Article contents:== raylib [[toc:]] === Description Bindings to the [[https://github.com/raysan5/raylib|raylib]] game library version 5.5. These are not complete yet, but all of the functions I commonly use are ported over. It's a very thin wrapper around the raylib C library that hopefully has minimal performance drawbacks. Types such as {{Color}}, {{Vector2}}, {{Vector3}}, and {{Rectangle}} are represented as [[https://wiki.call-cc.org/man/5/Module%20srfi-4|SRFI-4]] vectors to keep the memory managed by CHICKEN. See [[https://github.com/raysan5/raylib/blob/master/src/raylib.h|raylib.h]] for more info on each function. === Requirements * foreigners * raylib c library (should be visible via -lraylib) === Documentation ==== Color interface <procedure>(make-color R G B A)</procedure> Represented as {{u8vector}}. ==== Vector interface <procedure>(make-vec2 X Y)</procedure> <procedure>(vec2-x V)</procedure> <procedure>(vec2-y V)</procedure> <procedure>(make-vec3 X Y Z)</procedure> <procedure>(vec3-x V)</procedure> <procedure>(vec3-y V)</procedure> <procedure>(vec3-z V)</procedure> Represented as {{f32vector}}. ==== Rectangle interface <procedure>(make-rect X Y W H)</procedure> <procedure>(rect-x RECT)</procedure> <procedure>(rect-y RECT)</procedure> <procedure>(rect-w RECT)</procedure> <procedure>(rect-h RECT)</procedure> Represented as {{f32vector}}. ==== Texture interface <procedure>(make-texture)</procedure> <procedure>(free-texture TEXTURE)</procedure> Allocates C struct in unmanaged memory ({{C_malloc}}).
