Abstract: A method and a system of automatically generating animations imports Json data exported from a Spine tool into a Unity3d tool, parses the Json data into an animation data format by the Unity3d tool, obtains key frame information from the animation data format and stores the key frame information as an animation file of the Unity3d tool, and runs the animation file to play an animation. The present invention does not need to remake the Spine key frame in the Unity3d tool, and the key frame can be automatically generated. The animation key frame effects of the Spine tool can be reproduced, such as displacement, zooming, rotation, and color change, and the animation made by the artist in the Spine tool can be accurately restored, which reduces repetitive work and greatly improves the efficiency of game development.
