Unity 2D两种常用判断点击的方法

1 RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero); 
2 
3 if(hit.collider != null)
5 { 
7 　　Debug.Log ("Target Position: " + hit.collider.gameObject.transform.position);
8 　　//and do what you want
9 }

1 Collider2D[] col = Physics2D.OverlapPointAll(Camera.main.ScreenToWorldPoint(Input.mousePosition));
2  
3 if(col.Length > 0)
4 {
5     foreach(Collider2D c in col)
6     {
7          //do what you want
8     }
9 }
