Mission Filestructure

Choosing a PK4 filename

It's important to come up with a unique filename for your PK4 file, as the filename is used by the in-game mission manager to distinguish the packages: it's best to choose a PK4 name that has not been used by other released missions. Furthermore, don't use foreign characters for the filename, stick with the alphanumeric characters A-Z, a-z and 0-9. Please do not include version information in the filename, future updates should have the same filename to properly update via the in-game installer. ../darkmod/fms/levelname.pk4 //path

Mission PK4s

Each TDM mission must be packaged in a PK4 file (a PK4 is just a renamed ZIP archive). The PK4 contains all the files needed to run the mission, including map, cm, aas, proc files, textures, models, scripts, defs, xdata, etc. The contents of the PK4 resemble the folder structure as found in the main darkmod/ directory: textures go into textures/, .def files go to def/ and so on.

Mimimum content of a pk4

At the very minimum, a PK4 archive needs to contain the compiled map and two text files:

maps/outpost.map
maps/outpost.proc
maps/outpost.cm
maps/outpost.aas32
darkmod.txt
startingmap.txt

Easy to see, the above example list of files is based on a mission called outpost. The two text files are needed to display your mission in the "New Mission" dialog in TDM's main menu. See their description below.
