About this mod Author’s original text

CoinBeams

Find the loot worth carrying, without hunting pixel by pixel.

Grain Rot marks valuable items with a small sparkle. It is easy to miss in a dark room, and telling a Rare from an Epic usually meant walking up to each one and inspecting it. CoinBeams makes the whole system readable at a glance.

What it does

Loot beams on coins. Every gold coin and artifact coin gets a soft, see-through pillar of light rising from it — gold beams on gold, purple on artifact. The beam always points straight up, however the coin lands, tumbles, or flies.

A rarity glow under valuables. Furniture, paintings, plants, lamps and treasures each get a small coloured light at their base, in the colour of their tier. A light has no shape and no up-vector, so it sits correctly on a hanging picture just as well as on a floor prop. It never casts shadows and the count is capped per level.

Brighter sparkles. The game's own rarity sparkle is amplified rather than replaced — bigger and faster, still scattered across the item's own surface, still in the game's own colours.

Rarity colours

| Tier | Colour |

|---|---|

| Common | White |

| Rare | Blue |

| Excellent | Pale cyan-blue |

| Epic | Purple |

All four tiers are marked by default.

Multiplayer and safety

Purely client-side visuals. Nothing is replicated, no gameplay value is changed, and friends do not need the mod installed. Lights never cast shadows, particle work is capped and spread across frames, and all cosmetic work waits for the level to finish streaming before it runs.

Configuration

Open Scripts/main.lua and edit the CFG block at the top.

| Setting | What it does |

|---|---|

| ITEM_LIGHT | Master switch for the rarity glow |

| ITEM_LIGHT_INTENSITY | Glow brightness in candelas |

| ITEM_LIGHT_RADIUS | How far the glow reaches, in cm |

| MAX_ITEM_LIGHTS | Ceiling on lights per level |

| OUTLINE_MIN_QUALITY | Lowest tier that gets marked — 0 Common, 1 Rare, 2 Epic |

| OUTLINE_MAX_QUALITY | Highest tier that counts as loot — 3 includes Excellent |

| OUTLINE_COMMON / OUTLINE_RARE / OUTLINE_EXCELLENT / OUTLINE_EPIC | Tier colours |

| SPARKLE_SPEED | Twinkle rate of the item sparkles |

| SPARKLE_SIZE_MULT | Sparkle size |

| ITEM_BEAMS | Optional upright beam on valuables (off — it misaligns on wall-mounted items) |

| LAYER_COUNT, BASE_H, TIP_H | Coin beam shape and height |

Install

Use a mod manager — it handles the dependency and the file layout for you.

Version catalog

1.3.1

  • Lamp-type valuables now get their glow. Floor lights, lamps and anything else that emits light were skipped entirely — the check that prevents double-lighting asked whether the item already owned a light component, which is true of every lamp by definition. It now tracks only the lights this mod adds.
  • Items no longer need to be approached or nudged first. The game puts particle systems to sleep when you are not near them, and sleeping sparkles were being ignored, so an item stayed dark until you walked up to it or picked it up. A room now lights up as you enter it.
  • Added a fallback for items that refuse a light on the first attempt, and raised the per-level light ceiling from 28 to 64 now that far more valuables are found.
  • New icon.

1.3.0

  • Excellent tier now supported. The game has a fourth rarity above Epic that inspects as "Excellent" and carries its own pale-blue sparkle. Every earlier version discarded those items outright, so they never got a glow. They are now marked in their own colour.
  • Furniture is marked properly. Chairs, tables, paintings, floor lamps and plant pots were being skipped because the mod only looked for treasure-class objects. It now treats anything the game attaches its rarity sparkle to as loot, which covers every sellable prop type.
  • The sparkle boost actually applies. A component test was checking a property that does not exist, so the pass that enlarges and speeds up the game's own sparkles had never once run. Sparkles are now noticeably livelier.
  • Glow retuned much softer aft

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide.
