Thank you!
About bounciness, I think I showcase it in some of my YouTube videos. Don’t remember which one exactly: https://www.youtube.com/@martindzejky
But TLDR I have a “squash” component which does spring-based physics animation via code and it sets the scale of a node (i.e. the sprite). I can trigger the squash animation from anywhere by calling its “squash()” function. Its source code is here: https://github.com/martindzejky/pigeon-in-town/blob/master/scripts/components/squash.gd
