Unity运行平台判断

unity是跨平台的，一般都是在PC ，Andriod 和IOS用的比较多。

平台判断代码：

    #if UNITY_ANDROID  
        Debug.Log("这里是安卓设备");  
    #endif  
     
    #if UNITY_IPHONE  
            Debug.Log("这里是苹果设备");  
    #endif  
     
    #if UNITY_STANDALONE_WIN  
            Debug.Log("我是从Windows的电脑上运行的");  
    #endif  

或者是写这种：

   if (Application.platform == RuntimePlatform.Android || 
        Application.platform == RuntimePlatform.IPhonePlayer)
   {


   }

名称  描写叙述 UNITY_EDITOR Define for calling Unity Editor scripts from your game code. UNITY_STANDALONE_OSX Platform define for compiling/executing code specifically for Mac OS (This includes Universal, PPC and Intel architectures). UNITY_DASHBOARD_WIDGET Platform define when creating code for Mac OS dashboard widgets. UNITY_STANDALONE_WIN Use this when you want to compile/execute code for Windows stand alone applications. UNITY_STANDALONE_LINUX Use this when you want to compile/execute code for Linux stand alone applications. UNITY_STANDALONE Use this to compile/execute code for any standalone platform (Mac, Windows or Linux). UNITY_WEBPLAYER Platform define for web player content (this includes Windows and Mac Web player executables). UNITY_WII Platform define for compiling/executing code for the Wii console. UNITY_IPHONE Platform define for compiling/executing code for the iPhone platform. UNITY_ANDROID Platform define for the Android platform. UNITY_PS3 Platform define for running PlayStation 3 code. UNITY_XBOX360 Platform define for executing Xbox 360 code. UNITY_NACL Platform define when compiling code for Google native client (this will be set additionally to UNITY_WEBPLAYER). UNITY_FLASH Platform define when compiling code for Adobe Flash.

 

   以后我们能够依据如上宏定义就能够去轻而易举的非常easy去在我们代码中增加推断了。我举个简单样例，例如以下:

 using UnityEngine;
 using System.Collections;

 public class Recompile : MonoBehaviour
 {

     private string platform = string.Empty;
     // Use this for initialization
     void Start()
     {
         DebugPlatformMesaage();
     }

     void DebugPlatformMesaage()
     {

 #if UNITY_EDITOR
         platform = "hi,大家好,我是在unity编辑模式下";
 #elif UNITY_XBOX360
        platform="hi，大家好,我在XBOX360平台";
 #elif UNITY_IPHONE
        platform="hi，大家好,我是IPHONE平台";
 #elif UNITY_ANDROID
        platform="hi，大家好,我是ANDROID平台";
 #elif UNITY_STANDALONE_OSX
        platform="hi，大家好,我是OSX平台";
 #elif UNITY_STANDALONE_WIN
        platform="hi，大家好,我是Windows平台";
 #endif
         Debug.Log("Current Platform:" + platform);
     }
 }

上面假设我是在Editor状态下的话，就能看见打印出:   

 

 

我们也能够自定义宏定义，在PlayerSetting中定义：

 

比如我在上面圈起来的地方填写一个CUSTOM_ITF这个预编译指令。然后在DebugPlatformMesaage函数尾部增加这句话

 //新加入的内容
 #if CUSTOM_ITF
         customMsg = "我自己定义了预编译";
 #endif
         Debug.Log(customMsg);

然后我们执行看下，你就能在控制台看见我们输出的信息了：

 

    当我们把我们自己定义的宏定义给去掉的时候，我们打印的信息就不会出来。

 

除了这些，unity中还有各个版本号的宏定义，一般开发插件的大牛都会用到。

 

UNITY_2_6	Platform define for the major version of Unity 2.6.
UNITY_2_6_1	Platform define for specific version 1 from the major release 2.6.
UNITY_3_0	Platform define for the major version of Unity 3.0.
UNITY_3_0_0	Platform define for the specific version 0 of Unity 3.0.
UNITY_3_1	Platform define for major version of Unity 3.1.
UNITY_3_2	Platform define for major version of Unity 3.2.
UNITY_3_3	Platform define for major version of Unity 3.3.
UNITY_3_4	Platform define for major version of Unity 3.4.
UNITY_3_5	Platform define for major version of Unity 3.5.
UNITY_4_0	Platform define for major version of Unity 4.0.
UNITY_4_0_1	Platform define for major version of Unity 4.0.1.
UNITY_4_1	Platform define for major version of Unity 4.1.
UNITY_4_2	Platform define for major version of Unity 4.2.
