# Ticker

Ticker class

Hooks into the scheduler’s scheduleFrameCallback() mechanism to invoke a callback every tick.

• Can be started and stopped.
• Each tick, the Ticker provides the callback with the duration since the first tick after it was started.
• Because tickers always give their elapsed time relative to the first tick after they were started, tickers are all synchronised.
