Bioware website doesn't seem to be working so I thought I'd ask you guys.

I'm trying to create a trigger. I have it scripted and want to paint it into the level. However, onece I've finished clicking to make a 2d box all I can do is keep creating lines, and If i click anything else in the toolset again, it disappears from the level and I have to repaint it. How do I make it stay??

If you doubleclick after you reached the last point of your polygon, the editor will create a polygon from your lines, and draw a rectangle around it aswell.

You're a diamond! thanks
