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:

1. using UnityEngine;  
2. using System.Collections;  
3.   
4. public class Recompile : MonoBehaviour  
5. {  
6.   
7.     private string platform = string.Empty;  
8.     // Use this for initialization  
9.     void Start()  
10.     {  
11.         DebugPlatformMesaage();  
12.     }  
13.   
14.     void DebugPlatformMesaage()  
15.     {  
16.  
17. #if UNITY_EDITOR  
18.         platform = "hi,大家好,我是在unity编辑模式下";  
19. #elif UNITY_XBOX360  
20.        platform="hi，大家好,我在XBOX360平台";  
21. #elif UNITY_IPHONE  
22.        platform="hi，大家好,我是IPHONE平台";  
23. #elif UNITY_ANDROID  
24.        platform="hi，大家好,我是ANDROID平台";  
25. #elif UNITY_STANDALONE_OSX  
26.        platform="hi，大家好,我是OSX平台";  
27. #elif UNITY_STANDALONE_WIN  
28.        platform="hi，大家好,我是Windows平台";  
29. #endif  
30.         Debug.Log("Current Platform:" + platform);  
31.     }  
32. }  

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

1. //新加入的内容  
2. #if CUSTOM_ITF  
3.         customMsg = "我自己定义了预编译";  
4. #endif  
5.         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.
