Attaching actors to players, or other actors and applying physics

Tell me at least what methods you tried to connect them

I am currently trying to implement something similar, except that the structure should not depend on one parent block from which construction begins, my idea is closer to space engineers

Now I have already tried two connection methods:

  • auto-welding - which does not suit me somewhat due to the strict dependence of the child - parent (there can be only 1 parent)
  • physical constraints - makes it possible to connect blocks without strict adherence to the child-parent dependency, but there is a problem with insufficient structural rigidity (begins to bend when connecting 6+ blocks)
