More Secure Custom Items

Hello everyone! I had a question
currently, we can create ""custom items"" with a crafting shape and a custom name, the current problem is that if someone rename an item with the name of one of the custom items name, it will have the same behavior.
We can do a double check with the meta but it's only working with items that doesn't get damage (food, ores, etc) but for armor and weapons, it doesn't work. Is there any better idea to be sure that a player cannot cheat just by renaming an item ? Ik there is enchants but I try to avoid that.

 

NBT Tags Are Another Way

 

"Custom items" having "custom behaviour" shouldn't rely on an identifier that can be changed by them... like item name as you mentioned. Use nbt tags instead.

 

I keep saying stuff about NBT but never really understood how to use them, can you explain please ?

Yes I know, this is exactly why I made this post, actually, I was hoping that someone mention NBT tags but I wasn't sure that I was correct.

 

It's simple. You set an nbt tag onto an item so you can verify it is a custom item by checking if it has that tag. See how https://github.com/dktapps-pm-pl/AimTP does it.

 

$stick->setNamedTagEntry(new ByteTag(self::AIMSTICK_TAG, 1));
Ah ok I see, it's much easier than I thought. Thank you very much for your help.

 

setting a namedTagEntry on custom crafted items seems to not work.

PHP:

        $i = Item::get(Item::MUSHROOM_STEW, 0, 1);
        $i->setCustomName("Iderula Soup");
        $i->setNamedTagEntry(new StringTag("IDERULA_SOUP", 'aaaaaasdfasdf'));
        $LE = new EnchantmentInstance(Enchantment::getEnchantment(Enchantment::PROTECTION));
        $LE->setLevel(1);
        $i->addEnchantment($LE);
        $CEB = new ShapedRecipe(["AAA"," B ","AAA"],
            ["A"=>Item::get(Item::SPIDER_EYE, 0, 1), "B"=>Item::get(Item::MUSHROOM_STEW,0 , 1)],[$i]);
        $CEB->registerToCraftingManager($this->getServer()->getCraftingManager());

Doing that will make the item to disappear when you try to hold it

 

Crafting inputs don't support any kind of nbt tags (incl custom name, lore, ench)

 

So should I set the NBT on CraftItemEvent if customname = to example Iderula Soup ?

 

sure, it should work

 

This is why I was asking another way to make checks on what is what
