    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.

    Properties

    The Animations registered in the Animation Manager.

    This map should be modified with the #add and #create methods of the Animation Manager.

    game: Game

    A reference to the Phaser.Game instance.

    globalTimeScale: number

    The global time scale of the Animation Manager.

    This scales the time delta between two frames, thus influencing the speed of time for the Animation Manager.

    A list of animation mix times.

    See the #setMix method for more details.

    name: string

    The name of this Animation Manager.

    paused: boolean

    Whether the Animation Manager is paused along with all of its Animations.

    textureManager: TextureManager

    A reference to the Texture Manager.

    Methods

    • Adds an existing Animation to the Animation Manager.

      Parameters

      • key: string

        The key under which the Animation should be added. The Animation will be updated with it. Must be unique.

      • animation: Animations.Animation

        The Animation which should be added to the Animation Manager.

      Returns this

    • Add a listener for a given event.

      Parameters

      • event: string | symbol

        The event name.

      • fn: Function

        The listener function.

      • Optionalcontext: any

        The context to invoke the listener with. Default this.

      Returns this

    • 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.

      Parameters

      • animA: string | Animations.Animation

        The string-based key, or instance of, Animation A.

      • animB: string | Animations.Animation

        The string-based key, or instance of, Animation B.

      • delay: number

        The delay, in milliseconds, to wait when transitioning from Animation A to B.

      Returns this

    • 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.

      Parameters

      Returns false | Animations.Animation

    • 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:

      1. Go to "File - Export Sprite Sheet"

      2. On the Layout tab: 2a. Set the "Sheet type" to "Packed" 2b. Set the "Constraints" to "None" 2c. Check the "Merge Duplicates" checkbox

      3. 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

      4. 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)

      5. 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.

      6. 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.

      Parameters

      • key: string

        The key of the loaded Aseprite atlas. It must have been loaded prior to calling this method.

      • Optionaltags: string[]

        An array of Tag names. If provided, only animations found in this array will be created.

      • Optionaltarget: GameObject | AnimationManager

        Create the animations on this target Sprite. If not given, they will be created globally in this Animation Manager.

      Returns Animations.Animation[]

    • Destroy this Animation Manager and clean up animation definitions and references to other objects. This method should not be called directly. It will be called automatically as a response to a destroy event from the Phaser.Game instance.

      Returns void

    • Calls each of the listeners registered for a given event.

      Parameters

      • event: string | symbol

        The event name.

      • ...args: any[]

        Additional arguments that will be passed to the event handler.

      Returns boolean

    • Checks to see if the given key is already in use within the Animation Manager or not.

      Animations are global. Keys created in one scene can be used from any other Scene in your game. They are not Scene specific.

      Parameters

      • key: string

        The key of the Animation to check.

      Returns boolean

    • 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.

      Parameters

      • key: string

        The key for the texture containing the animation frames.

      • Optionalconfig: GenerateFrameNames

        The configuration object for the animation frame names.

      Returns Types.Animations.AnimationFrame[]

    • 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.

      Parameters

      • key: string

        The key for the texture containing the animation frames.

      • Optionalconfig: GenerateFrameNumbers

        The configuration object for the animation frames.

    • Returns an array of all Animation keys that are using the given Texture. Only Animations that have at least one AnimationFrame entry using this texture will be included in the result.

      Parameters

      • key: string | Textures.Texture | Frame

        The unique string-based key of the Texture, or a Texture, or Frame instance.

      Returns string[]

    • Returns the mix delay between two animations.

      If no mix has been set-up, this method will return zero.

      If you wish to create, or update, a new mix, call the addMix method. If you wish to remove a mix, call the removeMix method.

      Returns this

    • 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.

      Parameters

      • animA: string | Animations.Animation

        The string-based key, or instance of, Animation A.

      • OptionalanimB: string | Animations.Animation

      Returns this

    • 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
