Question by sharahamo · Aug 09, 2017 at 12:05 PM · 2d gamerigidbody2dspringjointfixedjointconnectedbody

Physics for multiple connections - advice needed

I am developing a game with system like the following, and I do not know what exactly the kind of connection I need for the system:

alt text

What I am trying to do is:

  1. BirdLeft to be connected to RopeLeft and Bird Right to be connected to the RopeRight

  2. Both RopeLeft and RopeRight are connected to the Nest

  3. Both RopeRight and RopeLeft act like a spring, which can be shortened and lengthened (in x direction only) based on my input. For example, if I shortened the RopeRight, RopeLeft will be lengthened and the Nest will move to the right.

  4. Both BirdLeft and BirdRight will stay in place.

What I need advice on is:

  1. What kinds of connected (fixed connection, spring connection?) do I need on each body, and where?

  2. How to make the rope acts as a spring?
