[1.12.2] Storing TileEntities of certain type?

[TestingSubject002]

I have a TileEntity class and I need to somehow access all loaded TileEntities of this class. I know about world.loadedTileEntityList, but I have to use my TileEntities constantly and iterating through the list would be very slow.

I have created a list which contains all these TileEntities, but I can't figure out from what function should I add and remove items from the list. Currently, I am using validate() and invalidate() function in TileEntities to do this, but not sure that this is the best solution.

Why do you need this list? What is the effect you want to achieve?

I want to create an entity who patrols all these blocks and I have to save a list of all these blocks positions. I was trying to do this via @SubscribeEvent and in-block-class events, but I have understood that that's not what I need: Blocks are not placed by humans, they are spawning in the world. I thought that creating TileEntities which will add and remove themselves from the list automatically is a good idea.

How far is the furthest between each of those blocks? You could just have your entity search that radius for the tile entity (each chunk has it's own list of tile entities).

This idea is actually cool one, but I have several entities activated at the same time and every entity has it's own blocks to patrol. I understood that using validate and invalidate function is not very bad idea - this model works fine.
