VisibleArrowTrap

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

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

| Setting | Default | Range / Options | Description |

|---|---|---|---|

| Color | Red | Original, Red, Orange, Yellow, Green, Blue, Violet | Warning line color preset. |

| Brightness | 1 | 0.2 – 3 | Color intensity multiplier. |

| Width | 0.045 | 0.01 – 0.3 | Line thickness, in world units. |

⚠️ 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.
