[1.7.10] How to stop tile entity from reading nbt data on first place

[Silly511]

I have a tile entity that stores energy from a custom energy system I made, but the problem is that when I place down the energy storage block next to another energy storage block, the other energy storage block outputs all of its energy to the one I just placed down. Thats what it is supposed to do, and it does that but the problem is that it outputs all of its energy to the energy storage block I just placed down, before the tile entity initializes, so it outputs the power then that power gets deleted because it reads the nbt data first then writes it. So basically when ever I place a energy storage block next to another one, all the power in the first gets deleted. So, how do I stop a tile entity from reading nbt data when you first place the block?

[Silly511]

Then why is this happening? Here is my code:

 

Main tile entity:

package net.sparklepopprograms.enchantedaura.tileentitys;

import net.minecraft.tileentity.TileEntity;
import net.sparklepopprograms.core.api.energy.BaseEnergyStorageBlock;
import net.sparklepopprograms.core.api.energy.IAuraUser;
import net.sparklepopprograms.core.util.PositionInWorld;
import net.sparklepopprograms.core.util.WorldHelper;

public class TileAuraBuffer extends BaseEnergyStorageBlock {

public TileAuraBuffer() {
	super();
	this.setCapacity(35000);
}

@Override
public void updateEntity() {
	PositionInWorld[] output = WorldHelper.getListOfPositionsAroundBlock(xCoord, yCoord, zCoord);
	int meta = worldObj.getBlockMetadata(xCoord, yCoord, zCoord);

	TileEntity tile = worldObj.getTileEntity(output[meta].getX(), output[meta].getY(), output[meta].getZ());

	if (tile instanceof IAuraUser) {
		this.extractAura(((BaseEnergyStorageBlock)tile).receiveAura(this.getStoredAura(), false), false);
	}
}

}

 

BaseEnergyStorageBlock:

 

package net.sparklepopprograms.core.api.energy;

import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.network.NetworkManager;
import net.minecraft.network.Packet;
import net.minecraft.network.play.server.S35PacketUpdateTileEntity;
import net.minecraft.tileentity.TileEntity;

public class BaseEnergyStorageBlock extends TileEntity implements IAuraUser {

long energy;
long capacity;

public void readFromNBT(NBTTagCompound var1) {
    super.readFromNBT(var1);
    energy = var1.getLong("AuraStorage");
  }

public void writeToNBT(NBTTagCompound var1) {
    super.writeToNBT(var1);
    var1.setLong("AuraStorage", energy);
  }

public void setCapacity(long capacity) {

	this.capacity = capacity;

	if (energy > capacity) {
		energy = capacity;
	}
}

public long receiveAura(long maxReceive, boolean simulate) {

	long energyReceived = Math.min(capacity - energy, maxReceive);

	if (!simulate) {
		energy += energyReceived;
	}

	return energyReceived;
}

public long extractAura(long maxExtract, boolean simulate) {

	long energyExtracted = Math.min(energy, maxExtract);

	if (!simulate) {
		energy -= energyExtracted;
	}

	return energyExtracted;
}

public void modifyEnergyStored(int energy) {

	this.energy += energy;

	if (this.energy > capacity) {
		this.energy = capacity;
	} else if (this.energy < 0) {
		this.energy = 0;
	}
}

public long getStoredAura() {

	return energy;
}

public long getMaxStoredAura() {

	return capacity;
}

@Override
public Packet getDescriptionPacket() {
        NBTTagCompound nbttagcompound = new NBTTagCompound();
        this.writeToNBT(nbttagcompound);
        return new S35PacketUpdateTileEntity(this.xCoord, this.yCoord, this.zCoord, 3, nbttagcompound);
    }

@Override
public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity pkt) {
	this.readFromNBT(pkt.func_148857_g());
}

}

Everything now only runs on the server side, the problem is still there.

[Silly511]

I have Waila integration for my energy system. When I place the storage block down, it says it has the correct amount of energy, but then it jumps to zero.

[BusyBeever]

Well the point is that it might be that the energy value isnt synced, so waila tells you that the energy is zero (on ur side, client) but on server side it is correct and simply not synchronized with client

[Draco18s]

How do I synchronize it?

 

Packets.

[Silly511]

I am using packets. It does sync. First it shows the correct value, then it turns to zero, then it starts counting up and works fine after that. It's the initial transfer that does not work, but after that it works fine.
