public Class DistanceJoint

Class Inheritance

extends Joint

java.lang.Object
com.badlogic.gdx.physics.box2d.Joint
com.badlogic.gdx.physics.box2d.joints.DistanceJoint

Imports

com.badlogic.gdx.math.Vector2, com.badlogic.gdx.physics.box2d.Joint, .World

A distance joint constrains two points on two bodies to remain at a fixed distance from each other. You can view this as a massless, rigid rod.
