Apologies if there's already a thread, I couldn't find one.
I've a set of platforms on pistons and I'd like to control the direction of them from two seperate buttons or 2/3 way switches.
e.g. The platforms are raised, you lower the platforms from switch A, cross them, then pull switch B and they raise back up to get you to point C. Easy enough, but I'd like the player to be able to raise and lower the platforms from both switches......???
