SubSpace works on its own special unit scales. This is a collection of observed units and other special physics that SubSpace uses.


Bounce Formula 
SpeedAfter = SpeedBefore * (16 / BounceFactor) (See Misc Settings.)
Rotation 
90° rotation in 1/100th of a second, ie: Set rotation to 400, can do a full rotation of 360° in one second.
In packets, rotation of a player's ship is a number 0-39... where 0 is straight up and proceeding clockwise. This corresponds to which of the 40 degree graphics to display.
degrees per tick = rotation_setting / 1000
Speed 
Pixels traveled in 10 seconds.
pixels per tick = speed_setting / 1000
Thrust 
Speed increased every 1/100th of a second.
Sample: Thrust of 10 applied for a second increases your speed by 1000
Tick 
1/100th of a second, i.e. 0.01s or 10ms.
Recharge 
Amount of energy units gained in 10 seconds.
Ball Friction 
The amount subtracted from a timer per tick. This timer is initialised to 1 million when the ball is fired, and multiplied with the ball x and y speeds separately on each tick. See also Ball Friction.
Gravity 
The amount of velocity applied per tick (thrust) is 1000*Gravity/(Distance^2) where Distance is the distance between the player and the Wormhole in pixels. GravityTopSpeed will be added to a player's top speed as long as at least one Wormhole is applying a thrust of 1 or more. The tile radius of the top speed effect is tiles=1.976*(g^.5).
