Couldn't you have the function that summons the fireball also give you another book? It'd sometimes be placed in a different inventory slot which is annoying, but it might be usable.

The fact that it is consumable is so great, it replaces using snowballs which had to use a ticking command or ender eyes which only worked in the overworld

It's right-click AND consumable? This is incredible, you can make magic spells come in bulk with one craft, and make healing or buffing spells! It's a drawback, but it opens the door to new features!

I think map-makers, specifically rpg ones might use this to make some sort of magic system. Dunno great vid

me when i use a datapack that unlocks every recipe in the game upon joining a world, causing every knowledge book effect to trigger at the same time:

Another rightclick detection u can use in 1.20.5 is giving your item the new food component set the eating time very very high and just create an item_used advancement... cons: Player could eat the item when holding right click for a week or so... You will be slowed down...

I will for sure use this knowledge, thank you!

you could just add back the items to the inventory, which still makes it a hack, but is way more optimized than a tick function

This is crazy, I saw your next video first and the speed of how fast we’re learning new things with components is wild. Rlly feels like this update is on the level of Command Block Minecarts

"I cast thunderspell"

Great vid, just a quick tip. You can set a noise gate and noise impression in OBS in the microphone filters to remove the noise from your videos.

they should have made it so knowledge books can grant any advancement, considering that recipes are normally granted by advancements anyway, that way you wouldn't need the recipe.

this is a lot of cool stuff, it's really cool to see into your mind and your reasoning towards utilizing the recipe books, good stuff!

Great Vid! One other thing: an ender eye can be used with an advancement for a similar effect. Only drawback is compatibility with survival worlds; otherwise, in 'No structure generation' worlds, it works great.

imagining a spell system where on use it reverts to regular book halfway between potions and enchantments

This is actually exactly what I've been trying to accomplish, I have consumable books that increase a certain stat for the player and this achieves it with way fewer commands running. Awesome!

honestly thanks for this video i started using knowledge books for consumables now

Dude you're actually a genius i gotta do smth with this

I have been using Knowledge books for a couple years now, and they are great. I did not however know about the recipe detection. I just used a scoreboard for tracking uses. So thanks.

Quite a eazy fix for using it, is having the fuction use /item to replace your mainhand back with the book. Only issue is detecting if you used it in your offhand. So not a perfect solution.

ill sub bc u deserve more subs, also i love the white noise. idk if its on purpose but i love it

this is my first video from you, but PLEASE do me a favor and record your audio in Audacity, and use the noise removal tool if you NEED to have your mic volume loud. The white noise is distracting

Might be a good option for custom boss/enemy spawning.

I ran into this a couple versions ago. You can get around the consumable issue by placing the item back into the player’s empty hand. There is then the issue of then using it in an offhand, but I’m sure there’s ways to detect it.

I tinkered with this rclick detection back some years ago, however since I didn't see anyone else using it I just never used it again. Damn

Well, in most custom maps I've seen items are usually stuck to certain slots anyways

I think it would be wuite fun if they gave you an option later for a "search recipe survival" where you have one book and have to expend some resources to use them making the search books. I think it would be quite funner. Or, if not that, make the player start with the craftings of processed wood, crafting table, paper and the book or something like that. Minecraft doesn't really has the factor gameplay, and i think it would make the game more fun to play, but being an optional for those who want to play for the long-run maybe making use of the new biome blocks. Idk.

I do know a slightly complicated way of making the book never run out.

This is actually really cool!

I find it interesting that mods have had NBT data in recipes since like 1.10 and vanilla is only now getting the ability to have NBT data in recipes

Mojang should add NBT similar to the unbreaking tag but it makes consumable items not get consumed

Make it into a nonstackable item and then when you right click have it do /item to put the book back in your hand.

before watching this video, i was actually contemplating using bad luck potions and predicate effect duration detection, to unlock recipes for my limited crafting datapack. But well you know. apparently there are already recipe items. Now I swear I knew they were used for custom crafting, it just never occured to me, that they had an intended purpose too. (But recipe potions still sound cooler)

Advancement aren't instant, they don't trigger at the exact time when you click, they also get tested once per tick but not at the same time IN the tick. (I don't know the order by heart so I'll totaly make that order up) For example, you can have the recipe unlocked advencement kind, then the recipe crafted, then the tick advancement, then the functions, and then the player_interacted_with_entity The reason why it can be useful is that all advencement aren't tested every tick. For example, if you haven't unlocked any recipe this tick, then none of the "recipe_unlocked" will be tested

Interaction entities also work but they kinda bad bc they disallow the player from interacting with the world bc they block it

The part about it triggering instantly isnt correct. While its true that advancements trigger at any point in a tick, "player used item" is only checked for once per tick. Also, iirc, unless you are doing something with subticks, it wont make a difference like in your example with /summon, since that wont be rendered to your screen or be interactable until the next tick anyway

make a full magic datapack

As an avid modded player who has a jei addiction Yeahh knowledge book is pretty useful Also its a lovely progression gate in certain modpacks

Can you modify the max stack size from 1 to 2 and set the stack size to 2 before the item is removed? This could allow for reusable (and very spammabke spells that don't need to worry about moving into a different inventory slot.

Another way i think minecraft could make knowledge books slightly less useless is to actually have knowledge books with random or not so random recipes spawn in chests because i swear i still have to look up how to craft a blast furnace in google because i have no idea what its made from and i dont have the items for it so i never unlocked the recipe. It would be a way for new players to unlock recipes in the early game they would otherwise never know how to make... Just a thought

It's funny because I paused this video after a minute to go mess with Minecraft ideas I had, then I was trying to figure out if there was a way to do simple and efficient right click detection. I was disappointed by the complexity and inefficiency of a custom setup, so I quit the game and went back to this video, only to find out all my problems are solved by this book with some simple tweaking. Very neat! And very ironic.

could you not re-add the item to the inventory with a function? or is that not possible?

now make knowledge book that can summon moving train along with the railtrack then explode and after explode it will summon random minecfraft structure

Maybe add a stackable tag?

was so excited then you showed off it's weakness

subscribed cause of train horn. add train cam

Bedrock players is crying

I could have sworn i heard something about click detection in snapshot notes...

I've never seen this item in my entire life.

what if instead of being consumable, they run on a mana system basically

What if you give a new knowledge book in the function so that it isn't consumed?

what if they add a component which can be used to prevent consumption on use? that would be useful

can’t i just make it also replace the book at selected inventory slot?

beware, if you're holding multiple knowledge books and you right click, it uses the whole stack in one go

Hey, if you don't want to do it consumable, why don't you just set the item in the player's hand to this book? Maybe it doesn't work like that, I don't know much about datapacks, but I know that you can write commands in them, and there is a /item command.

Can you run a command that when it detects that pacific item is gone and gives it back?

sick white noise bro

i don’t understand why you can’t just have the achievement trigger a “/give @s” command and give the book to them when it’s consumed.

5:06 Oh great i can do an energy flavored zessy bar

Couldn’t you just give it back in the function for the actual spell?

couldn't you just have it to when you use it it adds a copy in the same slot of your inventory and this could be used for cooldowns like adding it back after a couple of seconds

Cool vid and all, but there's a lot of white noise in the background.

do the same thing and if not in creative: give book

1.12 update YAY.... my fav is 1.12.2... i love that update

Bro just changed data packs for the better.

Fireball!

good idea

reduce your gain, you talk decently loud, you dont need the high sensitivity on your microphone, that just adds static

Is there a way to create custom advancements and crafting recipes without data packs?

You could just set the players mainhand item to the spell bock to make it reusable

bro where tf are you recording this

oh thats pretty cool

1000th subsicriber

cool

Java didn’t have custom crafting?

3:28 dude is living in city 17

Um, warped fungus on a stick is better than carrot on a stick, it's underated lmao

I find it funny how all right click detection systems have a draw back lol Carrot on a stick is slow Endereye doesn’t work if there’s an end portal and now Knowledge book has to be consumed Mojang is not making this easy for us lmao

the best rc detection is ender eye in an advancement

I like trains 🚂

Do you know who else has a knowledge book ?

wth is a knowledge book

they're not relevant to us bedrock players though :p
