This resourcepack adds custom items to the game without replacing the original items.

It requires no mods, and use of any datapacks is purely optional (the included datapack allows you to obtain items in survival / without commands, and I strongly recommend the Armor Statues Datapack for infinite posability and placement possibilities). As such, it should be broadly compatible across recent versions of Java minecraft.

The limitation is that these are items and as such, if you place them, they will lose all their NBT data and return to their default appearances.

The sections below list the commands to give yourself each custom item.

To display these items around your world, you have a few options. The first and most obvious is to place them in an item frame. You can then turn the item frame invisible using commands (with Armor Statues installed this is literally just /trigger if_invisble). Another option is to give your item to an armor stand, either to wear (if the item is a carved pumpkin) or to hold in their main hand / off-hand (you'll first need to use commands or the Armor Statues book to get an armor stand with arms). From there, armor statues can also be turned invisible using commands or the Armor Statues book. Finally, any items that replace carved pumpkins can be dispensed onto a mob's head.

Special Note: this item is meant to complement the ghast head dropped via the More Mob Heads and Armor Statues datapacks from Vanilla Tweaks. Explicitly: after placing an armor stand, use the Statues book to give it arms, then set the pose to "Attention." Once that's done, place a ghast head on its head slot and a ghast legs in either hand slot. Set the stand to invisible, and you'll yourself a tiny floating ghast!

Datapack (Optional)

This resourcepack includes an accompanying optional datapack that allows you to obtain these items in survival.

Coffee and Espresso

With the datapack installed in your world, any brewing stand named "Hairo V60" or "Chemex" will brew coffee and espresso instead of potions (they'll all still have their original effects, just with custom names and textures).

"3D printing" custom items

To obtain any of the other custom items, craft a hopper and, using an anvil, name it "Enderman 3 Pro". Directly below where you place this hopper, place a glow item frame, face up.

Then, load any of the base (replaced) items listed above in the first slot, and in the second slot, place a piece of paper with the names listed for each item above (all will be lowercase, with underscores instead of spaces, and ending in ".gcode").

With the datapack running, the base item will then be removed from the hopper, and the custom item will appear on the heated bed, erm, glow item frame.
