TinyBlocks [Development]
by therappha
TinyBlocks gives players a shrink tool that scales ordinary blocks to a fraction of their size, so several pieces can share one normal block space.
What it does
TinyBlocks implements subgrids in the game, so a block placed in a reduced size occupies a fraction of a full block cell. The Craft Minimizer is made from a stick and some iron nuggets, and it is held in the off-hand while a block is placed to shrink it. Development is still in progress, and the author notes that bugs are expected.
Reduced blocks keep their own hitbox and mining speed, and they show the crack overlay and drop items the way full blocks do. Redstone pistons and other interactions pass between neighboring pieces just as they do in the full-size world. TinyBlocks is a NeoForge mod for 1.21.1 only, and it runs on client and server, so the server and every player need it. It is released under the Creative Commons Attribution Non Commercial Share Alike 4.0 license and is not open source, though its source code and issue tracker are public.
Key features
Craft Minimizer
A tool crafted from a stick and iron nuggets, used in the off-hand to shrink a block when it is placed.
Fractional sizes
Blocks can be scaled to a half, a quarter, an eighth or a sixteenth of a normal block and packed several to one block space.
Working block behavior
Reduced blocks retain their own collision shape and breaking time, and mining them produces drops as expected.
Piston interaction
Redstone pistons and other interactions pass between neighboring shrunk pieces as they would in the full-size world.
