           Defining callbacks will only work after calling s3d_init()

            #include <inttypes.h>

            void obj_click(struct s3d_evt event)
            {
                    printf("object id %"PRIu32" got clicked", *((uint32_t *)event->buf));
            }
            ...
            s3d_set_callback(S3D_EVENT_NEW_OBJECT, obj_click);
            // this will tell you when a object got clicked
