asiri YaBB Newbies Offline Posts: 28	creating new objects at runtime Dec 18th, 2009, 8:31am   im new to processing.. i sw in one of the processing tutorials that you can create objects in "setup()"  and call them at runtime in "draw()". what if i want to create objects at runtime when it satisfies some condition. creating objects inside the draw() method doesnt seem like the best way .. any idea ? thanks in advance.
