Hey there, For my plugin Oraxen, I am working on a mechanic which allows to instantly smelt ores like iron and gold (so when you break them, you directly get an ingot). It is working fine with a pickaxe since if I break an iron ore it gives me an iron ingot, but if I am trying to use a hammer (an item using another mechanic I called bigmining which basically allows you to mine different blocks at the same time) I also get iron ores... Here is the code of my smeltingmechanic: https://github.com/Th0rgal/Oraxen/b...vided/smelting/SmeltingMechanicsListener.java But the problem probably comes from the other mechanics which break blocks that way: Code (Text): private void breakBlock(Player player, Block block) { if (block.isLiquid() || block.getType() == Material.BEDROCK || block.getType() == Material.BARRIER) return; blocksToProcess += 1; // to avoid this method to call itself <- need other way to handle players using the same tool at the same time BlockBreakEvent blockBreakEvent = new BlockBreakEvent(block, player); Bukkit.getPluginManager().callEvent(blockBreakEvent); if (!blockBreakEvent.isCancelled()) block.breakNaturally(); } This allows the hammers to be supported by plugins like worldguard (since they should be allowed to cancel the blockbreak): but in my case this is pretty buggy because what I'm using to cancel the loots (event.setDropItems(false) seems absolutely not working with events called by plugins (not naturally). Did I dod something wrong? Do you have any ideas? Thank you, Thomas!
