[1.7.10][Unsolved]TileEntity saving variables


Enginecrafter

Recommended Posts

I have a block, that have TileEntity. When I "re-log" to the world, all my Blocks-with-tileEntity are rotated to 0(South)

Can you help me with fixing it?

Likely you need these two functions:

 

	@Override
    public void readFromNBT(NBTTagCompound tc) {
        super.readFromNBT(tc);
        //load your variables
    }

    @Override
    public void writeToNBT(NBTTagCompound tc) {
        super.writeToNBT(tc);
        //save your variables
    }

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Oh, sorry.

I forgot to place my code inside of my post.

 

Here is it:

 

 

package com.ec.tileentity;

import java.util.Random;

import com.ec.blocks.MyBlocks;
import com.ec.lib.MainLib;

import net.minecraft.block.Block;
import net.minecraft.entity.item.EntityItem;
import net.minecraft.init.Blocks;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.World;

public class TileEntityExcavator extends TileEntity{

public int direction = 0;
public boolean active = false;

@Override
public void writeToNBT(NBTTagCompound tag)
{
	super.writeToNBT(tag);
	tag.setInteger("direction", direction);
	tag.setBoolean("active", active);
}

@Override
public void readFromNBT(NBTTagCompound tag)
{
	super.readFromNBT(tag);
	this.direction = tag.getInteger("direction");
	this.active = tag.getBoolean("active");
}

@Override
public void updateEntity()
{
	int[] BTD = new int[3];

	switch(this.direction)
	{
	case 0:
		//South
		BTD[0] = xCoord;
		BTD[1] = yCoord;
		BTD[2] = zCoord + 1;
		break;
	case 1:
		//West
		BTD[0] = xCoord - 1;
		BTD[1] = yCoord;
		BTD[2] = zCoord;
		break;
	case 2:
		//North
		BTD[0] = xCoord;
		BTD[1] = yCoord;
		BTD[2] = zCoord - 1;
		break;
	case 3:
		//East
		BTD[0] = xCoord + 1;
		BTD[1] = yCoord;
		BTD[2] = zCoord;
		break;
	}



	if(!worldObj.isRemote)
	{
		float[] floatLocation = MainLib.centerBlock(xCoord, yCoord, zCoord);
		double x = (double) floatLocation[0];
		double y = (double) floatLocation[1] + 1;
		double z = (double) floatLocation[2];

		Block destroyedBlock = worldObj.getBlock(BTD[0], BTD[1], BTD[2]);

		if(worldObj.getBlockPowerInput(xCoord, yCoord, zCoord) > 0)
		{
			if(destroyedBlock != Blocks.air)
			{
				worldObj.setBlockToAir(BTD[0], BTD[1], BTD[2]);
				worldObj.spawnEntityInWorld(new EntityItem(worldObj, x, y + 1, z, new ItemStack(Item.getItemFromBlock(destroyedBlock))));
			}
		}
	}
}
}

 

 

 

And, how can I notify this block of neighbour change (Make this block update or update its texture)?

You need these two functions in your class:

public Packet getDescriptionPacket() {

NBTTagCompound tag = new NBTTagCompound();
writeToNBT(tag);
return new S35PacketUpdateTileEntity(this.xCoord, this.yCoord, this.zCoord, 1, tag);

}

public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity packet) {

readFromNBT(packet.func_148857_g());

}

 

This will send data updates to the client when the chunk with the TE is loaded. It will work on singleplayer and multiplayer.

I explain, why I think they are not saved. But I am not sure, because of this:

1. I place one block (from my mod:excavator) and when I placed it, it created tileentity and writes to it a INT direction. Then, is writed in code: every tick check if is powered by redstone. If true, set BOOLEAN active to true. This boolean is used only for texture. This block will check every tick, if behind it is any block, if true, then drops it on this(machine) block.

2. I leave(exit from) the world and again join (play) the world.

3. I looked at the blocks. All are rotated to the default direction-South(0).

When I place a block next to it's back texture side, and power it with redstone, nothing happens, but when I place a block at side, where back texture side was rototated before, it destroy the block and drop it.

And about the block update.

I made this block react to redstone-when I turn the power ON, the block must change it's texture. But nothing happens while I place or destroy block next to it. I wanted when is redstone on, update or notify block.

On the server side, the

getDescriptionPacket

method is called, and that method returns a

S35PacketUpdateTileEntity

containing and

NBTTagCompound

containing the data you have written to it. Then it sends the packet to the client side and it calls the

onDataPacket

with the packet returned from the

getDescriptionPacket

, in which you read all the data from the

NBTTagCompound

in the packet.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

Well, I understood. :D

Sorry, I am going off topic...

Do you know about good tutorial for leanring TileEntities, that implement IInventory?

I never made them, but I want to learn how-to them.
