So i am making a power system where everything extends a base tile entity class and i cant get the energy parameter to save properly after i exit the world and reload it.

 

Here is the base tile entity class

package libraCraft.blocks.tileEntity;

import java.io.ByteArrayOutputStream;
import java.io.DataOutputStream;
import java.util.Random;

import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;
import libraCraft.blocks.LCBlockEnergy;
import net.minecraft.entity.player.EntityPlayerMP;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.network.NetworkManager;
import net.minecraft.network.Packet;
import net.minecraft.network.PacketBuffer;
import net.minecraft.network.play.server.S35PacketUpdateTileEntity;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.World;
import net.minecraft.world.chunk.Chunk;

public class LCBlockEnergyTE extends TileEntity {
public int energy;
public int packetAmount;
public int maxEnergy;
public int fuel;
public boolean canSend = false;
public boolean canReceive = false;

@Override
public void writeToNBT(NBTTagCompound nbt) {
	System.out.println("WriteToNBT");
	nbt.setInteger("energy", energy);
	nbt.setInteger("packetAmount", packetAmount);
	nbt.setInteger("maxEnergy", maxEnergy);
	nbt.setInteger("fuel", fuel);
	nbt.setBoolean("canSend", canSend);
	nbt.setBoolean("canReceive", canReceive);
}

@Override
public void readFromNBT(NBTTagCompound nbt) {
	System.out.println("ReadFromNBT");
	energy = nbt.getInteger("energy");
	packetAmount = nbt.getInteger("packetAmount");
	maxEnergy = nbt.getInteger("maxEnergy");
	fuel = nbt.getInteger("fuel");
	canSend = nbt.getBoolean("canSend");
	canReceive = nbt.getBoolean("canReceive");
}

@Override
public void updateEntity() {
	BalanceEnergy();
}

public void BalanceEnergy() {
	int x = xCoord;
	int y = yCoord;
	int z = zCoord;
	Random random = new Random();
	World world = worldObj;
	int range = 5;
	for (int  = -range;  <= range; ++) {
		for (int yD = -range; yD <= range; yD++) {
			for (int zD = -range; zD <= range; zD++) {
				if ( != 0 || yD != 0 || zD != 0) {
					if (world.getBlock(x + , y + yD, z + zD) instanceof LCBlockEnergy) {
						if ((LCBlockEnergyTE) world.getTileEntity(x + , y
								+ yD, z + zD) instanceof LCBlockEnergyTE) {
							LCBlockEnergyTE tile2 = (LCBlockEnergyTE) world
									.getTileEntity(x + , y + yD, z + zD);
							LCBlockEnergyTE tile1 = (LCBlockEnergyTE) world
									.getTileEntity(x, y, z);
							if (tile1.canSend == true
									&& tile2.canReceive == true) {
								if (tile1.energy >= tile1.packetAmount
										&& tile2.energy <= tile2.maxEnergy
										&& tile1.energy > tile2.energy
										&& tile1.energy - tile2.energy > tile1.packetAmount) {
									tile1.energy = tile1.energy
											- tile1.packetAmount;
									tile2.energy = tile2.energy
											+ tile1.packetAmount;
									world.markBlockForUpdate(x, y, z);
									SpawnParticles(world, tile2.xCoord,
											tile2.yCoord, tile2.zCoord, ,
											yD, zD);

								}
							}
						}
					}
				}
			}
		}
	}
}

private void SpawnParticles(World world, int xCoord, int yCoord,
		int zCoord, int , int yD, int zD) {
	Random random = new Random();
	for (int lk = 0; lk < 40; lk++) {
		world.spawnParticle("portal", (double) xCoord + 0.5D,
				(double) yCoord + 1.0D, (double) zCoord + 0.5D,
				(double) ((float) (-) + random.nextFloat()) - 0.5D,
				(double) ((float) (-yD) - random.nextFloat() - 0.5F),
				(double) ((float) (-zD) + random.nextFloat()) - 0.5D);
	}
}

@Override
public Packet getDescriptionPacket() {
	NBTTagCompound tag = new NBTTagCompound();
	System.out.println("GetDescriptionPacket");
	writeToNBT(tag);
	return new S35PacketUpdateTileEntity(xCoord, yCoord, zCoord, -999, tag);
}

@Override
public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity pkt) {
	System.out.println("OnDataPacket");
	super.onDataPacket(net, pkt);
	readFromNBT(pkt.func_148857_g());
}
}

 

one of the blocks extending this tile entity

package libraCraft.blocks.tileEntity;

import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.World;

public class TEEnergyCube extends LCBlockEnergyTE {
public TEEnergyCube() {
		this.maxEnergy = 3000;
		this.packetAmount = 1;
		this.canReceive = true;
		this.canSend = true;
	}
}

@SidedProxy(clientSide = Ref.CLIENT_PROXY, serverSide = Ref.SERVER_PROXY)

	ConfigHandler.init(event.getSuggestedConfigurationFile());

I add some energy to the to the tile entity with a debug item and I have it print the energy amount, lets say it has 50 energy after clicking it. after exiting and reloading the world it is back at 0. anyone have any ideas? the rest of the source is available here: https://github.com/eliteznightmare/LibraCraft

 

 

in readFromNBT and writeToNBT you must call the super method. It saves the most important information i.e. the id and x, y, z coords

just added those lines to read and write NBT, yet the issue still persists.

Hi

 

I am a newbie and I just started to play around with the whole TE system. I'm either not sure what you're line there exactely does:

world.markBlockForUpdate(x, y, z);

 

If I want to get my TE's nbt stored to disk, I use

markDirty()

From the (vanilla) TE class.

 

May this helps and you're able to set your issue to null;)

 

Sincerely -pick

mark dirty didn't work either, markBlockForUpdate() is the same as markDirty() i believe, but dont quote me on that
