A Ruby 3d OpenGL game library inspired by the Lua Love project, a fun little 2d game engine.
The project name
hate is a parody of the inspiration.
Other inspirational Ruby game projects worth checking out (and much, much more feature complete, albeit only 2d).
gem install hate
Your game requires a
main.rb file at the root of your game directory which
hate will execute. There is an example game located in the example folder which shows how the basic methods of the system work. At the moment you must wrap all the methods in a module like so.
module Hate module Game # methods end end
These are predefined and overridable methods which the engine implements. Any logic you write within them will get execute by the engine.
Anything defined in here is initially loaded at system startup.
Anything in here gets called every second draw call. In theory physics and non draw frame game updates would go in here.
Draw logic for all of the objects in your scene.
Any keys which have been pressed by the user as a byte character.
self.mousepressed(x, y, button)
The x, y position and button pressed for the mouse.
self.mousemotion(x, y, xr, yr, state)
The x, y position, x, y position at click, and button state of the mouse.
The quit callback.
Currently this has only been tested on OSX using MRI 1.8.7 and MRI 1.9.2. Unfortunately ffi-opengl under Rubinius and jRuby doesn't seem to be operational.
- Quit doesn't exit cleanly.
- The framerate slows down when the mouse is moved.
- The framerate isn't locked to a constant rate.
- The full system isn't currently implemented, and the engine is a continual work in progress.
