Name Type Description
game Phaser.Game

A reference to the currently running Game.

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:
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:
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:
Returns:

Itself.

Type
Phaser.Tween

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

Sets this tween to be a from tween on the properties given. A from tween starts at the given value and tweens to the current values. For example a Sprite with an x coordinate of 100 could be tweened from x: 200 by giving a properties object of { x: 200 }.

Parameters:
Name Type Argument Default Description
properties object

Properties you want to tween from.

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 number <optional>
0

Should the tween automatically restart once complete? If you want it to run forever set as Number.MAX_VALUE. This ignores any chained tweens.

yoyo boolean <optional>
false

A tween that yoyos will reverse itself and play backwards automatically. A yoyo'd tween doesn't fire the Tween.onComplete event, so listen for Tween.onLoop instead.

Source:
Returns:

This Tween object.

Type
Phaser.Tween

generateData(frameRate, data) → {array}

This will generate an array populated with the tweened object values from start to end. It works by running the tween simulation at the given frame rate based on the values set-up in Tween.to and similar functions. It ignores delay and repeat counts and any chained tweens. Just one play through of tween data is returned, including yoyo if set.

Parameters:
Name Type Argument Default Description
frameRate number <optional>
60

The speed in frames per second that the data should be generated at. The higher the value, the larger the array it creates.

data array <optional>

If given the generated data will be appended to this array, otherwise a new array will be returned.

Source:
Returns:

An array of tweened values.

Type
array

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:
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:
Returns:

Itself.

Type
Phaser.Tween

onUpdateCallback(callback, callbackContext) → {Phaser.Tween}

Sets a callback to be fired each time this tween updates.

Parameters:
Name Type Description
callback function

The callback to invoke each time this tween is updated.

callbackContext object

The context in which to call the onUpdate callback.

Source:
Returns:

Itself.

Type
Phaser.Tween

pause()

Pauses the tween.

Source:

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:
Returns:

Itself.

Type
Phaser.Tween

resume()

Resumes a paused tween.

Source:

start() → {Phaser.Tween}

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

Source:
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:
Returns:

Itself.

Type
Phaser.Tween

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

Sets this tween to be a to tween on the properties given. A to tween starts at the current value and tweens to the destination value given. For example a Sprite with an x coordinate of 100 could be tweened to x 200 by giving a properties object of { x: 200 }.

Parameters:
Name Type Argument Default Description
properties object

The properties you want to tween, such as Sprite.x or Sound.volume. Given as a JavaScript object.

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 number <optional>
0

Should the tween automatically restart once complete? If you want it to run forever set as Number.MAX_VALUE. This ignores any chained tweens.

yoyo boolean <optional>
false

A tween that yoyos will reverse itself and play backwards automatically. A yoyo'd tween doesn't fire the Tween.onComplete event, so listen for Tween.onLoop instead.

Source:
Returns:

This Tween object.

Type
Phaser.Tween

update(time) → {boolean}

Core tween update function called by the TweenManager. Does not need to be invoked directly.

Parameters:
Name Type Description
time number

A timestamp passed in by the TweenManager.

Source:
Returns:

false if the tween has completed and should be deleted from the manager, otherwise true (still active).

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:
Returns:

Itself.
