Scripts for beginners.

There are no scripts for this, but you can try another method: copy the file data/GameMechanics/MoonCalendar/Default into your map. It will contain lines like this:

    WEEK_OF_PLAGUE
    WEEK_OF_IDLENESS
    WEEK_OF_TREANT
    WEEK_OF_TOAD
    WEEK_OF_MAGIC

Change the very first entry to WEEK_OF_GOLD. Then, in the editor, set the map property RandomMoons to false. The downside is that all weeks will become non-random and will follow the sequence from the specified file.
