What are the ways to do a block update? I have a block that need a change every minecraft day. i know of setTickRandomly() or using ticking tile entity but the first one is not something i have in mind and i really dont like ticking tile entities specially since the block updates so less frequent and there might be not few of them (its something like a regenerating ore). I thought of making some kind of list, subscribe to a world tick event and then when time is right update the list. but can blocks even be updated in unloaded chunks? 

i do have a way using random tick in mind though.

If you need 100% accurate time, you must use a TileEntity.

 

If you don't you can either rely on random ticks (which works fine for things like growing crops, although I've edited that logic to hell, myself).

 

Or you can use world.scheduleBlockUpdate and pass in a sufficiently large number. I don't recommend using 24000 ticks as the "delay" but to try and encode some of the regrowth in the block's metadata (it doesn't need to change visually). You would still want random update ticks in case the scheduled tick never occurs (again, why to use metadata for some of it: if the scheduled tick gets skipped for any reason, you're only out 6000 ticks, not 24000!).

update in the sense of changing the block to another.

 

@Draco18s

thx, ill look more into scheduledBlockUpdate

update: i do think i have to use tile entities since i also want to make it "time-skip" combatible (sleeping).
