Tile Entity Data not saving

Recommended Posts

I have a tile entity that updates on right-click with certain items. Whenever I relog, the contents of the jar I'm making is deleted. Any help is appreciated! ;D

 

Code:

 

 

TileEntityJar.java:

package net.mc42.mods.eclipses.tileentities;

import net.mc42.mods.eclipses.mod_Eclipses;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.World;
import net.minecraftforge.fluids.Fluid;
import net.minecraftforge.fluids.FluidRegistry;
import net.minecraftforge.fluids.FluidStack;

public class TileEntityJar extends TileEntity {

private FluidStack contents;
private int amRst;
//private int capacity;

public TileEntityJar(){
	contents = new FluidStack(0, 0);
	amRst = 0;
	//setFluid(mod_Eclipses.lunarEssence);
	//setAmount(2100);
}

public void setFluid(Fluid f){
	contents = new FluidStack(f, amRst);
}

public void setAmount(int i){
	contents.amount = i;
	this.amRst = i;
}

public boolean remove(int mb){
	if(contents.amount >= mb){
		contents.amount -= mb;
		amRst = contents.amount;
		if(contents.amount == 0)
			contents = new FluidStack(0, 0);
		return true;
	}
	return false;
}

public boolean add(int mb){
	if(!(contents.amount + mb > mod_Eclipses.JarCapacity)){
		contents.amount += mb;
		if(contents.amount == 0)
			contents = new FluidStack(0, 0);
		amRst = contents.amount;
		return true;
	}
	return false;
}

public int getPercentFull(){

	//System.out.println((contents.amount/(float)mod_Eclipses.JarCapacity)*(float)100);
	return Math.round((contents.amount/(float)mod_Eclipses.JarCapacity)*(float)100);
}

public boolean hasFluid(Fluid f) {
	// TODO Auto-generated method stub
	return contents.isFluidEqual(new FluidStack(f, 0));
}

@Override
public void writeToNBT(NBTTagCompound par1)
{
   super.writeToNBT(par1);
   NBTTagCompound par2 = new NBTTagCompound();
   par2.setInteger("Amount", contents.amount);
   par2.setInteger("FluID", contents.fluidID);
   System.out.println("Saving... " + contents.amount + " " + contents.fluidID);
   //par2 = contents.writeToNBT(par2);
   par1.setTag("Content", par2);
}

@Override
public void readFromNBT(NBTTagCompound par1)
{
   super.readFromNBT(par1);
   //this.contents.loadFluidStackFromNBT((NBTTagCompound) par1.getTag("Content"));
   NBTTagCompound par2 = new NBTTagCompound();
   par2 = (NBTTagCompound) par1.getTag("Content");
   int amo = par2.getInteger("Amount");
   int id = par2.getInteger("FluID");
   System.out.println("Loaded " + amo + " " + id);
   contents = new FluidStack(id, amo);
   amRst = contents.amount;
}
}

Hi

 

you need to override

onDataPacket and getDescriptionPacket

for the TileEntity.  Otherwise there is no way for the server to tell the client what the contents of the jar are.

 

This example code for 1.6.4 shows you a working example.

https://github.com/mnn/jaffas/blob/59b59f01a1f2f6b21b0dc87e5a15e6761a3f3f19/src/minecraft/monnef/jaffas/food/block/TileEntityPie.java#L117

 

Should still work in 1.7 with some tweaking (i.e. Packet name change)

Hi

 

The vanilla and forge code show the way forward....

 

TileEntity::
    /**
     * Called when you receive a TileEntityData packet for the location this
     * TileEntity is currently in. On the client, the NetworkManager will always
     * be the remote server. On the server, it will be whomever is responsible for
     * sending the packet.
     *
     * @param net The NetworkManager the packet originated from
     * @param pkt The data packet
     */
    public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity pkt)
    {
// your code here
    }

 

Similarly getDescriptionPacket should return the same S35 packet.

Alright thats what I came up with:

    
@Override
public Packet getDescriptionPacket()
    {
    	NBTTagCompound nbt = new NBTTagCompound();
	nbt.setInteger("meta", this.blockMetadata);
        return new S35PacketUpdateTileEntity(this.xCoord, this.yCoord, this.zCoord, 1, nbt);
    }
    
@Override
    public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity pkt)
    {
    	super.onDataPacket(net, pkt);
    	this.blockMetadata = pkt.func_148857_g().getInteger("meta");
    }

in my TileEntity

and in the renderer:

	@Override
public void renderTileEntityAt(TileEntity entity, double x, double y, double z, float f) {
//....
	int m = entity.blockMetadata;
//....

But still not working :(

No no no no.

 

Don't send your metadata in the packet at all!  Block metadata is already synced between client and server.

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.
