GO.AddComponent just adds an empty Script

Hi there,

i created this Script to ask for a specific Script inside a GameObject. if it doesn´t exist, a Button should appear to create the Script in the GO.

The GetComponent works, the button works - but the AddComponent not…

This is the Script:
using UnityEngine;
using UnityEditor;
using System.Collections;

public class Sys_EventList : EditorWindow 
{
	GUISkin new_skin;
	Vector2 scrollPos;
	Sys_EventRun eventscript;

	// Add menu item named "My Window" to the Window menu
	[MenuItem("RPG System/Event List")]
	public static void ShowWindow()
	{
		//Show existing window instance. If one doesn't exist, make one.
		EditorWindow.GetWindow(typeof(Sys_EventList), false, "EventList");
	}
	
	void OnGUI()
	{
		new_skin = Resources.Load("GUISkin_Event_System") as GUISkin;
		
		GUILayout.Label("Event Liste", EditorStyles.boldLabel);
		EditorGUILayout.HelpBox("Click on a Event Command to open its settings or delete it.", MessageType.Info, true);
		eventscript = null;
		if(Selection.activeGameObject != null){eventscript = Selection.activeGameObject.GetComponent<Sys_EventRun>();}
		if(eventscript == null){
			EditorGUILayout.HelpBox("Add the Sys_EventRun Script to your GameObject to activate the Event System for it!", MessageType.Warning, true);
			if(GUILayout.Button("ADD Sys_EventRun to Object")){
				Selection.activeGameObject.AddComponent<Sys_EventRun>();
			}
		}
	}
}

The only thing that happens is, that an empty Component named “Script” is attached to the GO…
Instead of my Script ._.
What is wrong here?

A few quick checks:

  • Is the script a MonoBehavior?
  • Can you drag it on an object by hand without a problem?
  • Are they in the same package or do you need a “using” statement?
