Class DistanceConstraint

Constraint that tries to keep the distance between two bodies constant.

Example

// If distance is not given as an option, then the current distance between the bodies is used.
    // In this example, the bodies will be constrained to have a distance of 2 between their centers.
    var bodyA = new Body({ mass: 1, position: [-1, 0] });
    var bodyB = new Body({ mass: 1, position: [1, 0] });
    var constraint = new DistanceConstraint(bodyA, bodyB);
    world.addConstraint(constraint);
Copy

Example

// Manually set the distance and anchors
    var constraint = new DistanceConstraint(bodyA, bodyB, {
        distance: 1,          // Distance to keep between the points
        localAnchorA: [1, 0], // Point on bodyA
        localAnchorB: [-1, 0] // Point on bodyB
    });
    world.addConstraint(constraint);
