Firefly Game Engine

Currently in development
Experimental beta

Firefly is a cross-platform game engine built with C++ using GLFW.

Development Roadmap

Setup

• Setup C++ project
• Create custom bin/ path for intermediate files
• Create dynamic linking with GLFW library
• Integrate static GLEW library for future support for GLFW
• Add .gitignore to remove OS-specific binaries

Window

• Add window.h class definitions
• Add window.cpp implementation
• Add firefly::graphics::Window test in main.cpp
• Add key press and mouse press events
• Add dynamic mouse and key location fetching
• Link key, mouse, and cursor position callbacks to GLFW superwindow
• Add debugging mechanism to detect OpenGL errors
• Create unit testing for firefly::graphics::Window

GLEW

• Init glew inside header.cpp to allow future library utils

Math

• Create vec2, vec3 and vec4 objects with basic operations
• Create math.h header for math library
• Develop mat4.h for 4x4 matrices and define common operations
• Add union data management to extract matrix column easily
• Add common math functions in math_func.h
• Add unit testing for math library
• Add epsilon floating point comparison for equality or inequality operations

Shaders

• Add shader.h class definition and implementation
• Create basic test frags and verts for gradient
• Test visual matrix rotation and transformation
• Create unit testing environment for firefly::graphics::Shader

Buffers

• Create buffer.h, arraybuffer.h and vertexarray.h for rendering engine
• Test with gradient implementation

Renderers

• Create Renderable.h superclass for future renderable type prototype
• Create simple 2D renderer class
• Develop faster, batch renderer in BatchRenderer2D
• Benchmark BatchRenderer2D and Simple2DRenderer with 57000 untextured sprites

Benchmarking

• Create timer class to determine FPS

Layers

• Create base class layer.h
• Create tile layer tilelayer.h and test in main.cpp
