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


Recommended Posts

Posted (edited)

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!

http://www.minecraftforge.net/forum/topic/7604-handle-playerinteractevent-problem/ -> doing nothing

http://www.minecraftforum.net/forums/minecraft-discussion/redstone-discussion-and/commands-command-blocks-and/2475128-detect-when-a-player-breaks-a-certain-block -> not what I want

 

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.

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...

    • Version 1.19 - Forge 41.0.63 I want to create a wolf entity that I can ride, so far it seems to be working, but the problem is that when I get on the wolf, I can’t control it. I then discovered that the issue is that the server doesn’t detect that I’m riding the wolf, so I’m struggling with synchronization. However, it seems to not be working properly. As I understand it, the server receives the packet but doesn’t register it correctly. I’m a bit new to Java, and I’ll try to provide all the relevant code and prints *The comments and prints are translated by chatgpt since they were originally in Spanish* Thank you very much in advance No player is mounted, or the passenger is not a player.
