unknown2, Top, Flag, Unknown3

CenterX, CenterY, CenterZ, Unknown1, Length, Bottom, Width, Unknown2, Top, Flag, Vx, Vy, Vz, Cm

Coordinates are always rounded to the nearest world unit so that they are no longer floating point values, they are non-decimal integers.

Value	Description
CenterX, CenterY, CenterZ	Vector to the center of the cull zone.
Unknown1, Unknown2, Unknown3	Allways 0.
Length	Dimensions of the zone along y-axis.
Width	Dimensions of the zone along x-axis.
Top, Bottom	Absolute Z coordinate of the top and bottom of the box.
Flag	The behaviour of the cull zone (see below).
Vx, Vy, Vz, Cm	Mirror parameters.
