$bbox是一个QC 命令(en)，可在所有的 起源 游戏中使用。 It defines an axis-aligned bounding box(en) used by the Category:AI(en) to detect collisions with the world, mostly for movement purposes.

Models will be culled (hidden) when the bounding box is no longer in the players field of view, as a means to optimize the game. Too small bounding boxes can cause a model to disappear before it really left the FOV(en).

This is also called the hull.

$bbox lines are automatically generated when compiling a model(en), as long as there are no lines existing already.

Syntax

$bbox	(min x) (min y) (min z) (max x) (max y) (max z)
