Welcome to doodle - A minimal 'framework' for your games, visualisations etc. Doodle is written in CHICKEN scheme, which is available at http://www.call-cc.org. It abstracts simple graphic rountines and window handling on top of cairo / SDL which should make visualisation tasks and exporting these drawings as well as writing games more fun and easy. doodle also provides a simple event loop model which has got its inspiration from the LUA Löve framework, making it easy to do animations and move sprites around. Doodle comes with an experimental (which means undocumented) sprite collision detection mechanism. To install doodle you can use CHICKEN schemes chicken-install tool: $ chicken-install doodle Examples: - The tennis game has been the first game written in doodle.
