About this Mod
Adds a brand-new redstone block: the Block Placer, designed as the "constructive" counterpart to the Dispenser. Instead of ejecting items, it places the block from its internal inventory directly in front of it. Ideal for automating construction, farms, or technical contraptions.
How it works in-game:
| Action | Behavior |
|---|---|
| Crafting | 3×3 recipe: 7 cobblestones surrounding a block of redstone, with 1 redstone dust in the bottom-center slot. |
| Placement | Automatically faces the player when placed, just like a dispenser. |
| Redstone | Reacts to redstone pulses: each signal tries to place 1 block from the first non-empty slot. |
| Targeting | Places the block only if the target space is empty and the block can survive there (same logic as the player). Otherwise, behaves like a dropper and ejects the item. |
| Inventory | Contains 9 internal slots. Compatible with hoppers, minecart hoppers, and other modded item systems. |
| Breaking | Breakable with a pickaxe (any tier). Same hardness/resistance as a dispenser. Always drops itself and its contents. |
| Sound & particles | Uses the same sound and visual effects as a vanilla dispenser for seamless integration. |
This is my first mod, if you find any bug, report it to me :)

Server lagging with Block Placer – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Block Placer consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
