Experimentation Table - (Works 26.1.2 and 26.2)

An independent Auto Experiment mod for Minecraft 26.2 / Fabric (client-side only) It solves all three Experimentation Table games automatically — Chronomatron, Ultrasequencer and Superpairs — with no GUI of its own. Everything is configured in-game via /experiment commands.

Features

• Chronomatron — records the revealed (foil) note each round, then replays the whole sequence in order.
• Ultrasequencer — reads the revealed notes (dyes / lapis / bone meal), orders them by their count label, and replays them in order.
• Superpairs — tracks revealed pairs (by item + name) and clicks both slots of each match — can be disabled with /experiment superpairs off while Chronomatron / Ultrasequencer keep running.
• Human-like Timing — automated Gaussian intervals, 2D cursor distance scaling, and reaction delays.
• No GUI — the feature is toggled and configured entirely through /experiment commands; settings persist to config/lyn1-experiment.json.
• Game identification is purely client-side: the open screen title selects the solver, and clicks use standard PICKUP (Left Click) container interactions.

Commands

Command	Effect
/experiment	Show current status, superpairs setting, baseline ping, and current ping
/experiment on / off	Enable / disable the solver
/experiment superpairs on / off	Enable / disable Superpairs auto-matching
/experiment ping	Check current detected server ping and baseline delay
/experiment ping <ms>	Set baseline ping delay buffer (0–1000 ms, default 0)

Confirmation example (green in chat):

[Lyn1-Experiment] Baseline ping delay set to 150 ms        (in-game, shown in green)

Configuration

Settings are saved to config/lyn1-experiment.json:

{
  "basePing": 0,
  "enabled": true,
  "superpairs": true
}

Field	Type	Range	Default	Description
basePing	integer	0–1000	0	Minimum baseline ping buffer in milliseconds
enabled	boolean	—	true	Solver on/off
superpairs	boolean	—	true	Superpairs auto-matching on/off

Usage

1. Install Fabric Loader 0.19.3+ for Minecraft 26.1.2 or 26.2 and drop lyn1-experiment-0.1.0.jar plus Fabric API into your mods/ folder.
2. Launch the game, join Hypixel SkyBlock and place your Experimentation Table on your island (or use the Community Center one).
3. Open the table — the mod starts solving automatically (it is enabled by default; disable with /experiment off if needed).

Building from source

Requirements: JDK 25 and an internet connection.

git clone <repo-url>
cd lyn1-experiment
./gradlew build

The built jar is at build/libs/lyn1-experiment-0.1.0.jar.

How it works

1. Every client tick, if the open screen is a ContainerScreen, its title is read and mapped to a game mode (Chronomatron / Ultrasequencer / Superpairs (…); … Stats titles are ignored.
2. A snapshot of all container slots (item id, count, foil, name) feeds the solver.
3. The solver decides the next click:
   • Chronomatron: slot 49 control; during the demonstration phase (non-clock, e.g. glowstone), notes light up with foil/glint and are recorded into sequence memory; when the control switches to clock, the full sequence is clicked back in order.
   • Ultrasequencer: slot 49 control; glowstone = reveal: notes in slots 9–44 are sorted by their count label (count − 1 = replay index); clock = replay: click the mapped slots in order.
   • Superpairs: revealed items (not glass / clock / glowstone / black dye, with a name) are paired by item+name; both slots of each pair are clicked.
4. Clicks are spaced by dynamic humanized delays and sent via gameMode.handleContainerInput(..., ContainerInput.PICKUP, ...).

Human-like Timing & Click Randomization

The mod features a behavioral simulation engine to avoid metronome-like inputs:

• Standard Input Packets: Clicks use standard ContainerInput.PICKUP Left Click packets (button = 0), matching normal human player interactions.
• Glowstone $\rightarrow$ Clock Reaction Delay: When the game transitions from the reveal phase (glowstone) to the input phase (clock), the mod simulates human perception time using a Gaussian curve ($\mu = 330\text{ ms}, \sigma = 40\text{ ms}$, clamped to $[250, 480]\text{ ms}$).
• Spatial Distance Scaling (Fitts's Law): Calculates the 2D Euclidean distance between successive slots on the $9 \times 6$ inventory grid, adding $16\text{–}24\text{ ms}$ per grid unit so distant slots take naturally longer to reach than adjacent ones.
• Gaussian Jitter: Every click interval incorporates standard normal variance ($\mathcal{N}(0, 25^2)\text{ ms}$, clamped to $[-45, +65]\text{ ms}$) on top of the configured base delay.
• Contextual Hesitation:
  • Superpairs: Introduces a $160\text{–}290\text{ ms}$ visual search pause when locating a new matching pair, followed by rapid pair confirmation.
  • Sequence Recall: Adds a 10% chance of a micro-hesitation ($45\text{–}95\text{ ms}$) during extended sequence playback.
• Network Ping Compensation: Automatically samples real-time server latency from packet headers (PlayerInfo.getLatency()) and adds max(configuredBaseline, detectedPing) to click intervals, guaranteeing the server has acknowledged and rendered prior slot updates before issuing subsequent clicks on high-ping or laggy connections.
• Screen Open Orientation: Pauses $300\text{–}500\text{ ms}$ upon opening any table GUI before initiating inputs.
