If you want to define an animation path for an object, we recommend that first of all you create the path as a Spline object. This has an advantage over the keyframe method in that you can create BSpline paths and use tools such as the magnet. You can also use closed splines for creating cyclic motion — a difficult task using keyframes.

如果要为对象定义动画路径，建议首先将路径创建为样条对象。这比关键帧方法有一个优势，因为您可以创建 b 样条路径并使用磁铁之类的工具。您还可以使用闭合样条来创建循环运动ーー使用关键帧是一项困难的任务。
