卸载对应的函数是Chunk.onChunkUnload
/**

*/
public void onChunkUnload()
{
this.isChunkLoaded = false;
Iterator iterator = this.chunkTileEntityMap.values().iterator();
while (iterator.hasNext())

}
for (int i = 0; i < this.entityLists.length; ++i)
{
this.worldObj.unloadEntities(this.entityLists[i]);
}
MinecraftForge.EVENT_BUS.post(new ChunkEvent.Unload(this));
}
初次生成世界，需要预先加载一部分的块，对应的是Minecraft Server的
protected void initialWorldChunkLoad()
喵on.DimensionManager.getWorld(b0);
BlockPos blockpos = worldserver.getSpawnPoint();
long j = getCurrentTimeMillis();
for (int k = -192; k <= 192 && this.isServerRunning(); k += 16)
{
for (int l = -192; l <= 192 && this.isServerRunning(); l += 16)
{
long i1 = getCurrentTimeMillis();
if (i1 - j > 1000L)
{
this.outputPercentRemaining("Preparing spawn area", i * 100 / 625);
j = i1;
}
++i;
worldserver.theChunkProviderServer.loadChunk(blockpos.getX() + k >> 4, blockpos.getZ() + l >> 4);
}
}
this.clearCurrentTask();
}
对应PlayerInstance中的
public void addPlayer(EntityPlayerMP playerMP)
{
if (this.playersWatchingChunk.contains(playerMP))
{
PlayerManager.pmLogger.debug("Failed to add player. {} already is in chunk {}, {}", new Object[] {playerMP, Integer.valueOf(this.chunkCoords.chunkXPos), Integer.valueOf(this.chunkCoords.chunkZPos)});
}
else
{
if (this.playersWatchingChunk.isEmpty())
{
this.previousWorldTime = PlayerManager.this.theWorldServer.getTotalWorldTime();
}
this.playersWatchingChunk.add(playerMP);
Runnable playerRunnable = null;
if (this.loaded)
{
playerMP.loadedChunks.add(this.chunkCoords);
}
else
{
final EntityPlayerMP tmp = playerMP;
playerRunnable = new Runnable()
{
public void run()
{
tmp.loadedChunks.add(PlayerInstance.this.chunkCoords);
}
};
PlayerManager.this.getMinecraftServer().theChunkProviderServer.loadChunk(this.chunkCoords.chunkXPos, this.chunkCoords.chunkZPos, playerRunnable);
}
this.players.put(playerMP, playerRunnable);
}
Chunk加载对应的回调函数
/**
* Called when this Chunk is loaded by the ChunkProvider
*/
public void onChunkLoad()
{
this.isChunkLoaded = true;
this.worldObj.addTileEntities(this.chunkTileEntityMap.values());
for (int i = 0; i < this.entityLists.length; ++i)
{
Iterator iterator = this.entityLists[i].iterator();
while (iterator.hasNext())
{
Entity entity = (Entity)iterator.next();
entity.onChunkLoad();
喵on.collect.ImmutableList.copyOf(this.entityLists[i]));
}
MinecraftForge.EVENT_BUS.post(new ChunkEvent.Load(this));
}
