The arc object is a BZW object that defines an arc or cylinder in the game arena.

Code[edit]

Appearance of an arc with solid color materials. The words show the names used to map materials to various sides. Obviously, the bottom matref is not shown.

To place an arc into your map file, the following template is suggested:

arc
 name example_arc
 divisions 16
 flatshading
 angle 360
 ratio 1
 position 0 0 0
 rotation 0
 size 10 10 10
 shift 0 0 0
 shear 0 0 0
 scale 1 1 1
 spin angle nx ny nz
 texsize -2.0 -2.0 -8.0 -8.0
 phydrv physics_driver_name
 smoothbounce
 
 ## You can give the entire arc a single material with the lone 'matref' property, 
 ## or you can give different parts different materials, as shown below
 matref material0
 top matref material1
 bottom matref material2
 inside matref material3
 outside matref material4
 startside matref material5
 endside matref material6
end

Valid parameters for an arc are:

Parameter Description
name defines the name of arc, often unused.
divisions defines the number of subdivisions in the arc.
flatshading defines the use of flat shading, smooth is the default.
angle defines the sweep of the arc, 360 indicates a full circle.
ratio defines the ratio to make a hollow arc, the parameter is (outrad - inrad) / outrad.
position defines the position of the arc in X-pos, Y-pos and the height of the arc in Z.
rotation defines a rotation around the Z axis for the arc, in degrees.
size defines the distance from the center to the side of the arc in X and Y, and the total height of the arc in Z.
shift shift the arc (repeatable).
shear (repeatable).
scale defines the scale of the arc in x,y, and z, 1 is the default, lower values make it smaller (repeatable).
spin angle rotate the arc around a vector by angle. ONE of nx, ny, and nz should be 1, the others should be 0. (repeatable).
texsize texture sizes, changes how the textures scale on the object. In 2.4.x standard boxes have "texsize -2.0 -2.0 -8.0 -8.0".
phydrv reference to a predefined physics driver.
smoothbounce defines that shot bounces use normals.
matref reference to a predefined material.

Appearance[edit]

The arc, by default, has the red brick wall texture on the sides, and the grey roof appearance of a normal box on the top. However, using matref one can change the appearance of the arc.

History[edit]

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

Editor Support[edit]

Editors that support the arc object include Blender using the BZWTools, Wings3D, and pyBZEdit. BZEdit and BZFed do NOT support the arcs.
