buffer_copy_from_vertex_buffer(vertex_buffer, start_vertex, num_vertices, dest_buffer, dest_offset);
| Argument | Description |
|---|---|
| vertex_buffer | The index of the vertex buffer to copy from. |
| start_vertex | The starting vertex. |
| num_vertices | The total number of vertices to use. |
| dest_buffer | The index of the buffer to copy to. |
| dest_offset | The offset position to copy the data to (in bytes). |
Returns: N/A
This function can be used to copy some (or all) of the vertex
data stored in one vertex buffer into a previously created regular
buffer. When copying from a vertex buffer into a regular buffer
with this function, both buffers must have previously been created
(using the vertex_create_buffer()
and buffer_create
functions, for example). You can specify the range of vertex data
that you wish to copy into the buffer, where the start vertex can
be anywhere between 0 and the number of vertices -1, and you can
give the number of vertices from that point on to copy. You can use
the function vertex_get_number()
on the vertex buffer to get the total number of vertices stored.
Finally you give the buffer index to copy the vertex data into, as
well as a data offset to define the position to copy the vertex
data to in the destination buffer.
var v_num = vertex_get_number(model_buff);
buffer_copy_from_vertex_buffer(model_buffer, 0, v_num - 1,
player_buffer, 0);
The above code will copy the vertex data stored in the vertex buffer indexed in the variable "model_buffer", and then paste it into the buffer indexed in the variable "player_buffer".
