Module:Item2/core

Module documentation[view] [edit] [history] [purge]

This module depends on the following other modules:

• Module:Util
• Module:Cargo
• Module:Game
• Module:Item2/config

This submodule contains core configuration and functions for use in Module:Item2 and its other submodules.

The above documentation is transcluded from Module:Item2/core/doc. (edit | history)
Editors can experiment in this module's sandbox (edit | diff) and testcases (create) pages.
