The CreateHinge method is a static method of the PhysicsJoint class in the Sandbox.Physics namespace. It is used to create a hinge joint between two physics points. A hinge joint allows two objects to rotate around a common axis, similar to the hinge of a door.

To use the CreateHinge method, you need to provide two PhysicsPoint objects as parameters. These points represent the locations on the two bodies where the hinge joint will be attached.

Example usage:

PhysicsPoint pointA = new PhysicsPoint();
PhysicsPoint pointB = new PhysicsPoint();
HingeJoint hinge = PhysicsJoint.CreateHinge(pointA, pointB);

In this example, pointA and pointB are the two points on the respective bodies where the hinge joint is created. The method returns a HingeJoint object that represents the created joint.
