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：

1.  

2. #if UNITY_ANDROID

3. Debug.Log("这里是安卓设备");

4. #endif

5.  

6. #if UNITY_IPHONE

7. Debug.Log("这里是苹果设备");

8. #endif

9.  

10. #if UNITY_STANDALONE_WIN

11. Debug.Log("我是从Windows的电脑上运行的");

12. #endif

或者是写这种：

1.  

2. if (Application.platform == RuntimePlatform.Android ||

3. Application.platform == RuntimePlatform.IPhonePlayer)

4. {

5.  
6.  

7. }

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.
