al_build_shader3alleg5
Allegro 5 api
Usage
-
#include <allegro5/allegro.h> bool al_build_shader(ALLEGRO_SHADER *shader)
Overview
This is required before the shader can be used with al_use_shader(3alleg5). It should be called after successfully attaching the pixel and/or vertex shaders with al_attach_shader_source(3alleg5) or al_attach_shader_source_file(3alleg5).
Returns true on success and false on error, in which case the error log is updated. The error log can be retrieved with al_get_shader_log(3alleg5).
Note: If you are using the ALLEGRO_PROGRAMMABLE_PIPELINE flag, then you must specify both a pixel and a vertex shader sources for anything to be rendered.
