A datapack for Minecraft Java Edition which aims to give more gold and iron from smelting. Versions 1.15/1.16/1.17
This is in accordance to the conventions of the Minecraft Datapacks Discord
This uses a hopper right next to any furnace or blast furnace. The hopper needs to have a recipe in it:
Then you need to throw a fire charge into the hopper cavity, not on the rim. Standard button for throwing is "q". Then you'll hear a "whoosh" sound which lets you know it worked. If you destroy the hopper you get these items back, not the fire charge though. If you update to the 1.17 Version, but had the 1.16 Version installed you need to update the blast blast furnaces by throwing a fire charge into the hopper again.
Then you build either: bricks, nether bricks, red nether bricks, stone bricks, end stone bricks, mossy stone bricks, cracked stone bricks, chiseled stone bricks around it in any combination. If you're in the 1.16 Version, additionally cracked nether bricks, chiseled nether bricks, polished blackstone bricks and cracked polished blackstone bricks work as well.
The iron bars are decoration, they're not needed. You can have any block above the furnace, including a hopper, and also any block above the hopper inside the multi-block structure. The multi-block structure can for example be stacked on top of each other:
If the furnace is running it displays the item (nether gold ore) that is being smelted in the hopper together with flames and smoke to simulate the effect that something is being smelted:
When the item changes, the display of the item does too and when the furnace runs out of fuel or there is no item to smelt the display clears to no item being displayed. If there is any block above this hopper the item and the particles won't be displayed.
Iron armour pieces, iron tools, iron sword and iron horse armour, chainmail armour pieces, gold armour pieces, gold tools, gold sword and golden horse armour and most importantly:
iron ore and gold ore. If you use the 1.16 Version it allows nether gold ore too.
The blast blast furnace outputs iron- and gold nuggets into the hopper. From each smelting you get a random amount which loosely respects the amount of ingots that went into crafting the item. From the ores you can get anything from 3 to 9 nuggets.
Click the Download button and save it
Open your minecraft directory, where the savefile for your world is located. Your worldsave contains a folder "datapacks", where the zipfile needs to be copied into. Minecraft will enable new availabe datapacks on a restart of the world. If the world is currently running, you will need to type the command: /reload into chat. If the datapack doesn't show up in the advancement screen I suggest you first try to run the reload command.
To completely remove this datapack from your world, you need to execute a function from chat: /function bbf:uninstall_bbf
This will remove the scoreboards that were added to not clog up the "scoreboard.dat" of your worldsave. Then you can close the world and delete the zip file from your datapacks folder. It might become necessary to close Minecraft completely since a message could pop up saying: "the file is still in use".
This Update changes the marker entity to a marker. The armor stand is now only there for the visuals. Added a manual update path for this change: The player has to throw a fire charge into the hopper again. This will change the armor stand for a marker. No need to destroy the hopper.
