Oh ok. Will look into it. Thank you.

I would like it to spread to multiple chunks. Source will be some sort of machine that does this. Would it be better to map out NO_AIR around the source and then setting it to clear air from no air directly from Source(not from CleanAir) and doing that every 10 ticks. Also there can be a possibility that two sources are in one chunk.

So I would like to have infestation(spreading) with capacity. The way it would work is by having a source block(or entity is also fine) that is going to spread blocks. Each of those blocks will implement spread more blocks. All blocks will stop spreading when capacity in source block is equal to zero. Ways I tried: Using non-Static variable in every spreading block that is linked to the Source block - ended up finding out that I can't do that Using Blockstates(Source will have capacity, and every new block will have its coordinates saved in its own blockstate, way I changed the capacity is just by replacing source blocks with a new block), problem here is that number of coordinates it to big to be handled by blockstates so java runs out of memory that way. For the first try I have no code. NO_AIR is a register for a block that this infesting block can replace. CLEAR_AIR is a register for the clear air. For the second one here it is: CleanAir block: package; //has a proper package name import net.minecraft.core.BlockPos; import net.minecraft.server.level.ServerLevel; import net.minecraft.world.level.Level;
