Thanks for that. It was very helpful. Can this event fire when other players break a block, just curious.

That's annoying, any way to log when I break/place a block on the client without putting stuff on the server?

Thanks for explaining this. This is my third attempt to make an minecraft mod, so I tend to not be able to find the best way to do things. Which event can I listen for on the client side, so I know when some player breaks/places a block that I can see?

Not sure by what you mean by that, could you elaborate a bit more. The mod is meant to be run on client side only. I only found this by accident when I was looking for where somebody was obtaining their mc variable from. If this is not the right way to do it, please tell me the correct way. I think the only thing I'm using it for is to get the current player's username.

I'd like to join. Pretty much all I do in my other server I play in is afk. My discord is smashmaster#0045. Also is there claimming in the server or is it pretty much everyone trusts each other. I might not be active until after next saturday since I need to afk for rockets this week.

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.

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?
