12 ALLEGRO_BITMAP* texture, ALLEGRO_INDEX_BUFFER* index_buffer,
13 int start, int end, int type)
14
16 Draws a subset of the passed vertex buffer. This function uses an
17 index buffer to specify which vertices to use. Both buffers must not
18 be locked. Additionally, to draw onto memory bitmaps or with memory
19 bitmap textures both buffers must support reading (i.e. they must be
20 created with the ALLEGRO_PRIM_BUFFER_READWRITE).
21
22 Parameters:
23
24 · vertex_buffer - Vertex buffer to draw
25
26 · texture - Texture to use, pass NULL to use only color shaded prim‐
27 itves
28
29 · index_buffer - Index buffer to use
30
31 · start - Start index of the subset of the vertex buffer to draw
32
33 · end - One past the last index of the subset of the vertex buffer to
34 draw
35
36 · type - A member of the ALLEGRO_PRIM_TYPE(3) enumeration, specifying
37 what kind of primitive to draw. Note that ALLEGRO_PRIM_LINE_LOOP and
38 ALLEGRO_PRIM_POINT_LIST are not supported.
