PointToPointConstraint class

Connects two bodies at given offset points. @example const bodyA = Body({ mass: 1 }) const bodyB = Body({ mass: 1 }) bodyA.position.set(-1, 0, 0) bodyB.position.set(1, 0, 0) bodyA.addShape(shapeA) bodyB.addShape(shapeB) world.addBody(bodyA) world.addBody(bodyB) const localPivotA = Vec3(1, 0, 0) const localPivotB = Vec3(-1, 0, 0) const constraint = PointToPointConstraint(bodyA, localPivotA, bodyB, localPivotB) world.addConstraint(constraint)

PointToPointConstraint(Body bodyA, Body bodyB, [Vec3? pivotA, Vec3? pivotB, double maxForce = 1e6])
pivotA The point relative to the center of mass of bodyA which bodyA is constrained to. bodyB Body that will be constrained in a similar way to the same point as bodyA. We will therefore get a link between bodyA and bodyB. If not specified, bodyA will be constrained to a static point. pivotB The point relative to the center of mass of bodyB which bodyB is constrained to. maxForce The maximum force that should be applied to constrain the bodies.
