Unity包含一个“平台相关的编译”功能。这包括一些预处理指令&＃xff0c;让你分割你的脚本编译和专为支持的平台之一执行代码段。
您可以Unity编辑器中运行代码&＃xff0c;这样你就可以专门为你的目标平台编译代码&＃xff0c;并在编辑器中测试&＃xff01;
平台#define指令
Unity支持脚本的平台#define指令如下&＃xff1a;
| Property: | Function: |
| UNITY_EDITOR | Unity编辑器 |
| UNITY_EDITOR_WIN | Windows 操作系统. |
| UNITY_EDITOR_OSX | macos操作系统 |
| UNITY_STANDALONE_OSX | 专门为macos&＃xff08;包括Universal, PPC&＃xff0c;Intel architectures&＃xff09;平台的定义 |
| UNITY_STANDALONE_WIN | 专门为windows平台的定义 |
| UNITY_STANDALONE_LINUX | 专门为Linux平台的定义 |
| UNITY_STANDALONE | 独立平台 (Mac OS X, Windows or Linux). |
| UNITY_WII | WII 游戏机平台 |
| UNITY_IOS | iOS系统平台 |

| UNITY_ANDROID | android系统平台 |
| UNITY_PS4 | ps4平台 |
| UNITY_SAMSUNGTV | 三星TV平台 |
| UNITY_XBOXONE | Xbox One 平台 |
| UNITY_TIZEN | Tizen 平台 |
| UNITY_TVOS | Apple TV 平台 |
| UNITY_WSA | #define directive for Universal Windows Platform. Additionally, NETFX_CORE is defined when compiling C# files against .NET Core and using .NET scripting backend. |
| UNITY_WSA_10_0 | #define directive for Universal Windows Platform. Additionally WINDOWS_UWP is defined when compiling C# files against .NET Core. |
| UNITY_WINRT | UNITY_WSA. |
| UNITY_WINRT_10_0 | UNITY_WSA_10_0 |
| UNITY_WEBGL | #define directive for WebGL. |
| UNITY_FACEBOOK | faceBook平台(WebGL or Windows standalone). |
| UNITY_ADS | 调用广告方法&＃xff0c;版本 5.2 以后 |
| UNITY_ANALYTICS | 调用unity分析服务&＃xff0c;版本5.2以后 |
| UNITY_ASSERTIONS | 控制指令的过程 |
Unity版本判定方式&＃xff1a;UNITY_X&＃xff0c;UNITY_X_Y&＃xff0c;UNITY_X_Y_Z例如&＃xff1a;
| UNITY_5 | Unity5版本,包含所有的5.x.y版本 |
| UNITY_5_0 | Unity5.0版本,包含所有的5.0.x版本 |
| UNITY_5_0_1 | Unity5.0.1版本 |
打包的时候&＃xff0c;选择File>Build Settings然后显示平台选择界面。
代码实例C#&＃xff1a;
// C#
using UnityEngine;
using System.Collections;
public class PlatformDefines : MonoBehaviour &＃xff5b;void Start () &＃xff5b;#if UNITY_EDITORDebug.Log("Unity Editor");#endif#if UNITY_IOSDebug.Log("Iphone");#endif#if UNITY_STANDALONE_OSXDebug.Log("Stand Alone OSX");#endif#if UNITY_STANDALONE_WINDebug.Log("Stand Alone Windows");#endif&＃xff5d;
&＃xff5d;
可以使用#if #elif
#if UNITY_EDITOR Debug.Log("Unity Editor");#elif UNITY_IOS Debug.Log("Unity iPhone"); #elseDebug.Log("Any other platform");
#endif
可以自定义宏定义&＃xff0c;打开Other Settings窗口&＃xff0c;选择Player Settings>Scripting Define Symbols
