Datapack that adds wands similar to those seen in https://www.youtube.com/watch?v=I5lOKaQl-cY. Version 1.1.0+ runs on Minecraft 1.21.1

/function noi:altar/place - Places a wand editor.
/function noi:wand/create {size:Byte,base_cost:Int} - Gives a wand to the player this was run as. Size is the number of spell slots the wand you are creating has and works from 0 to 16, base_cost is the cost added after all other calculations and can be any signed Int.
/function noi:reset_settings - Sets the fake players in noi.settings to the configuration I usually use in public implementations of NCC. Run this to make the pack work when you first install it if you don't really care about the settings.
/function noi:utils/clear_attribute_modifiers - Clears any attribute modifiers that the entity this runs as might have been given by the pack.
/function noi:utils/give_potions - Gives the entity this runs as one of each potion this pack adds.
.global_max_mana - Players will gain mana over time if they have less mana than this amount. Set this to a negative number if you want to set maximum mana manually.
.mana_tick_length - The length of a mana tick, which is when mana in increased along with some other things, more on those later.
.allow_placing_wand_editors - This is a boolean (0 or 1) that allows players to sneak+rightclick while holding a wand to create a wand editor that will be removed once the wand is taken out of it. This does not affect altars placed with commands.
.limit_default_wand_textures - Boolean that, if true, limits generated wand textures to a subset of those in the resource pack.
.mana_regen - Different values do different things: 0-Players dont gain mana over time 1-Players only gain mana over time from mana potions 2-Players gain mana over time with no requirement, but also gain mana over time from potions.
The tag "noi.nowand" makes players who have it unable to cast spells and immune to targetting spells.
The scoreboard "noi.max_mana" dictates the amount of mana above which players stop generating mana. Set automatically if .global_max_mana isn't negative.
The function tag "noi:spell_conditional" is for functions that check if spells should be run the the current execution context. If you dont want spells to run, set the fakeplayer "returnvalue" to 1 for "noi.api". Do not set "returnvalue" to 0. To increase efficiency, please include the line "execute unless score returnvalue noi.api matches 0 run return 0" in the front of your function.
The item tag "#noi:spells" contains every item that can be placed into the wand editor.
The scoreboard "noi.ticks_without_spell" increments for every player every mana tick and is reset when they cast a spell.
The item entities created by the function noi:wand/create have the tag "noi.given_wand".
