For some time, i've been thinking that Minecraft could use ziplines for the cases when you build a high tower or a mountain home. They could come as two poles connected with a rope: you leave one pole on top of your home, then plant another in the place you want to end up when you take the zipline. They could even be deployable with a bow for quick escapes, even though i imagine it would be harder to implement than just two poles with a zipline. I wouldn't know how difficult it would be to implement in the game, but the idea itself seems like a useful option.
It's against the rule to be saying there is a mod for that...
But to stay on topic, Jeb was thinking about putting this in minecraft.
Now that is just amazing. Epic winning.
can't wait to see what this looks like if/when they implement it in-game!
