Door

A Tremulous door is a sliding brush (or set of brushes, so very complex door shapes are easily possible). By default the door will automatically open when a player gets close to it. It does not rotate like the rotating door.

Doors are extremely flexible. For example: A door can easily be used as a lift (by setting lip to a high negative value). A door could also be very small, not intended for someone to walk through, to use it as a status light while, for example, a lift cycle is busy somewhere.
