Curciut problem

[Niklas Ulvinge]

I got a hard problem I don't know how to solve... How do I, with the classes in item.cs, make elecrisity go from a battery throu two cords and back to the battery again. I'll implement the ohm's later... How do the cord know when it should flow elecrisity.:confused: item.cs:

{
//var's
public Item[][] input;

public int y;

    public abstract Strom Output
    {
        get;
    }
    public abstract Point\[\] Snap
    {
        get;
    }

    protected Item(int X, int Y)
    {
        x = X;
        y = Y;
        input = new Item\[1\]\[\];
    }

    //abstract funcs
    public abstract void function();
    public abstract void draw(Graphics g);
    //funcs
    public void addBothInput(int index, int fromIndex, Item Input)
    {
        Input.addInput(fromIndex, this);

        this.addInput(index, Input);
    }
    private void addInput(int index, Item Input)
    {
        index = input.Length & index;

        Item\[\] inp = input\[index\];

        Item\[\] titem;

        if (inp == null)
        {
            titem = new Item\[1\];
        }
        else
            titem = new Item\[inp.Length\];

        for (int i = 0; i < titem.Length - 1; i++)
        {
            titem\[i\] = inp\[i\];
        }
        titem\[titem.Length - 1\] = Input;
        input\[index\] = titem;
    }
    public Strom combinedInput(int index)
    {
        Strom r = 0;
        if (input\[index\] == null)
            return 0;
        else
        {
            for (int i = 0; i < input\[index\].Length; i++)
            {
                r += input\[index\]\[i\].Output\[j\];
            }
            return r;
        }
    }

I could not compile your code because type "Strom" is not defined. Can you also provide this as well?
