As with the function vertex_create_buffer, this function will create a new vertex buffer. This is a special grow buffer created by GameMaker Studio 2 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 a "handle" (index) for the buffer which should then be used in all further calls to the buffer.
|size||The initial size of the buffer (in bytes).|
v_buff = vertex_create_buffer_ext(1024 *
The above code will create a new vertex buffer, initially 1MB in size, and store its handle in the variable "v_buff".
