Spear

Spear is a simple 2.5D game engine I have been working on since I started learning Haskell. The project's goal is to put what I learn into practise, to explore how far I can get with Haskell and if the results are decent enough, to build one or two game demos along the way.

Installation (Ubuntu)

Install dependencies, then build with cabal:

$ sudo apt install libxxf86vm-dev libglfw3-dev
$ git clone https://github.com/jeannekamikaze/Spear.git
$ cd Spear
$ cabal build

Run a demo:

$ cabal run pong

Features

Application and Input

Easy way to set up a window with the desired OpenGL context version.
Raw polled, toggled and delayed input.
High resolution timer.

Assets

MD2 and OBJ model loaders.
BMP image loader.
Assets backed up by Resource for automatic (and optionally, manual) deletion.

Collision

Simple collision library featuring AABBs and bounding circles.

OpenGL

OpenGL >=3 wrapper library.
OpenGL resources (VAOs, buffers, textures, etc.) backed up by Resource for automatic (and optionally, manual) deletion.

Math

Vectors, matrices, quaternions, cameras, segments, rays, etc.
The Spatial2 and Spatial3 type classes for objects that can be moved around in 2D and 3D space, respectively.

Render

Static and vertex-animated model resources, compiled into a VAO for efficient rendering.
Static and vertex-animated model renderers. Vertex animation is done in a vertex shader.

Scene

Automated loading of scenes and scene resources as described by scene files.
