I know normal tile entities are tickable in default. I'm using a BlockEntity and the only methods inside are for getting the data and save and loading them. Every time the power get registered, it will check if there is no other value to override the value. The delay points are triggered by a scheduled tick, but unfortunately scheduled ticks only occure in the simulation distance. The cable is intended to load the chunks on it's pathway. Maybe that can cause lag.

Not because nothing occures you might mean. The fiber cable does not do anything when the power is not changed. And when it is changed, it only calls the input, the output and a delay point.

After finishing the whole code of the block and the blockentity I decided to test it on the extreme using a superflat of fiber cables. This clearly didn't push any limits. Even when I power one of them I barely dropped any frames. I even tried powering them with a repeater. If you didn't already know, there is a limited amount of updates in that could all happen in one chain before the game crashes. So it is a succes.

But I was wandering if blocks that uses block entities would cause lag if you would use lots of them in your world. If I would have assumed that it doesn't, I would have used them in the first place.

I'm trying to make a mod that introduces fiber redstone cables. It is ment to be a lag friendly way to travel redstone signals over long distances instantly without loosing the redstone strength. They only travel straight and if they cross each other, those are seperated lines. I'm starting with just the basics like a cable that just connects to another. The problem is that if I start up the game, it gets stuck. When I runned it in debug mode, I noticed that it is infinitely looping inside the StateDefinition constructor. package net.migats21.redstonetweaks.block; import com.google.common.collect.ImmutableMap;

I thought using a block entity would be more laggy than using blockstates. But if I'm wrong, that might be a quick solution.

This is something that has haunted me from the start that I used minecraft forge mod loader. When the mod folder contains mods that are supported in a different version of minecraft, the game crashes and I need to delete them all. So that also means that I can't play forge on different clients if they are different versions. When there is a fabric mod installed, it is a different story. The game gives a message that the mods are not supported, and then it continues to work without them. I would like this to work in versions too. This will save a lot of time and frustration and also makes it clearer for people who doesn't know you have to get the right version for the right loader.
