Hi there. Here's my code

package net.railowar.src;
import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.World;

public class TileEntityBlockZRail extends TileEntity{
public int mid;

@Override
    public void writeToNBT(NBTTagCompound par1NBTTagCompound)
    {
        super.writeToNBT(par1NBTTagCompound);
        par1NBTTagCompound.setInteger("mid", mid);
    }

@Override
    public void readFromNBT(NBTTagCompound par1NBTTagCompound)
    {
        super.readFromNBT(par1NBTTagCompound);
        this.mid = par1NBTTagCompound.getInteger("mid");
    }
}

But after i save/load, it loses all those mids...

is that the full code?

 

if it is then you cannot save null as an integer

public int mid = 0; makes no result.

Problem solved. That helped
