Sector portal issues

[Sneezy McGlassFace]

Sigh, yet another newbie having troubles with portals..

Here's the deal: I've been working off this tutorial - Tutorial: All-In-One Portal Guide for GZDoom - Dragonfly's Doomworks and followed it to the letter, recreating it as exactly as I could. And I can see the other sector in game, yay. I can't shoot through it, can't move through it, monsters don't see me through it either, boo. Line teleporters work great btw.

 

Gzdoom gives me this message when running the map:

MAP01 - Entryway

Line 16 has no first side.
Line 17 has no first side.
Line 18 has no first side.
Line 19 has no first side.
Line 17's right edge is unconnected
Line 19's right edge is unconnected
4 missing segs counted in GL nodes.
The BSP has to be rebuilt.
Portal between sectors 0 and 0 has both sides in same group and will be disabled
Portal between sectors 0 and 0 has both sides in same group and will be disabled

Lines 16 through 19 are anchors so there's clearly something wrong with them. Also, worth noting that I can see the anchors in the lower sector and they block movement.

 

I watched numerous tutorials and read the zdoom wiki on Portals and I'm just lost. There's something I'm doing wrong and I don't know what.

Any help is much appreciated, I'm working on a map that is expected to utilize sector portals a whole lot, and I put a bunch of time and work into it without having the portals working at all. Kinda foolish but you know, that's me being me.

 

Anyway, happy new year everyone! 🎉

I find that splitting the linedef on one side of the portal sector into a couple of tiny lines, and using them as anchors works best for me - I tried the disconnected lines method and couldn't get that to work, but having the anchor linedefs as part of the structure seems to work well.

It's my learning/demo map of line and sector portals.

I'm not sure how you managed to do that, but your anchor lines don't have sidedefs. So they don't belong to any sector. Go to the linedefs editing mode and check the "Front Side" and "Back Side" checkboxes for all of them,  and assign the proper sector numbers. In your example the anchor lines in the lower portal part should belong to sector 1 and in the upper portal part should belong to sector 3.

Funny thing, I'm editing in Eureka on Linux, and I never managed to make disconnected lines to behave. They're highlighted in red, indicating they're not connected to a sector.

 

Okay, you won't believe what fixes it - I put another line in the sector, and it updates or something, and now it works just fine. The lines aren't red, and sectors are connected as they should.

Uhh... cool, I gues? ¯\_(ツ)_/¯

See for yourself/yourselves

Ahahaha! That's exactly it!! Eureka doesn't like linedefs flapping about in the breeze. So you can make the outline the anchor! That's a good news. Seems much better than the hacky workaround I found just a minute ago - splitting the sector, which somehow updates the lines to belong to the sectors they're in. Cool!

@HrnekBezucha, glad you got it sorted!
