public ForcedChunkManager()

Method Details

init

@Internal
public static void init()

hasForcedChunks

public static boolean hasForcedChunks(net.minecraft.server.level.ServerLevel level)

Checks if a level has any forced chunks. Mainly used for seeing if a level should continue ticking with no players in it.

forceChunk

static <T extends Comparable<? super T>> boolean forceChunk(net.minecraft.server.level.ServerLevel level,
 net.minecraft.resources.ResourceLocation id,
 T owner,
 int chunkX,
 int chunkZ,
 boolean add,
 boolean forceNaturalSpawning,
 Function<net.minecraft.world.level.TicketStorage,ForcedChunkManager.TicketTracker<T>> ticketGetter)

Forces a chunk to be loaded for the given mod with the given "owner".

Parameters:

add - true to force the chunk, false to unforce the chunk.

activateAllDeactivatedTickets

@Internal
public static void activateAllDeactivatedTickets(net.minecraft.server.level.ServerLevel level,
 net.minecraft.world.level.TicketStorage saveData)

Reinstates NeoForge's forced chunks when vanilla initially loads a level and reinstates their forced chunks. This method also will validate all the forced chunks with the registered LoadingValidationCallbacks.

gatherTicketsById

private static <T extends Comparable<? super T>>
Map<net.minecraft.resources.ResourceLocation,Map<T,TicketSet>> gatherTicketsById(ForcedChunkManager.TicketTracker<T> tickets,
 boolean includeLoaded,
 boolean includeDeactivated)

Gathers tickets into an ID filtered map for use in providing all tickets a controller has registered to its LoadingValidationCallback.

gatherTicketsById

private static <T extends Comparable<? super T>>
void gatherTicketsById(it.unimi.dsi.fastutil.longs.Long2ObjectMap<Set<ForcedChunkManager.TicketOwner<T>>> tickets,
 Function<TicketSet,it.unimi.dsi.fastutil.longs.LongSet> typeGetter,
 Map<net.minecraft.resources.ResourceLocation,Map<T,TicketSet>> modSortedOwnedChunks)

Gathers tickets into an ID filtered map for use in providing all tickets a controller has registered to its LoadingValidationCallback.

defineExtraStorageParams

@Internal
public static com.mojang.datafixers.kinds.App<com.mojang.serialization.codecs.RecordCodecBuilder.Mu<net.minecraft.world.level.TicketStorage>,List<ForcedChunkManager.OwnedChunks>> defineExtraStorageParams()

Defines any extra parameters we are adding via a P1#add call

readStoredTickets

@Internal
public static net.minecraft.world.level.TicketStorage readStoredTickets(Function<List<com.mojang.datafixers.util.Pair<net.minecraft.world.level.ChunkPos,net.minecraft.server.level.Ticket>>,net.minecraft.world.level.TicketStorage> vanillaInitializer,
 List<com.mojang.datafixers.util.Pair<net.minecraft.world.level.ChunkPos,net.minecraft.server.level.Ticket>> tickets,
 List<ForcedChunkManager.OwnedChunks> ownedChunks)

Reads any forced chunks we might have previously saved.
