Module tick 

TickClock: real time turned into fixed simulation steps (ADR-0003 §2): 60 a second, at most 4 in one frame, after which the game slows down rather than spiral. Whole nanoseconds, so it counts the same on every machine.

Structs

TickClock

The time a frame brings, turned into fixed steps; what is left of a step waits for the next frame.

Constants

MAX_STEPS

The most steps one frame runs: a frame later than this drops the rest of its time.

STEPS_PER_SECOND

Fixed simulation steps a second: shuyi_core::timer::STEPS_PER_SECOND.
