* About
- Chickadee is a game development toolkit for Guile Scheme. It comes
- with built-in support for 2D/3D games using SDL and OpenGL, but is
- generic enough to be used with any I/O backend, in case you are
- writing a text adventure or want to render your Roguelike to a
- terminal!
+ 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)))
#+END_SRC
+ #+BEGIN_SRC sh
+ chickadee play sprite.scm
+ #+END_SRC
+
