As with the function vertex_create_buffer(), this function will create a new vertex buffer. This is a special grow buffer created by GameMaker which is pre-formatted for use when building primitives for use with shaders. You can specify an initial starting size for the buffer (in bytes) and it will return an index for the buffer which should then be used in all further calls to the buffer.
vertex_create_buffer_ext(size);
| Argument | Type | Description |
|---|---|---|
| size | Real | The initial size of the buffer (in bytes). |
v_buff = vertex_create_buffer_ext(1024 * 1024);
The above code will create a new vertex buffer, initially 1MB in size, and store its handle in the variable "v_buff".
