Chef’s CookBook

CookBook is a quality-of-life mod for Risk of Rain 2 that provides a structured, searchable, and expandable view of craftable items and their possible crafting paths.

Instead of mentally tracking multi-step recipes or juggling Wiki tabs, CookBook presents crafting information in-game with a clean, scalable UI designed for large inventories and complex recipe graphs.

Features

Frontend

• Lists all currently craftable results based on your inventory, grouped by result type, rarity, and quantity
• Live filtering via a search bar
• Each recipe row can be expanded to reveal all valid crafting paths
• Highly configurable via ROO settings integration for your performance needs
• Paths are displayed hierarchically, showing exact ingredient requirements
• Accordion-style UI keeps only one recipe expanded at a time to reduce clutter
• Rows grow and collapse naturally with content
• Support for repeatedly executing a specific craft chain N times in a single automated sequence
• Automatically calculates and displays the "Max Affordable" repetitions for any selected path, physically clamping user input to current inventory limits
• Event system to prompt other mod users if someone is requesting their assistance in a recipe!

Backend

• Robust against other mods
• Highly encapsulated, doesn't touch any external logic
• Automated sequences include logic to orient active equipment slots and sets
• Backend cleanly separates data, logic, and UI for extensibility
• Optimization layer that kills redundant crafting chains early if a more efficient path (based on item weighting) is already discovered for the same result
• Recipes are culled early in the compute phase using IsCausallyLinked to prevent the generation of circular or impossible crafting paths
• Hooks specifically monitor permanent item stacks and equipment sets, ignoring temporary buffs and activations
• Affordability logic accounts for the entire team's potential by tracking scrapable drones and allied inventory trade limits

Controls

• Configure various keybinds and crafting features in the Mod's settings menu
• Click a recipe row to expand or collapse its available crafting paths
• The search bar filters results in real time
• Expand a recipe row, select the path you want, then select craft
  • The Objectives panel will be updated to visualize the status of the craft chain
  • Hold left alt to cancel an in progress craft

Technical Overview

• Extensive use of templating to maximize rendering performance
• No prefabs baked into the scene
• Minimal layout group usage for predictable behavior

UI Architecture

• Dynamic layout groups
• Content size fitting for automatic row expansion
• Explicit hierarchy control for stable rendering
• UI logic structured to avoid per-frame allocations (no performance dips)

Future updates may introduce pooling for recipe rows if necessary.

Development Status

This mod is under active development!

Planned features include:

• Visual polish and UI refinements for UI frontend (this is my first mod, and Unity UI is painful)
• In-Progress run recipe tracking
  • An in-progress view to view all recipes and their completion status, accessed by holding tab (inspectable so that the game can be paused while reading)

Compatibility

• Does not modify gameplay logic
• Does not interact with networking (no host required!)
• Entirely client-sided, other players are NOT required to have the mod installed.
• Should be compatible with most content mods that introduce new items or recipes
