Vertex_get_number - hpgDesigns/hpgdesigns-dev.io GitHub Wiki

Description

Gets the number of vertices specified in the given vertex buffer.

Parameters

Parameter	Data Type	Description
buffer	integer	Index of the vertex buffer.

Return Values

unsigned: Returns the number of vertices specified in the given vertex buffer.

Example Call

// add a triangle to a vertex buffer we want to be static
vertex_begin(static_buffer, vf_color_position);
vertex_color(static_buffer, c_red, 1);
vertex_position(static_buffer, 100, room_height - 100);
vertex_color(static_buffer, c_green, 1);
vertex_position(static_buffer, room_width / 2, 100);
vertex_color(static_buffer, c_blue, 1);
vertex_position(static_buffer, room_width - 100, 100);
vertex_end(static_buffer);

// demonstrates querying for the number of vertices in a vertex buffer after it has been filled
var vertex_count;
vertex_count = vertex_get_number(static_buffer);
