Bullseye - Smart Arrow Detector for Redstone Builds
Vanilla Minecraft's target block has always been a bit of a compromise. It only works from one direction, fires a single, short redstone pulse, and its wooden bullseye aesthetic can clash with a carefully designed build. If you have ever found yourself contorting your redstone layout just to accommodate its limitations, there is a far more elegant solution waiting in the wings. The Bullseye - Smart Arrow Detector for Redstone Builds plugin redefines what a projectile sensor can be, turning nearly any solid surface into a fully customizable, hidden trigger for your contraptions.
Instead of forcing your builds to fit a pre-made block, Bullseye lets the environment itself become the sensor. The core idea is beautifully simple: place a sign on any block, tag it with a keyword, and that block now reacts to incoming arrows. The result is a detection system that is invisible, flexible, and completely under your control. Whether you are crafting a secret trap, a scoring system for a minigame, or a complex piston door, this plugin offers a level of freedom that vanilla mechanics simply cannot match.
Why Bullseye Changes the Game for Redstone Enthusiasts
The primary appeal of Bullseye - Smart Arrow Detector for Redstone Builds lies in its ability to decouple the visual design of a build from its mechanical function. In vanilla, a target block is an obvious, clunky addition. With Bullseye, your sensor can be a brick wall, a bookshelf, or even a chest. The redstone signal is generated on the opposite side of the block, keeping the entire mechanism hidden from view. This opens up a world of possibilities for adventure maps, puzzle rooms, and PvP arenas where subtlety is key.
Furthermore, the plugin offers granular control over the output signal. You are not stuck with a single tick of redstone dust. You can define exactly how long the signal lasts, from a quick pulse to a sustained five-second current. This level of precision allows for more sophisticated contraptions, such as sequentially activated doors or timed dispensers, without the need for complex pulse-lengthening circuits.
Key Features at a Glance
- Universal Compatibility: Works on any block that can hold a sign, including storage containers like chests and functional blocks like furnaces and dispensers.
- Hidden Activation: Place the sign on the back of a block to keep the redstone torch invisible, making the mechanism completely undetectable.
- Customizable Pulse Length: Set the signal duration in ticks directly on the sign, offering precise control over your redstone timing.
- Configurable Block Lists: Use a white or blacklist in the config file to define which blocks can act as sensors.
- In-Game Feedback: Optionally send a custom chat message to the player who fires the arrow, perfect for minigame scoring or puzzle hints.
- Multi-Directional Input: Place multiple signs on a single block to create a sensor that triggers from any side.
Setting Up Your First Arrow Detector
Getting started with Bullseye is refreshingly straightforward and requires no crafting recipes or special items. The process is entirely text-based, making it quick to learn and easy to remember. Here is how to create your first smart sensor.
Step-by-Step Installation Guide
First, you need to obtain a standard sign. Once you have it, follow these simple instructions to transform a mundane block into a high-tech sensor.
- Place the Sign: Equip the sign and right-click on the block you want to use as a sensor. If the block has an inventory, like a chest or dispenser, hold the Shift key while placing to attach the sign correctly.
- Enter the Keyword: Open the sign's edit interface. On the first line, type
[bullseye],[bull], or simply[be]. The plugin is not case-sensitive, so any variation will work. - Set the Duration (Optional): To customize the signal length, add a number after the keyword. For example,
[be 40]will produce a redstone pulse lasting 2 seconds (40 ticks). If you omit this, the default of 30 ticks is used. - Add a Message (Optional): Use the remaining three lines of the sign to type a message that will appear in the chat when the sensor is triggered. You can even use color codes with the ampersand symbol (&) for added flair.
- Confirm Activation: Close the sign interface. If the sign turns blue, the block is now an active sensor. If it turns red, the block is on your config's blacklist and cannot be used.
Once the sign is set, any arrow that hits the block—not just the sign itself—will trigger the hidden redstone torch. This makes aiming easy and ensures the sensor is reliable even in fast-paced situations. If you break the block while the torch is active, you will get the original sign back, preventing any resource duplication.
Advanced Techniques for Hidden Mechanisms
The true power of Bullseye is revealed when you start integrating it into larger builds. The ability to control the pulse length precisely is a game-changer. For instance, a setting of [bullseye 100] provides a 5-second signal, which is perfect for powering a long line of pistons or initiating a multi-stage contraption. This eliminates the need for complex redstone repeaters and comparators, simplifying your build significantly.
For maximum stealth, the strategy is to place the sign on the interior side of a wall. The redstone torch will then appear inside the wall, where it can power dust and repeaters hidden from view. Players on the outside will only see a normal wall, with no indication that it is a functional sensor. This is ideal for creating secret entrances or booby traps that catch players completely off guard.
If you are looking for a hassle-free way to get started, many players find that using a launcher like foxygame.net simplifies the process. It allows you to download and manage mods directly from its interface, automatically selecting compatible versions and saving you from manual file management. This is a great option for those who want to jump straight into building without the technical overhead.
Installation and Compatibility Details
For those wondering how to install, the process is straightforward. The plugin is designed for Bukkit/Spigot servers and requires no client-side modifications. Simply drop the plugin jar file into your server's plugins folder and restart. The plugin supports a wide range of Minecraft versions, including 1.13 through 1.19.1, with partial support for 1.12. It is a server-side solution, so players do not need to install anything on their end.
All major settings are managed in the config.yml file. Here, you can define your block whitelist or blacklist, toggle whether skeleton arrows or dispensers can trigger the sensor, and set a global maximum for the signal duration. The configuration is well-commented and easy to navigate, making it simple to tailor the plugin to your server's specific needs.
Known Quirks and Troubleshooting
While Bullseye is generally stable, there are a couple of minor quirks to be aware of. On Spigot 1.14, you may see a harmless error in the logs regarding a block and tile mismatch, but this does not affect functionality. Older versions had a bug where pouring water on an active torch would cause it to drop as an item while the sign remained, creating a duplication exploit. This has been fixed in current builds. Also, note that if you change the block list in the config, the color of already-placed signs will not update until they are triggered once. This is a caching behavior, not a bug.
Final Verdict: A Must-Have for Builders
In conclusion, Bullseye - Smart Arrow Detector for Redstone Builds is an exceptionally well-crafted tool that fills a significant gap in the vanilla game. It offers a level of flexibility and stealth that is hard to achieve with standard redstone components.

Its simple setup, deep customization, and broad version support make it a universal solution for any server.
