game3

game3 is a multiplayer top-down 2D game with inspiration from Minecraft and Factorio. It's written in C++ and uses a custom OpenGL-based engine and UI framework. Check out the wiki or download the latest Windows build! If you find bugs, please report them on GitHub.

Machines

Game3 has a variety of machines that players can build and use. They can produce and process resources, such as items, fluids and energy. Examples include fluid pumps, autocrafters and geothermal generators. Machines can be connected together with fluid pipes, item pipes and energy wires.

History

The initial commit to the repository was on May 20, 2022. The initial plan was to use Godot as the game engine, but this idea was quickly scrapped when I realized that creating games in Godot purely in C++ without any GDScript is more pain than it's worth. I switched to Cairo for graphics and gtkmm4 for the GUI, but Cairo offered limited primitives and my test program showed glitches with texture rendering. At that point I switched to the current approach, which is to use OpenGL directly. This offers opportunities for better performance and finer control. I still used gtkmm4 for the GUI outside the canvas where the game world was rendered, but because this posed issues when I tried to port the game to Windows, I eventually switched to GLFW and a completely custom UI framework inside OpenGL.
