[1.12.1][Solved] Call a function every time a block is broken

[Neirpyc]

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.

[Neirpyc]

still not working...

[Neirpyc]

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

[Neirpyc]

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?

[Neirpyc]

What do you mean by "Using a breakpoint"?

[Neirpyc]

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

[loordgek]

is HarvestCheck event better for you ??

[Neirpyc]

What's the difference between HarvestCheck and PlayerInteractEvent?

[loordgek]

look at the javadoc for HarvestCheck

 

[Neirpyc]

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!

[Neirpyc]

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!
