  • Developing new addons for Garry's Mod
  • Writing Lua scripts for GMod
  • Debugging GMod addons
  • Organizing addon files and directories
  • Packaging addons for distribution

Addon Development Workflow

When creating a GMod addon, follow these steps:

  1. Conceptualization
    • Define the addon’s purpose and features.
    • Identify target audience and use cases.
  2. Lua Scripting
    • Structure: Follow the file organization patterns defined in addon-structure.
    • Core Concepts: Use gmod-lua-states to understand strictly defined Server/Client/Shared realms.
    • Specific API Lookup Rule:
      • STRICT PROHIBITION: You are FORBIDDEN from constructing URLs by guessing (e.g., Do NOT try wiki.facepunch.com/gmod/hook). Most guessed URLs are 404 errors.
      • Action Sequence:
        1. Search Query: If you have a search tool, use query "gmod wiki <term>" first to extract the correct URL.
        2. Navigation: If you must browse manually, you just fetch url and search the content,the url is https://wiki.facepunch.com/gmod and the search term is the API or concept you want to find. Do NOT guess URLs.
        3. Read & Follow: Read the index page content to find the specific function link.
  3. Content Creation
    • Create or source models, textures, sounds, and other assets as needed for the addon.
    • Ensure all content is properly licensed for use in your addon.
    • Ensure content is optimized for performance and compatibility.
  4. Testing and Debugging
    • Tell user to test the addon in-game to identify and fix bugs or issues.
    • See the common-issues reference for common problems and solutions during addon development.
