Class GearConstraint

Constrains the angle of two bodies to each other to be equal. If a gear ratio is not one, the angle of bodyA must be a multiple of the angle of bodyB.

Example

var constraint = new GearConstraint(bodyA, bodyB);
    world.addConstraint(constraint);

Example

var constraint = new GearConstraint(bodyA, bodyB, {
        ratio: 2,
        maxTorque: 1000
    });
    world.addConstraint(constraint);
