Most likely you will just put a pointer into room_index_data to the new tracking data type. Only that pointer will be allocated with the room, and it doesn't take up a lot of space. Then, as the people walk through the rooms, you will have to allocate the new data type (with perm_alloc if you want to keep a separate free pool of empty tracking structures, or with alloc_mem if you want to use the general memory pool) and link it into the room's list. --Palrich.
