Game Folder Structure - WIP
This is the guide on how to name things, where to put them, and over-all how we intend to organize the project files.
Considerations
The game project's file structure should achieve several key things:
- Organize multiple repositories into folder structures that can co-exist.
- One directory for the Godot project, a separate directory for the art source files that are created outside of the engine.
- These directories will each be a Git repository and should conform to the hyphenated naming convention.
- These names should make sense in and out of context, the top-level folder name should make sense when viewed as a tab in a Git GUI e.g:
- example-game
- example-art-source
- example-audio-source
- Splitting the repositories avoids having to sync large amounts of irrelevant content for your role on the project:
- Programmers / Dev Ops / Build Bots should only need to sync the example-game repository.
- Artists / Animators can sync example-art-source along side the example-game repository.
- Musicians / Foley Artists can sync example-audio-source along side the example-game repository.
- The folder structures should work without using Git sub-modules, since sub-modules add a lot of complexity and confusion without really adding value.
- The folder structures in these directories should mimic each other 1:1
- Tools and pipelines should be able to export / import content by simply swapping the root, e.g:
- example-art-source/art_assets/characters/main_character/main_character_diffuse.png
- |--->example-game/art_assets/characters/main_character/main_character_diffuse.png
- Ship-able game content should be the only thing going into the Godot project resource folder in the game repo.
- Art source content from tools like Blender, Gimp, Krita, etc... should be kept in the art-source repo.
- Music production files for a DAW should be kept in the audio-source repo.
Naming Conventions
- The repositories should use lowercase-hyphenated-case
- Files and folders should use snake_case unless otherwise required by third-party tools or conventions for the specific file e.g. README.md
- No spaces in file names.
Compromises
No folder structure is perfect, but this structure should lead to the fewest problems. Here is a list of known compromises we've decided to accept:
Top level folder names repeat the game's name even though they are already inside of a top-level folder named after the game:
- example
- example-game
- example-art-source
- example-audio-source
While this introduces redundancy, folders don't cost anything, so this is okay.
Some intermediate sub-folders are empty and seem to be useless, but they keep the hierarchies between directories in perfect sync. For instance, example-art-source may never end up with content directly inside of it, most if not all content will be inside of its first sub-folder art_assets i.e. example-art-source/art_assets/ This is on purpose, since it ensures the game content is at the same hierarchical indentation level to the source content, making pipelines and paths extremely easy to work with; just swap the root and you're done!
You aught have a directory on your computer for "BUGJam" projects. You can place this anywhere on your computer with a few considerations:
- Do not sync this directory with OneDrive, iCloud, Google Drive, or any other backup tool, this will break the Git repositories inside the folder since these services interfere with Git.
- Don't nest the folder too deep so you avoid file name length issues:
- Good (Windows style path):
C:\Users\xgreer\Projects\BUGJam - Good (MacOS / Linux):
/home/xgreer/Projects/BUGJam - Bad:
/home/xgreer/Projects/Extra Projects/Seattle Blender User Group/Game Projects/BUGJam
- Good (Windows style path):
Within the BUGJam directory there will be folders for each BUGJam project. For a project called 'Genesis' we will have a project folder called 'genesis' that serves as the root for all content necessary to develop the game.
