I want to make a 3x3 entrance to a lava pit, that hides a secret base underneath. The pit can be at most a 7x7 area. I envision something where it clears a 5x5 area, then a 3x3 door opens up, but I'm really struggling to make it happen.

I have attached an image of my honestly pretty bad attempt, as well as my ideal lava look. Any help would be appreciated!

wana prank a friend is there such a thing as a orbital egg cannon?

I have this 3x3 lava door, making use of an old mumbo design plus some to block off lava.

There's one issue though, the lava gets in the hole, and makes getting inside take forever, AND destroys the torches that power the pistons. How can I prevent the lava from getting in or remove it before it gets far?

I attached a picture of the current design, if you need any other angles let me know and I will oblige.

IDK what to say i just saw a chelenge to create the smalest not gate only with repeters and redstone dust. idk is this small or big but the one i saw wsa like 5 blocks biger or somthing

so basically, Gerg's overflow but the redstone didn't work on bedrock so I had to make it work.

I’m currently working on the feasibility on a system of autonomous chest minecart.

The goal would be to allow players on my server to send chest minecart from a certain station to a specific station on a single loop track

E.g

A — B — C — D

A player send a minecart from A to C
Another send a minecart from A to B

My first experiment has been to use fullness to represent the « code » of each station (a shulker box + one token item represents a single of 1 from the comparator)

Do you have more efficient solution ?

Does anyone know the best way to make either a 3x1 door or just a 2x1 with the bottom 2 logs?

Pretty much everything in the question. I know world eater exists but they''re not made to take the stuff and I don't know much about technical vanilla minecraft tbf.
Thanks for the help !

Hi! I built this auto bottle refill for my clay farm and I can not figure out how to stop bottles flowing right through it when they should stop at the dispenser by the piston and only continue when they are empty after being used, any help is appreciated!
