A target block responds when projectiles hit it

A target block in Minecraft is a bullseye-shaped block that emits a redstone signal when an arrow, trident, or other projectile strikes it. The signal strength depends on where the projectile lands — hitting the center ring produces a stronger signal than hitting the outer rings. You can use target blocks to trigger doors, lights, or other redstone contraptions without needing a player to press a button.

Target blocks are made from hay bales and redstone dust, both common materials you can gather or craft early in a survival world. Once placed, they work in any direction — arrows coming from any angle will set up them. This makes them useful for creating automatic systems, puzzle rooms, or practice ranges where you want feedback when you hit your mark.

Key Takeaways

  • Target blocks are crafted from four hay bales arranged in a square with redstone dust in the center.
  • You can obtain hay bales by breaking tall grass with a hoe or by trading with farmers in villages.
  • Target blocks emit redstone signals at power levels 1 through 15 depending on which ring the projectile hits.
  • Arrows, tridents, and other projectiles trigger target blocks, but snowballs and eggs do not.

Gathering hay bales and redstone dust

Hay bales are the main ingredient. You can get them two ways: break tall grass (the green plant that grows on grass blocks) with a hoe and collect nine wheat, then craft those into one hay bale in your crafting table. Or find them in villages — farmers often have hay bales in their work areas, and you can break them and pick them up.

Redstone dust drops from redstone ore when you mine it with an iron pickaxe or better. Redstone ore appears underground, usually below Y-level 16 in most Minecraft versions. You only need one redstone dust for a target block, so a single ore block gives you enough. If you are early in your world and do not have an iron pickaxe yet, focus on gathering hay bales first and come back for redstone once you have iron tools.

Crafting the target block

Open your crafting table and place four hay bales in the four corners of the 3×3 grid — top-left, top-right, bottom-left, and bottom-right. Put one redstone dust in the center square. The remaining four squares stay empty. This arrangement produces one target block.

If you do not see the target block appear in the result box, check that you have placed the items in the correct squares. The corners must have hay bales and the center must have redstone dust. Once the target block appears, click it to move it to your inventory.

Placing and testing your target block

Place the target block anywhere you want to use it — on the ground, on a wall, or even floating in the air if you have a block underneath it. The target block looks like a red and white bullseye from any angle. It does not need to be powered to work; it generates its own signal when hit.

To test it, stand a few blocks away and shoot an arrow at it. You should see a small red spark appear where the arrow hits. If you have a redstone lamp or redstone dust connected to the target block, it will light up or set up. The closer to the center you hit, the stronger the signal — hitting the innermost ring produces power level 15, while hitting the outer ring produces power level 1.

Connecting target blocks to redstone contraptions

Target blocks output redstone power on all sides, so you can run redstone dust, redstone repeaters, or redstone comparators from any face of the block. Place redstone dust next to the target block and it will carry the signal to doors, pistons, lamps, or other redstone devices.

If you want the signal strength to matter — for example, to trigger different actions based on where the arrow hit — use a redstone comparator. The comparator reads the signal strength and can send different outputs to different devices. This is useful for puzzle rooms where hitting different rings unlocks different doors.

What projectiles work and what do not

Arrows from bows and crossbows trigger target blocks reliably. Tridents thrown from a trident also work. Snowballs, eggs, and ender pearls do not set up target blocks, even though they are projectiles. Fireballs from blazes and ghasts will trigger them, as will wither skulls if you are fighting the wither boss.

If you are building a practice range or puzzle, keep in mind that only these specific projectiles will work. This can be useful if you want to create a system that only responds to arrows but ignores other flying objects in your world.

Common uses for target blocks

Target blocks work well in archery ranges where you want visual feedback when you hit. Place several in a line and connect each to a redstone lamp so they light up when struck. You can also use them in puzzle rooms where players must shoot specific targets in order to unlock doors or reveal hidden passages.

In multiplayer servers, target blocks are popular for mini-games and challenges. Some builders use them to create automatic systems — for example, a target block that triggers a dispenser to shoot arrows back at the player, or one that opens a gate when hit from a certain distance. Because the signal strength varies by impact location, you can create more complex logic without needing multiple separate blocks.

Frequently Asked Questions

Can I use a target block without redstone?

The target block itself does not require redstone to exist or be placed, but it only becomes useful when connected to redstone dust or other redstone devices. By itself, it just sits there and emits a signal that nothing receives. You need redstone components to do something with that signal.

Do target blocks work underwater?

Yes. Target blocks function the same way underwater as they do in air. Arrows shot underwater will still trigger them, though arrows lose speed and drop quickly in water, so you need to be closer to hit accurately.

What is the difference between hitting the center and the edge?

Hitting the center ring produces a redstone signal at power level 15, the strongest possible. Hitting rings further from the center produces weaker signals — the outermost ring produces power level 1. You can use a redstone comparator to detect these differences and trigger different outputs.

Can I use target blocks in the Nether or End?

Yes. Target blocks work in all dimensions. They function the same way whether you place them in the Overworld, Nether, or End.

Do mobs trigger target blocks?

No. Only projectiles trigger target blocks. Mobs walking into or touching the block will not set up it. This is why target blocks are safe to use in areas where mobs spawn — they will not accidentally trigger your redstone contraptions.
