Creating a character with images that can bend becomes as easy as just positioning the bones. When the bones move, the vertices move with them and the mesh deforms automatically. Weights (often referred to as “skinning”) allow you to attach individual mesh vertices to different bones.FFD allows meshes to stretch, shrink, bend, and bounce in ways that are not possible with rectangular images. Freeform Deformation (FFD) allows you to move individual mesh vertices to deform the image.This improves fill speed because pixels outside of the polygon won’t be drawn, which is especially important for mobile games. Instead of drawing rectangles, grids allow you to specify a polygon within your image.

This can be used for hit detection and physics integration. Like images, the polygon changes as the bone moves. Use a bounding box, which is a polygon attached to a bone.They provide organization for attachments and allow attachment-changing animations to be reused for different characters. Skins allow you to switch between sets of attachments.Define paths with Bezier splines, then set the bones to follow those paths and advanced rigging functions, controlling a large number of bones appropriately.IK Posing with Inverse Kinematics and use the multi-bone kinematics pose tool to position the skeleton.Simultaneous application of several animations, for example, running and shooting, swimming and shooting, etc.Easily edit animations and edit the behavior of animations at runtime.Use graph to define bezier curves to interpolate between keys for more realistic movements.Create various dropdown table animations and makeover animations with fine tuning.Users can achieve any dynamic behavior and provide detailed insight into runtime environments.Use live demos for Spine runtimes to learn layers and blending.Provides many powerful tools and interactive animations.Complete 2D animation software for games.It comes with support for runtimes that show how animations can be layered and blended to achieve all sorts of dynamic behaviors. The procedural animation bones are code-driven and support adding effects, including firing at mouse position, finding nearby enemies, and leaning forward while running uphill. Mix animations to be blended together, and the character can play shooting animation, as well as play walking, running or swimming and various other actions.
