Zone Lines?

[blindaviator]

I have been trying to figure out how setting up zone lines works... Are they configurable or are they hard-coded??

If they are configurable I cannot, for the life of me, figure out how they are working... I have tried everything I can think of to set one up but nothing seems to work... Can someone point me in the right direction??

I know it's possible to setup clickable objects for doors or zones but I want to setup one that is invisible just like most zone lines are...

Any help would be appreciated..
