推荐答案
在使用任何Unity API之前，检查API名称空间非常重要.如果名称空间来自UnityEditor，则只能在编辑器中使用.这用于制作编辑器插件.您不能在构建中使用它，并且在为任何平台构建时都会抛出错误.
Before using any Unity API, it is very important to check the API namespace. If the namespace is from UnityEditor then it is only meant to work in the Editor only. This is used to make an Editor plugin. You can't use it in a build and it will throw an error when building for any platform.
根据文档 AssetDatabase 和
According the docs, AssetDatabase and EditorUtility class are from the UnityEditor namespace.
您必须重新设计游戏才能使用GetAssetPath功能.您绝对可以在没有该功能的情况下制作游戏.我不清楚您在做什么，但您应该查看 Resources 类.这将帮助您在运行时加载GameObject.
You have to re-design your game to work without the GetAssetPath function. You can definitely make a game without that function. I can't tell what you are doing but you should look into the Resources class. This will help you load your GameObjects during run-time.
要解决当前的问题，
替换
using UnityEditor;
使用
#if UNITY_EDITOR
using UnityEditor;
#endif
然后替换
objMaterial.textureName = EditorUtility.GetAssetPath(mats[material].mainTexture);
使用
objMaterial.textureName = "";
#if UNITY_EDITOR
objMaterial.textureName = EditorUtility.GetAssetPath(mats[material].mainTexture);
#endif
您还可以将Menu脚本放在Assets/Editor目录中的文件夹中，但是请理解，这不能解决代码无法在内部版本中工作的问题.它将仅允许您构建项目，而不会在您的问题中出现这些错误. UnityEditor名称空间中的类仅用于Editor插件.
You can also put your Menu script in a folder in the Assets/Editor directory but please understand that this does not solve the problem that your code won't work in a build. It will only allow your project to build without those errors in your question. The classes from the UnityEditor namespace are only used for Editor plugin.
