[Problem] Malutka poprawka w moim pluginie :)

[karer]

Siemka! Oto mój kod:

@EventHandler(priority = EventPriority.NORMAL, ignoreCancelled = true)
	  public void onPrepareItemCraft(PrepareItemCraftEvent event)
	    {
				ItemStack[] inv = event.getInventory().getMatrix();
				List<String> valid = new ArrayList<String>();
				
				
				boolean petla = true;
				for(ItemStack ingr : inv){
					if(petla==true){
					if(ingr.getType().isBlock() == true && ingr.getType() == Material.SPONGE)
					{
						//ingr to itemstack, mozemy na nim operowac
						ItemMeta ingr_meta = ingr.getItemMeta();
						String ingr_name = ingr_meta.getDisplayName();
						Player plr = (Player) event.getView().getPlayer();
						
						boolean lorek = false;
						if(ingr_meta.hasLore()==true && ingr_meta.hasDisplayName()==true){
							plr.sendMessage(ingr_name);
							for(String dupa : ingr_meta.getLore()){
								if(dupa.contains("Avalonu")){
									lorek = true;
								}
							}
							
							boolean named = ingr_name.contains("kamien");
		
							
							if(lorek == false || named == false){
								event.getInventory().setResult(new ItemStack(Material.AIR));
								petla = false;
								return;
							}else{
								//gitara
								valid.add("true");
							}
						
						}else{
							petla = false;
							event.getInventory().setResult(new ItemStack(Material.AIR));
							return;
						}
					
					}
				}
				}
				//sprawdzamy calkowita poprawnosc
				for(String val : valid){
					if(val=="true"){
						
					}else{
						event.getInventory().setResult(new ItemStack(Material.AIR));
						return;
					}
				}
	    }

Skrypt jest dosyc prosty - mam nowego crafta, na blaze rod:

###

#!#

!!!

 

# - puste miejsce

! - gabka

 

chodzi o to, aby enchant byl mozliwy tylko wtedy, gdy gabka ma w nazie "kamien", a lore gabki "Avalonu"

 

Niby wszystko dziala dobrze, ale jezeli robie jakis inny enchant, to konsola zawsze pluje:
