Depends a little bit about what all you want to be checking. The most consistent and reliable way is to make a custom enchantent that you either apply to the bow, or modify the data of the arrows to make them think they were shot by a how with that enchantment, but either may not be ideal for your given usecase
stray coyote
I just want it to play a function that deals damage to surrounding entities
dusty sinew
What is "it"
dusty sinew
...okay, that doesn't give me any new or useful information to provide a different answer than what I already have
stray coyote
I'll try out what you said
Oh yeah, I'm using /summon for the arrows
with a music disc
How do I do the modifying data of the arrow and which effect do I use
stray coyote
So how do i modify the data?
dusty sinew
If you're summoning the arrows, just define the NBT of it when you do so
You care about the weapon nbt
stray coyote
It isn't working
summon arrow ~ ~ ~ {Tags:["test_arrow"],weapon:{id:bow,components:{enchantments:{"trial_by_combat:test":1}}}}
This is what it's using currently
dusty sinew
Looks like correct NBT, so let's see the enchantment
stray coyote
{
"criteria": {
"example": {
"trigger": "minecraft:player_hurt_entity",
"conditions": {
"damage": {
"type": {
"direct_entity": {
"type": "minecraft:arrow",
"nbt": "{Tags:"test_arrow"}"
}
}
}
}
}
},
"rewards": {
"function": "trial_by_combat:test/test_tell"
}
}
winter glade
that's player hurt entity
you want to detect when an entity hurts a player
Something like this: https://misode.github.io/advancement/?share=NEJfVtuilJ
stray coyote
It doesnt load the shared one
the link
No wait it does
It still doesnt work even with that enchantment
winter glade
any errors in the logs?
thorny cragBOT
stray coyote
Not sure if this is mod stuff since Im launching with modrinth with mods
pretty sure it isnt though
stray coyote
Nope
It isnt detecting the damage
i gave myself the advancement manually and it worked
winter glade
oh ok
You could try removing the tag check and hitting yourself with a normal arrow
winter glade
when mobs hit you?
stray coyote
When the arrow hits a mob
dusty sinew

"criteria": {
"example": {
"trigger": "minecraft:playe...
This is an advancement, not an enchantment
stray coyote
Yeah, i know that
I have an enchantment too

}
}
this is the enchantment
dusty sinew
So you want the function to run as the entity that shot the arrow?
stray coyote
It should run at the entity
dusty sinew
The entity that got hit?
stray coyote
Yes
dusty sinew
Then you need to change the affected field
Cause right now it's trying to run the function as the entity that shot the arrow, but since you're summoning the arrow, no one shot it
dusty sinew
Did you exit and reopen the world?
stray coyote
Forgot about that but i just did it and it still doesnt work
dusty sinew
Are you positive the function isn't running? What's in the function?
stray coyote
advancement revoke @a only trial_by_combat:summon_projectile
tell @a Test
dusty sinew
Well revoking an advancement isn't gonna do anything here
And try say instead of tell
dusty sinew
Show the current enchantment?

dusty sinew
Could be because there's no attacker, try doing damaging_entity for the enchanted field
stray coyote
Didn't work
dusty sinew
Hm, not sure then
stray coyote
It works when the arrow hits me but not for mobs
dusty sinew
Doesn't seem right, what's in your function now?
