This is what i have done for my rope and it works really good. Thoo I
have big problems with making the rope stable. It tends to explode when
it's streched, the ball joint gets pulled apart.
I actually found the fixed joint to be most stable. I have implemented
my own version of the fixed joint, where i have added the possibility to
set the CFM and ERP individually for linear and angular motion in each
axes. This way i can simulate ropes with different strecthing, bending
and twisting properties. I have limited testing with this joint, but
from what i have testet i have gotten the best result from this joint.
The big setback is that too many joints really kills the performance
since im actually setting 0 dof between the capsules jointed together.
