              player.addPotionEffect(new PotionEffect(Potion.resistance.getId(), 19, 2));
          }
        }
    }

    @Override

        }

                        }
                    }
                }
            }
        }

                                System.out.println("Something is wrong!");
                            }
                        }
                    }
                }
