Trying to make button trigger function, but it shows as "missing" even though it is there.

This one is a head-scratcher for me.

I have a button that loads a level.
My level loading script is simple:

Code (CSharp):

1. public class LoadScene : MonoBehaviour {
2.  
3.     public static void LoadLevel (int level) {
4.         SceneManager.LoadScene (level,LoadSceneMode.Single);
5.     }
6.  
7. }

I assign this script to a SceneLoader object, and then I try to activate this through the button. HEre's what happens:


Why is this showing as "Missing" if it is right there and selected?
Of course, it doesn't work.

This was working before when I was calling the same function but without a parameter. Now that I added the parameter, it does this. But if I remove the parameter, it still shows as "Missing".

[edit] I changed the method's name to "LoadALevel" in case it was conflicting with the deprecated method Application.LoadLevel, still the same problem.

 

I believe the issue is that it's static. From this thread:
https://forum.unity.com/threads/unityevent-static-function-call-feature-request.271232/

That still doesn't seem to be possible to hook a UnityEvent to.

 

Aw damnit. This is really annoying, because I wanted to access this method by script too.
I guess I'll have to make an intermediary script that calls the other method. What a pain!!!

Thanks for your help!
