如何在ThreeJS中点击移动设备？

document.addEventListener('touchstart', onTouchStart, false);

function onTouchStart(event) {
  var touch = event.touches[0];
  var x = touch.clientX;
  var y = touch.clientY;
  
  // 在这里处理点击事件
}

function onTouchStart(event) {
  var touch = event.touches[0];
  var x = touch.clientX;
  var y = touch.clientY;
  
  var mouse = new THREE.Vector2();
  mouse.x = (x / window.innerWidth) * 2 - 1;
  mouse.y = -(y / window.innerHeight) * 2 + 1;
  
  var raycaster = new THREE.Raycaster();
  raycaster.setFromCamera(mouse, camera);
  
  // 在这里处理点击事件
}

function onTouchStart(event) {
  var touch = event.touches[0];
  var x = touch.clientX;
  var y = touch.clientY;
  
  var mouse = new THREE.Vector2();
  mouse.x = (x / window.innerWidth) * 2 - 1;
  mouse.y = -(y / window.innerHeight) * 2 + 1;
  
  var raycaster = new THREE.Raycaster();
  raycaster.setFromCamera(mouse, camera);
  
  var intersects = raycaster.intersectObjects(objects);
  
  if (intersects.length > 0) {
    // 点击到物体，执行相应操作
    var clickedObject = intersects[0].object;
    // ...
  }
}
