LINK

LINK is a CAOS command introduced in Creatures 3 which is used to help smells travel between different levels of a metaroom, and through doors. It is primarily used by metaroom developers as part of creating a metaroom. As early metaroom developers may not have built in this functionality, Amaikokonut developed a Magic Words module (Magic Words Room Edits) that lets players easily add this ability for smells to travel between floors and across doors.

The tutorials Using the Map Editor part 1 and Creating a Metaroom part 6 discuss the use of the LINK command in greater detail.
