The frames per second at which this ticker is running.
The frames per second at which this ticker is running. The default is approximately 60 in most modern browsers. Note: This does not factor in the value of PIXI.ticker.Ticker#speed, which is specific to scaling PIXI.ticker.Ticker#deltaTime.
Calls module:eventemitter3.EventEmitter#on internally for the internal 'tick' event.
Calls module:eventemitter3.EventEmitter#on internally for the internal 'tick' event. It checks if the emitter has listeners, and if so it requests a new animation frame at this point.

Whether or not this ticker should invoke the method PIXI.ticker.Ticker#start automatically when a listener is added.
Scalar time value from last frame to this frame.
Scalar time value from last frame to this frame. This value is capped by setting PIXI.ticker.Ticker#minFPS and is scaled with PIXI.ticker.Ticker#speed. Note: The cap may be exceeded by scaling.
Time elapsed in milliseconds from last frame to this frame.
Time elapsed in milliseconds from last frame to this frame. Opposed to what the scalar PIXI.ticker.Ticker#deltaTime is based, this value is neither capped nor scaled. If the platform supports DOMHighResTimeStamp, this value will have a precision of 1 µs.
The last time PIXI.ticker.Ticker#update was invoked.
The last time PIXI.ticker.Ticker#update was invoked. This value is also reset internally outside of invoking update, but only when a new animation frame is requested. If the platform supports DOMHighResTimeStamp, this value will have a precision of 1 µs.
Manages the maximum amount of milliseconds allowed to elapse between invoking PIXI.ticker.Ticker#update.
Manages the maximum amount of milliseconds allowed to elapse between invoking PIXI.ticker.Ticker#update. This value is used to cap PIXI.ticker.Ticker#deltaTime, but does not effect the measured value of PIXI.ticker.Ticker#FPS. When setting this property it is clamped to a value between 0 and PIXI.TARGET_FPMS * 1000.
Calls module:eventemitter3.EventEmitter#off internally for 'tick' event.
Calls module:eventemitter3.EventEmitter#off internally for 'tick' event. It checks if the emitter has listeners for 'tick' event. If it does, then it cancels the animation frame.

Factor of current PIXI.ticker.Ticker#deltaTime.
Starts the ticker.
Starts the ticker. If the ticker has listeners a new animation frame is requested at this point.
Whether or not this ticker has been started.
Whether or not this ticker has been started. true if PIXI.ticker.Ticker#start has been called. false if PIXI.ticker.Ticker#stop has been called. While false, this value may change to true in the event of PIXI.ticker.Ticker#autoStart being true and a listener is added.
Stops the ticker.
Stops the ticker. If the ticker has requested an animation frame it is canceled at this point.
Triggers an update.
Triggers an update. An update entails setting the current PIXI.ticker.Ticker#elapsedMS, the current PIXI.ticker.Ticker#deltaTime, invoking all listeners with current deltaTime, and then finally setting PIXI.ticker.Ticker#lastTime with the value of currentTime that was provided. This method will be called automatically by animation frame callbacks if the ticker instance has been started and listeners are added.
the current time of execution (Type: Number/DOMHighResTimeStamp, Default: performance.now())
A Ticker class that runs an update loop that other objects listen to. This class is composed around an EventEmitter object to add listeners meant for execution on the next requested animation frame. Animation frames are requested only when necessary, e.g. When the ticker is started and the emitter has listeners.
