退出指针锁定控件three.js不工作

document.addEventListener('pointerlockchange', function () {
  isPointerLocked = document.pointerLockElement === renderer.domElement;
});

function animate() {
  requestAnimationFrame(animate);

  if (isPointerLocked) {
    // 执行鼠标事件操作
  }
  
  // 渲染场景
  renderer.render(scene, camera);
}

document.addEventListener('keydown', function (event) {
  if (event.key === 'Escape') {
    document.exitPointerLock();
    isPointerLocked = false;
  }
});
