Unity3D有一个叫做”live recompile”的功能，即在编辑器处于播放状态时修改脚本代码或替换托管dll等操作时，当场触发重新编译生成项目脚本assembly，并会进行重新加载操作，然而，这个功能很多时候并不能保证重加载后的代码逻辑依然能正常运行，轻则报错，重则卡死。经过博主测试发现，Unity在重加载assembly后，会清空类实例部分成员变量的值（如在Awake中new出的数组对象等），且不负责还原。最终，为了避免由于此导致的问题，采取了一种回避的手段：通过Editor脚本方式检测是否在播放状态时触发了脚本编译，是的话立即停止播放，代码如下：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 | // Cape Guy, 2015. Use at your own risk.using UnityEngine;using UnityEditor;/// <summary>/// This script exits play mode whenever script compilation is detected during an editor update./// </summary>[InitializeOnLoad] // Make static initialiser be called as soon as the scripts are initialised in the editor (rather than just in play mode).public class ExitPlayModeOnScriptCompile { // Static initialiser called by Unity Editor whenever scripts are loaded (editor or play mode) static ExitPlayModeOnScriptCompile () { Unused (_instance); _instance = new ExitPlayModeOnScriptCompile (); } private ExitPlayModeOnScriptCompile () { EditorApplication.update += OnEditorUpdate; } ~ExitPlayModeOnScriptCompile () { EditorApplication.update -= OnEditorUpdate; // Silence the unused variable warning with an if. _instance = null; } // Called each time the editor updates. private static void OnEditorUpdate () { if (EditorApplication.isPlaying && EditorApplication.isCompiling) { Debug.Log ("Exiting play mode due to script compilation."); EditorApplication.isPlaying = false; } } // Used to silence the 'is assigned by its value is never used' warning for _instance. private static void Unused<T> (T unusedVariable) {} private static ExitPlayModeOnScriptCompile _instance = null;} |
