#+TITLE The Chickadee Game Development Toolkit
* About
Chickadee is a game development toolkit for Guile Scheme.
Here's a simple hello world program:
#+BEGIN_SRC scheme
(define (draw alpha)
(draw-text "Hello, world!" (vec2 260.0 240.0)))
#+END_SRC
The above program can be run with =chickadee play=:
#+BEGIN_SRC sh
chickadee play hello.scm
#+END_SRC
Here's what rendering a sprite looks like:
#+BEGIN_SRC scheme
(use-modules (chickadee graphics sprite))
(define sprite (load-image "images/chickadee.png"))
(define (draw alpha)
(draw-sprite sprite (vec2 256.0 176.0)))
