Item Placement

Introduction

Item PLacement files are used to place objects into the GTA world, including objects, zones, paths, and a lot more.

Structure

The .ipl files are split up into many sections. How many of them you use in your file is optional, they can even be empty. Each section starts with a section identifier and ends with the keyword "end", both in a single line.

Example:

inst
...
end

INST

Positions of static and dynamic (object.dat) map objects.

GTA3 format:

id, name, x, y, z, sx, sy, sz, rx, ry, rz, rw

GTAVC format:

id, name, int, x, y, z, sx, sy, sz, rx, ry, rz, rw

GTASA format:

id, name, int, x, y, z, rx, ry, rz, rw lod

ID

Unique object identifier. Must match in IDE file identifier. (integer)

Name

Usually same as the .dff model file, without extension (string)

int

Interior number. Zero for outside. (integer)

x, y, z

Item placement coordinates. (floating point numbers)

sx, sy, sz

Item scale, scales visible model only, doesn't scale the collision model. (floating point numbers)

rx, ry, rz, rw

Item rotations. Defined as quaternion, quite sophisticated math is needed to translate it to Euler angles. A map editing program should be used to edit these.

lod

San Andreas only. This the line number in the current IPL file for the LOD which belongs to this object. The first item in IPL file is line number 0, second is number 1 and so on. A value of -1 means no LOD is used. (integer)

CULL

This creates rainfree zones, wastefree zones, map reflections, TV screens, and temporary fixed camera positions.
GTA3 and VC format:

x1, y1, z1, x2, y2, z2, x3, y3, z3, flag, 0

x2, y2, z2

lower-left corner of the areabox

x3, y3, z3

upper-right corner of the areabox

SA format:

centerX, centerY, centerZ, 0, Ywidth, bottomZ, Xwidth, 0, topZ, Flag, Vx, Vy, Vz, Cm

Cull zone boundaries in San Andreas are aligned to the nearest world unit.

PATH

Ped, Car and Boat Paths, defines paths relative to the world centre. Only used in GTA VC, this format is much easier than in GTA3 where the paths were stored in IDE files, and GTA-SA paths which are stored in **nodes.dat inside gta3.img. This is a quite complicated format and hardly usable without an editing program (such as Ked).

GTA SA uses compiled binary files for its paths.

GRGE

This creates garages for the main.scm to use. Only used in San Andreas.
SA only:

X1, Y1, Z1, frontX, frontY, X2, Y2, Z2, Door, Type, Name

FrontX, Y

lower right front

Door

Type

Name

used to edit garage through the SCM

Grge Door Types

ID	Description
2	Carbomb with 5 second detonator
3	Carbomb which detonates when vehicle is next started after you exit it
4	Carbomb with remote-control detonator, like the satchel charges
5	Spray garage

ENEX

This creates interior connection to real world by placing yellow markers on the map for CJ to walk through.
SA only:

X1, Y1, Z1, ROT, R1, R2, C8, X2, Y2, Z2, Rot2, Int, Mark, Name, Sky, I2, Time On, Time Off

X1, Y1, Z1

ROT

R1

MULT

San Andreas only, this was never used in the game. This section is currently unknown and may never be known.

Maybe it was an Commentsection for times the engine didnt know the #-Command, because you can add anything you want there and the game doesnt crash. That means this section is ignored.

CARS

Only used in San Andreas, this creates permanent parked vehicles around the state. Rockstar only used in binary IPLs but it can also be used in regular IPLs.
SA only:

X, Y, Z, angle, car id, primary color, secondary color, bool?, alarm_probability, 
door_lock_probability, dword (radio?), dword (appearance delay?)

OCCL

This creates occlusion boxes around Vice City and San Andreas.
VC and SA only:

direct mid x, direct mid y, bottom height z, width x, width y, height from bottom height to top, 
rotation
