類別: FixedPinJoint

定義於: constraint.ts:50

Pin joint connecting a body to a fixed world point.

備註

Creates a pendulum-like constraint where a point on the body is pinned to a fixed location in world space. The body can rotate around this point.

Uses Baumgarte stabilization to prevent drift.

範例

Create a pendulum

const bob = new Circle({ x: 0, y: 100 }, 20, 0, 10, false);
const joint = new FixedPinJoint(
  bob,
  { x: 0, y: 0 },  // Anchor on bob (center)
  { x: 0, y: 0 }   // World anchor (ceiling)
);
world.addRigidBody('bob', bob);
world.addConstraint(joint);
