Class CubeSplitTickSet

java.lang.Object

All Implemented Interfaces:

public class CubeSplitTickSet
extends java.lang.Object
implements java.util.Set<net.minecraft.world.NextTickListEntry>

When saving chunks, Minecraft needs to filter all of the scheduled ticks by the chunk being saved. Normally this is not a big issue, as there aren't a lot of scheduled ticks. But in some cases (especially on fresh world in the first seconds) there are hundreds of thousands of scheduled ticks. For vanilla-sized chunks, this filtering is still acceptably fast (even if can still cause noticeable delay when saving chunks). For 16x16x16 chunks, it can take minutes to save the whole world. Instead of completely rewriting vanilla handling of scheduled ticks to store them in cubes and also changing the behavior (vanilla "throttles" about of updates per tick), this class implements a collection that keeps track of which entries belong to which cube. This also has the benefit that scheduled ticks are still stored in the same fields, so existing code that relies on it will just work.
