f1sch client

A client-side Fabric mod with 25+ utility/hack features. Built for fun, not for cheating on public servers. Inspired by Meteor, Future, and Rusherhack.

What it does

f1sch gives you a configurable ClickGUI (Right Shift) with features organized into categories: Combat, Movement, Visual, Exploits, and Pro. Everything has a keybind, a config slider, and an in-game HUD showing what's active.

Combat

- Low HP Kill / Auto Kill When Low - Extend interaction range from 3 to 50 blocks - Low HP Kill / Auto Kill When Low - Auto-attacks nearest entity in range - Low HP Kill / Auto Kill When Low - Hit all entities in range (Pro version bypasses cooldown) - Low HP Kill / Auto Kill When Low - Crazy knockback on hit, up to 2500 strength - Low HP Kill / Auto Kill When Low - Auto-target low health mobs or panic-attack when you're low

Movement

- Auto Elytra Swap - Creative-style flight in survival with adjustable speed - Auto Elytra Swap - Ground speed multiplier (1-10x) - Auto Elytra Swap - Walk on water and lava - Auto Elytra Swap - No fall damage - Auto Elytra Swap - Auto-place blocks under you while walking - Auto Elytra Swap - Walk up blocks without jumping (1-10 height) - Auto Elytra Swap - Can't walk off edges - Auto Elytra Swap - Always sprinting - Auto Elytra Swap - Autopilot flight to any coordinates with collision avoidance - Auto Elytra Swap - Baritone-lite pathfinding on foot - Auto Elytra Swap - Auto-equip elytra when falling

Visual

- Fullbright - Glowing outlines on entities (color-coded: red=players, orange=hostile, green=passive) + tracer lines + path traces - Fullbright - See ores, chests, spawners, and structures through blocks (broken) - Fullbright - Max gamma, see in the dark

Utility

- Op Self - Browse and give yourself any of 1706 items from a searchable GUI. No OP required (uses datapack triggers) - Op Self - Instant TP to coordinates - Op Self - Auto-eats best food when hungry - Op Self - Keeps totems in your offhand - Op Self - Auto-equip best armor - Op Self - Disconnect at a health threshold - Op Self - Instant respawn on death - Op Self - Silent OP (requires server addon)

Server Addon

The mod works standalone in singleplayer. For multiplayer, there's an optional server addon available in two forms:

- Datapack (full features) - place in the server's `mods/` folder - Datapack (vanilla compatible) - place in `world/datapacks/`, works on vanilla, Paper, Fabric, Aternos, etc.

The datapack lets any player use `/trigger` commands for reach, knockback, speed, fly, nofall, teleport, and item give - no OP needed. Type `/trigger f1sch.help set 1` in chat for a clickable command list.

Important: The server addon has no permission system. Any player with the client mod (or who knows the trigger commands) can use all features. Only install it on servers where you trust all players.

Known Bugs & Rough Edges

things to know

This mod is a passion project, not a polished product. Here's what you should know:

- Config saves on every change only extends client-side targeting. The server still validates at its own range, so you can't actually place blocks at 50 blocks on a vanilla server. Works fully in singleplayer. - Config saves on every change may get you kicked for "Flying is not enabled on this server" without the server addon. In singleplayer, the mod patches the integrated server directly so this doesn't happen. - Config saves on every change Normal mode uses the server addon (reliable). Beta mode spoofs your position client-side and Config saves on every change on most servers. - Config saves on every change sends spoofed on-ground packets. Works on most servers but anti-cheat plugins may catch it. - Config saves on every change only sees entities in loaded chunks. The server addon can extend this range. - Config saves on every change pathfinding is basic. It gets stuck sometimes, tries a 70-degree detour after 40 ticks, and a full reversal after 100 ticks. It's not Baritone. - Config saves on every change collision avoidance only checks 4 blocks ahead. If it gets stuck for 60 ticks, it starts breaking blocks (even ones you might not want broken). - Config saves on every change NoSwing is a placeholder that only hides the animation client-side. A few others are thin wrappers. - Config saves on every change are based on alphabetically sorted item IDs from MC 1.21.11. If Mojang adds items in a future version, codes may shift. - Config saves on every change will likely flag speed, fly, nofall, teleport beta, and fast break. This mod is not designed to bypass anti-cheat. - Config saves on every change globally to suppress output. If you need those gamerules on, you'll have to fight the tick function that re-enforces them every tick. - Config saves on every change Seriously. Anyone can OP themselves, teleport anywhere, or give themselves items if the addon is installed. - Config saves on every change to `config/reachfly.json`. Keybinds persist across mod versions.
