How to make a simple addon that executes a script on every mission

[unloco 13]

Hello,

I need to make an addon that will simply execute a script on every loaded SP mission

I couldn't execute my script on downloaded missions so I thought I make an addon for this

Is there a sample addon that I can follow and introduce my script

Please help

Edit: I found this sample, it's very helpful

Thank you
