Doomsday Engine WAD Error

[Da Eediot]

So, I made this WAD in Doom Builder 2. And it's working fine when I test it on Doomsday Engine. But I later make this one room completely dark, and when I test it, I get an error that says:

Application terminated due to exception:
Uncaught exception during loop iteration:
[MissingSectorError] (Line::Side::sector) No sector is attributed

I tried to fix it by changing the lighting in the WAD, but that didn't work. And I tried to use my .bak WAD files, but they still got that error. Please help!

Given the error message, it seems you have a sidedef without sector reference. Run DB2's error checker to see if it finds it.

What else did you change besides the darkness? That shouldn't break it unless there's some weird code in the engine that stops it rendering 0 light sectors properly.

How do I run Doom Builder 2's error checker?

I'm 99% certain I only changed the darkness. I can't remember changing anything else in that room. Do you know what causes that error?

The so-called "Map Analysis Mode" (= Error Checker) is available as a "V" icon on the top panel, next to "Find and Replace" (magnifying glass icon).

Oh. I found it. Thank you. I'm using it now, so I'll tell you if it fixes my problem or not.

Oh my god! It works now! Thank you! :D
