## About this tutorial

In this tutorial, you will learn how to create a 3D interactive/reactive scene with spheres using the Mouse Hover event to trigger state transitions in other objects using Spline.

Update: Spline has improved a lot since this tutorial was published. Transitions are now actions that can be attached to Events. "Hard Reset All" is now "Reset Transform."
