GetInterpolationFunction

<static> GetInterpolationFunction(interpolation)

Description:

This internal function is used to return the correct interpolation function for a Tween.

It can take a variety of input, including a string, or a custom function.

Parameters:

nametypeoptionaldescription
interpolationstring | functionnullNo

Returns: function - The interpolation function to use, or null.

GetNewValue

<static> GetNewValue(source, key, defaultValue)

Description:

Internal function used by the Tween Builder to create a function that will return the given value from the source.

Parameters:

nametypeoptionaldescription
sourceanyNoThe source object to get the value from.
keystringNoThe property to get from the source.
defaultValueanyNoA default value to return should the source not have the property set.

Returns: function - A function which, when called, will return the property value from the source.

Source: src/tweens/builders/GetNewValue.js - Line: 7
Since: 3.0.0

GetProps

<static> GetProps(config)

Description:

Internal function used by the Tween Builder to return an array of properties that the Tween will be operating on. It takes a tween configuration object and then checks that none of the props entries start with an underscore, or that none of the direct properties are on the Reserved list.

Parameters:

nametypeoptionaldescription
configPhaser.Types.Tweens.TweenBuilderConfigNoThe configuration object of the Tween to get the properties from.

Returns: Array.<string> - An array of all the properties the tween will operate on.

Source: src/tweens/builders/GetProps.js - Line: 9
Since: 3.0.0

GetTargets

<static> GetTargets(config)

Description:

Extracts an array of targets from a Tween configuration object.

The targets will be looked for in a targets property. If it's a function, its return value will be used as the result.

Parameters:

nametypeoptionaldescription
configobjectNoThe configuration object to use.

Returns: array - An array of targets (may contain only one element), or null if no targets were specified.

Source: src/tweens/builders/GetTargets.js - Line: 9
Since: 3.0.0

GetValueOp

<static> GetValueOp(key, propertyValue)

Description:

Returns getActive, getStart and getEnd functions for a TweenData based on a target property and end value.

getActive if not null, is invoked immediately as soon as the TweenData is running, and is set on the target property. getEnd is invoked once any start delays have expired and returns what the value should tween to. getStart is invoked when the tween reaches the end and needs to either repeat or yoyo, it returns the value to go back to.

If the end value is a number, it will be treated as an absolute value and the property will be tweened to it. A string can be provided to specify a relative end value which consists of an operation (+= to add to the current value, -= to subtract from the current value, *= to multiply the current value, or /= to divide the current value) followed by its operand.

A function can be provided to allow greater control over the end value; it will receive the target object being tweened, the name of the property being tweened, and the current value of the property as its arguments and must return a value.

If both the starting and the ending values need to be controlled, an object with getStart and getEnd callbacks, which will receive the same arguments, can be provided instead. If an object with a value property is provided, the property will be used as the effective value under the same rules described here.

Parameters:

nametypeoptionaldescription
keystringNoThe name of the property to modify.
propertyValue*NoThe ending value of the property, as described above.

Returns: function - An array of functions, getActive, getStart and getEnd, which return the starting and the ending value of the property based on the provided value.

NumberTweenBuilder

<static> NumberTweenBuilder(parent, config, defaults)

Description:

Creates a new Number Tween.

Parameters:

nametypeoptionaldescription
parentPhaser.Tweens.TweenManagerNoThe owner of the new Tween.
configPhaser.Types.Tweens.NumberTweenBuilderConfigNoConfiguration for the new Tween.
defaultsPhaser.Types.Tweens.TweenConfigDefaultsNoTween configuration defaults.

Returns: Phaser.Tweens.Tween - The new tween.

Since: 3.0.0

StaggerBuilder

<static> StaggerBuilder(value, [config])

Description:

Creates a Stagger function to be used by a Tween property.

The stagger function will allow you to stagger changes to the value of the property across all targets of the tween.

This is only worth using if the tween has multiple targets.

The following will stagger the delay by 100ms across all targets of the tween, causing them to scale down to 0.2 over the duration specified:

this.tweens.add({
    targets: [ ... ],
    scale: 0.2,
    ease: 'linear',
    duration: 1000,
    delay: this.tweens.stagger(100)
});

The following will stagger the delay by 500ms across all targets of the tween using a 10 x 6 grid, staggering from the center out, using a cubic ease.

this.tweens.add({
    targets: [ ... ],
    scale: 0.2,
    ease: 'linear',
    duration: 1000,
    delay: this.tweens.stagger(500, { grid: [ 10, 6 ], from: 'center', ease: 'cubic.out' })
});

Parameters:

nametypeoptionaldescription
valuenumber | Array.<number>NoThe amount to stagger by, or an array containing two elements representing the min and max values to stagger between.
configPhaser.Types.Tweens.StaggerConfigYesA Stagger Configuration object.

Returns: function - The stagger function.

<static> TweenBuilder(parent, config, defaults)

Description:

Creates a new Tween.

Parameters:

nametypeoptionaldescription
parentPhaser.Tweens.TweenManagerNoThe owner of the new Tween.
configPhaser.Types.Tweens.TweenBuilderConfig | objectNoConfiguration for the new Tween.
defaultsPhaser.Types.Tweens.TweenConfigDefaultsNoTween configuration defaults.

Returns: Phaser.Tweens.Tween - The new tween.

TweenChainBuilder

<static> TweenChainBuilder(parent, config)

Description:

Creates a new Tween Chain instance.

Parameters:

nametypeoptionaldescription
parentPhaser.Tweens.TweenManagerNoThe owner of the new Tween.
configPhaser.Types.Tweens.TweenChainBuilderConfig | objectNoConfiguration for the new Tween.

Returns: Phaser.Tweens.TweenChain - The new Tween Chain.
