网站建设资费怎么做网站的浏览量统计
错误示范：
一开始把移动的代码写到update里去了，发现物体老是掉(总之移动非常不流畅，体验感很差）
void Update(){Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);if (Physics.Raycast(ray, out RaycastHit hit, Mathf.Infinity, LayerMask.GetMask("Interactables"))){if (Input.GetMouseButton(0)){hit.transform.position=ScreenToWorldPos(Input.mousePosition);}}}public Vector3 ScreenToWorldPos(Vector3 screenPosition){Vector3 targetScreenPos = Camera.main.WorldToScreenPoint(depthReference.position);float depth = targetScreenPos.z;screenPosition.z = depth;Vector3 worldPosition = Camera.main.ScreenToWorldPoint(screenPosition);return worldPosition;}
修改：
把移动的代码改到协程里更新就能流畅移动了
void Update(){Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);if (Physics.Raycast(ray, out RaycastHit hit, Mathf.Infinity, LayerMask.GetMask("Interactables"))){if (Input.GetMouseButtonDown(0)){StartCoroutine(Move(hit.collider.transform));}}}IEnumerator Move(Transform hitobj){while (true){if (Input.GetMouseButton(0) ){Vector3 targetPosition = ScreenToWorldPos(Input.mousePosition);hitobj.position = targetPosition;}yield return null;}}public Vector3 ScreenToWorldPos(Vector3 screenPosition){Vector3 targetScreenPos = Camera.main.WorldToScreenPoint(depthReference.position);float depth = targetScreenPos.z;screenPosition.z = depth;Vector3 worldPosition = Camera.main.ScreenToWorldPoint(screenPosition);return worldPosition;}问了一下gpt大概是这个原理，说白了就是鼠标输入不是逐帧更新的，它一直在更新，update执行速度跟不上，协程的执行速度跟得上（但是我还是没明白为啥协程比update快，就算update重新启动，可是执行的代码都是一样的，要么就是因为update每次都要重新进行射线检测拖慢了速度吧）
