[1.7.10] [UNSOLVED] Slots & NBT

[BinaryCPG]

I have 2 Problems:

1) I've got two methods to interact with the slots in my TileEntity:

 

 

public void importMoneyFromInput(EntityPlayer player)
    {
        double val = 0;
        ItemStack input = atmSlots[0];
        if ( input != null )
        {
            if ( input.getItem() instanceof ItemNote )
            {
                val = ((ItemNote) input.getItem()).getValue()*input.stackSize;
            }
            else if ( input.getItem() instanceof ItemCoin )
            {
                val = ((ItemCoin) input.getItem()).getValue()*input.stackSize;
            }
        }

        double lastVal = player.getEntityData().getDouble("bankBalance");
        player.getEntityData().setDouble("bankBalance", val + lastVal);

        atmSlots[0] = null;
        this.onInventoryChanged = true;
    }

    public void exportMoneyFromBuffer (ATMHelper helper, EntityPlayer player)
    {
        helper.updateOutput();

        atmSlots[2] = (ModMoneyHelper.createFullBriefcase(toPutOut_is)).copy();

        double oldVal = player.getEntityData().getDouble("bankBalance");
        double remove = helper.getValueOutput();

        player.getEntityData().setDouble("bankBalance", oldVal-remove);

        helper.reset();
        this.onInventoryChanged = true;
    }

 

(

    this.onInventoryChnaged = true causes this.markDirty()

)

 

 

 

 

The Methods work, but the items in the input-slot don't disappear correctly &

the items in the output-slot don't appear correctly.

 

What did i forgot?

 

2)

I am using the EntityPlayer.getEntityData() to get an double:

 

 

this.bankBalance = player.getEntityData().getDouble("bankBalance");

 

 

& later to set it:

 

 

this.player.getEntityData().setDouble("bankBalance", this.bankBalance);

 

 

It works as long as i don't reload the world. On re-log the var "bankBalance" is 0.

is this because of the development environment (like i can't take screenshots) or did i

miss something?
