Creating drivers

The procedure for creating drivers is very similar to the one for creating animations. While the animation time is the only input of animation curves, drivers can depend on one or more of the following:

• The result of Python expressions
• Any property that can be animated
• The transform channels of objects
• The difference in rotations between objects
• The distance between objects

When we create a driver, we must specify at least one input. In this section, we will learn how to set up a simple wheel by creating new drivers with the user interface.

There are a few shortcuts for creating drivers quickly.

Let’s take a look at an example to understand these shortcuts. Suppose that, to animate a wheel, we want an object’s Location Y to drive its Rotation X channel. We can set this up for Blender’s default cube:

1. Open Blender or go back to the default scene via File...
