The Animation Manager.
Animations are managed by the global Animation Manager. This is a singleton class that is responsible for creating and delivering animations and their corresponding data to all Game Objects. Unlike plugins it is owned by the Game instance, not the Scene.
Sprites and other Game Objects get the data they need from the AnimationManager.

Adds a mix between two animations.
Mixing allows you to specify a unique delay between a pairing of animations.
When playing Animation A on a Game Object, if you then play Animation B, and a mix exists, it will wait for the specified delay to be over before playing Animation B.
This allows you to customise smoothing between different types of animation, such as blending between an idle and a walk state, or a running and a firing state.
Note that mixing is only applied if you use the Sprite.play
method. If you opt to use
playAfterRepeat
or playAfterDelay
instead, those will take priority and the mix
delay will not be used.
To update an existing mix, just call this method with the new delay.
To remove a mix pairing, see the removeMix
method.

This Animation Manager.
Registers event listeners after the Game boots.
Creates a new Animation and adds it to the Animation Manager.
Animations are global. Once created, you can use them in any Scene in your game. They are not Scene specific.
If an invalid key is given this method will return false
.
If you pass the key of an animation that already exists in the Animation Manager, that animation will be returned.
A brand new animation is only created if the key is valid and not already in use.
If you wish to re-use an existing key, call AnimationManager.remove
first, then this method.

Create one, or more animations from a loaded Aseprite JSON file.
Aseprite is a powerful animated sprite editor and pixel art tool.
You can find more details at https://www.aseprite.org/
To export a compatible JSON file in Aseprite, please do the following:
Go to "File - Export Sprite Sheet"
On the Layout tab: 2a. Set the "Sheet type" to "Packed" 2b. Set the "Constraints" to "None" 2c. Check the "Merge Duplicates" checkbox
On the Sprite tab: 3a. Set "Layers" to "Visible layers" 3b. Set "Frames" to "All frames", unless you only wish to export a sub-set of tags
On the Borders tab: 4a. Check the "Trim Sprite" and "Trim Cells" options 4b. Ensure "Border Padding", "Spacing" and "Inner Padding" are all > 0 (1 is usually enough)
On the Output tab: 5a. Check "Output File", give your image a name and make sure you choose "png files" as the file type 5b. Check "JSON Data" and give your json file a name 5c. The JSON Data type can be either a Hash or Array, Phaser doesn't mind. 5d. Make sure "Tags" is checked in the Meta options 5e. In the "Item Filename" input box, make sure it says just "{frame}" and nothing more.
Click export
This was tested with Aseprite 1.2.25.
This will export a png and json file which you can load using the Aseprite Loader, i.e.:
function preload ()
{
this.load.path = 'assets/animations/aseprite/';
this.load.aseprite('paladin', 'paladin.png', 'paladin.json');
}
Once loaded, you can call this method from within a Scene with the 'atlas' key:
this.anims.createFromAseprite('paladin');
Any animations defined in the JSON will now be available to use in Phaser and you play them via their Tag name. For example, if you have an animation called 'War Cry' on your Aseprite timeline, you can play it in Phaser using that Tag name:
this.add.sprite(400, 300).play('War Cry');
When calling this method you can optionally provide an array of tag names, and only those animations will be created. For example:
this.anims.createFromAseprite('paladin', [ 'step', 'War Cry', 'Magnum Break' ]);
This will only create the 3 animations defined. Note that the tag names are case-sensitive.

An array containing all of the Animation objects that were created as a result of this call.
Generate an array of Phaser.Types.Animations.AnimationFrame objects from a texture key and configuration object.
Generates objects with string based frame names, as configured by the given Phaser.Types.Animations.GenerateFrameNames.
It's a helper method, designed to make it easier for you to extract all of the frame names from texture atlases.
If you're working with a sprite sheet, see the generateFrameNumbers
method instead.
Example:
If you have a texture atlases loaded called gems
and it contains 6 frames called ruby_0001
, ruby_0002
, and so on,
then you can call this method using: this.anims.generateFrameNames('gems', { prefix: 'ruby_', start: 1, end: 6, zeroPad: 4 })
.
The end
value tells it to select frames 1 through 6, incrementally numbered, all starting with the prefix ruby_
. The zeroPad
value tells it how many zeroes pad out the numbers. To create an animation using this method, you can do:
this.anims.create({
key: 'ruby',
repeat: -1,
frames: this.anims.generateFrameNames('gems', {
prefix: 'ruby_',
end: 6,
zeroPad: 4
})
});
Please see the animation examples for further details.
name | type | arguments | description |
---|---|---|---|
key | string |
The key for the texture containing the animation frames. |

config | Phaser.Types.Animations.GenerateFrameNames | <optional> |
The configuration object for the animation frame names. |
The array of {@link Phaser.Types.Animations.AnimationFrame} objects.
Generate an array of Phaser.Types.Animations.AnimationFrame objects from a texture key and configuration object.
Generates objects with numbered frame names, as configured by the given Phaser.Types.Animations.GenerateFrameNumbers.
If you're working with a texture atlas, see the generateFrameNames
method instead.
It's a helper method, designed to make it easier for you to extract frames from sprite sheets.
Example:
If you have a sprite sheet loaded called explosion
and it contains 12 frames, then you can call this method using:
this.anims.generateFrameNumbers('explosion', { start: 0, end: 11 })
.
The end
value of 11 tells it to stop after the 12th frame has been added, because it started at zero.
To create an animation using this method, you can do:
this.anims.create({
key: 'boom',
frames: this.anims.generateFrameNumbers('explosion', {
start: 0,
end: 11
})
});
Note that start
is optional and you don't need to include it if the animation starts from frame 0.
To specify an animation in reverse, swap the start
and end
values.
If the frames are not sequential, you may pass an array of frame numbers instead, for example:
this.anims.generateFrameNumbers('explosion', { frames: [ 0, 1, 2, 1, 2, 3, 4, 0, 1, 2 ] })
Please see the animation examples and GenerateFrameNumbers
config docs for further details.

Removes a mix between two animations.
Mixing allows you to specify a unique delay between a pairing of animations.
Calling this method lets you remove those pairings. You can either remove
it between animA
and animB
, or if you do not provide the animB
parameter,
it will remove all animA
mixes.
If you wish to update an existing mix instead, call the addMix
method with the
new delay.

This Animation Manager.
Removes all listeners.
Takes an array of Game Objects that have an Animation Component and then
starts the given animation playing on them. The start time of each Game Object
is offset, incrementally, by the stagger
amount.
For example, if you pass an array with 4 children and a stagger time of 1000, the delays will be:
child 1: 1000ms delay child 2: 2000ms delay child 3: 3000ms delay child 4: 4000ms delay
If you set the staggerFirst
parameter to false
they would be:
child 1: 0ms delay child 2: 1000ms delay child 3: 2000ms delay child 4: 3000ms delay
You can also set stagger
to be a negative value. If it was -1000, the above would be:
child 1: 3000ms delay child 2: 2000ms delay child 3: 1000ms delay child 4: 0ms delay
