So I had to go through a grueling process of rebuilding redstone for my Pirates of the Caribbean map and thought it might be a cool idea to make it into a series.
The original map took months of effort to create and, while functional, was too laggy to be used practically. The changes I make to it here will make it not only less laggy, but will enhance the already badass system.
As I said, apologies if this is known already. I was derping with redstone recently and came up with this. It was originally intended for my foosball game, but I ended up not using it due to the glitchy nature of 18 stacked minecarts.
Very useful, tile-able and 1 wide, what more could you ask for?
