I think the relative transition is working fine now. I´m using a sort of global coordinates to locate a certain map instead of map id.
I was thinking now wich way would be the best way to display the new tiles for the new map, right after the map change.
I am using a panel array that is filled during runtime with the tiles graphic matching a certain character read from .txt file.
There is a second array with the same way. Then (during the map change) I check wich one has the bigger layer value and just exchange them (making the "tiling" process again with the new .txt file to be displayed).
Is there a better way?
