解説

SampleTileEntityCore.java

ブロックの追加方法の解説は1.6のブロック追加

GameRegistry.registerTileEntity(TileEntitySample.class, "TileEntitySample");

TileEntityの登録を行います。 第一引数がTileEntityを継承したクラス、第二引数は他と被らない文字列。

NetworkRegistry.instance().registerGuiHandler(this, new GuiHandler());

Guiを扱うGuiHandlerの登録を登録します。

TileEntitySample.java

@Override
public void readFromNBT(NBTTagCompound par1NBTTagCompound)
{
	super.readFromNBT(par1NBTTagCompound);

	～　中略　～

}

@Override
public void writeToNBT(NBTTagCompound par1NBTTagCompound)
{
	super.writeToNBT(par1NBTTagCompound);

	～　中略　～

}

上記2つのメソッドを使ってTileEntityの情報をNBTに保存します。

public void readToPacket(ByteArrayDataInput data) {
	～　中略　～
}

public void writeToPacket(DataOutputStream dos) {
	～　中略　～
}

@Override
public Packet getDescriptionPacket()
{
	//パケットの取得
	return PacketHandler.getPacket(this);
}

NBTに保存した情報をパケットで飛ばすことができる。
