Accessors

publiccomplete

• get complete(): boolean

• Returns boolean

publicisRunning

• get isRunning(): boolean

• Returns boolean

publictimeElapsedTowardNextAction

• get timeElapsedTowardNextAction(): number

• ---

  Returns number

  milliseconds elapsed toward the next action

publictimeToNextAction

• get timeToNextAction(): number

• ---

  Returns number

  milliseconds until the next action callback, if complete will return 0

publictimesRepeated

• get timesRepeated(): number

• Returns number

Methods

publiccancel

• cancel(): void

• Cancels the timer, preventing any further executions.

  ---

  Returns void

publicgetTimeRunning

• getTimeRunning(): number

• Returns number

publicoff

• off(fcn: () => void): void

• Removes a callback from the callback list to be fired after the interval is complete.

  ---

  Parameters

  • fcn: () => void

    The callback to be removed from the callback list, to be fired after the interval is complete.

  Returns void

publicon

• on(fcn: () => void): void

• Adds a new callback to be fired after the interval is complete

  ---

  Parameters

  • fcn: () => void

    The callback to be added to the callback list, to be fired after the interval is complete.

  Returns void

publicpause

• pause(): Timer

• Pauses the timer, time will no longer increment towards the next call

  ---

  Returns Timer

publicreset

• reset(newInterval?: number, newNumberOfRepeats?: number): void

• Resets the timer so that it can be reused, and optionally reconfigure the timers interval.

  Warning** you may need to call timer.start() again if the timer had completed

  ---

  Parameters

  • optionalnewInterval: number

    If specified, sets a new non-negative interval in milliseconds to refire the callback

  • optionalnewNumberOfRepeats: number

    If specified, sets a new non-negative upper limit to the number of time this timer executes

  Returns void

publicresume

• resume(): Timer

• Resumes the timer, time will now increment towards the next call.

  ---

  Returns Timer

publicstart

• start(): Timer

• Starts the timer, if the timer was complete it will restart the timer and reset the elapsed time counter

  ---

  Returns Timer

publicstop

• stop(): Timer

• Stops the timer and resets the elapsed time counter towards the next action invocation

  ---

  Returns Timer

publicupdate

• update(delta: number): void

• Updates the timer after a certain number of milliseconds have elapsed. This is used internally by the engine.

  ---

  Parameters

  • delta: number

    Number of elapsed milliseconds since the last update.

  Returns void
