Blocky13

A Minecraft Fabric mod that adds decorative and functional block variants for Minecraft 26.1+.

Features

Blocky13 expands the building possibilities in Minecraft by creating a comprehensive set of variants for base materials. For each of 15 different base blocks (dirt, iron block, coal block, copper block, gold block, redstone block, emerald block, lapis block, diamond block, netherite block, raw iron block, raw copper block, raw gold block, quartz block, and amethyst block), the mod generates:

Slabs — Half-height blocks for detail work
Stairs — Diagonal blocks for elevation changes
Fences — Perimeter blocks with no collision
Fence Gates — Openable fence segments
Doors — Full-size entryways
Trapdoors — Horizontal access blocks
Pressure Plates — Redstone input sensors
Buttons — Redstone input triggers
Chains — Hanging connectors
Bars — Decorative barriers

Redstone-Powered Variants

All blocks made from redstone block material have special powered variants that emit a constant redstone signal (strength 15), making them useful for redstone contraptions and automation. These blocks appear in both the Building Blocks and Redstone Blocks creative tabs.
