Made this as a proof-of-concept for a softbody simulation I am working on, as well as for a 'wiggly animal' game. Variable 'K' is the spring constant (how tough the spring is.) Elasticity is how 'bouncy' the spring is.
Everything by me. Formulas and solvers for inertia, dampening, tension, elasticity, mass, and others were all made by me through trial and error. !!!This is a WORK IN PROGRESS!!!
