1、Canvas的属性配置

2、Canvas Scaler的属性配置

3、根据不同的屏幕的比例动态修改缩放基准

1 void Start ()    2     {   3         float standard_width = 960f;        //初始宽度   4         float standard_height = 640f;       //初始高度   5         float device_width = 0f;                //当前设备宽度   6         float device_height = 0f;               //当前设备高度   7         float adjustor = 0f;         //屏幕矫正比例   8         //获取设备宽高   9         device_width = Screen.width;  10         device_height = Screen.height;  11         //计算宽高比例  12         float standard_aspect = standard_width / standard_height;  13         float device_aspect = device_width / device_height;  14         //计算矫正比例  15         if (device_aspect < standard_aspect)  16         {  17             adjustor = standard_aspect / device_aspect;  18         }  19   20         CanvasScaler canvasScalerTemp = transform.GetComponent
     
      ();  21         if (adjustor == 0)  22         {  23             canvasScalerTemp.matchWidthOrHeight = 1;  24         }  25         else  26         {  27             canvasScalerTemp.matchWidthOrHeight = 0;  28         }  29     }
     

将脚本挂在画布控件上。
