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.

Code

group my_group
  shift 0 0 0 
  scale 1 1 1
  rotation 0
  shear 0 0 0
  spin 0 0 0 0
  team 0
  tint 1 1 1 1
  drivethrough
  shootthrough
  phydrv my_phydrv
  matref my_material
end

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.

An in-depth explanation of the 3d-transformations of shift, scale, and shear can be found here

Editor Support

There are currently no supported editors: groups are normally most useful when editing by hand.

History

The group definition object was added with the v2.0.0 release of BZFlag.
