Tag

This article or section is a stub. Please help the Doom Wiki by adding to it.

Behaviour in doom is controlled by using a combination of tags and types applied to linedefs and sectors. Tags are used to relate an action, as specified by a linedef type, to the sector which it will affect.

Normally, a tag is an arbitrary non-zero integer, specified in the tag field of linedef and sector entries.

The Boom engine greatly extended the number of sector and linedef types, as well as introducing behaviours that involve Things.
