Item Placement

Introduction

Item PLacement (.ipl) files are used to place objects into gta world, this includes objects, zones and paths.

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

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, Effect, Vx, Vy, Vz, Cm

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

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

FrontX, Y

lower right front

Flag

type of garage

Name

used to edit garage through the SCM

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
