Can't assign a method as a callback in the Editor

I've done this a million times but just not sure why this time it isn't working. I have an OnEvent trigger attached to my character and a separate GameObject with a script called WeaponHandler.cs. This script has a method called IsArmed(). Shown below.

Code (CSharp):

1.  
2. public bool IsArmed()
3. {
4.     return isArmed;
5. }

The WeaponHandler script inherits from MonoBehaviour.

When I attach the GameObject to the event, the WeaponHandler script shows as an option but does not display its "IsArmed()" method.

I have attached a picture below to try and explain better.

 

You're sure your project has no console errors preventing the script from compiling? If no errors, can you post the whole script?

 

Yep, no errors. I can run without any issues. Here's the WHOLE script.

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using Invector.vShooter;
6.  
7. public class WeaponHandler : MonoBehaviour
8. {
9.     public bool IsArmed() {
10.         return transform.childCount > 0;
11.     }
12. }
13.  

 

Okay, here's am odd one. I added a new "Disarm" method and THAT shows up.

Code (CSharp):

1.  
2. public class WeaponHandler : MonoBehaviour
3. {
4.     public Animator animator;
5.  
6.     public bool IsArmed() {
7.         return transform.childCount > 0;
8.     }
9.  
10.     public void Disarm() {
11.         if (IsArmed()) {
12.             animator.SetTrigger("EquipItem");
13.         }
14.     }
15. }
16.  

 

Correct me if I'm wrong, but UnityEvents can only call methods that return void. That's why your Disarm() method shows up, but not your IsArmed() method.

 

Yeah, I feel pretty dumb now. Thanks for the input
