After I make my master cable which has the two connectors, how can I safely create a prefab that I can re-use over and over?  The cables I'm making also have custom snap functions that connect them to other gameobjects,  so it's important that both ends are able to be freely manipulated by the player in VR.  The goal here is to have different length & color coded prefab cables for the player to use.  With each level, I hope to be able to just drop them in the heirachy going forward.

Note this assumes you don't need the rope to be a straight line at rest, if you need it, you will need to reposition the cable connectors as well.

In case you need to create arbitrarily shaped cables connecting objects at runtime that might be at arbitrary positions/distances from each other, you might want to create your ropes ...

Thanks. I'll look deeper into this.

Quote:Just creating a prefab the usual way should work. Just make sure that you instantiate your prefabs inside a ObiSolver at runtime, otherwise they won't be simulated or rendered.

 Just to make sure I fully understand, do you mean I should place the end connectors as children under ObiSolver?  And then drag ObiSolver to the prefab folder?

Quote:No, I meant that the rope itself must be a child (at any nesting level) of a ObiSolver. It's irrelevant whether the end connectors are or not, since they're regular rigidbodies and hence not simulated by Obi.


What do you mean by this? there's no such thing as a specific "prefab folder" in Unity, you can have prefabs anywhere in your project. I just meant that when instantiating your rope prefab, you should make sure it's inside a solver's hierarchy.

Sorry to cause any confusion.  I meant "my" prefab folder.   What I wanted to do was group together both my end connectors and the rope as one prefab.  Just like a real cable.  Since I will need sometimes 10 or more of these cables in a scene.  It would be amazing if I didn't need to keep reconfiguring the attachments -- if possible.
