@Override

    // Attempt to find the keybinding that matches the description we were given,
    // and replace it with our own KeyHook object:
    GameSettings settings = Minecraft.getMinecraft().gameSettings;
    boolean createdHook = false;
    // GameSettings contains both a field for each KeyBinding (eg keyBindAttack), and an array of KeyBindings with a pointer to
    // each field. We want to make sure we replace both pointers, otherwise Minecraft will end up using our object for some things, and
    // the original object for others.
    // So we need to use reflection to replace the field:
    Field[] fields = GameSettings.class.getFields();
    for (int i = 0; i < fields.length; i++) {
        Field f = fields[i];//from   w  w w . j  a v  a2s  .c o  m

            }
            settings.keyBindsHotbar[i] = this.keyHook;
        }
    }
    // Newer versions of MC have changed the way they map from key value to KeyBinding, so we
    // *also* need to fiddle with the static KeyBinding HASH map:

    for (Field f : kbfields) {
        if (f.getType() == KeyBindingMap.class) {

                kbp = (KeyBindingMap) (f.get(null));
                // Our new keybinding should already have been added;
                // just need to remove the original one.
                while (kbp.lookupAll(this.keyHook.getKeyCode()).size() > 1)
                    kbp.removeKey(this.originalBinding);
