VisibleArrowTrap

A BepInEx mod for PEAK that makes the Citadel arrow trap's warning line actually visible.

Overview

In the Citadel biome, arrow-shooting traps project a "laser pointer" style warning line that fires an arrow when a scout (or an object like a dropped backpack) crosses it. The stock line is a faint, soft-edged line that easily blends into the environment, so it's easy to miss until you're already hit.

VisibleArrowTrap replaces it with a solid, crisp, configurable-colored beam, so you can actually see it coming.

• Client-side visual change only — no gameplay logic is touched, so it's safe to use in multiplayer even if other players don't have it installed.
• Choose from several color presets, or restore the game's original look on demand.
• Adjust brightness and thickness to taste.

Requirements

• PEAK (Steam)
• BepInEx 5.4.x (Mono)
• PEAKLib.ModConfig — optional, but recommended. Adds an in-game settings menu so you don't have to edit the .cfg file by hand.

Installation

1. Install BepInEx for PEAK, if you haven't already.
2. (Recommended) Install PEAKLib.ModConfig for an in-game settings UI.
3. Drop VisibleArrowTrap.dll into BepInEx/plugins/ (a subfolder is fine).
4. Launch the game.

Configuration

Settings are stored in BepInEx/config/VisibleArrowTrap.cfg, and can also be changed in-game from the MOD SETTINGS menu if PEAKLib.ModConfig is installed. Changes apply immediately to any traps already in the level.

⚠️ Color = Original behaves differently

Selecting Original restores the trap's warning line to the game's own vanilla appearance — including its own width — and in this mode, Brightness and Width are ignored. This is intentional: the game's own line material doesn't respond to color/brightness the way this mod's custom beam does, so Original always renders exactly as unmodified PEAK does.

For every other Color option, Brightness and Width apply normally.

Compatibility

• Only patches ArrowShooter.Awake. Doesn't touch any other trap, enemy, or system.
• Purely cosmetic — arrow-firing logic and networking are untouched.
