[1.12.2] Use custom entity to mark position of blocks


DavidM

Recommended Posts

I am creating a "wireless power generator" that automatically sends power to my machines in a 35*35*35 area.

However, if I iterate through the 35*35*35 area every tick to find all nearby machines, that would probably result in performance issues.

Therefore, I was wondering if it is possible to create a custom entity whenever one of my machines is placed, and use World#getEntitiesInAABB to get all nearby machines to send power to.

Is this possible? If yes, what are the drawbacks (if any) of this method?

1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.

2. Always post your code.

3. Never copy and paste code. You won't learn anything from doing that.

Using a PooledMutableBlockPos and scanning 35x35x35 isn’t too expensive, but a better way would be to iterate Chunk#loadedTileEntityList
