SRB2 doombuilder(walls)

[Aaron]

I am using SRB2 Doombuilder, when I try to make sectors I can usually just walk through or jump through walls with 1 sidedef. I have tried all DB's node builders. How do I prevent this?

Did you add thok barriers? They prevent walking trough walls.

yeah THOK Barriers!
They are like the REAL walls that are THICK,
this way when you try to walk through one wall,
other one stops you!
but i can't make more than one FOF's because I get error messages,
then SRB2DB gets all mad and kicks me off.
(without saving my level!)

...that's because you need to make them manually. You can only use that tool once per map, but if you make them manually, you can have as many as you need. It's not even that hard.

For making thok barriers, all you do is make a giant square around the map, then set the ceiling and floor heights to the same value.

Although, if you're making a large map, a square isn't the way to go. You'll just want to make a sector that surrounds the outer edges of the map.

Actually, that's not why Thok Barriers work. The reason why you can walk through the walls when there isn't a Thok Barrier is because the edge of the level has no adjacent sector to compare the height of the level to. Thok Barriers prevent this from happening because they are basically a room that wraps around the entire level, with the floor and ceiling at the same height. Because of this, you can't actually reach the "edge" of the level, because the walls of the outermost sector have no opening in them.

Shouldnt this be in editing help? Also try making a out line of the intire level. Look at other levels.

Basically, Thok Barriers don't allow you to pass for the same reason you can't pass through a ceiling or floor of an adjacent Sector.
