Spine is an animation tool that focuses specifically on 2D animation for games. Spine aims to have an efficient, streamlined workflow, both for creating animations using the editor and for making use of those animations in games using the Spine Runtimes.


Animation in Spine is done by attaching images to bones, then animating the bones. This is called skeletal or cutout animation and has numerous benefits over traditional, frame-by-frame animation:

  • Smaller size Traditional animation requires an image for each frame of animation. Spine animations store only the bone data, which is very small, allowing you to pack your game full of unique animations.
  • Art requirements Spine animations require much fewer art assets, freeing up time and money better spent on the game.
  • Smoothness Spine animations use interpolation so animation is always as smooth as the frame rate. Animations can be played in slow motion with no loss in quality.
  • Attachments Images attached to bones can be swapped to outfit a character with different items and effects. Animations can be reused for characters that look different, saving countless hours.
  • Mixing Animations can be blended together. For example, a character could play a shoot animation while also playing a walk, run or swim animation. Changing from one animation to another can be smoothly crossfaded.
  • Procedural animation Bones can be manipulated through code, allowing for effects like shooting toward the mouse position, looking toward nearby enemies, or leaning forward when running up hill.


Spine is packed with features to keep you productive while building great looking animations. Beyond the many editor features described below, the live demos for the Spine Runtimes show how animations can be layered and blended to achieve all kinds of dynamic behavior.Dopesheet

The dopesheet is at the heart of animating. It provides a detailed view of all the timelines that make up an animation and allows fine adjustments to be made to the animation’s timing.


The graph defines bezier curves for interpolation between keys, allowing for much more life-like movement.


Edit animations while seeing exactly how they will behave at runtime. This is crucial for transitions and crossfading between animations, as well as for applying multiple animations concurrently. For example, run and shoot, swim and shoot, etc.

Inverse Kinematics

Constraints can be defined to animate using inverse kinematics (IK) and the Pose tool uses multi-bone IK to quickly pose a skeleton.


Define paths using composite Bézier splines, then constrain bones to follow them. Paths make complex movement easy and enable advanced rigging by controlling a large number of bones in an intuitive way.


Skins allow switching between sets of attachments. They provide organization for attachments and enable animations that change attachments to be reused for different characters.

Bounding Boxes

A bounding box is a polygon that is attached to a bone. Like images, the polygon is manipulated as the bone moves. This can be used for hit detection and physics integration.


Make sure you have DirectX installed, otherwise the game will crash or can cause other issues. You can download DirectX from here

Spine runs on Windows Vista, 7, 8, on Mac OS X 10.7.3+, and on 32- and 64-bit Linux. Spine requires a graphics processor that supports OpenGL 2.0 or higher with the FBO extension. Nearly all modern computers should be able to run Spine. If you aren’t sure, download the trial to see how well it works.
