Question Can't build a game through UnityEditor (error)

This is my code:

Code (CSharp):

1.  
2.     public static BuildTarget TargetPlatform = BuildTarget.StandaloneWindows;
3.     public static BuildOptions BuildOptions = BuildOptions.Development;
4.  
5. [MenuItem("Tools/Msf/Build Master + Spawner", false, 11)]
6. public static void BuildMasterAndSpawner(string path)
7.     {
8.         var masterScenes = new[]
9.         {
10.             QuickSetupRoot+ "/Scenes/SampleScene.unity"
11.         };
12.  
13.         BuildPipeline.BuildPlayer(masterScenes, path + "/SampleScene.exe", TargetPlatform, BuildOptions);
14.     }

And this is errors when I try to build:

Code (CSharp):

1. Assets\Scripts\MsfQuickBuild.cs(16,19): error CS0246: The type or namespace name 'BuildTarget' could not be found (are you missing a using directive or an assembly reference?)
2. Assets\Scripts\MsfQuickBuild.cs(22,19): error CS0246: The type or namespace name 'BuildOptions' could not be found (are you missing a using directive or an assembly reference?)
3. Assets\Scripts\MsfQuickBuild.cs(26,6): error CS0246: The type or namespace name 'MenuItemAttribute' could not be found (are you missing a using directive or an assembly reference?)
4. Assets\Scripts\MsfQuickBuild.cs(84,6): error CS0246: The type or namespace name 'MenuItem' could not be found (are you missing a using directive or an assembly reference?)

 

You have to put your script inside your "Editor" folder. "Assets/Editor/AudioSourceReplacement.cs" should do the trick.

 

Yes, this. 99% of build-y-ish scripts should go in an Editor/ folder.

Another way if only a tiny part of something is editor only is to guard it with

#if UNITY_EDITOR

so that all parts of it "drop out" when you build.
