Unity2D屏幕适配方案

看了cnblogs里的一篇文章，终于理解了Unity2D的摄像机系统：http://www.cnblogs.com/flyFreeZn/p/4073655.html

我根据他的方案，改写了两种适配方案：fixedWidth和fixedHeight，就是锁定其中一个变量来适配屏幕。

 using UnityEngine;

 using System.Collections;

 public class GameCamera : MonoBehaviour {

     public string scaleMode = "fixedWidth";

     public float designWidth = 9.6f;

     public float designHeight = 16f;

     // Use this for initialization

     void Start () {

         float aspectRatio = Screen.width * 1.0f / Screen.height;

         float orthographicSize = ;

         switch (scaleMode) {

         case "fixedWidth":

             orthographicSize = designWidth / ( * aspectRatio);

             break;

         case "fixedHeight":

             orthographicSize = designHeight / ;

             break;

         }

         this.GetComponent<Camera>().orthographicSize = orthographicSize;

         Debug.Log (orthographicSize);

     }

     // Update is called once per frame

     void Update () {

     }

 }

你可以修改设计尺寸，记住设计尺寸是通过1:100比例缩放后的。
