Colubris Game Engine

Colubris is a simple 2D game engine written from scratch in OpenGL, with the help of FreeType library, which supports, among other features:

• a hierarchy tree of objects,
• a component-based system for custom object behaviour,
• 2D rendering of objects composed of polygons and circles,
• text rendering,
• collision detection of polygon colliders,
• user input detection (keyboard),
• grouping and ordering objects in layers.

Libraries used:

• GLFW,
• GLAD,
• GLM,
• FreeType 2.

Setup

To setup the working environment, clone the repository, install the freetype2 library, then configure and build the project using CMake.
