The group object allows a map-maker to bring together a number of elements and refer to them as a single object. The group of elements is created in the define object and then called by name with the group object. The group of elements can then be placed, copied, and/or modified as a whole instead of having to re-create separate objects. Group creates an "instance" of something defined.
Unlike most other objects, the group object can come before the definition in the bzw file. This may help make the bzw file more readable.

The valid parameters for groups are:
|shift||Shift the group (repeatable).|
|scale||Scale the group (repeatable).|
|rotation||Rotate the group (in degrees).|
|shear||Shear the group (repeatable).|
|spin||Spin the group (repeatable).|
|team||Redefine all base colors within group.|
|tint||Hierarchically tints objects within group.|
|drivethrough||Make all objects in group drivethrough.|
|shootthrough||Make all objects in the group shootthrough.|
|phydrv||Apply physics to all objects/faces within group.|
|matref||Apply material to all objects/faces within group.|

There are currently no supported editors: groups are normally most useful when editing by hand.
The group definition object was added with the v2.0.0 release of BZFlag.
