Я, создавая механизмы для своего мода, столкнулся с проблемой корявого отображения количества энергии (записывается в NBT тайла) в клиентском GUI (GUI, как и элемент отображения используют CoFHLib). Синхронизируется это всё дело только при обновлении чанка. Ниже прилагаю нынешний код базового тайла, который наследуют все остальные тайлы и GUI, в котором элемент добавляется.
Java:
public abstract class BasicTileEntity extends TileEntity {
public abstract void readCustomNBT(NBTTagCompound tags);
public abstract void writeCustomNBT(NBTTagCompound tags);
@Override
public void readFromNBT(NBTTagCompound nbt) {
super.readFromNBT(nbt);
readCustomNBT(nbt);
}
@Override
public void writeToNBT(NBTTagCompound nbt) {
super.writeToNBT(nbt);
writeCustomNBT(nbt);
}
@Override
public S35PacketUpdateTileEntity getDescriptionPacket() {
NBTTagCompound tagCompound = new NBTTagCompound();
this.writeToNBT(tagCompound);
S35PacketUpdateTileEntity pack = new S35PacketUpdateTileEntity(xCoord, yCoord, zCoord, 0, tagCompound);
return pack;
}
@Override
public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity pkt) {
this.readFromNBT(pkt.func_148857_g());
}
}
Java:
public class TileEntityAssembler extends BasicTileEntity implements IEnergyHandler, IInventory{
private ItemStack[] items = new ItemStack[10];
public EnergyStorage EstorageAssembler = new EnergyStorage(131072, 16384, 16384);
public TileEntityAssembler() {
}
@Override
public void readCustomNBT(NBTTagCompound nbt)
{
EstorageAssembler.readFromNBT(nbt);
NBTTagList list = nbt.getTagList("Items", Constants.NBT.TAG_COMPOUND);
items = new ItemStack[getSizeInventory()];
for (int i = 0; i < list.tagCount(); ++i) { NBTTagCompound comp = list.getCompoundTagAt(i); int j = comp.getByte("Slot") & 255; if (j >= 0 && j < items.length)
{
items[j] = ItemStack.loadItemStackFromNBT(comp);
}
}
}
@Override
public void writeCustomNBT(NBTTagCompound nbt)
{
EstorageAssembler.writeToNBT(nbt);
NBTTagList list = new NBTTagList();
for (int i = 0; i < items.length; ++i)
{
if (items[i] != null)
{
NBTTagCompound comp = new NBTTagCompound();
comp.setByte("Slot", (byte)i);
items[i].writeToNBT(comp);
list.appendTag(comp);
}
}
nbt.setTag("Items", list);
