Easy Bounce for After Effects Pro vs Free
https://aescripts.com/easy-bounce
Create bouncing animations the easy way! Just roughly keyframe the motion path you'd like, and let Easy Bounce take care of the rest.
In a nutshell, the free version only supports bouncing off the ground, whereas the Pro version also lets you bounce off the walls. The free version can also only change the position keyframes of a layer, whereas the pro version can adjust other keyframes too. Let’s say for example that you keyframed the rotation or shape paths – Easy Bounce Pro will also shift these other keyframes to fit the new timing. What’s more, the Pro version can squash your layers when they hit the ground and offers advanced options to control gravity, for example.
