How can i map rooms, that are overlayed in MUME?
MMapper uses two dimensional graphic canvas to display rooms and their connections. This basicaly means, that rooms can't overlay. If any room is under other one (for example bridge and river under the bridge), you have to select another free place on the canvas for one of that two rooms rooms. Connection arrows will be added by mapper automaticaly.
Why MMapper doesn't automaticaly connect to room, which is already on map and create new one with the same attributes?
Answer is simple. There are a lot of rooms in MUME, that have equal all attributes, which can be detected by MMapper. This basicaly means, that MMapper doesn't know for sure, if new room is or isn't already on map.
Why MMapper sometime goes out of synchronization with real position of my character in MUME?
Again, there are a lot of rooms in MUME, that have equal all attributes, which can be detected by MMapper. If character flees, portals, is transfered or does any other kind of movement, which direction is not known, and MMapper dont find exact room, it will go off sync. If automatical synchronization is on, MMapper will try to synchronize after each move or when examine or look command are send to MUME. Otherwise you can use _sync command, to try to sync.
