A component based game engine written in Common Lisp for modern OpenGL (4.3+).
NOTE: This engine is still in construction, however, it is almost ready for game making. The developers (psilord and mfiano) hang out in #lispgames on freenode, and specifically ##hacker-theory on freenode. Stop by if you want to help or see how to run what we currently have, or just to say hello.
Writing a game is a difficult thing. So we've created a system and work flow that helps you describe the elements needed to write 2d or 3d games. We designed several domain specific languages that make it easier to describe, manipulate, and use assets commonly found in game making. Such assets are, but not limited to, textures, materials, shader programs, and scene trees of actors that are available for instantiation. Virality Engine also knows how to accept input from keyboards and most joysticks and gamepads.
The component system is a hybrid model between an ECS and an object model. The components are defined similar to CLOS defclass, and regular generic methods can be used with them. Components are added to Actors which represent game concepts like players, scenery, effects, etc. We define a component protocol invoked by Virality Engine to move your components to the next state and render them each frame.
This system is not yet available to be installed automatically with Quicklisp. To manually install using Quicklisp, clone this repository into your local-projects directory.
To start an example that is already present in Virality Engine, issue the following in your REPL:
(ql:quickload :virality.examples)
(virality.engine:start :scene 'virality.examples:damaged-helmet)
;; ESC exitsThere are many more examples.
