Finally, I have changed the way of control in building.
It is quick to build a room now,especially when the number is large.
Besides, I removed the board of Adventurers Status.You can click a adventurer directly to show the detail.
Why did I do this?
Because I want to create more large dungeon.You can define the dungeon's width and height yourself in the future.The dungeon will have different "terrain".
It will be more interesting.
