Frame callbacks are user-defined JavaScript functions that run on every single game "frame update".
Overview
These are faster than timers, which only fire 4 times a second. See Oolite JavaScript Reference: Timer for more on those.
Frame callbacks can be used for a number of purposes including animations
"shift-F" - Displays frame rate, object- and collision-counter and player's pwm-coordinates. (Only available in "Developer Release" versions of Oolite.)
