Unity includes a feature named "Platform Dependent Compilation". This consists of some preprocessor directives that let you divide your scripts to compile and execute a section of code exclusively for one of the supported platforms.
Unity包含一个名为"平台依赖编译"的功能。他包含一些预处理指令,能够让你专门在一个支持的平台上分开编译和执行某一段代码。
Furthermore, you can run this code within the Editor, so you can compile the code specifically for your mobile/console and test it in the Editor!
此外,你可以在编辑器中运行此代码,这样你就可以在mobile/console上编译此代码,并在编辑器中对其进行测试!
The platform defines that Unity supports for your scripts are:
Unity支持的平台定义脚本是:
Note: These defines were introduced at version 3.0.
注意:这些定义在3.0版本时被引入。
Also you can compile code selectively depending on the version of the engine you are working on. Currently the supported ones are:
你可以选择性的编译代码,这取决于你正在使用的引擎的版本。目前支持的有:
Note: For versions before 2.6.0 there are no platform defines as this feature was first introduced in that version.
注意:之前2.6.0版本中没有平台定义,此功能是在该版本中首次引入。
We are going to show a small example of how to use the precompiled code. This will simply print a message that depends on the platform you have selected to build your target.
我们要展示如何使用预编译代码的一个小例子,这将根据你选择要生成目标平台输出一条消息。
First of all, select the platform you want to test your code against by clicking on File -> Build Settings. This will bring the build settings window to select your target platform.
首先,通过单击File->Bulid Settings选择你想测试你的代码的目标平台,将需要在设置窗口里选择你的目标平台。
Select the platform you want to test your precompiled code against and press the Switch Editor button to tell Unity which platform you are targeting.
选择你想测试的预编译代码,按下Switch Editor按钮告诉Unity你要测试的目标平台。
Create a script and copy/paste this code:
创建一个脚本,复制/粘贴这段代码:
JavaScript Example:
function Awake() { #if UNITY_EDITOR Debug.Log("Unity Editor"); #endif #if UNITY_IPHONE Debug.Log("Iphone"); #endif #if UNITY_STANDALONE_OSX Debug.Log("Stand Alone OSX"); #endif #if UNITY_STANDALONE_WIN Debug.Log("Stand Alone Windows"); #endif }
C# Example:
using UnityEngine;using System.Collections;public class PlatformDefines : MonoBehaviour { void Start () { #if UNITY_EDITOR Debug.Log("Unity Editor"); #endif #if UNITY_IPHONE Debug.Log("Iphone"); #endif #if UNITY_STANDALONE_OSX Debug.Log("Stand Alone OSX"); #endif #if UNITY_STANDALONE_WIN Debug.Log("Stand Alone Windows"); #endif } }
Boo Example:
import UnityEngineclass PlatformDefines (MonoBehaviour): def Start (): ifdef UNITY_EDITOR: Debug.Log("Unity Editor") ifdef UNITY_IPHONE: Debug.Log("IPhone") ifdef UNITY_STANDALONE_OSX: Debug.Log("Stand Alone OSX") ifdef not UNITY_IPHONE: Debug.Log("not an iPhone")
Then, depending on which platform you selected, one of the messages will get printed on the Unity console when you press play.
然后,根据你选择的平台,当按下Play时,Unity会在控制台中输出一条消息。
