al_draw_indexed_buffer - Allegro 5 API


#include <allegro5/allegro_primitives.h>
int al_draw_indexed_buffer(ALLEGRO_VERTEX_BUFFER* vertex_buffer,
   ALLEGRO_BITMAP* texture, ALLEGRO_INDEX_BUFFER* index_buffer,
   int start, int end, int type)

    

Draws a subset of the passed vertex buffer. This function uses an index buffer to specify which vertices to use. Both buffers must not be locked. Additionally, to draw onto memory bitmaps or with memory bitmap textures both buffers must support reading (i.e. they must be created with the ALLEGRO_PRIM_BUFFER_READWRITE).

Parameters:

vertex_buffer - Vertex buffer to draw
texture - Texture to use, pass NULL to use only color shaded primitves
index_buffer - Index buffer to use
start - Start index of the subset of the vertex buffer to draw
end - One past the last index of the subset of the vertex buffer to draw
type - A member of the ALLEGRO_PRIM_TYPE(3) enumeration, specifying what kind of primitive to draw. Note that ALLEGRO_PRIM_LINE_LOOP and ALLEGRO_PRIM_POINT_LIST are not supported.

Returns: Number of primitives drawn
