驱动器编辑器

该编辑器允许您设置驱动器，根据其他属性计算属性值。换句话说，它们使一组源属性来 “驱动” 目标属性，因此可以作为手工动画属性的替代方法。

The user interface is largely the same as that of the Graph Editor, with two important differences:

• The Sidebar has an additional Drivers tab. This is where the source properties are brought together to calculate an intermediate value for the target property.

• The curve doesn’t represent the property’s value over time, but a mapping from the above intermediate value (X axis) to the final value (Y axis).
