Errors building with custom action script

Hi everyone!

I have a problem when I try to build a project that uses a custom

I created the script following the "Writing a custom action" tutorial and
everything's works fine when I try the game in Unity, but when I compile the
project I get the following errors:

- error CS0115: `AC.ActionMyAnimation.ShowGUI()' is marked as an override
but no suitable method found to override;

- error CS0246: The type or namespace name `UnityEditor' could not be
found. Are you missing a using directive or an assembly reference?

It looks like it can't find the reference to UnityEditor, but I don't know

The build settings are:

- target platform: windows;

- architecture: x86 (tried also x86_64 with the same result)

- development build: unchecked

Here's the code of the script:

using UnityEngine;

using System.Collections;

using UnityEditor;

namespace AC



public class ActionMyAnimation :


        // Declare variables here

        public Animator animator = null;

        public ActionMyAnimation()


this.isDisplayed = true;

            category = ActionCategory.Object;

            title = "My Animation";

            animator = new Animator();


        public override void ShowGUI()


            animator = (Animator)EditorGUILayout.ObjectField("Animator :",
animator, animator.GetType(), true, null);



        override public float Run ()


                  //do stuff




Anyone knows why I get this problem?




  • I use Unity 5.3.1f1 Perosnal and AC 1.50g,

    The ShowGUI() function requires UnityEditor's namespace, but the Action class itself cannot live in an Editor folder - meaning any reference to UnityEditor and it's API must live inside #if UNITY_EDITOR directives.

    This is an oversight with the tutorial, and I apologise - will update it with corrections.  In the meantime, you can see how these directives should be placed in your script by examining the "ActionTemplate.cs" example script.
  • Thank you Chris,
    solved, now it works.
