Timing events

For timing events, it's recommended to use the this.clock methods, from your Room instance.

Tip

All intervals and timeouts registered on this.clock are cleared automatically when the Room is disposed.

Important

The built-in setTimeout and setInterval methods rely on CPU load, which may delay an unexpected amount of time to execute.

Clock

Public methods

clock.setInterval(callback, time, ...args): Delayed

The setInterval() method repeatedly calls a function or executes a code snippet, with a fixed time delay between each call. It returns Delayed instance which identifies the interval, so you can manipulate it later.

clock.setTimeout(callback, time, ...args): Delayed

The setTimeout() method sets a timer which executes a function or specified piece of code once after the timer expires. It returns Delayed instance which identifies the interval, so you can manipulate it later.

clock.clear()

Clear all intervals and timeouts registered with clock.setInterval() and clock.setTimeout().

clock.start()

Start counting time.

clock.stop()

Stop counting time.

clock.tick()

This method is called automatically at every simulation interval step. All Delayed instances are checked during tick.

Tip

See Room#setSimiulationInterval() for more details.

Public properties

clock.elapsedTime

Elapsed time in milliseconds since clock.start() method was called. Read only.

clock.currentTime

Current time in milliseconds. Read only.

clock.deltaTime

The difference in milliseconds between the last and current clock.tick() call. Read only.

Delayed

Delayed instances are created from clock.setInterval() or clock.setTimeout() methods.

Public methods

delayed.clear()

Clears the timeout or interval.

delayed.reset()

Reset the elapsed time.

Public properties

delayed.active: boolean

Returns true if timer is still running.
