I used Wad2Map in the Goodies. It was a Chex Quest conversion (an interesting procedure with the conversion). If any of you have played this game, then you should know about E1M1. Well in the room that you need a blue key to enter, there was an error in the lock. The door would only open from the back side. I have only put in one locked entrance (there are two, as you may remember) so I can go around this door without the key. I used the high tag 212 and the low tag 1 for sprite 130. The low tags match and sprite 4 has a high tag of 0. I've been reading the FAQ of the build and I can't think of anything else to do. Also I am using Mapster 32. I don't know if this makes a difference in process from Build.

If there's a question here, it's missing one of those --> ?.

Anyway, I assume you want to duplicate the effect of having a door openable from only one side? I discovered how to do that once (not claiming to be the first), it's in a thread called "rendom trivia" or something similar...

This looks a little spammy. QXZ, if there is a person there, just play Chex Quest with ZDoom or GZDoom instead of screwing around with a conversion that will always be imperfect.

taking a wild guess. a door that is a child sector inside a parent sector that is tagged with a one time sound can only be opened after the one time sound is triggered (i.e. you have to enter the parent sector before the door will open)
