Item placement files, known by the extension .ipl, are map files used to place objects into the GTA world, as well as define zones, paths, garages, interior portals, and a lot more. Most IPL files can easily be opened and edited using any text-editing program like Notepad. In San Andreas there are also binary IPL files which are located in the IMG archives of the game. Those you can only open using a special editor.

Structure

The .ipl files are split up into many sections. Not all of them have to be used, leaving them empty works as well. Each section starts with a section identifier and ends with the keyword "end", both in a separate line.

Example:

inst
...
end

PATH

Vice City only

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.
