This is a Fabric mod that adds the clay urn to the game, a fragile container that is affected by gravity.
Inspired by old-school RPGs where you had urns/vases/pots around the map which you could break to get their contents, along with Minecraft Dungeons' emerald pots.
Behavior
Container: holds up to one item stack. Right-click or use a hopper to store items;
Mysterious: there is no GUI. To discover what's inside, use either a hopper or brute force!
Affected by gravity: falls if there isn't a supporting block below (like sand);
Mobile: as long as it's falling, you may move it around with slime blocks, water elevators, etc.!
Fragile: if the urn falls from a height of three blocks or more, it will crack. If it's already cracked, then it will break — unless it lands on slime or hay;
Weaponizable: hurts entities on landing (like an anvil);
Craftable: with bricks;
Decorative.
Installation
Make sure you downlaod the Fabric Loader and the Fabric API. Afterwards, just drop the mod into your mods folder.
