Modify “amp” for the amplitude or how much bounce is present. Nonetheless, it’s a great helper and I use it all the time. Although I’ve made a slight modification to it to make it a little more user friendly, it’s nothing that I will lay claim to as my own code. The seeds were certainly planted by the great Dan Ebberts, and then a modified version was posted on. It’s very cool! This expression is a bit of a community effort.
This also accounts for scalar or array values, so you’ll find that this expression works just as well on 2D rotation as it does on 3D position. Being that true “velocity” includes the vector (or traveling direction in 3D space), the bounce happens in whatever direction the object is traveling. Intertial Bounce v1.2Įssentially, Inertial Bounce creates a bouncing motion of any parameter from one keyframe to the next, based on its velocity. These are expressions I use in just about every project, and I consider them to be incredible workflow enhancements.ĭownload the AE Presets 1. Therefore, I’d like to share with you my 5 favorite expressions.
I realize that expressions can be daunting, and some would rather copy and past useful code rather than learn the language.
