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.
