Methods

chain() → {Phaser.Tween}

You can chain tweens together by passing a reference to the chain function. This enables one tween to call another on completion. You can pass as many tweens as you like to this function, they will each be chained in sequence.

Source:

tween/Tween.js, line 383

Returns:

Itself.

Type: Phaser.Tween

delay(amount) → {Phaser.Tween}

Sets a delay time before this tween will start.

Parameters:

Name	Type	Description
`amount`	number	The amount of the delay in ms.

Source:

tween/Tween.js, line 311

Returns:

Itself.

Type: Phaser.Tween

easing(easing) → {Phaser.Tween}

Set easing function this tween will use, i.e. Phaser.Easing.Linear.None.

Parameters:

Name	Type	Description
`easing`	function	The easing function this tween will use, i.e. Phaser.Easing.Linear.None.

Source:

tween/Tween.js, line 354

Returns:

Itself.

Type: Phaser.Tween

interpolation(interpolation) → {Phaser.Tween}

Set interpolation function the tween will use, by default it uses Phaser.Math.linearInterpolation. Also available: Phaser.Math.bezierInterpolation and Phaser.Math.catmullRomInterpolation.

Parameters:

Name	Type	Description
`interpolation`	function	The interpolation function to use (Phaser.Math.linearInterpolation by default)

Source:

tween/Tween.js, line 368

Returns:

Itself.

Type: Phaser.Tween

loop() → {Phaser.Tween}

Loop a chain of tweens

Usage: game.add.tween(p).to({ x: 700 }, 1000, Phaser.Easing.Linear.None, true) .to({ y: 300 }, 1000, Phaser.Easing.Linear.None) .to({ x: 0 }, 1000, Phaser.Easing.Linear.None) .to({ y: 0 }, 1000, Phaser.Easing.Linear.None) .loop();

Source:

tween/Tween.js, line 397

Returns:

Itself.

Type: Phaser.Tween

onUpdateCallback(callback) → {Phaser.Tween}

Sets a callback to be fired each time this tween updates. Note: callback will be called in the context of the global scope.

Parameters:

Name	Type	Description
`callback`	function	The callback to invoke each time this tween is updated.

Source:

tween/Tween.js, line 416

Returns:

Itself.

Type: Phaser.Tween

pause()

Pauses the tween.

Source:

tween/Tween.js, line 432

repeat(times) → {Phaser.Tween}

Sets the number of times this tween will repeat.

Parameters:

Name	Type	Description
`times`	number	How many times to repeat.

Source:

tween/Tween.js, line 325

Returns:

Itself.

Type: Phaser.Tween

resume()

Resumes a paused tween.

Source:

tween/Tween.js, line 444

start() → {Phaser.Tween}

Starts the tween running. Can also be called by the autoStart parameter of Tween.to.

Source:

tween/Tween.js, line 243

Returns:

Itself.

Type: Phaser.Tween

stop() → {Phaser.Tween}

Stops the tween if running and removes it from the TweenManager. If there are any onComplete callbacks or events they are not dispatched.

Source:

tween/Tween.js, line 293

Returns:

Itself.

Type: Phaser.Tween

to(properties, duration, ease, autoStart, delay, repeat, yoyo) → {Phaser.Tween}

Configure the Tween

Parameters:

Name	Type	Argument	Default	Description
`properties`	object			Properties you want to tween.
`duration`	number	<optional>	1000	Duration of this tween in ms.
`ease`	function	<optional>	null	Easing function. If not set it will default to Phaser.Easing.Linear.None.
`autoStart`	boolean	<optional>	false	Whether this tween will start automatically or not.
`delay`	number	<optional>	0	Delay before this tween will start, defaults to 0 (no delay). Value given is in ms.
`repeat`	boolean	<optional>	0	Should the tween automatically restart once complete? (ignores any chained tweens).

Type: boolean

yoyo(yoyo) → {Phaser.Tween}

A tween that has yoyo set to true will run through from start to finish, then reverse from finish to start. Used in combination with repeat you can create endless loops.

Parameters:

Name	Type	Description
`yoyo`	boolean	Set to true to yoyo this tween.

Source:
