Possible fix for .bzw manpage, http://my.bzflag.org/bzfman.cgi?bzw.5.in by a-delusion
Current manpage has texture matrix and material properties blended together, I separated them, and added the first ten lines of the material properties definition with a paste from http://manpage.willempen.org/5/bzw that's the only change I made.
Hopefully bold typeface survives multiple pastes.
DESCRIPTION
The BZFlag world file format describes a world environment that is used
by the BZFlag game server, bzfs. X BZW file format
The BZFlag world file format describes and environment that includes
the game map, physical world attributes, and automatic world weapons.
The map may contain a variety of "obstacles" like buildings, pyramids,
and meshes. These obstacles make up the world that the BZFlag tanks
will drive around in. Map attributes may be set to create worlds of
various sizes, the default size is 800x800.
Here is small example world:
# simple world containing a box, pyramid, and mesh
world
name Simple World
size 100.0
end
box
position -20 -20 0
size 10 20 10
end
pyramid
position 20 20 0
size 10 10 20
end
mesh
vertex -10 0 0
vertex 10 0 0
vertex 0 10 0
face
vertices 0 1 2
endface
end
The .bzw file is a plain text file with a relatively simple file for-
mat. The format of this text file consists of any number of objects
listed in any order (except that physics, textureMatrix, dynamicColor,
and material must come before they are referenced) separated by new-
lines and grouped into blocks of types. The list of world types con-
sists of:
world
options
waterLevel
dynamicColor
textureMatrix
material
physics
define
group
mesh
meshbox
on a following line, and a list of attributes for that object, one per
line, in between. The exceptions to the rule are define and face, which
are concluded with enddef and endface. Attributes may be listed in any
order. Attributes have default values, and if that is good enough, the
attribute need not be listed.
Words are always specified in lowercase. Line comments can be specified
by placing a # sign at the start of the line.
For documentation purposes, you can tag each object by adding a name
attribute. There is no set limit to the number of times you may use any
of the objects except for the world, options, and waterLevel objects,
they can only be specified once. The options object contains command
line arguments that are used to configure the server's game mode, but
can not contain server specific options such as -p, -passwd, and -conf.
In the following examples, the values are the defaults.
The World object
Header for the world.
world
name example_world
size 400.0
flagHeight 10.0
end
The Options object
A world file interface for setting command line options for BZFS.
options
-set _tankSpeed 36
-j +r -ms 3
+f GM{5} +f SW{5}
end
The Water Level object
Sets how high the water is, in a matter of units.
waterLevel
name example_waterlevel
height -1.0 # anything below 0 turns it off
end
The Group Definition object
Defines a group, which may include other group instances
This does not place any objects into the world, a group instance must
be used to generate world objects from a group definition.
define <example_groupdef>
group <example_groupdef> # a valid group definition reference
shift 0 0 0 # (repeatable)
scale 1 1 1 # (repeatable)
shear 0 0 0 # (repeatable)
spin angle nx ny nz # (repeatable)
# angle degrees about vector n
team 0 # change all base colors within group
tint 1 1 1 1 # hierarchically tints objects within this group
drivethrough # make all subobjects drivethrough
shootthrough # make all subobjects shootthrough
phydrv example_phydrv # reassign any valid physics drivers
matref example_material # set material properties
# (except for the color)
end
The Dynamic Color object
dynamicColor
name example_dyncol
# there are 4 channels that can be modified:
# red, green, blue, alpha
# there are 5 types of commands per channel:
# limits, sinusoid, clampUp, clampDown, sequence
# except for "limits" and "sequence", the commands are repeatable
# if a sequence is used, then clampUps and clampDowns have no effect
# sequences can use three states (0, 1, 2).
# 0 - equivalent to an active clampDown
# 1 - equivalent to active clampUp and clampDown
# 2 - equivalent to an active clampUp
# if both clampUp and clampDown are active, the value is (min+max)/2
# the sinusoid function starts at the max value
# the sum of a channel's sinusoids is clamped between 0 and 1
red limits 0 1 # min/max limits
green sinusoid 0.1 0 0.25 # period, offset, weight
blue clampUp 0.1 0 0.75 # period, offset, width
alpha clampDown 0.2 0.5 0.5 # period, offset, width
red sequence 0.0 0.0 0 2 1 1 2 0 ... # period, offset, list of states
end
The Texture Matrix object
textureMatrix
name example_texmat
scale 0.0 0.0 1.0 1.0 # u/v freqs, u/v scales
spin 0.0 # rotation freq
shift 0.0 0.0 # u/v freqs
center 0.5 0.5 # dynamic u/v center (for spin and scale)
fixedscale 0.0 0.0 # time invariant u/v scale
fixedspin 0.0 # time invariant rotation
fixedshift 0.0 0.0 # time invariant u/v shift
end
Material Properties
Material properties may be set on several types of objects, including
meshes, mesh faces, arcs, cones, spheres, and tetras. Here are the
properties:
material
name example_material
texture filename # set working texture (without PNG extension)
addtexture filename # add texture (without PNG extension)
notextures # specify that no textures are to be used
notexcolor # the color is not applied to the texture
notexalpha # don't use the texture's alpha channel
notexcolor # the color is not applied to the texture
# if a texture is specified, but not found, the default texture
# will be used. if the default texture is also not available, then
# the color will be used (untextured)
spheremap # use spherical texture coordinate mapping
texmat -1 # texture matrix (-1 for none)
dyncol -1 # dynamic color (-1 for none)
noradar # do not display on radar (except normal mode)
noshadow # do not render shadows
noculling # do not cull by face winding (double-sided)
nosorting # do not do front-to-back alpha sorting
nolighting # disable lighting
alphathresh 0.0 # alpha thresholding value
groupalpha # sort translucent faces as a group
occluder # faces with this material will occlude

# the 'death' property requires a non-blank message
end
The Mesh object

# of the mesh object. If the client is capable of using this data,
# then it is used to draw the mesh instead of the face information.

Adds a route to teleport a tank between two teleporters.
# Teleporter names are terminated with either :f (forward)
# or :b (backwards). The forwards link points to 0 degrees,
# and the backwards link points to 180. Links are made by
# pattern matching the teleporter names. The '*' and '?'
# globbing characters can be used to make multiple matches.
# If there are multiple matches for the "to" link, then the
# destination will be selected randomly between the matches.
# in-game.
# NOTE: bzfs -d -d -d -d will print the linkage table.

end
The Base object
Creates a team base where the corresponding team's flag is stored. The
oncap option will fire a world weapon of the specified type when the
The weapon can ether be timed or be event driven. Timed weapons should
use the initdelay and delay fields. Event driven weapons need to use
the trigger option to define what the trigger event is. Valid trigger
events are; OnCap, for flag capture events. OnSpawn, for player spawn
events. OnDie, for player death events. If the weapon is to be trig-
gered only for a specific team then the eventteam option should be used
with a team number ( 1 to 4 ). A eventteam value of -1 will trigger
this weapon for any team. -1 is the default eventteam value.
weapon
name example_weapon
position 0.0 0.0 0.0

has.

# dropped team flags will fly to the closest safety zone
safety 1 2 3 4
end
FILE SYNTAX
The symbol '?' mean that the item is optionnal.
The notation {a..b} mean that the number of times the item can be
present must be between 'a' and 'b', where '*' mean infinity. ('?' is
equivalent to {0..1})
