Tether constraints for ropes with no fixed points

[khalvr]

That actually sounds vaguely similar to the current solution i have with spring joints enforcing the distance, except that it's a per-particle constraint (if i understand correctly). I'm using particle handles since otherwise i had the issue with particles very often getting stuck inside/behind colliders (including getting stuck underneath the 1m thick floor), and since i'm developing for a contest scenario, anything that might interrupt the process is a no-go. Thanks though!
