本文介绍了Unity3D中根动画的工作原理，包括U3DrootMotion和BodyTransform的概念。BodyTransform代表角色的质量中心，用于Mecanim的重定向引擎。RootTransform是在运行时计算的BodyTransform在Y平面上的投影，并应用于游戏对象使其移动。

U3D rootMotion

Body Transform

The Body Transform is the mass center of the character. It is used in Mecanim’s retargeting engine and provides the most stable displacement model. The Body Orientation is an average of the lower and upper body orientation relative to the Avatar T-Pose.

The Body Transform and Orientation are stored in the Animation Clip (using the Muscle definitions set up in the Avatar). They are the only world-space curves stored in the Animation Clip. Everything else: muscle curves and IK goals (Hands and Feet) are stored relative to the body transform.

Root Transform

The Root Transform is a projection on the Y plane of the Body Transform and is computed at runtime. At every frame, a change in the Root Transform is computed. This change in transform is then applied to the Game Object to make it move.

总结：根动画是不断累加的，动画集内的位移是循环的（每次循环起始都归0）。
