al_set_shader_int_vector(3) Library Functions Manual al_set_shader_int_vector(3) NAME al_set_shader_int_vector - Allegro 5 API SYNOPSIS #include <allegro5/allegro.h> bool al_set_shader_int_vector(const char *name, int num_components, const int *i, int num_elems) DESCRIPTION Sets an integer vector array uniform of the current target bitmap's shader. The `num_components' parameter can take one of the values 1, 2, 3 or 4. If it is 1 then an array of `num_elems' integer elements is added. Otherwise each added array element is assumed to be a vector with 2, 3 or 4 compo- nents in it. For example, if you have a GLSL uniform declared as uniform ivec3 flow- ers[4] or an HLSL uniform declared as uniform int3 flowers[4], then you'd use this function from your code like so: int flowers[4][3] = { {1, 2, 3}, {4, 5, 6}, {7, 8, 9}, {2, 5, 7} }; al_set_shader_int_vector("flowers", 3, (int*)flowers, 4); Returns true on success. Otherwise returns false, e.g. if the uniform by that name does not exist in the shader.
