Map Modding
.rpm files
RPM files are stores of static map content. They are a simple xml format. RPM files can be overriden from your mod folder.
The in-game map editor loads and saves the .rpm xml format.
In the following example only a single cell is merged with the existing contents of Joppa.RPM. If Load="Merge" is not supplied, the contents are replaced instead.
The in-game map editor doesn't support cutting a section of the map out for saving, so if you'd like to replace only a subsection you'll have to edit the .rpm by hand.
Example Joppa.RMP from Two Ctesiphus tutorial mod
<?xml version="1.0" encoding="utf-8"?> <Map Width="80" Height="25" Load="Merge"> <cell X="41" Y="7"> <object Name="Ctesiphus"></object> </cell> </Map>
