Unity2D OnTriggerExit 會觸發不了 OnTriggerExit Cant run

private void OnTriggerStay2D(Collider2D other) { if (other.tag == "moveable") {

         if (choosemove == false)
         {
             hit = Physics2D.Raycast(screenPos, Vector2.zero, 100, 256);
             fastsetG = GameObject.Find(hit.transform.name);

         }
         if (hit.transform.tag== "moveable")
         {

             if (Input.touchCount > 0)
             {
                 choosemove = true;
             }
                 if (Input.touchCount == 0)
             {
                 choosemove = false;
             }



             if (choosemove)
             {
                 
                 fastsetG.transform.position = new Vector2(screenPos.x, screenPos.y);

             }
           
         }
     }
 }

private void OnTriggerExit2D(Collider2D other) { if (hit.transform.tag == "moveable") { mousePos = new Vector3(); screenPos = new Vector3(); choosemove = false; } } 我要的效果是 如果moveable標籤的物件移出trigger會取消控制
但是測試出來是如果物體移動快速離開則程式判斷不到 物體還是可以控制 但是慢慢地移出Trigger有50%以上的機率感應的到 可以執行 I want the object in my trigger and I touch it ,I can control its position. And the object leave the trigger,it would out of control; Mostly I move the object fast to leave trigger,the onTriggerExit() not run the code . if I move the object slowly to leave trigger,the onTriggerExit() has 50%percent run the code .
