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.
Many Server Variables are specified in terms of world units or world units per second.
Some useful measures at default settings
Jump height limit (next to impossible) | See below | 18.42 |
Doable jump height | See below | 17.0 |
Tank length | _tankLength | 8.04 |
Tank width | _tankWidth | 2.8 |
Tank height | _tankHeight | 2.05 |
Barrel height | _muzzleHeight | 1.57 |
Drivable bump height | _bumpHeight | 0.33 |
Calculating jump height
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 including Low Gravity and 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.
