Spine is a special tool for creating animated 2D animations in the game. Spine strives to have an efficient, streamlined workflow for both creating animations by the editor and using those animations in the Spine Runtime. Animation in Spine is done by attaching an image to a bone and then creating an animation for the bones. This is called bone frame animation or cut animation and has many advantages over traditional animation.
Spine is integrated with features that will help you work efficiently. In addition to the many editor features described below, live shows for Spine Runtimes show how animation can be layered and combined to achieve all sorts of actions.
Add. information :
Smaller size: Traditional animation requires an image for each frame of animation. Spine animation only stores bone data, which is very small, allowing you to fill the game with unique animations.
Art Requirements: Spine requires far fewer art assets to animate, saving time and money that could be better spent on the game.
Smooth: Spine animation uses interpolation so the animation is always as smooth as the frame rate. Animation can be played in slow motion without losing quality.
Attachments: The images attached to bones can be swapped around to provide different items and effects to your character. Animations can be reused for characters that look different, saving countless hours.
Blending: Animations can be mixed. For example, a character can play a shooting animation while simultaneously playing a walking, running, or swimming animation. The transition from one animation to another can smoothly transition into a smooth transition mode.
Procedural Animation: Bone can be manipulated through code, allowing for effects such as shooting in the direction of the mouse position, looking at nearby enemies, or leaning forward when running uphill.
