Boo Events

Questions & Answers
1

I am trying to create a singleton class for handling events, which could then be registered and fired by other classes.
Here is my code so far:

import UnityEngine

class Events (MonoBehaviour):
	static public Handler as Events
	public GameOver as callable()
	
	def Awake ():
		if not Handler:
			Handler = self
			
	def FireGameOver ():
		GameOver()

However, trying to add a method to the event fails with error “Object reference not set to an instance of an object”. Here is my testing class:
import UnityEngine

class SomeCollider (MonoBehaviour): 

	def OnCollisionEnter (collision as Collision):
		if collision.gameObject.tag == 'MakeTest':
			Events.Handler.GameOver += Test
			Events.Handler.FireGameOver()
			
	def Test ():
		print('Test')
		
	def Test2 ():
		print('Test2')

Also, is there any way to avoid the need for the FireGameOver method? Or any easier method to implement this approach?

After much trial and error, I found the solution myself:

(Events.boo)

class Events:
	static public event GameOver as callable()
	static public def FireGameOver():
		GameOver()

(SomeCollider.boo)

import UnityEngine

class SomeCollider (MonoBehaviour): 
	def OnCollisionEnter (collision as Collision):
            Events.GameOver += Test
		Events.FireGameOver()

    def Test ():
        print('Test')

I could not, however, find a solution that would avoid the need to define a function for each event, as they appear to not be callable outside of the class methods.
