PrepareItemCraftEvent - want to craft item, with named and lored ingredients

Hi!

First, I wil show my code:

Code:java

@EventHandler(priority = EventPriority.NORMAL, ignoreCancelled = true)
      public void onPrepareItemCraft(PrepareItemCraftEvent event)
        {
                ItemStack[] inv = event.getInventory().getMatrix();
 
                for(ItemStack ingr : inv){
                    if(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();
                    //List<String> lore = ingr_meta.getLore();
                    if(ingr_name != "Swiety kamien"){
                            event.getInventory().setResult(new ItemStack(Material.AIR));
                            return;
                    }
 
                }
                }
        }

So... I have new craft shape (4x sponge -> blaze rod with name), but i want to make blaze rod with name ONLY with named and lored 4x sponge (it drops from mobs). Code works that: if in crafting table is sponge, but with no-name, result will be stone. But it doesn't work ;c

No errors, but when I insert 4x sponge with name "Swiety kamien", in result is air
Sorry for my bad english, but i think, that you can read this ;D

I had the same problem as you did, and I managed to get it to work, here you go

Code:java

 
@EventHandler(priority=EventPriority.HIGH)
public void customCrafting(PrepareItemCraftEvent e){
if( e.getInventory().getResult().getType() == Material.ANVIL){
for( int i = 0 ; i < e.getInventory().getSize() ; i++ ){
final ItemStack item = e.getInventory().getItem(i);
if(e.getInventory().getItem(i) != null){
if(item.getType() == Material.GHAST_TEAR){
if(item.getItemMeta().getDisplayName().contains("Puppies")){
e.getInventory().setResult(new ItemStack(Material.LEATHER, 1));
}
}
}
}
}
}
 

This is what it does: If the result of the crafting recipe is an anvil, it will check the recipe for a "GHAST_TEAR" (which is part of the recipe) and if it has the name "Puppies" then it will change the recipe result into LEATHER.

I hope you understand and make use out of this
