I made this map where you have to take a soccer ball and drop it into a hole and then it opens a door. Its pretty simple I know, but I want to know better ways to make doors open (in a cool way)
You can try to experiment and try to find new interesting ways to open doors. If you just want a list of ways to open doors, go to forging 101, it goes into more detail there.
Soo.... this is a switch you're talking about, right? Your question is really vague. Try giving us a few pictures of your own switch, so we can see what you've already done. If you are really interested in switches, talk to Goatnuts or Adelyss, or check out h3artificer.com. They focus on switches there.
