vertex_format_begin

Before you can define your new vertex format you must tell GameMaker that you're doing so using this function. You must call this first, then define the format values using the appropriate functions, and finally call vertex_format_end() to finish the definition and return the new format "handle".

Syntax:

vertex_format_begin();

Returns:

N/A

Example:

vertex_format_begin();
vertex_format_add_colour();
vertex_format_add_position();
my_format = vertex_format_end();

The above code will create a new vertex format with just colour and position values and then store the format id in the variable "my_format".
