Dear experts, I am a very newbie of Game maker. I know how to use sprite and object together to make them move or collision event, but I want to make a object with a drawn shape (a custom polygon). I tried to draw a polygon with [draw_primitive], [draw_vertex] but it is only a shape on the screen and it doesn't collaborating like using sprite+object. I want to dynamically create objects with various shapes. (like every time random polygon + moving and collision)) Can someone let me know how to achieve this?
