Tag extensions

Ringworld reads a few tag fields that the stock engine does not have. Most of them sit in space that stock tags leave unused, so existing tags keep working and read as the stock behavior.

Note

The stock editing kit does not show these fields. They can be set with invader-edit from Invader, using tag definitions that include them.

New tag groups

Ringworld maps

Maps built with ringtool are marked as Ringworld maps in their header. Features that read data other map compilers cannot write are limited to those maps.
