Tracking Chocolate bars crushed per/h?

[AsBakedAsCake 202]

Looking for string to track this. Made my first chocolate crusher and I'd like to add this in. If anyone can help I'd appreciate it, I literally can't figure out how to track it.

 

Thanks for any help dudes.

public class ItemTracker extends AbstractScript implements InventoryListener {


    private int counter;

    private final int CHOCLATE_DUST_ID = -1;


    @Override

    public int onLoop() {

        return 0;

    }


    @Override

    public void onPaint(Graphics g) {

        g.drawString("Crushed: " + counter, 15, 30);

    }


    @Override

    public void onItemChange(Item[] items) {

        for (Item item : items) {

            if (item.getID() == CHOCLATE_DUST_ID) {

                counter += item.getAmount();

            }

        }

    }

}
