# Sandbox.Physics.SpringJoint

A rope-like constraint that is has springy/bouncy.

- Kind: class
- Namespace: `Sandbox.Physics`
- Assembly: `Sandbox.Engine`
- Inherits: [Sandbox.Physics.PhysicsJoint](/api/Sandbox.Physics.PhysicsJoint)

## Properties

- [`MaxForce`](/api/Sandbox.Physics.SpringJoint/MaxForce): Maximum force it should be allowed to go. Set to zero to only allow stretching.
- [`MaxLength`](/api/Sandbox.Physics.SpringJoint/MaxLength): Maximum length it should be allowed to go
- [`MinForce`](/api/Sandbox.Physics.SpringJoint/MinForce): Minimum force it should be allowed to go.
- [`MinLength`](/api/Sandbox.Physics.SpringJoint/MinLength): Minimum length it should be allowed to go. At which point it acts a bit like a rod.
- [`ReferenceMass`](/api/Sandbox.Physics.SpringJoint/ReferenceMass)
- [`SpringLinear`](/api/Sandbox.Physics.SpringJoint/SpringLinear): How springy and tight the joint will be
