The sphere is a BZW Object that defines a sphere in the game arena.


The code to place a sphere in your map is as follows:

 name example_sphere
 divisions 4
 position 0 0 10
 size 10 10 10
 radius 10
 rotation 0
 shift 0 0 0
 scale 0 0 0
 shear 0 0 0
 spin angle nx ny nz
 phydrv example_phydrv
 matref example_material

Valid properites for a sphere are

name defines the name of the sphere, it is not required, and often unused
divisions defines the number of subdivisions (pieces) of the sphere
flatshading enables flat shading, smooth shading is the default
position defines the center point of the sphere
size defines the size of the sphere
radius sets all size values to the same value
rotation defines rotation for the sphere
shift shifts the sphere (repeatable)
scale scales the sphere (repeatable)
shear shears the sphere (repeatable)
spin spins the sphere around vector n (repeatable)
phydrv attaches a physics driver to the sphere
smoothbounce makes ricochets use normals
matref defines a material for the sphere to use


By default, the sphere is a perfect sphere, with a red brick texture around the outside. You can, however, make the sphere elongated on one side (just don't use the radius option).


The sphere object has been supported since BZFlag 2.0.0. In previous versions of BZFlag, this object will not work.

Editor Support

Editors that support the sphere object include Blender using the BZWTools, Wings3D using the BZW Exporter for Wings3D, and pyBZEdit. BZEdit and BZFed do NOT support the sphere.
