Continuing the discussion from How to make a both-ways laser door:
This is just a repost of a reply, but made into a topic so people can easily find it.
Materials: 2x Zone, 1x Laser
- Resize the zone to fit the laser, use Change Size to change the size of the laser.
The icon should be near the laser (you should see a wire)
- Create a wire that goes from the zone to the laser beam.
Then, wire it so when the player enters the zone, the laser deactivates.
- Create a second zone, and put it directly over the first zone.
- Now wire it so when the player leaves the zone, the laser activates.
