A Box is a BZW map structure that defines a rectilinear parallelepiped in the world.


Default boxes in 3.0

The code for a box object is as follows

 position 10 20 30
 rotation 45
 size 1 2 3

Valid parameters for a box are

defines the center of the box in X and Y and the bottom of the box in Z.
defines a rotation around the Z axis for the box, in degrees.
defines the distance from the center to the side of the box in X and Y, and the total height of the box in Z.

In versions 2.0.8 and older, boxes do not support material, custom textures, or physics drivers. The meshbox object replaces the box object and supports all these features and capabilities.

However, as of June 6, 2006 (SVN revision 13013, version 2.0.9), bzfs will convert the box object to a mesh when necessary. This feature allows them to be textured and have physics drivers assigned to them.

More information that needs to be merged into the wiki, as well as the BZW manfile: Smart Boxes and Pyramids


Box objects by default have a red brick texture on the vertical sides, and a white plaster texture on the top and bottom. A box of height 0 on ground level is visible.

The texsizes of boxes and boxes made of meshes (e.g. meshbox and box with one of the new properties) can be different. The size depends on the chosen display quality setting in the options menu.

Box type texsize with quality setting experimental in 2.0.x and high in 2.99
box (old style box) -2.0f -2.0f -8.0f -8.0f
meshbox -8.0f -8.0f -8.0f -8.0f
box with one meshbox property -8.0f -8.0f -8.0f -8.0f
Box type texsize with lower quality setting than in the above table
box (old style box) -2.0f -2.0f -8.0f -8.0f
meshbox -2.0f -2.0f -8.0f -8.0f
box with one meshbox property -2.0f -2.0f -8.0f -8.0f

This will cause the textures to scale differently for some players in X and Z axis. This can not be solved by adjusting the texsizes in map. The advice is not to mix old style boxes, meshboxes and boxes with one meshbox property, all in the same map.

In BZFlag 3.0 quality level experimental will become the new level high.


The box is one of the original objects supported by BZFlag and has been a mainstay of maps since the very beginning. Boxes are heavily used by the software when generating random maps. In v2.0.0 the box was replaced with the meshbox object to support Materials and Physics Drivers. The original box definition was left unchanged, in order to maintain functional compatibility for older maps.

The box object is supported by all known editors.
