I'm connecting two moving rigidbodies using a spring joint in Unity. Between them, a rope will be rendered using a line renderer and I want it to move realistically as the joints move, without physics.
I've read about verlet integration, but only found examples where one point moves, and the other one is calculated, for example a guy with a grappling gun, swinging back and forth.
Here's the current implementation with spring joints.
The second image shows a nice and smooth verlet rope with a line renderer. It's a little too lenient, but looks good. As this doesn't use physics, it doesn't let me move the object or affect the ship, for example if it was stuck on something.
How do I make an elastic rope like the second image, between the spring joints, without the physics engine?
