# spine-as3

The spine-as3 runtime provides functionality to load and manipulate [Spine](http://esotericsoftware.com) skeletal animation data using Adobe's ActionScript 3.0 (AS3). The [`spine.flash` package](spine-as3/src/spine/flash) 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](../spine-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](https://esotericsoftware.com/spine-purchase). Please see the [Spine Runtimes Software License](http://esotericsoftware.com/git/spine-runtimes/blob/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](https://esotericsoftware.com/files/license.txt) 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](http://fdt.powerflasher.com/) as your development environment.

1. Download [FDT free](http://fdt.powerflasher.com/buy-download/) for your operating system.
3. Download and install [Adobe Flash Player 23 with debugging support](https://www.adobe.com/support/flashplayer/debug_downloads.html#fp15)
2. Download the latest [Flex SDK](http://www.adobe.com/devnet/flex/flex-sdk-download.html). We assume it will be installed to some folder on your disk called `flex_sdk`.
3. Download the latest [Adobe AIR SDK](http://www.adobe.com/devnet/air/air-sdk-download.html)
4. Extract the AIR SDK contents, and copy them to your `flex_sdk` folder. This will replace the Adobe AIR version shipped with Flex.
5. Open FDT, go to `Preferences -> FDT -> Installed SDKs`
6. Click `Add` and browse to `flex_sdk`
7. Go to `File -> Import -> General -> Existing Projects into Workspace`
6. Browse to `spine-as3/`. You should see both the `spine-as3` and `spine-as3-example` project in the import dialog. Click `Finish`
8. 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`.
