Sector Behavior

[Herculine]

I'm currently working on my first ever Doom II map for ZDoom using Doom Builder to edit it. I came across a weird problem today in two specific sectors while testing. While standing in these sectors shooting point-blank at an enemy my shots would not connect, as if there was an invisible wall between us. I very carefully examined all line and sector tags and properties in the editor but could find nothing that would cause this problem and therefore also could not correct it. The only way I found to get rid of it was to copy and paste the room I was building to another portion of the map. After that everything worked fine. Does anyone know what might cause this or how to fix it without having to start all over?

This may be it

That's exactly the sort of thing. I couldn't find anything there about how to fix it though, or what causes it. Thanks for the help though!

It will be impossible to tell what was the problem without the original bogus map. However, I'd speculate a malformed nodebuilt lump could be the explanation, since the last time I've seen a report of this kind (that was with monsters unable to see the player despite being in the same sector and attacked), that was the explanation.

Could you just select the whole map and move it over a bit?

Once upon a time, I made a Heretic map comprised of a couple of huge sectors for testing something unrelated.

When I fired a Wand or Dragon Claw shot, whilst flying in this map and with my back to a wall, my shots's would hit an invisible barrier a short distance in front of me.

I was told by someone knowledable that this was because the Doom engine has issues with maps that are only a couple of sectors. Though I didn't ask for a technical explanation.

Yes, the only solution I was able to come up with was to copy and paste the entire building to a different part of the grid and then delete the original. After that everything was fine. I'm just lucky it wasn't a part of the main portion of the level, because that would have been thousands of sectors to copy and paste! I'm getting close to having the thing completed and I'd really hate to trash the entirety of several months work just because of some nodebuilder error bug. Thank you all for the info!
