My tileenetity is not saving its items. I can place items in the slots but once I leave and save the world and go back in the items are deleted.

 

TileEntity:

package com.waffle.to.tileentity;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.inventory.IInventory;
import net.minecraft.item.ItemStack;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.nbt.NBTTagList;

import net.minecraft.util.text.ITextComponent;

import java.util.ArrayList;

public class TOTileEntity extends TileEntity implements IInventory{

    private ItemStack[] stacks = new ItemStack[9];

    private boolean aBoolean;
    private byte aByte;
    private short aShort;
    private int anInt;
    private long aLong;

    private byte[] aByteArray;
    private int[] anIntArray;



    private ItemStack anItemStack;

    private ArrayList aList = new ArrayList();

  private ItemStack[] inventory;
  private String customName;

    public TOTileEntity(){
        this.inventory = new ItemStack[this.getSizeInventory()];
    }

        return this.customName;
    }

    public void setCustomName(String customName){
        this.customName = customName;
    }

    @Override

        return this.hasCustomName() ? this.customName : "container.to_tile_entity";
    }

                } else {

                    this.setInventorySlotContents(index, this.getStackInSlot(index));
                }

                this.markDirty();

There is server and there is client.

 

Without even looking at code:

 

1. Do you actually know that NBT is not saving/loading? Meaning - have you printed it in those methods, is it empty?

2. If yes - Fix your NBT code, if no - you are out of sync. Why? Becaouse you don't send description packet.

You need the getDescriptionPacket and onDataPacket methods for it to save.

 

1st one should return TE data packed in Packet (server), 2nd one should decrypt it. Look into vanilla.

1.7.10 is no longer supported by forge, you are on your own.

Ok so I added 2 lines to print both the reading and writing and its printing both but not sure if its actually doing it.

 

[00:27:16] [server thread/INFO]: [com.waffle.to.tileentity.TOTileEntity:writeToNBT:208]: WRITING NBT DATA

[00:27:10] [server thread/INFO]: [com.waffle.to.tileentity.TOTileEntity:readFromNBT:185]: READING NBT DATA

I think I implemented the getDescriptionPacket and onDataPacket but nothing happened the same thing is still happening.

 

  @Override
    public Packet getDescriptionPacket(){
        NBTTagCompound data = new NBTTagCompound();
        writeToNBT(data);
        return new SPacketUpdateTileEntity(this.pos, 1, data);
    }

    @Override
    public void onDataPacket(NetworkManager net, SPacketUpdateTileEntity pkt){
        readFromNBT(pkt.getNbtCompound());
        worldObj.markBlockRangeForRenderUpdate(this.pos, this.pos);
    }
