Redstone-Activated Custom NBT Tags in Vanilla Minecraft!

Redstone-Activated Custom NBT Tags!

I discovered a fancy dynamic redstone-controlled NBT attribute system for items. You can set it up so that any item containing a certain custom string will have an effect, and you'll never need to touch the redstone again. Let's dive right in!

Check out this totally-completely-original item I made as a demonstration! Under current systems where holding an item gives you bonuses, only this item and items sharing its name would work. But there's hidden NBT data that does that instead!

Here we are at the /give command for the item, where you can see the "bonus" list. Even though this isn't a tag used in vanilla, it still applies the list and all the strings inside of it to the item when it gives it to you, making any items with these strings special.

I have a big clock testing for you holding an item with "bonus:[fire_resist]". Partial list-checking allows this to work for any item with this bonus, even if it has more. If you're holding any item with that bonus string, it activates some redstone.

When I hold the item with the effect, the redstone lights up and activates a very simple scoreboard system. This one causes any mob that attacks me to get set on fire, but it could really be anything.

Yikes! I'm being attacked by this blockhead with only an ordinary diamond sword!

Aha, but when I switch to my special weapon, he gets set on fire!

The "bonus:[fire_resist]" tag the weapon also has gives me fire resistance whenever I'm holding it too.

Here's yet another example: attacking cave spiders is scary because of the poison!

Just equip my completely-original item number 2 and you're immune to poison as well! Again, any item with the special string this item has will provide this buff.

Just to prove that it isn't just for the specific items I've shown you, here's a /give command that gives you a fish with the fire resistance buff.

...and here I am holding it in lava--completely harm-free!
