Software features

Minimum size: TraditionalanimationEach frame of image needs to be provided. Spine animation only saves the animation data of bones, which takes up very little space and can provide unique animation for your game.

​ ​ Art requirements: Spine animation requires fewer art resources, which can save you more manpower and material resources to better invest in game development.

Smoothness: Spine animation uses a difference algorithm to calculate intermediate frames, which allows your animation to always maintain a smooth effect.

Equipment accessories: Pictures are bound to bones to achieve animation. If you need, you can easily change the character's equipment to meet different needs. Even change the appearance of the character to achieve the effect of animation reuse.

​ ​ Mixing: Animations can be mixed between each other. For example, a character can shoot, walk, run, jump or swim at the same time.

Procedural animation: You can control the skeleton through code. For example, you can follow the mouse to shoot, watch the enemy, or lean forward when going uphill.

Function introduction

In the animation production process, the dope sheet is the most important place. All the important details are included here to create animations and fine-tune the timeline.

Grid

​​Allows you to customize polygons within rectangular boundaries. This will improve the space usage of the final texture atlas because pixels outside the polygon will be ignored. This optimization is especially important for mobile devices. Another feature of the mesh is to support free deformation and skinning.

Curve Editor

In the curve editor, you can control the difference between two frames by adjusting the Bezier curve to achieve lifelike animation effects.

Free deformation

Free deformation, also known as FFD, is the abbreviation of Free-Form Deformation, which allows you to deform pictures by moving grid points. FFD can realize the functions of the grid: stretching, extrusion, bending, rebound, and other functions that cannot be achieved by rectangular pictures.

skin

​ ​ Skins can switch picture materials for finished animations. Reuse animations by changing the image attached to the skeleton.

Bounding box

​​Bounding boxes can be attached to bones and move with them. It is mainly used for collision detection and physics integration.

Texture packaging

Spine can package images into texture atlases, which can improve your rendering efficiency in games. Spine's texture map packaging tool has many functions such as stripping blank areas, rotation, automatic scaling, etc... (the main purpose is to make full use of space)

Software Highlights

Linear is the default curve type, linearly interpolating between keyframe values. This means that when the time axis position moves from the first keyframe to the second keyframe, the value changes at a constant rate

2. Bessel

The Bezier curve type uses Bezier curves to interpolate between keyframe values. A Bezier curve has two handles that can be dragged to customize the rate at which the value changes between keyframes.

3. Ladder

Step curves do not use interpolation at all. The value remains unchanged until the next frame.
