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.
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
- Easy way to set up a window with the desired OpenGL context version.
- Raw polled, toggled and delayed input.
- High resolution timer.
- MD2 and OBJ model loaders.
- BMP image loader.
- Assets backed up by Resource for automatic (and optionally, manual) deletion.
- Simple collision library featuring AABBs and bounding circles.
- OpenGL >=3 wrapper library.
- OpenGL resources (VAOs, buffers, textures, etc.) backed up by Resource for automatic (and optionally, manual) deletion.
- 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.
- 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.
- Automated loading of scenes and scene resources as described by scene files.
