Solved How to sense whether a player mined a block using silk touch

Hello!
I am creating a simple plugin that gives a player money when mining ores. But there is an issue in which a plyaer using silk touch can just place a block and mine it again to get infinite money. So how do I sense whether a player is using a silk touch pickaxe when mining?

Thanks!

 

@timtower Hmm. Well I'd have to get the player's item in hand first, right? How would I do that? I haven't seen any method of doing that.

 

@Xp10d3 I would suggest to not hook into database everytime a block is broke. It would be better to store data into a class in memory and up every x minuts.

Edit: there'sd a method getItemInMainHand, from player object or playerInventory

 

@caderapee Hmm I haven't thought of that. Thanks

@timtower Lol forgot about that. I'll try that out. Does the Player#getItemInHand allow ItemStack? Cause than I can use #getItemMeta() and than get the enchantment.

 

Not yet. I can't at the moment.

 

Yes, but don't blatantly check the enchantment, this can throw errors. Use ItemStack#hasItemMeta and the ItemMeta#hasEnchantment. Alternatively you can use ItemStack#containsEnchantment(enchantment).

 

@wand555 Alright. Thanks for the help

@timtower @caderapee Seems like player.getItemInHand() is deprecated...?
EDIT: Fixed. player.getInventory().getItemInMainHand(); Going to test it soon.

 

If you want to keep consistency you have to check both hands.

 

@Xp10d3

Not an answer but do you happen to figure out how will you handle iron and gold ores? Because they always drop ores even when not silktouched.

 

Hmm. Could I just check whether the item meta in the player's hand equals silk touch?

And I think it worked. Thanks
@timtower and @caderapee.

 

I mean if they use a pickaxe without a silktouch on it, they will still get the ore and be able to place it and mine it again and again.

 

@Sensevx Oh I see. Hmmm... Well I guess I could just store whether they placed the ore and than in the next event broke it.

Code:

@EventHandler
public void onBlockPlace(BlockPlaceEvent event) {
  Player player = event.getPlayer();
  checkIfTheyPlacedIt();
  if (true) {
    checkIfTheyBreakBlockAgain();
  } else {
    return;
  }
}
