What is JulGame?
JulGame is an open-source game engine meant for creating 2D games (and 3d games… eventually) using the Julia programming language. JulGame uses SDL2, and CImGui for the editor. The plan for 3d will be to use OpenGL.
Why did I make it?
Because I find Julia interesting, and I’ve always wanted to create a game engine. I would like to see a game dev scene around it as there isn’t much of one now. I am not a Julia programmer (nor an experienced game engine creator), so I am sure there is a lot I am doing wrong. If you see anything that I can fix, please just let me know with a discussion or an issue.
Why JulGame?
I thought that JulGame would be a great play on Pygame. I also think it just rolls off the tongue. Also, I recently found out that “Jul” is the etymological root of “jolly”, so it makes for a great pun :)
How to get started?
] add JulGame for the latest in the package manager
] add https://github.com/Kyjor/JulGame.jl for main - RECOMMENDED as any bug fixes will immediately go here.
] add https://github.com/Kyjor/JulGame.jl#develop for develop
Either download the latest release of the editor, or run it using the Julia REPL:
using JulGame
JulGame.Editor.run()
How do you use it?
Once you have the editor open, download the example, unzip it, and then enter the path to the root of the project along with the scene name (scene.json) in the editor under the Project Location window. Poke and prod around to figure things out until we have some real docs :)
🔴Warning🔴 Save often! The editor will crash with no remorse! Any big changes you make, save immediately.
How do you run your scene?
Navigate to your project, and cd to the directory with Entry.jl, and run julia Entry.jl, and it should start!
What needs to be done?
General
- Documentation
- Video tutorial
2D Engine
General
- Entities can be children of other entities, with editor support
- Tests
- Prefabs (like Unity Engine)
- Engine time system
Visuals
- Simple Rendering
- Basic particle system
Physics
- Better physics in general
- More efficient collision handling
- Raycasting
Animation
- More options than just item crop
Input
- Controller support
Scene Management
- Multiple scene support
Editor Features
- Sprite cropping tool for animations
- Hot reloading with Revise.jl if possible
- Profiling
- Debug console
- A better way to display the scene. There is no SDL backend support for the port of CImGui, so we are stuck rendering two separate windows at the moment
- Scene Grid
- API
- Tile map editor
- Multi-select entities
- Right click context menus
3D Engine
- 3D rendering
- A robust list of 3D engine features…
Build Support
- Windows
- Mac
- Linux - May have to use LDTK
- Web ???
- Mobile ???
- Console ???
Inspirations/Credits
This is a list of references that I used in order to get JulGame where it is, along with people who inspired the creation of this (who you should definitely check out!)
- Solar Lune, who is creating a 3d renderer. This format for the readme is also referencing theirs.
- Coder Gopher, who has tutorials that helped me get started with SDL.
- Lazy foo, who has tutorials that brought me the rest of the way with SDL.
- and so many others who I will note some of in the future :)
Games Made With JulGame
Here I will be keeping a list for the first games created with JulGame :)
