A world unit is the basic unit of measure when dealing with BZFlag. World units have no real-world counterpart, as they are a purely virtual concept, but they can be though of to be equivalent to about 1 meter in length if you assume a roughly real world sized tank.
All coordinates in the map file are specified in World Units. Many Server Variables are specified in terms of world units or world units per second as well.
Contents
Origin[edit]
The origin for the World coordinate system is the center of the map.
Orientation[edit]
World Units are oriented in a normal right hand rule coordinate system with positive Z being the "UP" direction.
North[edit]
"north" on the in game radar is the positive Y direction in map coordinates.
Figure 1[edit]
This image shows a typical map, with the origin and axis directions clearly marked out.
Some useful measures at default settings[edit]

Calculating jump height[edit]
Jump height is determined by the gravity and jump velocity settings on the server (see Server Variables for details). Note that the jump velocity and gravity may be altered by flags like Wings.
- Max jump height = -(_jumpVelocity)2 / (2 * (_gravity))
A typical BZFlag player can reliably jump a bit more than 90% of the maximum jump height.
