Hello,

 

I am currently trying to protect a server from xRays, and I want to log every block that is broken by each player so I can see if someone breaks more diamond per stone than he should. I've found a few answers to this question but I didn't managed to make any of these working in 1.12.1...

So I want that every time a player breaks a blocks, a function is called,  with as parameter the player who breaks the block and the type of the block.

Also, this needs to be server side only so a hacker cannot edit the client to bypass this security.

 

Thanks!

I've also tried a few things looking like the first link that I can't find again, none of what I tried threw an exception, it was just doing nothing.

I know it is deprecated, but I'm first trying to make it working before I fix it.

still not working...

I'm in an empty world, and it's the only mod I have enabled...

I tried breaking blocks (that's what I want) (and I also tried going to sleep joining and leaving the server, placing blocks, opening guis...)

Using a breakpoint?

What do you mean by "Using a breakpoint"?

https://help.eclipse.org/neon/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Ftasks%2Ftask-add_line_breakpoints.htm

 

I know what is a breakpoint, but I don't get how it could help me.

is HarvestCheck event better for you ??

What's the difference between HarvestCheck and PlayerInteractEvent?

look at the javadoc for HarvestCheck

 

Okay... I've changed one thing: I registered my event in preInit, init and postInit, and it worked... And now if a register it only one time, it still works...

 

Thanks guys!

Well... actualy this is not total solved... HarvestCheck is only called when using the wrong tool to break a block (example: using a axe to mine diamond ore) and not when using to correct tool. I cannot find the function that is called on every block destroying...

BlockEvent.BreakEvent doesn't give the blocktype of the block destroyed

Yes it does. 

BlockEvent.BreakEvent#state#getBlock()

*I'm so stupid*

Thanks!
