DukeMatch/SinglePlayer only effects?

[Haravikk]

Is it possible to make effects duke-match or single-player only? I've dug out an old project of mine which is a city level with a few major buildings in it that the player progresses through in a linear way. However, I'm hoping to open up some of the other "dummy" buildings and the streets so that it can be played as a DukeMatch. What I want to do therefore is put in effects such as ruined walls that only trigger on DukeMatch games, and will allow players to play on areas of the map that are inaccessible in sinlgle-player/co-op.

Is this possible without modifying CON code? The problem is I have some ways to and from buildings that are one-way, so you can't just back-track, meaning everyone would eventually end up stuck at the last area =)

Well, you can make cracks and switches (as well as all pickups like weapons) appear in multiplayer only by giving them a pal of 1 (Actually any pal works, but it just makes the map easier to navigate if you give them all the same pal)

Apart from that I'm not sure if you can make stuff only trigger in DM without con work.

You can make switches and other things only work/appear in multiplayer, yes, and if you use cons there's an ifmultiplayer command/check that you can use for different effects. So there's a lot of options.
