Wow. I wrote up a small tutorial to help people create terminals with more than one message in them. The day after I released it, Bo Lindberg sent me mail explaining that I'd taken the hard road, and that there was an easier one. (He also sent along a quick demo map.) I planned to add his info to the tutorial, but backburnered it... Two days later, I got mail from Jason Harper, who explained that your options in this field are nearly unlimited, and sent along a demo map, with a promise of a full tutorial to come. Here it is... and if this technique interests you, you need this file. The example map has a total of 8 different messages, depending on what combination of three switches are thrown. From the creator of "Missed Island", a map that revealed a Forge master at work, comes one of the most informative demonstrations I've seen of an advanced mapmaking method. Download this, learn this, incorporate this. Make cool maps. Give Jason more stuff to play, and more incentive to teach new groovy stuff.
