I'm a little lost on these, the end goal is for me to convert a score into an item durability in a players inventory, is that doable?
I already have the item and cooldown system with scores and stuff, just no way to visualise it

The item in question is "warped_fungus_on_a_stick" with the cooldown lasting 20s (score decreases by 1 every 4 ticks -> i've already set this up and it works)

#

the version is 1.20.1 also

Does the item vary or is it always warped fungus on a stick?

#

I can think of a very clunky way to do it where you /execute if score (entity) (score) matches (number) run give (entity) (item){Damage:(number equivalent)} 1
And then run a clear command after

I don't think there's a way to change durability of an item without just giving a new item but I may be wrong

shrewd berry
#

there is a way

Have you tried using misode? because doing what you describe cost me a total of 10 seconds on misode

you want to use the set_damage modifier, but you might have issues if you want to set the durability to a fixed amount

#

as that would be max_durability - amount_wanted = damage_to_set

#

I still don't get why they decided to call missing durability, "damage". yes the item is damaged by X amount of durability points but it is confusing when you also have damage attributes for weapons.

i've never used item modifiers before and even with the website i have no idea what im doing

shrewd berry
#

well I am afraid chewing out code scripts is frowned upon here, but if you get stuck for longer we can have a call or I can give some further pointers in dms

stiff fern

i would love some pointers if you could 🙏

For others reading some things to take into account:

set_damage modifies the damage by a percentage (-1.0 to 1.0) of the max_durability.

it by default removes durability, using a negative scale can add durability, this does require "add":true.

For single durability points this means you have to add multiple modifiers with different scales that have conditions that check the max_durability of the item (which restricts usage to a single slot!).

How about using a macro?

#

So function set_damage with storage namespace:name

#

In set_damage:

#

$Item replace entity @s (item)[Damage:$(damage)]

I did recently kind of fine a way to make item modifiers practically obsolete

#

and for this use case it might actually be good

#

so what I usually do when item modifiers cant fulfill my wishes. I

  • Summon an item at the player's position with as much hard-coded data as necessary in the summon command
  • Use a macro to change the item's data to whatever I need, in your case Item.components."minecraft:damage" set value $(damage)
  • Either do nothing and let the player pick up the item (which will place it in the next empty slot) and remove the item from the player's weapon.mainhand
  • Or, (in most use-cases preferred) use item replace entity @s weapon.mainhand from entity @n[type=item] container.0 and kill the item. (note that its preferred to give the item a temporary tag so you can make sure you make the player get the right item and kill the right item, most times not necessary though)

That doesn't make item modifiers obsolete and is usually worse

#

But as you said there's some cases where it's necessary

coral wind
#

ofc item modifiers are way simpler but like i mentioned, some things you just cant do with item modifiers

kindred tendon
#

Does not contradict what I said

coral wind
#

and i feel like this would be a case where this is better than item modifiers (if its true that you need to input a percentage)
