Basic Logic Problem

Archive: 6 posts


Hi guys,

I have been struggling with this for 2 days now and I cannot figure it out.
Im building a puzzle consisting of 3 switch buttons, 3 lamps and a door. Every lamp must be on for the door to open but there is a catch.
The switches must be activated in order which is 2,1,3. So the player first has to activate switch 2, lamp 2 goes on. If the player tries switches 1 or 3 at first nothing happens
After switch 2 the player must activate switch 1, lamp 2 and 1 will be on. If the player activates switch 3 instead of 1 lamp 2 will go off again forcing the player to first activate switch 2 again.
Once the player has activated lamps 2, 1 and 3 in order the door opens.

How would I build this? I have tried and xor, not switches and batteries but I cannot get it right.
Later in the level I want to increase the number of lights in a next puzzle but for now im still struggling to build this setup. Thanks for the help

I believe the brilliant comphermc has made a couple of tutorials (Part 1 (http://www.youtube.com/watch?v=nCryeXkKpDQ) and Part 2 (http://www.youtube.com/watch?v=Yr63uFrRNS8)) on this subject 2012-05-24 11:35:00

I made the switch the way suggested in the tutorial. The door works perfectly. Now the only problem is that I cant get the lights to work so now the player has no clue if he/she is doing the right thing.
To add the lights I have tried linking them from the colored wires in the video, this turns them on but if you use the reset signal to turn them off again it doesnt work because the reset signal is on all the time.
Can anyone point me to a way on how to implement lights that show the players progress to unlocking the door?

You can use Counters with a Target Count set to 1.
Wire the "light on" signal into these, and wire the reset signal into the Reset input on the counters.

Wow, that was simple in the end. Spend 2 days fiddling with selectors, ors, ands and battery's.
Thanks for pointing that out, have a nice working puzzle now.
