Are blockstates created only once and do they have some kind of index? 1.15.2


Recommended Posts

Creating multiblock system I decided that I will store original blockstate in TEs of blocks of a multiblock because my multiblocks are pretty dynamic and some 3-dimensional array storing their structure wouldn't work. This blockstate will replace corresponding block of the multiblock with itself when the multiblock is dissassembled(some of its blocks are destroyed). But I don't know if each block in the world is unique blockstate or just reference to certain blockstate.

Doing some researches I came across StateContainer that is filled with blockstates in constructor of Block and stored there. This is a proof of blockstates being created only once for each combination of properties.

Do blockstates have fixed indexes? Because I want to store the indexes in unloaded chunks instead of map of properties and values(since O(1) is better than O(n)). "Fixed indexes" means that the same blockstate will have the same index each time game loads.

Why not dig into the World and Chunk classes to find out what happens when you call setBlockState().

They don't have indexes at all.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

The only way to reliably store block states is NBTUtil.writeBlockState, which will serialize a map of properties and their values.

Chunks use IDs to store the states, but these IDs are only valid within that chunk and might change.

    • Goals and Tasks are defined within the flyweight Entity itself whenever it is constructed. I would suggest taking a look at already implemented entities with goals and tasks if you want to implement them yourself.
    • Any mod present on the server (assuming it doesn't have the ignore extension point set) must be present on the client to allow both to connect.
    • Yes, you are passing in an Item instead of a supplier of an item. I would suggest taking another read over the docs.
