Are they not just F=-kx springs?
They are .. I was referring to the animation side of it .. writing something that stretched and squished in proportion etc .. my first attempt was in 3D .. What I’m saying is that the physics was easy but the animation was annoying

Depends on how you do it. If you do it right it should be pretty simple, as it is merely a linear scaling factor. Write everything in terms of spring turns per unit of length, then modify that by realizing that the number of turns on the current length of spring is fixed.

yup! that's what i ended up doing .. i just had to figure that out first lol

The F=-kr gets you the position of the bobs but doesn’t write the spring animation for you!

Maybe libraries like Bullet Physics https://github.com/bulletphysics/bullet … (C++) or https://github.com/kripken/ammo.js/ … (JS) could help? They can be used with OpenGL and
