Cooler Mod

Version 0.1.6 for How to Fish / BepInEx 5

Cooler Mod adds a reusable low-poly fishing cooler that carries up to 20 fish. It keeps catches organized, frees inventory space, and lets you transport and sell a full fishing haul in one quick interaction. This speeds up long fishing trips and makes them more convenient because you spend less time juggling, dropping, and selling fish individually.

Features

• Stores up to 20 fish in one portable cooler.
• Preserves each fish's species, appearance, cooking state, multipliers, and exact sale value.
• Shows a matching thumbnail, name, multipliers, and price for every stored fish.
• Sells all stored fish together while allowing you to keep and reuse the cooler.
• Lets you take out or drop individual fish whenever you want.
• Supports custom cooler names, saved-world persistence, and multiplayer synchronization.

How to use it

How it works

Deploy the cooler, then look at it and tap E while holding a fish. The fish leaves your hands and enters the first open cooler slot. Tap E with empty hands to open the contents window, where you can inspect, remove, or drop catches and rename the cooler. Hold E to pick the loaded cooler back up. Carry it to a fish vendor and tap E to sell all stored fish while keeping the empty cooler.

Where to purchase it

You can purchase a cooler for $1,000 from any fish-selling money vendor on Islands 2 through 5. Stand within the vendor's normal close interaction range, look directly at the vendor, and press 8 when the Buy Cooler prompt appears. Buying requires one free inventory slot.

The purchase prompt is positioned below the Water Walking Boots prompt so both mods can be used together. When you already hold a cooler, its sell-fish interaction appears first and [8] Buy Another Cooler appears underneath it.

The mod recognizes vendors through the game's Money quest type, the same marker used when an NPC accepts fish and pays the player. This covers the fish buyer on Island 2, the fish buyer on Island 3, both fish buyers on Island 4, and the fish buyer on Island 5. Other quest NPCs, the casino, and unrelated shops do not qualify.

Storage interface

The cooler stores 20 fish. Its interface displays ten slots in each column. Every occupied slot shows a rendered fish thumbnail, fish name, cooking multiplier, score multiplier, and current sale price.

Fish keep their species, displayed name, exact sale value, randomized weight, cooking state, catch/betting multiplier, score multiplier, and skin data while stored. The saved name and exact value drive the matching row thumbnail, combined total, and vendor payout. Contents and custom cooler names persist with the host's world and synchronize to connected players.

Deployment and pickup

The cooler can be deployed on most upward-facing surfaces within eight metres. While deployed it remains anchored, collidable, and protected from cleanup or explosions. Hold E while looking at it to return it to a free inventory slot or to empty hands.

Bulk selling

Hold a loaded cooler, look at a fish-selling vendor, and tap E. The host calculates each stored fish's normal sale value, pays the combined total to the player, empties the contents, and leaves the reusable cooler in the player's hands. Personal wallets from NoSharedMoney are supported when that mod is installed.

You can also throw the cooler into a money vendor's mouth like another item. This sells the cooler itself for $500, adds the value of all fish stored inside, and removes the cooler and its saved contents. Use the E interaction when you want to sell only the fish and keep the cooler.

Multiplayer

Every co-op player should install the same version of Cooler Mod. Purchases, storage changes, deployment, pickup, withdrawals, drops, bulk sales, and saved contents are validated by the host.
