@Override
public void install(MissionInit missionInit) {
    // 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  ava  2  s  .co m*/
        if (f.getType() == KeyBinding.class) {

                e.printStackTrace();
            }
        }
    }
    // And then we replace the pointer in the array:
    for (int i = 0; i < settings.keyBindings.length; i++) {
        if (settings.keyBindings[i].getKeyDescription().equals(this.keyDescription)) {
            this.originalBindingIndex = i;

            }
            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:
    Field[] kbfields = KeyBinding.class.getDeclaredFields();
    for (Field f : kbfields) {
        if (f.getType() == KeyBindingMap.class) {

                f.setAccessible(true);
                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);
