  • Breaking changes

  • Removed Bone.worldToLocalRotationX and Bone.worldToLocalRotationY. Replaced by Bone.worldToLocalRotation (rotation given relative to x-axis, counter-clockwise, in degrees).

  • Made Bone fields _a, _b, _c, _d, _worldX and _worldY public, removed underscore prefix.

  • Removed VertexAttachment.computeWorldVertices overload, changed VertexAttachment.computeWorldVertices2 to VertexAttachment.computeWorldVertices, added stride parameter.

  • Removed RegionAttachment.vertices field. The vertices array is provided to RegionAttachment.computeWorldVertices by the API user now.

  • Removed RegionAttachment.updateWorldVertices, added RegionAttachment.computeWorldVertices. The new method now computes the x/y positions of the 4 vertices of the corner and places them in the provided worldVertices array, starting at offset, then moving by stride array elements when advancing to the next vertex. This allows to directly compose the vertex buffer and avoids a copy. The computation of the full vertices, including vertex colors and texture coordinates, is now done by the backend's respective renderer.

  • Replaced r, g, b, a fields with instances of new Color class in RegionAttachment, MeshAttachment, Skeleton, SkeletonData, Slot and SlotData.

  • The completion event will fire for looped 0 duration animations every frame.

  • Additions

  • Added Skeleton.getBounds from reference implementation.

  • Added support for local and relative transform constraint calculation, including additional fields in TransformConstraintData

  • Added Bone.localToWorldRotation(rotation given relative to x-axis, counter-clockwise, in degrees).

  • Added two color tinting support, including TwoColorTimeline and additional fields on Slot and SlotData.

  • Added PointAttachment, additional method newPointAttachment in AttachmentLoader interface.

  • Added ClippingAttachment, additional method newClippingAttachment in AttachmentLoader interface.

  • AnimationState#apply returns boolean indicating if any timeline was applied or not.

  • Animation#apply and Timeline#apply`` now take enums MixPoseandMixDirection` instead of booleans

  • Added VertexEffect and implementations JitterEffect and SwirlEffect. Allows you to modify vertices before they are submitted for drawing. See Starling changes.

Starling

  • Fixed renderer to work with 3.6 changes.
  • Added support for two color tinting.
  • Added support for clipping.
  • Added support for rotated regions in texture atlas loaded via StarlingAtlasAttachmentLoader.
  • Added support for vertex effects. See RaptorExample.as
  • Added 'getTexture()' method to 'StarlingTextureAtlasAttachmentLoader'
  • Breaking change: if a skeleton requires two color tinting, you have to enable it via SkeletonSprite.twoColorTint = true. In this case the skeleton will use the TwoColorMeshStyle, which internally uses a different vertex layout and shader. This means that skeletons with two color tinting enabled will break batching and hence increase the number of draw calls in your app.

C

  • Breaking changes
  • spVertexAttachment_computeWorldVertices and spRegionAttachment_computeWorldVerticeS now take new parameters to make it possible to directly output the calculated vertex positions to a vertex buffer. Removes the need for additional copies in the backends' respective renderers.
  • Removed spBoundingBoxAttachment_computeWorldVertices, superseded by spVertexAttachment_computeWorldVertices.
  • Removed spPathAttachment_computeWorldVertices and spPathAttachment_computeWorldVertices1, superseded by spVertexAttachment_computeWorldVertices.
  • Removed sp_MeshAttachment_computeWorldVertices, superseded by spVertexAttachment_computeWorldVertices.
  • Removed spBone_worldToLocalRotationX and spBone_worldToLocalRotationY. Replaced by spBone_worldToLocalRotation (rotation given relative to x-axis, counter-clockwise, in degrees).
  • Replaced r, g, b, a fields with instances of new spColor struct in spRegionAttachment, spMeshAttachment, spSkeleton, spSkeletonData, spSlot and spSlotData.
  • Removed spVertexIndexfrom public API.
  • Listeners on spAnimationState or spTrackEntry will now be also called in case a track entry is disposed as part of dispoing the spAnimationState.
  • The completion event will fire for looped 0 duration animations every frame.
  • Additions
  • Added support for local and relative transform constraint calculation, including additional fields in spTransformConstraintData.
  • Added spPointAttachment, additional method spAtlasAttachmentLoadeR_newPointAttachment.
  • Added support for local and relative transform constraint calculation, including additional fields in TransformConstraintData
  • Added spBone_localToWorldRotation(rotation given relative to x-axis, counter-clockwise, in degrees).
  • Added two color tinting support, including spTwoColorTimeline and additional fields on spSlot and spSlotData.
  • Added userData field to spTrackEntry, so users can expose data in spAnimationState callbacks.
  • Modified kvec.h used by SkeletonBinary.c to use Spine's MALLOC/FREE macros. That way there's only one place to inject custom allocators (extension.h) commit
  • Added macros to define typed dynamic arrays, see Array.h/.c
  • Added spClippingAttachment and respective enum.
  • Added spSkeletonClipper and spTriangulator, used to implement software clipping of attachments.
  • AnimationState#apply returns boolean indicating if any timeline was applied or not.
  • Animation#apply and Timeline#apply`` now take enums MixPoseandMixDirection` instead of booleans
  • Added spVertexEffect and corresponding implementations spJitterVertexEffect and spSwirlVertexEffect. Create/dispose through the corresponding spXXXVertexEffect_create()/dispose() functions. Set on framework/engine specific renderer. See changes for spine-c based frameworks/engines below.
  • Functions in extension.h are not prefixed with _sp instead of just _ to avoid interference with other libraries.
  • Introduced SP_API macro. Every spine-c function is prefixed with this macro. By default, it is an empty string. Can be used to markup spine-c functions with e.g. ``__declspec` when compiling to a dll or linking to that dll.

Cocos2d-X

  • Fixed renderer to work with 3.6 changes
  • Optimized rendering by removing all per-frame allocation in SkeletonRenderer, resulting in 15% performance increase for large numbers of skeletons being rendered per frame.
  • Added support for two color tinting. Tinting is enabled/disabled per SkeletonRenderer/SkeletonAnimation instance. Use SkeletonRenderer::setTwoColorTint(). Note that two color tinting requires the use of a non-standard shader and vertex format. This means that skeletons rendered with two color tinting will break batching. However, skeletons with two color tinting enabled and rendered after each other will be batched.
  • Updated example to use Cocos2d-x 3.14.1.
  • Added mesh debug rendering. Enable/Disable via SkeletonRenderer::setDebugMeshesEnabled().
  • Added support for clipping.
  • SkeletonRenderer now combines the displayed color of the Node (cascaded from all parents) with the skeleton color for tinting.
  • Added support for vertex effects. See RaptorExample.cpp.
  • Added ETC1 alpha support, thanks @halx99! Does not work when two color tint is enabled.
  • Added spAtlasPage_setCustomTextureLoader() which let's you do texture loading manually. Thanks @jareguo.
  • Added SkeletonRenderer:setSlotsRange() and SkeletonRenderer::createWithSkeleton(). This allows you to split rendering of a skeleton up into multiple parts, and render other nodes in between. See SkeletonRendererSeparatorExample.cpp for an example.

Cocos2d-Objc

  • Fixed renderer to work with 3.6 changes
  • Added support for two color tinting. Tinting is enabled/disabled per SkeletonRenderer/SkeletonAnimation.twoColorTint = true. Note that two color tinted skeletons do not batch with other nodes.
  • Added support for clipping.

SFML

  • Fixed renderer to work with 3.6 changes. Sadly, two color tinting does not work, as the vertex format in SFML is fixed.
  • Added support for clipping.
  • Added support for vertex effects. See raptor example.
  • Added premultiplied alpha support to SkeletonDrawable.

Unreal Engine 4

  • Fixed renderer to work with 3.6 changes
  • Added new UPROPERTY to SpineSkeletonRendererComponent called Color. This allows to set the tint color of the skeleton in the editor, C++ and Blueprints. Under the hood, the spSkeleton->color will be set on every tick of the renderer component.
  • Added support for clipping.
  • Switched from built-in ProceduralMeshComponent to RuntimeMeshComponent by Koderz (https://github.com/Koderz/UE4RuntimeMeshComponent, MIT). Needed for more flexibility regarding vertex format, should not have an impact on existing code/assets. You need to copy the RuntimeMeshComponentPlugin from our repository in spine-ue4\Plugins\ to your project as well!
  • Added support for two color tinting. All base materials, e.g. SpineUnlitNormalMaterial, now do proper two color tinting. No material parameters have changed.
  • Updated to Unreal Engine 4.16.1. Note that 4.16 has a regression which will make it impossible to compile plain .c files!
  • spine-c is now exposed from the plugin shared library on Windows via __declspec.
  • Updated to Unreal Engine 4.18

C#

  • Breaking changes

    • MeshAttachment.parentMesh is now a private field to enforce using the .ParentMesh setter property in external code. The MeshAttachment.ParentMesh property is an appropriate replacement wherever .parentMesh was used.
    • Skeleton.GetBounds takes a scratch array as input so it doesn't have to allocate a new array on each invocation itself. Reduces GC activity.
    • Removed Bone.WorldToLocalRotationX and Bone.WorldToLocalRotationY. Replaced by Bone.WorldToLocalRotation (rotation given relative to x-axis, counter-clockwise, in degrees).
    • Added stride parameter to VertexAttachment.ComputeWorldVertices.
    • Removed RegionAttachment.Vertices field. The vertices array is provided to RegionAttachment.ComputeWorldVertices by the API user now.
    • Removed RegionAttachment.UpdateWorldVertices, added RegionAttachment.ComputeWorldVertices. The new method now computes the x/y positions of the 4 vertices of the corner and places them in the provided worldVertices array, starting at offset, then moving by stride array elements when advancing to the next vertex. This allows to directly compose the vertex buffer and avoids a copy. The computation of the full vertices, including vertex colors and texture coordinates, is now done by the backend's respective renderer.
    • The completion event will fire for looped 0 duration animations every frame.

  • Additions

  • Added support for local and relative transform constraint calculation, including additional fields in TransformConstraintData

  • Added Bone.localToWorldRotation(rotation given relative to x-axis, counter-clockwise, in degrees).

  • Added two color tinting support, including TwoColorTimeline and additional fields on Slot and SlotData.

  • Added PointAttachment, additional method NewPointAttachment in AttachmentLoader interface.

  • Added ClippingAttachment, additional method NewClippingAttachment in AttachmentLoader interface.

  • Added SkeletonClipper and Triangulator, used to implement software clipping of attachments.

  • AnimationState.Apply returns a bool indicating if any timeline was applied or not.

  • Animation.Apply and Timeline.Apply`` now take enums MixPoseandMixDirection` instead of bools.

Unity

  • Refactored renderer to work with new 3.6 features.
    • Two color tinting is currently supported via extra UV2 and UV3 mesh vertex streams. To use Two color tinting, you need to:
      • switch on "Tint Black" under "Advanced...",
      • use the new Spine/Skeleton Tint Black shader, or your own shader that treats the UV2 and UV3 streams similarly.
      • Additionally, for SkeletonGraphic, you can use Spine/SkeletonGraphic Tint Black (or the bundled SkeletonGraphicTintBlack material) or your own shader that uses UV2 and UV3 streams similarly. Additional Shader Channels TexCoord1 and TexCoord2 will need to be enabled from the Canvas component's inspector. These correspond to UV2 and UV3.
    • Clipping is now supported. Caution: The SkeletonAnimation switches to slightly slower mesh generation code when clipping so limit your use of ClippingAttachments when using on large numbers of skeletons.
  • SkeletonRenderer.initialFlip Spine components such as SkeletonRenderer, SkeletonAnimation, SkeletonAnimator now has initialFlipX and initialFlipY fields which are also visible in the inspector under "Advanced...". It will allow you to set and preview a starting flip value for your skeleton component. This is applied immediately when the internal skeleton object is instantiated.
  • [SpineAttribute] Improvements
    • Icons have been added to SpineAttributeDrawers. This should make your default inspectors easier to understand at a glance.
    • Added Constraint Attributes You can now use [SpineIkConstraint] [SpineTransformConstraint] [SpinePathConstraint]
    • SpineAttribute dataField parameter can also now detect sibling fields within arrays and serializable structs/classes.
    • [SpineAttribute(includeNone:false)] SpineAttributes now have an includeNone optional parameter to specify if you want to include or exclude a none ("") value option in the dropdown menu. Default is includeNone:true.
    • [SpineAttachment(skinField:"mySkin")] The SpineAttachment attribute now has a skinField optional parameter to limit the dropdown items to attachments in a specific skin instead of the just default skin or all the skins in SkeletonData.
  • SkeletonDebugWindow. Debugging tools have been moved from the SkeletonAnimation and SkeletonUtility component inspectors into its own utility window. You can access "Skeleton Debug" under the Advanced... foldout in the SkeletonAnimation inspector, or in SkeletonAnimation's right-click/context menu.
    • Skeleton Baking Window The old Skeleton Baking feature is also now accessible through the SkeletonDataAsset's right-click/context menu.
  • AttachmentTools source material. AttachmentTools methods can now accept a sourceMaterial argument to copy material properties from.
  • AttachmentTools Skin Extensions. Using AttachmentTools, you can now add entries by slot name by also providing a skeleton argument. Also Append(Skin), RemoveAttachment and Clear have been added.
  • BoneFollower and SkeletonUtilityBone Add RigidBody Button. The BoneFollower and SkeletonUtilityBone component inspectors will now offer to add a Rigidbody or Rigidbody2D if it detects a collider of the appropriate type. Having a rigidbody on a moving transform with a collider fits better with the Unity physics systems and prevents excess calculations. It will not detect colliders on child objects so you have to add Rigidbody components manually accordingly.
  • SkeletonRenderer.OnPostProcessVertices is a new callback that gives you a reference to the MeshGenerator after it has generated a mesh from the current skeleton pose. You can access meshGenerator.VertexBuffer or meshGenerator.ColorBuffer to modify these before they get pushed into the UnityEngine.Mesh for rendering. This can be useful for non-shader vertex effects.
  • Examples
    • Examples now use properties. The code in the example scripts have been switched over to using properties instead of fields to encourage their use for consistency. This is in anticipation of both users who want to move the Spine folders to the Unity Plugins folder (compiled as a different assembly), and of Unity 2017's ability to manually define different assemblies for shorter compilation times.
    • Mix And Match. The mix-and-match example scene, code and data have been updated to reflect the current recommended setup for animation-compatible custom equip systems The underlying API has changed since 3.5 and the new API calls in MixAndMatch.cs is recommended. Documentation is in progress.
    • Sample Components. AtasRegionAttacher and SpriteAttacher are now part of Sample Components, to reflect that they are meant to be used as sample code rather than production. A few other sample components have also been added. New imports of the unitypackage Examples folder will see a "Legacy" folder comprised of old sample components that no longer contain the most up-to-date and recommended workflows, but are kept in case old setups used them for production.
  • Spine folder. In the unitypackage, the "spine-csharp" and "spine-unity" folders are now inside a "Spine" folder. This change will only affect fresh imports. Importing the unitypackage to update Spine-Unity in your existing project will update the appropriate files however you chose to arrange them, as long as the meta files are intact.
  • Breaking changes
    • The Sprite shaders module was updated to the latest version from the source. Some changes were made to the underlying keyword structure. You may need to review the settings of your lit materials. Particularly, your Fixed Normals settings.
    • The Spine/Skeleton Lit shader was switched over to non-fixed-function code. It now no longer requires mesh normals and has fixed normals at the shader level.
    • The old MeshGenerator classes, interfaces and code in Spine.Unity.MeshGeneration are now deprecated. All mesh-generating components now share the class Spine.Unity.MeshGenerator defined in SpineMesh.cs. MeshGenerator is a serializable class.
      • The SkeletonRenderer.renderMeshes optimization is currently non-functional.
      • Old triangle-winding code has been removed from SkeletonRenderer. Please use shaders that have backface culling off.
      • Render settings in SkeletonGraphic can now be accessed under SkeletonGraphic.MeshGenerator.settings. This is visible in the SkeletonGraphic inspector as Advanced...
      • We will continue to bundle the unitypackage with the empty .cs files of deprecated classes until Spine 3.7 to ensure the upgrade process does not break.
    • The [SpineAttachment(slotField:)] optional parameter found property value now acts as a Find(slotName) argument rather than Contains(slotName).
    • SkeletonAnimator now uses a SkeletonAnimator.MecanimTranslator class to translate an Animator's Mecanim State Machine into skeleton poses. This makes code reuse possible for a Mecanim version of SkeletonGraphic.
    • SkeletonAnimator autoreset and the mixModes array are now a part of SkeletonAnimator's MecanimTranslator .Translator. autoReset is set to true by default. Old prefabs and scene objects with Skeleton Animator may no longer have correct values set.
    • Warnings and conditionals checking for specific Unity 5.2-and-below incompatibility have been removed.

XNA/MonoGame

  • Added support for clipping
  • Removed RegionBatcher and SkeletonRegionRenderer, renamed SkeletonMeshRenderer to SkeletonRenderer
  • Added support for two color tint. For it to work, you need to add the SpineEffect.fx file to your content project, then load it via var effect = Content.Load<Effect>("SpineEffect");, and set it on the SkeletonRenderer. See the example project for code.
  • Added support for any Effect to be used by SkeletonRenderer
  • Added support for IVertexEffect to modify vertices of skeletons on the CPU. IVertexEffect instances can be set on the SkeletonRenderer. See example project.
  • Added SkeletonDebugRenderer
  • Made MeshBatcher of SkeletonRenderer accessible via a getter. Allows user to batch their own geometry together with skeleton meshes for maximum batching instead of using XNA SpriteBatcher.

Java

  • Breaking changes

  • Skeleton.getBounds takes a scratch array as input so it doesn't have to allocate a new array on each invocation itself. Reduces GC activity.

  • Removed Bone.worldToLocalRotationX and Bone.worldToLocalRotationY. Replaced by Bone.worldToLocalRotation (rotation given relative to x-axis, counter-clockwise, in degrees).

  • Added stride parameter to VertexAttachment.computeWorldVertices.

  • Removed RegionAttachment.vertices field. The vertices array is provided to RegionAttachment.computeWorldVertices by the API user now.

  • Removed RegionAttachment.updateWorldVertices, added RegionAttachment.computeWorldVertices. The new method now computes the x/y positions of the 4 vertices of the corner and places them in the provided worldVertices array, starting at offset, then moving by stride array elements when advancing to the next vertex. This allows to directly compose the vertex buffer and avoids a copy. The computation of the full vertices, including vertex colors and texture coordinates, is now done by the backend's respective renderer.

  • Skeleton attachments: Moved update of attached skeleton out of libGDX SkeletonRenderer, added overloaded method Skeleton#updateWorldTransform(Bone), used for SkeletonAttachment. You now MUST call this new method with the bone of the parent skeleton to which the child skeleton is attached. See SkeletonAttachmentTest` for and example.

  • The completion event will fire for looped 0 duration animations every frame.

  • Additions

  • Added support for local and relative transform constraint calculation, including additional fields in TransformConstraintData

libGDX

  • Fixed renderer to work with 3.6 changes
  • Added support for two color tinting. Use the new TwoColorPolygonBatch together with SkeletonRenderer
  • Added support for clipping. See SkeletonClipper. Used automatically by SkeletonRenderer. Does not work when using a SpriteBatch with SkeletonRenderer. Use PolygonSpriteBatch or TwoColorPolygonBatch instead.
  • Added VertexEffect interface, instances of which can be set on SkeletonRenderer. Allows to modify vertices before submitting them to GPU. See SwirlEffect, JitterEffect and VertexEffectTest.

Lua

  • Breaking changes
  • Removed Bone:worldToLocalRotationX and Bone:worldToLocalRotationY. Replaced by Bone:worldToLocalRotation (rotation given relative to x-axis, counter-clockwise, in degrees).
  • VertexAttachment:computeWorldVertices now takes offsets and stride to allow compositing vertices directly in a vertex buffer to be send to the GPU. The compositing is now performed in the backends' respective renderers. This also affects the subclasses MeshAttachment, BoundingBoxAttachment and PathAttachment.
  • Removed RegionAttachment:updateWorldVertices, added RegionAttachment:computeWorldVertices, which takes offsets and stride to allow compositing vertices directly in a vertex buffer to be send to the GPU. The compositing is now performed in the backends' respective renderers.
  • Removed MeshAttachment.worldVertices field. Computation is now performed in each backends' respective renderer. The uv coordinates are now stored in MeshAttachment.uvs.
  • Removed RegionAttachment.vertices field. Computation is now performed in each backends respective renderer. The uv coordinates for each vertex are now stored in the RegionAttachment.uvs field.
  • The completion event will fire for looped 0 duration animations every frame.

Love2D

  • Fixed renderer to work with 3.6 changes
  • Added support for two color tinting. Enable it via SkeletonRenderer.new(true).
  • Added clipping support.
  • Added support for vertex effects. Set an implementation like "JitterEffect" on Skeleton.vertexEffect. See main.lua for an example.

Corona

  • Fixed renderer to work with 3.6 changes. Sadly, two color tinting is not supported, as Corona doesn't let us change the vertex format needed and its doesn't allow to modify shaders in the way needed for two color tinting
  • Added clipping support.
  • Added support for vertex effects. Set an implementation like "JitterEffect" on SkeletonRenderer.vertexEffect. See main.lua for an example

Typescript/Javascript

  • Breaking changes

  • Skeleton.getBounds takes a scratch array as input so it doesn't have to allocate a new array on each invocation itself. Reduces GC activity.

  • Removed Bone.worldToLocalRotationX and Bone.worldToLocalRotationY. Replaced by Bone.worldToLocalRotation (rotation given relative to x-axis, counter-clockwise, in degrees).

  • Removed VertexAttachment.computeWorldVertices overload, changed VertexAttachment.computeWorldVerticesWith to VertexAttachment.computeWorldVertices, added stride parameter.

  • Removed RegionAttachment.vertices field. The vertices array is provided to RegionAttachment.computeWorldVertices by the API user now.

  • Removed RegionAttachment.updateWorldVertices, added RegionAttachment.computeWorldVertices. The new method now computes the x/y positions of the 4 vertices of the corner and places them in the provided worldVertices array, starting at offset, then moving by stride array elements when advancing to the next vertex. This allows to directly compose the vertex buffer and avoids a copy. The computation of the full vertices, including vertex colors and texture coordinates, is now done by the backend's respective renderer.

  • The completion event will fire for looped 0 duration animations every frame.

  • Additions

  • Added support for local and relative transform constraint calculation, including additional fields in TransformConstraintData

  • Added Bone.localToWorldRotation(rotation given relative to x-axis, counter-clockwise, in degrees).

  • Added two color tinting support, including TwoColorTimeline and additional fields on Slot and SlotData.

  • Added PointAttachment, additional method newPointAttachment in AttachmentLoader interface.

  • Added ClippingAttachment, additional method newClippingAttachment in AttachmentLoader interface.

  • Added SkeletonClipper and Triangulator, used to implement software clipping of attachments.

  • AnimationState#apply returns boolean indicating if any timeline was applied or not.

  • Animation#apply and Timeline#apply`` now take enums MixPoseandMixDirection` instead of booleans

  • Added AssetManager.loadTextureAtlas. Instead of loading the .atlas and corresponding image files manually, you can simply specify the location of the .atlas file and AssetManager will load the atlas and all its images automatically. AssetManager.get("atlasname.atlas") will then return an instance of spine.TextureAtlas.

WebGL backend

  • Fixed WebGL context loss
    • Added Restorable interface, implemented by any WebGL resource that needs restoration after a context loss. All WebGL resource classes (Shader, Mesh, GLTexture) implement this interface.
    • Added ManagedWebGLRenderingContext. Handles setup of a WebGLRenderingContext given a canvas element and restoration of WebGL resources (Shader, Mesh, GLTexture) on WebGL context loss. WebGL resources register themselves with the ManagedWebGLRenderingContext. If the context is informed of a context loss and restoration, the registered WebGL resources' restore() method is called. The restore() method implementation on each resource type will recreate the GPU side objects.
    • All classes that previously took a WebGLRenderingContext in the constructor now also allow a ManagedWebGLRenderingContext. This ensures existing applications do not break.
    • To use automatic context restauration:
    1. Create or fetch a canvas element from the DOM
    2. Instantiate a ManagedWebGLRenderingContext, passing the canvas to the constructor. This will setup a WebGLRenderingContext internally and manage context loss/restoration.
    3. Pass the ManagedWebGLRenderingContext to the constructors of classes that you previously passed a WebGLRenderingContext to (AssetManager, GLTexture, Mesh, Shader, PolygonBatcher, SceneRenderer, ShapeRenderer, SkeletonRenderer, SkeletonDebugRenderer).
  • Fixed renderer to work with 3.6 changes.
  • Added support for two color tinting.
  • Improved performance by using DYNAMIC_DRAW for vertex buffer objects and fixing bug that copied to much data to the GPU each frame in PolygonBatcher/Mesh.
  • Added two color tinting support, enabled by default. You can disable it via the constructors of SceneRenderer, SkeletonRendererand PolygonBatcher. Note that you will need to use a shader created via Shader.newTwoColoredTexturedShader shader with SkeletonRenderer and PolygonBatcher if two color tinting is enabled.
  • Added clipping support
  • Added VertexEffect interface, instances of which can be set on SkeletonRenderer. Allows to modify vertices before submitting them to GPU. See SwirlEffect, JitterEffect, and the example which allows to set effects.
  • Added slotRangeStart and slotRangeEnd parameters to SkeletonRenderer#draw and SceneRenderer#drawSkeleton. This allows you to render only a range of slots in the draw order. See spine-ts/webgl/tests/test-slot-range.html for an example.

Canvas backend

  • Fixed renderer to work for 3.6 changes. Sadly, we can't support two color tinting via the Canvas API.
  • Added support for shearing and non-uniform scaling inherited from parent bones.
  • Added support for alpha tinting.

Three.js backend

  • Fixed renderer to work with 3.6 changes. Two color tinting is not supported.
  • Added clipping support
  • Added VertexEffect interface, instances of which can be set on SkeletonMesh. Allows to modify vertices before submitting them to GPU. See SwirlEffect, JitterEffect.
  • Added support for multi-page atlases

Widget backend

  • Fixed WebGL context loss (see WebGL backend changes). Enabled automatically.
  • Fixed renderer to work for 3.6 changes. Supports two color tinting & clipping (see WebGL backend changes for details).
  • Added fields atlasContent, atlasPagesContent, and jsonContent to WidgetConfiguration allowing you to directly pass the contents of the .atlas, atlas page .png files, and the .json file without having to do a request. See README.md and the example for details.
  • SpineWidget.setAnimation() now takes an additional optional parameter for callbacks when animations are completed/interrupted/etc.
