Drawbridges. Beware WR:CBE, though, because it's very crashy. My world is currently broken, maybe because of WR:CBE, maybe because of drawbridges, so back up before you build.I am looking for a way to open a secret door when I approach a wall, I'm pretty good on player detector methods though I'd love to hear more because I'm sure I missed some. What I'm really looking for is a method of opening the wall. I'm using the Monster pack so there are no Redpower like frames which is how I had done it in the past. I am not equipped to do MFFS so that's out, though I do believe it has blocks that would satisfy my needs.
