Vertex_get_buffer_size - hpgDesigns/hpgdesigns-dev.io GitHub Wiki

Description

Gets the size, in bytes, of the given vertex buffer and returns it.

Parameters

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

Return Values

unsigned: Returns the size of the vertex buffer in number of bytes.

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 byte size of the entire vertex buffer after it has been filled
var byte_size;
byte_size = vertex_get_buffer_size(static_buffer);
