Character gets stuck

When playtesting my chracter always gets stuck on the carpet and will not go behind furniture. Can someone help me please?

Screen Shot? Sounds like you might have used the tile set wrong

Either your passability settings have been messed up in the database, or you are using a tile that isn't(by default anyway) what you think it is for a carpet.

In both cases, go into the database and click on the "Tileset" tab, select the set you are using for the map you are having trouble with and customize the "Passage" settings. A circle means you can walk on it, an X means you cannot walk on it, and a star means you can walk behind/under it. For the furniture you would first want a star, then click on "Passage (4 dir)" and remove the down arrow which will make the front edge impassable while allowing you to walk through the rear and side edges. Effectively giving the appearance of walking behind it, at least with the taller objects like bookcases.

The black areas are the impassible parts

From what I can see, you used a wall-top as the wooden floor. That can be walked on, but requires steps/ladder to access.
