spine-as3

The spine-as3 runtime provides functionality to load and manipulate Spine skeletal animation data using Adobe's ActionScript 3.0 (AS3). The spine.flash package can be used to render Spine animations using Flash. spine-as3 can be extended to enable Spine animations for other AS3 projects, such as Starling.

Licensing

This Spine Runtime may only be used for personal or internal use, typically to evaluate Spine before purchasing. If you would like to incorporate a Spine Runtime into your applications, distribute software containing a Spine Runtime, or modify a Spine Runtime, then you will need a valid Spine license. Please see the Spine Runtimes Software License for detailed information.

The Spine Runtimes are developed with the intent to be used with data exported from Spine. By purchasing Spine, Section 2 of the Spine Software License grants the right to create and distribute derivative works of the Spine Runtimes.

Spine version

spine-as3 works with data exported from Spine 3.7.xx.

spine-as3 supports all Spine features, including meshes. If using the spine.flash classes for rendering, meshes are not supported.

spine-as3 does not yet support loading the binary format.

Usage

  1. Create a new Flex or Adobe AIR project in your preferred IDE.
  2. Download the Spine Runtimes source using git (git clone https://github.com/esotericsoftware/spine-runtimes) or download it as a ZIP by clicking the download button above.
  3. Add the sources from spine-as3/spine-as3/src/ to your project

Example

The Spine AS3 example works on Windows, Linux and Mac OS X. This guide assumes you are using FDT Free as your development environment.

  1. Download FDT free for your operating system.
  2. Download and install Adobe Flash Player 23 with debugging support
  3. Download the latest Flex SDK. We assume it will be installed to some folder on your disk called flex_sdk.
  4. Download the latest Adobe AIR SDK
  5. Extract the AIR SDK contents, and copy them to your flex_sdk folder. This will replace the Adobe AIR version shipped with Flex.
  6. Open FDT, go to Preferences -> FDT -> Installed SDKs
  7. Click Add and browse to flex_sdk
  8. Go to File -> Import -> General -> Existing Projects into Workspace
  9. Browse to spine-as3/. You should see both the spine-as3 and spine-as3-example project in the import dialog. Click Finish
  10. Right click the Main.as file in spine-as3-example/src/spine in the FDT explorer and select Debug As -> FDT SWF Application

Note: FDT Free does not allow project dependencies. If you modify the sources of spine-as3, you will have to compile the project to an .swc and place it in spine-as3-example/libs.
