zportal vertical

[Darklord328]

im trying to figure how someone has made an endless room showing water way off into the distance short walls, but upon entering the sector its big shooting endless stream of projectiles being shot through that portal, https://www.youtube.com/watch?v=AEGPdDaXmAM this link right here will demostrate it, i just don't know how this got pulled off i'd like to know how this was executed and whatnot.. i hope this makes sense, *im half-asleep.*

So, wake up

This is done with portals. The trick is that the big room inside small cube is in completely different place, linked by action special 156 - https://zdoom.org/wiki/Line_SetPortal

ok, so i've looked through this, to me, this does not make no sense to me. has anyone made a tutorial map? for the vertical zportal?

Maybe you should specify what exactly is not clear to you. What does not make sense, what you don't understand?

i totally did not see that, i was so half a sleep that night, and now its making sense to me.

question is, how can i pull this off, with a small cube with a big room going from start to finish.
