10.  
11.     private int m_Layer = 0;
12.  
13.  
14.     private Transform m_Transform = null;
15.  
16.  
17.     private Camera m_Camera = null;
18.  
19.  
20.     private Rect m_Range = new Rect(-1.0f, -1.0f, 1.0f, 1.0f);
21.  
22.  
23.     public void Initialize(int layer)
24.     {
25.         //

27.         transform.rotation = Quaternion.identity;
28.         transform.localScale = Vector3.one;
29.  
30.         //

32.  
33.         //
34.         m_Transform = gameObject.transform;
35.         m_Camera = (Camera)gameObject.AddComponent(typeof(Camera));
36.  
37.         //
38.         m_Transform.position = Vector3.zero;
39.         m_Transform.LookAt(Vector3.zero, Vector3.up);

51.     }
52.  
53.  
54.     public void SetClear(bool clear)

59.         }
60.         else
61.         {

63.         }
64.     }
65.  
66.  
67.     public void SetDepth(float depth)
68.     {
69.         m_Camera.depth = depth;
70.     }
71.  
72.  
73.     public void SetViewport(Rect range)
74.     {
75.  
76.  
77. #if UNITY_IPHONE
78.         m_Transform.position = new Vector3((range.xMin + range.xMax) / 2, (range.yMin + range.yMax) / 2, 0);
79. #else // Win32
80.         m_Transform.position = new Vector3((range.xMin + range.xMax + 1) / 2, (range.yMin + range.yMax - 1) / 2, 0);
81. #endif
82.  
83.         m_Camera.aspect = range.width / range.height;
84.         m_Camera.orthographicSize = range.height / 2;
85.  
86.         m_Range = range;
87.     }
88.  
89.  
90.     public Vector2 ScreenToWorld(Vector2 point)
91.     {
92.  
93.  
94.         return new Vector2(m_Range.x + point.x / Screen.width * m_Range.width, m_Range.y + point.y / Screen.height * m_Range.height);
95.  
96.     }
97. }
98.  
99.
