This is my first forum post so I aplogize if I do anything wrong or assume this is markdown somewhere since I'm used to it.
I'm building a mod to detect block changes, when people start raids, ...etc to prevent griefing while you afk.
Here is my code

This works when I play in a singleplayer world however when I build it, and copy it into a standard forge minecraft 1.15.2 client and run it none of the events are triggered. The log file is created but is empty. I know it's probaly a bad idea to flush the file when the inventory opens but that's just temporary testing.
Second question: Since I'm not able to test yet but does my code detect other players breaking/placing blocks. If so how can I make it detect those events?
