What if I just used the same Matrix over and over?
Like depending on the value of M will depend on which map loads and displays.
Then the character placement.
Or just have a value put up in the matrix, where if the tile value 3 is stepped on and M is equal to a certain amount, just change the map value and re-run the map loading..
I might be over-complicating it though :I
Slow program is slow x3

Well a game with only 1 kind of map would be kinda boring I think . However if you mean like what I did in Mana Force then you should be fine
