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 of door
Type
type of garage
Name
used to edit garage through the SCM

Grge Door Types

ID Description
1 door rotates up and away from garage front
2 door rolls straight up and down

Grge Garage 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
entrance location
ROT
 ???
R1
X radius of entry
R2
Y radius of entry
C8
constant 8
X2, Y2, Z2
exit location
Rot2
exit rotation in degrees
Int
The target interior number
Mark
The type of marker
Name
interior name, used to find the counterpart and to identify via mission script
Sky
Sky color changer
I2
unknown integer flags, could be weather related
Time On
enables the marker at this time
Time Off
disables the marker at this time
