manager :Phaser.TweenManager

Reference to the TweenManager responsible for updating this Tween.

Source - tween/Tween.js, line 35

onChildComplete :Phaser.Signal

The onChildComplete event is fired when the Tween or any of its children completes. Fires every time a child completes unless a child is set to repeat forever. It will be sent 2 parameters: the target object and this tween.

Source - tween/Tween.js, line 99

onComplete :Phaser.Signal

The onComplete event is fired when the Tween and all of its children completes. Does not fire if the Tween is set to loop or repeatAll(-1). It will be sent 2 parameters: the target object and this tween.

Source - tween/Tween.js, line 106

onLoop :Phaser.Signal

The onLoop event is fired if the Tween or any child tween loops. It will be sent 2 parameters: the target object and this tween.

Source - tween/Tween.js, line 84

onRepeat :Phaser.Signal

The onRepeat event is fired if the Tween and all of its children repeats. If this tween has no children this will never be fired. It will be sent 2 parameters: the target object and this tween.

Source - tween/Tween.js, line 91

onStart :Phaser.Signal

The onStart event is fired when the Tween begins. If there is a delay before the tween starts then onStart fires after the delay is finished. It will be sent 2 parameters: the target object and this tween.

Source - tween/Tween.js, line 77

Gets the total duration of this Tween, including all child tweens, in milliseconds.

Source - tween/Tween.js, line 878

Methods

chain(tweens) → {Phaser.Tween}

This method allows you to chain tweens together. Any tween chained to this tween will have its Tween.start method called as soon as this tween completes. If this tween never completes (i.e. repeatAll or loop is set) then the chain will never progress. Note that Tween.onComplete will fire when this tween completes, not when the whole chain completes. For that you should listen to onComplete on the final tween in your chain.

If you pass multiple tweens to this method they will be joined into a single long chain. For example if this is Tween A and you pass in B, C and D then B will be chained to A, C will be chained to B and D will be chained to C. Any previously chained tweens that may have been set will be overwritten.

Parameters:

Name	Type	Argument	Description
tweens	Phaser.Tween	<repeatable>	One or more tweens that will be chained to this one.

Returns:

Phaser.Tween -

This tween. Useful for method chaining.

Source - tween/Tween.js, line 549

delay(duration, index) → {Phaser.Tween}

Sets the delay in milliseconds before this tween will start. If there are child tweens it sets the delay before the first child starts. The delay is invoked as soon as you call Tween.start. If the tween is already running this method doesn't do anything for the current active tween. If you have not yet called Tween.to or Tween.from at least once then this method will do nothing, as there are no tweens to delay. If you have child tweens and pass -1 as the index value it sets the delay across all of them.

Parameters:

Name	Type	Argument	Default	Description
duration	number			The amount of time in ms that the Tween should wait until it begins once started is called. Set to zero to remove any active delay.
index	number	<optional>	0	If this tween has more than one child this allows you to target a specific child. If set to -1 it will set the delay on all the children.

Returns:

Phaser.Tween -

This tween. Useful for method chaining.

Source - tween/Tween.js, line 390

easing(ease, index) → {Phaser.Tween}

Set easing function this tween will use, i.e. Phaser.Easing.Linear.None. The ease function allows you define the rate of change. You can pass either a function such as Phaser.Easing.Circular.Out or a string such as "Circ". ".easeIn", ".easeOut" and "easeInOut" variants are all supported for all ease types. If you have child tweens and pass -1 as the index value it sets the easing function defined here across all of them.

Parameters:

Name	Type	Argument	Default	Description
ease	function | string			The easing function this tween will use, i.e. Phaser.Easing.Linear.None.
index	number	<optional>	0	If this tween has more than one child this allows you to target a specific child. If set to -1 it will set the easing function on all children.

Returns:

Phaser.Tween -

This tween. Useful for method chaining.

Source - tween/Tween.js, line 486

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 sets the target to the destination value and tweens to its current value. For example a Sprite with an x coordinate of 100 tweened from x 500 would be set to x 500 and then tweened to x 100 by giving a properties object of { x: 500 }. The ease function allows you define the rate of change. You can pass either a function such as Phaser.Easing.Circular.Out or a string such as "Circ". ".easeIn", ".easeOut" and "easeInOut" variants are all supported for all ease types.

Parameters:

Name	Type	Argument	Default	Description
properties	object			An object containing 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 | string	<optional>	null	Easing function. If not set it will default to Phaser.Easing.Default, which is Phaser.Easing.Linear.None by default but can be over-ridden.
autoStart	boolean	<optional>	false	Set to true to allow this tween to start automatically. Otherwise call Tween.start().
delay	number	<optional>	0	Delay before this tween will start in milliseconds. Defaults to 0, no delay.
repeat	number	<optional>	0	Should the tween automatically restart once complete? If you want it to run forever set as -1. This only effects this induvidual tween, not 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.

Returns:

Phaser.Tween -

This Tween object.

Source - tween/Tween.js, line 220

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 Tween.from. It ignores delay and repeat counts and any chained tweens, but does include child tweens. Just one play through of the 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.

Returns:

array -

An array of tweened values.

Source - tween/Tween.js, line 820

interpolation(interpolation, context, index) → {Phaser.Tween}

Sets the interpolation function the tween will use. By default it uses Phaser.Math.linearInterpolation. Also available: Phaser.Math.bezierInterpolation and Phaser.Math.catmullRomInterpolation. The interpolation function is only used if the target properties is an array. If you have child tweens and pass -1 as the index value and it will set the interpolation function across all of them.

Parameters:

Name	Type	Argument	Default	Description
interpolation	function			The interpolation function to use (Phaser.Math.linearInterpolation by default)
context	object	<optional>		The context under which the interpolation function will be run.
index	number	<optional>	0	If this tween has more than one child this allows you to target a specific child. If set to -1 it will set the interpolation function on all children.

Returns:

Phaser.Tween -

This tween. Useful for method chaining.

Source - tween/Tween.js, line 508

loop(value) → {Phaser.Tween}

Enables the looping of this tween and all child tweens. If this tween has no children this setting has no effect. If value is true then this is the same as setting Tween.repeatAll(-1). If value is false it is the same as setting Tween.repeatAll(0) and will reset the repeatCounter to zero.

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();

Parameters:

Name	Type	Argument	Default	Description
value	boolean	<optional>	true	If true this tween and any child tweens will loop once they reach the end. Set to false to remove an active loop.

Returns:

Phaser.Tween -

This tween. Useful for method chaining.

Source - tween/Tween.js, line 583

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. Set to null to remove an already active callback.
callbackContext	object	The context in which to call the onUpdate callback.

Returns:

Phaser.Tween -

This tween. Useful for method chaining.

Source - tween/Tween.js, line 615

pause()

Pauses the tween. Resume playback with Tween.resume.

Source - tween/Tween.js, line 632

repeat(total, repeat, index) → {Phaser.Tween}

Sets the number of times this tween will repeat. If you have not yet called Tween.to or Tween.from at least once then this method will do nothing, as there are no tweens to repeat. If you have child tweens and pass -1 as the index value it sets the number of times they'll repeat across all of them. If you wish to define how many times this Tween and all children will repeat see Tween.repeatAll.

Parameters:

Name	Type	Argument	Default	Description
total	number			How many times a tween should repeat before completing. Set to zero to remove an active repeat. Set to -1 to repeat forever.
repeat	number	<optional>	0	This is the amount of time to pause (in ms) before the repeat will start.
index	number	<optional>	0	If this tween has more than one child this allows you to target a specific child. If set to -1 it will set the repeat value on all the children.

Returns:

Phaser.Tween -

This tween. Useful for method chaining.

Source - tween/Tween.js, line 407

repeat(total) → {Phaser.Tween}

Set how many times this tween and all of its children will repeat. A tween (A) with 3 children (B,C,D) with a repeatAll value of 2 would play as: ABCDABCD before completing. When all child tweens have completed Tween.onLoop will be dispatched.

Parameters:

Name	Type	Description
total	number	How many times this tween and all children should repeat before completing. Set to zero to remove an active repeat. Set to -1 to repeat forever.

Returns:

Phaser.Tween -

This tween. Useful for method chaining.

Source - tween/Tween.js, line 530

repeatDelay(duration, index) → {Phaser.Tween}

Sets the delay in milliseconds before this tween will repeat itself. The repeatDelay is invoked as soon as you call Tween.start. If the tween is already running this method doesn't do anything for the current active tween. If you have not yet called Tween.to or Tween.from at least once then this method will do nothing, as there are no tweens to set repeatDelay on. If you have child tweens and pass -1 as the index value it sets the repeatDelay across all of them.

Parameters:

Name	Type	Argument	Default	Description
duration	number			The amount of time in ms that the Tween should wait until it repeats or yoyos once start is called. Set to zero to remove any active repeatDelay.
index	number	<optional>	0	If this tween has more than one child this allows you to target a specific child. If set to -1 it will set the repeatDelay on all the children.

Returns:

Phaser.Tween -

This tween. Useful for method chaining.

Source - tween/Tween.js, line 429

resume()

Resumes a paused tween.

Source - tween/Tween.js, line 664

start(index) → {Phaser.Tween}

Starts the tween running. Can also be called by the autoStart parameter of Tween.to or Tween.from. This sets the Tween.isRunning property to true and dispatches a Tween.onStart signal. If the Tween has a delay set then nothing will start tweening until the delay has expired.

Parameters:

Name	Type	Argument	Default	Description
index	number	<optional>	0	If this Tween contains child tweens you can specify which one to start from. The default is zero, i.e. the first tween created.

Returns:

Phaser.Tween -

This tween. Useful for method chaining.

Source - tween/Tween.js, line 267

stop(complete) → {Phaser.Tween}

Stops the tween if running and flags it for deletion from the TweenManager. If called directly the Tween.onComplete signal is not dispatched and no chained tweens are started unless the complete parameter is set to true. If you just wish to pause a tween then use Tween.pause instead.

Parameters:

Name	Type	Argument	Default	Description
complete	boolean	<optional>	false	Set to true to dispatch the Tween.onComplete signal.

Returns:

Phaser.Tween -

This tween. Useful for method chaining.

Source - tween/Tween.js, line 323

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 }. The ease function allows you define the rate of change. You can pass either a function such as Phaser.Easing.Circular.Out or a string such as "Circ". ".easeIn", ".easeOut" and "easeInOut" variants are all supported for all ease types.

Parameters:

Name	Type	Argument	Default	Description
properties	object			An object containing 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 | string	<optional>	null	Easing function. If not set it will default to Phaser.Easing.Default, which is Phaser.Easing.Linear.None by default but can be over-ridden.
autoStart	boolean	<optional>	false	Set to true to allow this tween to start automatically. Otherwise call Tween.start().
delay	number	<optional>	0	Delay before this tween will start in milliseconds. Defaults to 0, no delay.
repeat	number	<optional>	0	Should the tween automatically restart once complete? If you want it to run forever set as -1. This only effects this induvidual tween, not 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.

Returns:

Phaser.Tween -

This Tween object.

Source - tween/Tween.js, line 173

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.

Returns:

boolean -

false if the tween and all child tweens have completed and should be deleted from the manager, otherwise true (still active).

Source - tween/Tween.js, line 706

updateTweenData(property, value, index) → {Phaser.Tween}

Updates either a single TweenData or all TweenData objects properties to the given value. Used internally by methods like Tween.delay, Tween.yoyo, etc. but can also be called directly if you know which property you want to tweak. The property is not checked, so if you pass an invalid one you'll generate a run-time error.

Parameters:

Name	Type	Argument	Default	Description
property	string			The property to update.
value	number | function			The value to set the property to.
index	number	<optional>	0	If this tween has more than one child this allows you to target a specific child. If set to -1 it will set the delay on all the children.

Returns:

Phaser.Tween -

This tween. Useful for method chaining.

Source - tween/Tween.js, line 357

yoyo(enable, yoyoDelay, index) → {Phaser.Tween}

A Tween that has yoyo set to true will run through from its starting values to its end values and then play back in reverse from end to start. Used in combination with repeat you can create endless loops. If you have not yet called Tween.to or Tween.from at least once then this method will do nothing, as there are no tweens to yoyo. If you have child tweens and pass -1 as the index value it sets the yoyo property across all of them. If you wish to yoyo this Tween and all of its children then see Tween.yoyoAll.

Parameters:

Name	Type	Argument	Default	Description
enable	boolean			Set to true to yoyo this tween, or false to disable an already active yoyo.
yoyoDelay	number	<optional>	0	This is the amount of time to pause (in ms) before the yoyo will start.
index	number	<optional>	0	If this tween has more than one child this allows you to target a specific child. If set to -1 it will set yoyo on all the children.

Returns:

Phaser.Tween -

This tween. Useful for method chaining.

Source - tween/Tween.js, line 446

yoyoDelay(duration, index) → {Phaser.Tween}

Sets the delay in milliseconds before this tween will run a yoyo (only applies if yoyo is enabled). The repeatDelay is invoked as soon as you call Tween.start. If the tween is already running this method doesn't do anything for the current active tween. If you have not yet called Tween.to or Tween.from at least once then this method will do nothing, as there are no tweens to set repeatDelay on. If you have child tweens and pass -1 as the index value it sets the repeatDelay across all of them.

Parameters:

Name	Type	Argument	Default	Description
duration	number			The amount of time in ms that the Tween should wait until it repeats or yoyos once start is called. Set to zero to remove any active yoyoDelay.
index	number	<optional>	0	If this tween has more than one child this allows you to target a specific child. If set to -1 it will set the yoyoDelay on all the children.

Returns:

Phaser.Tween -

This tween. Useful for method chaining.
