2D joints

Approaches and techniques for working with 2D jointsA physics component allowing a dynamic connection between Rigidbody components, usually allowing some degree of movement such as a hinge. More info

Page Description
Introduction to 2D joints Understand the fundamental concepts of 2D joints.
2D joint constraints Understand the constraints of using 2D joints.
Distance Joint 2D Techinques and resources for working with Distance Joint 2D components.
Fixed Joint 2DA 2D joint type which is completely constrained, allowing two objects to be held together. Implemented as a spring so some small motion may still occur. More info

Friction Joint 2D Techinques and resources for working with Friction Joint 2D components.
Hinge Joint 2D Techinques and resources for working with Hinge JointA joint that groups together two Rigidbody components, constraining them to move like they are connected by a hinge. It is perfect for doors, but can also be used to model chains, pendulums and so on. More info

2D components.
Relative Joint 2DA 2D joint that allows two game objects controlled by Rigidbody physics to maintain in a position based on each other’s location. Use this joint to keep two objects offset from each other, at a position and angle you decide More info

Slider Joint 2D Techinques and resources for working with Slider Joint 2D components.
Spring Joint 2D Techinques and resources for working with Spring JointA joint type that connects two Rigidbody components together but allows the distance between them to change as though they were connected by a spring. More info
