GO.AddComponent just adds an empty Script

Question

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?

yes it's a MonoBehavior (language C#) i tried with a complete new created script - even this is not added.

yes i can drag them to an object without problems (but the button way is more userfriendly - especially in greater projects)

the script is in the same package.

What about adding a different script with that code? Does that work? Also, what does your Sys_EventRun script look like? Does it use any weird stuff in it?

The Sys_EventRun is a Struct interpreter. My whole system is something like the rpg-maker Event System (but with less commands).

It holds a public list struct wich stores event informations (like command strings, framecounts, animation names..etc)

It runs through the list, and starts one action after another (when the previous action is done).

so - the script holds a list, and a function with many if consitions to ask for the list contents. nothing weird.

i tried to add a newly created script (create -> script c#) - not working.

GO.AddComponent just adds an empty Script
