Any tips on making multi level houses? once i make the second floor the first floor is no longer "walkable" i tried making the floor wadable but that didn't seem to help
Can't be done in this engine cleanly. You have to "instance" one of the floors.
1.
Basically reserve a big patch of terrain away from your main map. Then place an equivalent sized wall piece you want to use for the second floor. Copy/paste will even work if it's supposed to be exactly the same layout as the bottom floor.
2.
Then place a region trigger around the instanced upper level house (so you can't see outside the "instance").
3.
Throw a camera lock trigger on it (optional).
4.
Place a point trigger near the stairs in the instanced area. Give it an obvious name (I usually do something like LEVELNAME_Point_StairDown_2ndfloor)
5.
Then on your stairs on one end, set an "onuseaction" on the sidebar as Teleport. Select the trigger on the other end. Then do the inverse on the other stairs.
Now you have an instanced 2nd floor.
Maybe I'll do a tutorial on this, though there might be an old one for the D:OS 1 editor laying around. It's the same process.
One other tip is, if you look at fort joy, the first floor of the castle is actually the instanced floor and the 2nd floor is the one you walk on. This layout might work better for you depending on how you already made the house.
