プロジェクトで良く切り替えるScriptDefineSymbolのグループをEditorToolからサクっと切り替えられると便利

DefineSymbolSwitcher.cs

using UnityEditor;

public static class DefineSymbolSwitcher
{
	private static BuildTargetGroup CurrentPlatform = EditorUserBuildSettings.selectedBuildTargetGroup;

	private static void Log() {
		UnityEngine.Debug.Log(string.Format("done! Platform: {0}, DefineSymbol: {1}",
			CurrentPlatform, PlayerSettings.GetScriptingDefineSymbolsForGroup(CurrentPlatform)));
	}

	#region DEBUG
	[MenuItem("MyProject/SwitchDefineSymbol/CurrentPlatform/DEBUG;")]
	public static void Debug()
	{
		PlayerSettings.SetScriptingDefineSymbolsForGroup(CurrentPlatform, string.Format("{0};",
			"DEBUG"));
		Log();
	}

	[MenuItem("MyProject/SwitchDefineSymbol/CurrentPlatform/DEBUG;AB;")]
	public static void DebugAB()
	{
		PlayerSettings.SetScriptingDefineSymbolsForGroup(CurrentPlatform, string.Format("{0};{1};",
			"DEBUG", "AB"));
		Log();
	}
	#endregion
}

indent崩れてるの渋い
