To create a Bar Linkage Solver, you first need the right setup. This setup will include several fixed arms, Wheel Joints and a Piston (this requires a Spline ). Part A of the How to use will guide you through the process of creating this system.
Example of a system suitable for a Bar Linkage Solver.
First, add a Wheel Joint to each of the rotational points.
Make sure the Wheel Axis Direction of the Wheel Joints are aligned with the desired rotation.
After all Wheel Joints are added, create a Spline to control the range and postion of the Piston. Align the Spline Control Points to the Piston Rod. Holding V enables snapping to vertices in Unity.
Make sure the Spline is parented under the Piston. Your system is now set up to add a Bar Linkage Solver
