About this project
What does Item Altar add?
Item Altar
Item Altar is a unique and rewarding utility mod that allows you to turn your mob farms and combat encounters into a valuable currency system!
Have you ever had a mob farm and didn't know what to do with so many useless drops? Or maybe you just want to be rewarded for defending your base? With the Item Altar, every entity that dies nearby will grant you Sacrifice Points that you can spend in a custom, easy-to-use shop interface!
Features
- The Altar Block: A magical block that can be crafted using Smooth Stone, Diamond Blocks, Stone Bricks, and Glass.
- Harvest Souls: Any mob that dies within a 7-block radius of the Altar (whether by a player, fall damage, lava, or traps) will automatically grant Sacrifice Points to the Altar.
- Custom Shop GUI: Right-click the Altar to open a custom-designed shop interface. Browse through different categories, use the search bar to find exactly what you need, and buy items instantly using your stored points.
- Data Persistence: Breaking the Altar with a pickaxe will safely store all your hard-earned points inside the item itself. When you place it back down, your points will still be there.
How to start
- Obtain a Diamond Block to unlock the recipe in your recipe book.
- Craft the Item Altar.
- Place it down, ideally near your mob farm or combat arena.
- Watch the points roll in as mobs perish!
- Right-click the Altar and start shopping!
