Chunk Events

dev.architectury.event.events.common.ChunkEvent

Fires when a chunk's data is saved or loaded, letting you attach and read your own persistent data. Both are notifications.

Events

Event	Listener method	When
SAVE_DATA	save(ChunkAccess, ServerLevel, SerializableChunkData)	Just before a chunk's data is written.
LOAD_DATA	load(ChunkAccess, ServerLevel, SerializableChunkData)	Just before a chunk's data is read.

On SAVE_DATA, write your own values into the provided data so they're persisted alongside the chunk; on LOAD_DATA, read them back. The ServerLevel passed to load may be null.

Example

ChunkEvent.SAVE_DATA.register((chunk, level, data) -> {
    // store your mod's per-chunk data into `data`
});

ChunkEvent.LOAD_DATA.register((chunk, level, data) -> {
    // read your mod's per-chunk data back from `data`
});
