Global variable used to maintain a reference to all event handlers

[YouElz]

Hello everyone,

Could someone clarify the necessity of maintaining a global variable to reference all event handlers?

I've noticed that all sample programs implement this practice. However, as I'm learning scripting, I haven't encountered any situations where it seems necessary, so I've been writing code without it. Am I overlooking something, or are there specific cases where this would be essential?

handlers = []

Hi @YouElz -San.

It is a matter of scope. If you do not use it, the event should not occur.
