room_goto_previous() => Aller à la room précédente.
room_goto_next() => Aller à la room suivante.
Et un petit extrait de l'aide:
- Citation :
- room Index of the current room; can be changed to go to a different room, but you had better use the routines below.
room_first* Index of the first room in the game.
room_last* Index of the last room in the game.
room_goto(numb) Goto the room with index numb.
room_goto_previous() Go to the previous room.
room_goto_next() Go to the next room.
room_restart() Restart the current room.
room_previous(numb) Return the index of the room before numb ( -1 = none) but don't go there.
room_next(numb) Return the index of the room after numb ( -1 = none).
Voila, ça devrait suffire.
