Tween

Phaser.Tweens.Tween

A Tween is able to manipulate the properties of one or more objects to any given value, based on a duration and type of ease. They are rarely instantiated directly and instead should be created via the TweenManager.

Please note that a Tween will not manipulate any property that begins with an underscore.

Public Members

callbacks

callbacks: Phaser.Types.Tweens.TweenCallbacks

Description:

An object containing the different Tween callback functions.

You can either set these in the Tween config, or by calling the Tween.setCallback method.

The types available are:

onActive - When the Tween is first created it moves to an 'active' state when added to the Tween Manager. 'Active' does not mean 'playing'. onStart - When the Tween starts playing after a delayed or paused state. This will happen at the same time as onActive if the tween has no delay and isn't paused. onLoop - When a Tween loops, if it has been set to do so. This happens after the loopDelay expires, if set. onComplete - When the Tween finishes playback fully. Never invoked if the Tween is set to repeat infinitely. onStop - Invoked only if the Tween.stop method is called. onPause - Invoked only if the Tween.pause method is called. Not invoked if the Tween Manager is paused. onResume - Invoked only if the Tween.resume method is called. Not invoked if the Tween Manager is resumed.

The following types are also available and are invoked on a TweenData level - that is per-object, per-property, being tweened.

onYoyo - When a TweenData starts a yoyo. This happens after the hold delay expires, if set. onRepeat - When a TweenData repeats playback. This happens after the repeatDelay expires, if set. onUpdate - When a TweenData updates a property on a source target during playback.

loop

loop: number

Description:

The number of times this Tween will loop.

Can be -1 for an infinite loop, zero for none, or a positive integer.

persist

persist: boolean

Description:

Will this Tween persist after playback? A Tween that persists will not be destroyed by the Tween Manager, or when calling Tween.stop, and can be re-played as required. You can either set this property when creating the tween in the tween config, or set it prior to playback.

However, it's up to you to ensure you destroy persistent tweens when you are finished with them, or they will retain references you may no longer require and waste memory.

By default, Tweens are set to not persist, so they are automatically cleaned-up by the Tween Manager.

reset

<instance> reset([skipInit])

Description:

Resets this Tween ready for another play-through.

This is called automatically from the Tween Manager, or from the parent TweenChain, and should not typically be invoked directly.

If you wish to restart this Tween, use the Tween.restart or Tween.seek methods instead.

Parameters:

name

type

optional

default

description

skipInit

boolean

Yes

false

Skip resetting the TweenData and Active State?

Returns: Phaser.Tweens.Tween - This Tween instance.

Fires: Phaser.Tweens.Events#event:TWEEN_ACTIVE

Source: src/tweens/tween/Tween.js#L586
Since: 3.60.0


restart

<instance> restart()

Description:

Restarts the Tween from the beginning.

If the Tween has already finished and been destroyed, restarting it will throw an error.

If you wish to restart the Tween from a specific point, use the Tween.seek method instead.

Returns: Phaser.Tweens.Tween - This Tween instance.

Source: src/tweens/tween/Tween.js#L313
Since: 3.0.0


resume

<instance> resume()

Description:

Resumes the playback of a previously paused Tween.

You can also toggle the Tween.paused boolean property, but doing so will not trigger the RESUME event.

Returns: Phaser.Tweens.Tween - This Tween instance.

Fires: Phaser.Tweens.Events#event:TWEEN_RESUME

Inherits: Phaser.Tweens.BaseTween#resume

Source: src/tweens/tween/BaseTween.js#L352
Since: 3.60.0


rewind

<instance> rewind(ms)

Description:

Moves this Tween backward by the given amount of milliseconds.

It will only rewind through the current loop of the Tween. For example, if the Tween is set to repeat or yoyo, it can only fast forward through a single section of the sequence. Use Tween.seek for more complex playhead control.

If the Tween is paused or has already finished, calling this will have no effect.

Parameters:

name

type

optional

description

ms

number

No

The number of milliseconds to rewind this Tween by.

Returns: Phaser.Tweens.Tween - This Tween instance.

Source: src/tweens/tween/Tween.js#L747
Since: 3.60.0


seek

<instance> seek([amount], [delta], [emit])

Description:

Seeks to a specific point in the Tween.

The given amount is a value in milliseconds that represents how far into the Tween you wish to seek, based on the start of the Tween.

Note that the seek amount takes the entire duration of the Tween into account, including delays, loops and repeats. For example, a Tween that lasts for 2 seconds, but that loops 3 times, would have a total duration of 6 seconds, so seeking to 3000 ms would seek to the Tweens half-way point based on its entire duration.

Prior to Phaser 3.60 this value was given as a number between 0 and 1 and didn't work for Tweens had an infinite repeat. This new method works for all Tweens.

Seeking works by resetting the Tween to its initial values and then iterating through the Tween at delta jumps per step. The longer the Tween, the longer this can take. If you need more precision you can reduce the delta value. If you need a faster seek, you can increase it. When the Tween is reset it will refresh the starting and ending values. If these are coming from a dynamic function, or a random array, it will be called for each seek.

While seeking the Tween will not emit any of its events or callbacks unless the 3rd parameter is set to true.

If this Tween is paused, seeking will not change this fact. It will advance the Tween to the desired point and then pause it again.

Parameters:

name

type

optional

default

description

amount

number

Yes

0

The number of milliseconds to seek into the Tween from the beginning.

delta

number

Yes

16.6

The size of each step when seeking through the Tween. A higher value completes faster but at the cost of less precision.

emit

boolean

Yes

false

While seeking, should the Tween emit any of its events or callbacks? The default is 'false', i.e. to seek silently.

Returns: Phaser.Tweens.Tween - This Tween instance.

setActiveState

<instance> setActiveState()

Description:

Since: 3.60.0


setCallback

<instance> setCallback(type, callback, [params])

Description:

Sets an event based callback to be invoked during playback.

Calling this method will replace a previously set callback for the given type, if any exists.

The types available are:

onActive - When the Tween is first created it moves to an 'active' state when added to the Tween Manager. 'Active' does not mean 'playing'. onStart - When the Tween starts playing after a delayed or paused state. This will happen at the same time as onActive if the tween has no delay and isn't paused. onLoop - When a Tween loops, if it has been set to do so. This happens after the loopDelay expires, if set. onComplete - When the Tween finishes playback fully. Never invoked if the Tween is set to repeat infinitely. onStop - Invoked only if the Tween.stop method is called. onPause - Invoked only if the Tween.pause method is called. Not invoked if the Tween Manager is paused. onResume - Invoked only if the Tween.resume method is called. Not invoked if the Tween Manager is resumed.

The following types are also available and are invoked on a TweenData level - that is per-object, per-property, being tweened.

onYoyo - When a TweenData starts a yoyo. This happens after the hold delay expires, if set. onRepeat - When a TweenData repeats playback. This happens after the repeatDelay expires, if set. onUpdate - When a TweenData updates a property on a source target during playback.

Parameters:

Source: src/events/EventEmitter.js#L31
Since: 3.0.0


stop

<instance> stop()

Description:

Stops the Tween immediately, whatever stage of progress it is at.

If not a part of a Tween Chain it is also flagged for removal by the Tween Manager.

If an onStop callback has been defined it will automatically invoke it.

The Tween will be removed during the next game frame, but should be considered 'destroyed' from this point on.

Typically, you cannot play a Tween that has been stopped. If you just wish to pause the tween, not destroy it, then call the pause method instead and use resume to continue playback. If you wish to restart the Tween, use the restart or seek methods.

Returns: Phaser.Tweens.Tween - This Tween instance.
