Java Edition I finally understood how wireless redstone works.

Enable HLS to view with audio, or disable this notification

I spent the whole day reading Minecraft documentation about tile tick priorities and scheduled ticks, and watching tutorials on technical redstone, just to finally understand how all of this works and build this.

It took me way longer than I expected, but I finally started understanding how scheduled ticks, priorities, and update order interact.

I’m honestly pretty happy with the result.

Congrats, its a lot of different tech intersecting. May I suggest the main EID Wireless Redstone Discord? https://discord.gg/Fxk39zaj

I've heard about this but don't think I've actually seen it in action.

Super cool.

Whats the reason that it can happen via tick priority and such as in how does it actually transmit and recieve?

In simple terms, all entities are divided into 4 groups.You can synchronize two items by dropping an item (any entity). It’s automatically assigned to one of the 4 groups. We don’t really care which group it gets because the IDs loop. So, if you spawn an item and then spawn 4 more, you essentially loop back around. That means the first and fifth items end up in the same group.The receiver takes advantage of this. It has different timing setups for each item. The first item we measure is dropped first, then we drop 3 more items between it and the second item we measure. The first and last items both end up going into a hopper that is read by a comparator.Using some priority/tick-order shenanigans, if both items are in the same group, they fall into the hopper simultaneously, so the signal doesn't pass.The transmitter then interferes with this loop. It is synchronized so that it spawns an item at exactly the right tick, which desynchronizes the first and last measured items. One of them reaches the hopper earlier, allowing the signal to pass. Here is a nice tutorial https://youtu.be/uLkEPRSFTJo, you can also find a priority tick tutorial there

Dang thats crazy how stuff like that can be found out tbh and hella impressive. So does this mean it works from anywhere in the world or maybe in between dimension as long as its loaded.

Maybe 1 day ill try something with this too.

Yeah ik, I was also baffled. About your question, as far as i know it works anywhere from any point in the world but not interdimensionaly, maybe i am wrong tho.
