Hickory

Hickory is a game engine for Haskell. The pieces (vulkan renderer, input systems, resource loading, game state management) are fairly modular, allowing some pieces to be used without committing to others.

Core library: 'Hickory'

• Vulkan Graphics
• 3D Model Loading / Animation
• Camera Projection/Unprojection
• Text Rendering
• Raw Input (Mouse clicks / touches and key pressses)
• Misc. Math Utilities

Functional Reactive Paradigm: 'Hickory-FRP'

• Built on the 'Reactive Banana' FRP library
• Game loop
• Separate rendering and physics time steps
• Game state recording and time-travel
• High level UI widget abstraction

GLFW Backend: 'Hickory-GLFW'

• Easy initialization of a Vulkan context and input handling for GLFW (a cross platform desktop library)

iOS Backend: 'Hickory-iOS'

• Easy initialization of a Vulkan context and input handling for iOS
• Some additional fiddly work needed to get a working binary, but overall this is a relatively painless way to get into iOS development

Getting started

The Examples/ directory has a simple action game example.

$ stack run shooter
