Extending Editor with C#

Unity Engine
1

Hello All,

Couple of questions regarding extending the editor using C# rather than Javascript (not a fan of Javascript syntax, and know C# much better than I know Javascript!)

  1. Get an error saying that EditorWindow is not a known type - suspect I haven’t included the appropriate namespace, but I can’t seem to find out what that namespace is - anyone know?

  2. how do I do the @MenuItem (“Window/My Window”) in C#?

Thanks to anyone who is able to help!

  1. You must put the class into the Editor folder and you must import the editor namespace ie using UnityEditor;
  2. @… is JS version of attributes so in C# you write them as [MenuItem(“Window/My Window”)]

You sir are a genius!

Getting another error with this though:

public class NodeGraph : MonoBehaviour {

[MenuItem(“Window/My Window”)]
static void ShowWindow () {
EditorWindow.GetWindow (new NodeGraph());
}

// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {

}

void OnGui()
{
}
}

Assets/Editor/NodeGraph.cs(10,21): error CS1502: The best overloaded method match for `UnityEditor.EditorWindow.GetWindow(System.Type)’ has some invalid arguments

Wrong class there you extend.
you want to extend EditorWindow, not MonoBehaviour

I recommend to give the Script Reference a look to see what functions the EditorWindow class offers and what callbacks it offers

Ooops - needed a type - added GetType()

Doh - yes that isn’t exactly helping!

Thanks for your assistance!

Can’t use new with the editor window - tells me to use scriptableobject.createinstance, but get type doesn’t seem to work with this. Any way I can get the type another way?

Okay - solved - if anyone has the same issue you need to use:

EditorWindow.GetWindow (typeof(YourWindow));
