My previous answer was deleted by ?...

And how can we do that in 3D ??

I don't see any DampedSpringJoint3D in Godot ?... Especially if we want to work with JOLT Physics. Is there any possiblity to do the same thing ?

it is so close to the first question, 2D to 3D, just a generalization of the question. According to me, it isn't worth pollute your website with another quastion as it is a logical extension 2D to 3D. Really it is the "same" question. I didn't see that you deleted my answer. What a pity, really, you show a psychorigidity unbelievable. You could make an answer and inform that it should be in another question, but for 2D -> 3D, your delete is pitiful. I am engineer and also associate professor in an engineering school, and if I was so psychorigid I imagine that students would be disappointed.
