Ah! An open sector... When I tried joining the sectors a while ago, nothing happened.


.=======.
=--------=
=--------= <--- Let's call this 'Sector 1'
=--------=
=--------=
.=======.
=--------=
=--------= <--- Let's call this 'Sector 2'
=--------=
=--------=
=--------=
=-------=

= - Walls.

. = Vertices.


I pressed the 'J' key in Sector 1 then pressed it again in 'Sector 2' but the wall that divided the sectors didn't turn red.

I have read Jonah Bishop's Map FAQ. And I use that to help me.

I already knew how to edit sectors...I finished my first map... I understand Hitags and Lotags, what sprites do what. I know how to make doors, enemys, masked walls and other things. What I don't understand is how BUILD's programmed.
