sets a callback for a certain event. this is very useful for event-oriented applications. event callbacks will not interrupt each other or the mainloop.
Defining callbacks will only work after calling s3d_init() |
void obj_click(struct s3d_evt event) { printf("object id %d got clicked", *((unsigned long *)event->buf)); } ... s3d_set_callback(S3D_EVENT_NEW_OBJECT, obj_click); /* this will tell you when a object got clicked */
