This project was created during my study on computer graphics, the C programming language, and the inner works of an game engine over the last year. With its purpose fulfilled, I decided to provide the source code as reference to others who might want to learn from it, as even if it is not exactly architectured like a full blown engine, many of the systems implemented here are present in a way or another in those engines.

Features

• ECS based architecture
• Scene and Prefab editor
• Simple kinematic and dynamic physics
• Lua scripting
• .vox File loading
  • Single object
  • Multiple objects with position and rotation
• Multiple voxel objects rendering in an isometric pixel art style
  • OpenGL renderer
  • Outline, vignette and chromatic aberration effects
  • Point lights and directional light

Building

Dependencies

• SDL, SDL image, SDL ttf
• GLEW
• Lua5.3

Make Commands

• make
  • Build the engine
  • On Windows: modify INCLUDE_PATHS and LIBRARY_PATHS to the location of the libraries in your system
• make clean
  • Remove the ./Build folder
• make tcc
  • Compile and run the engine with the Tiny C Compiler
  • Has some runtime issues when moving objects with the move gizmos
