Redstone ore detection

[low briar]

Is there a way to detect block state changes and run a command to the player who activated said block state change?

More specifically, I want players who interact with redstone ore (right click or step on), to trigger a /loot give command

[vestal zealot]

You can use an advancement withe an item_used_on_block trigger or a step_on condition

[low briar]

Would that function even with powered redstone ore? If so, that is not what I want

[vestal zealot]

Powerd and unpowere redstone ore are two different block states. You can make the check more specific and make it only trigger if it has one specific block state

[low briar]

how would it detect the player, and not just the nearest entity?

I'm new to datapacks

[vestal zealot]

Advancements are a player only thing.

They also execute a reward function from and as the player

[low briar]

Would it look something like this?

{
"criteria": {
"interact_with_redstone_ore": {
"trigger": "minecraft:player_interacted_with_block",
"conditions": {
"block": "minecraft:redstone_ore"
}
}
},
"rewards": {
"function": "namespace:your_function_name"
}
}

Would that detect the interaction with redstone ore?

[low briar]

How would i go about the check for specific block states?

[vestal zealot]

I suggest using misode to make the advancement, it is much easier

[vestal zealot]

There is a field called Blockstate, look ingame with f3 what that Blockstate is called exactly and then put that in there, press the plus button and then select boolean.

[low briar]

what would the criteria be?

[vestal zealot]

Item used on block

[low briar]

Would that mean an item would be necessary to activate the advancement?

[vestal zealot]

No

If you don't specify one, it won't need one.

[low briar]

I'm confused with the requirements tab

[low briar]

Where would I find this?

In misode

[vestal zealot]

One minute, I'm on my pc in just a moment, then I can show you better

[low briar]

okay 🙂

[vestal zealot]

the block state is called lit btw

[low briar]

[lit=true]
or just
lit

Also, I'm using 1.16.5, if that changes anything

[vestal zealot]

that changes a little bit

[low briar]

I still found where I need to be

[vestal zealot]

only write lit in the field an then press the green plus

[low briar]

The only difference is location is not a condition anymore

[vestal zealot]

it will look like this

[low briar]

yes

[vestal zealot]

click on string and select boolean

then, make it true or false, depending on what you want

[low briar]

So true would mean the redstone ore that is lit would activate the datapack reward to the player?

[vestal zealot]

yes, true means only lit ores can activate it

[low briar]

I want players who activate the redstone ore to recieve a reward

[vestal zealot]

then set it to false

[low briar]

ah ok

and for the reward, would a /give loot pouch
function work?

a loot table also could work

[vestal zealot]

if the player is supposed to get an item and nothing else should happen, then a loot table is enough

[low briar]

sure

so the modded loot table is
{LootTable:"mineminenomi:chests/marine_large_base/captain"}

would I simply paste that into loot tables?

[vestal zealot]

no, only the path

[low briar]

Yea I figured that out

I see

And a display wouldn't be necessary

I would now download this and paste this into the datapacks folder?

Oh this is a json

[vestal zealot]

that or just copy the code

[low briar]

neat

advancement.json

[vestal zealot]

I was testing around but it seems you can't detect if the player r-clicks an unlit redstone ore

the advancements is apparently later in the tick list than the block state change

[low briar]

is there any workaround?

[vestal zealot]

raycast

[low briar]

raycast?

[vestal zealot]

maybe

wouldn't work, forget it

[low briar]

so this is a minecraft limitation?

damn

[vestal zealot]

yeah, it has something to do in which order the events are processed internally

[low briar]

i'm probably asking the wrong question, but did you forget to set the block id?

maybe double check if everything is there

[vestal zealot]

I did forget it

[low briar]

ah thank god

[vestal zealot]

but it doesn't seem to change anything

[low briar]

maybe dimension?

i'll try true and false to maybe see if that changes anything

[vestal zealot]

it detects the click, the only thing that doesn't work is checking for a click on an unlit ore

[low briar]

so the block state itself doesn't work

damn

[vestal zealot]

the block state changes from unlit to lit before the advancement checks it, that's why you can't check for unlit

[low briar]

awww

would a mod possibly change this?

instead of using a datapack?

[vestal zealot]

could be a possibility

[low briar]

I've got no modded coding experience 😂

thats gonna be fun

[vestal zealot]

what works though is the step on ccheck

[low briar]

step on?

even with the block state?

[vestal zealot]

stepping on unlit redstone

yes

[low briar]

That works for me

!!!!

Bro thank you 🙂

how can I repay you

[vestal zealot]

This is a 2 step process, making a predicate and an advanccement

[vestal zealot]

1,000,000€ by tomorrow would be nice

[low briar]

i can't afford that even selling my organs -_-

[low briar]

please share

[vestal zealot]

The predicate is a simple location check with a y offset of -1, the block and block state is the same as before

predicates need to be in a separate predicates folder in your datapack

[low briar]

is it exact or range?

[vestal zealot]

are you in the advancement or predicate generator?

[low briar]

oh advancement generator my bad

i'll switch to predicate

how would i reward?

[vestal zealot]

the reward comes in the advancement part

we only need the predicate because with and advancement location check, we can't have an offset

[low briar]

since you have it working, wouldn't it be easier to send me the datapack you got working?

I'm a little new on the whole datapack fomatting

[vestal zealot]

I don't have a full data pack, I was just testing the other stuff earlier.

[low briar]

so the advancement we just made is still here, with or without a position check?

the predicate is the location check?

[vestal zealot]

the predicate is the location check and we need to change the advancement to a tick advancement that references the predicacte.

[low briar]

invalid characters?

there is an error message

[vestal zealot]

everything in betweenn <> is just a placeholder

[low briar]

removed <>, now it works

i think I got the datapack formatted, i'll try running it

my game crashes?

[vestal zealot]

what?

that can't happen because of the data pack

what does the log say?

[low briar]

i'll try another instance without mods

[sonic plaza]

:information_source: Default Launcher Logs

The logs are where Minecraft displays errors when something goes wrong and can thus help you gain information about why something isn't working for you!
To open the logs:

1. Enable logs in the Minecraft Launcher
2. Start your game (or restart it if you already have an open instance)
3. Enjoy spotting errors getting much easier!

[low briar]

i'm using ATlauncher, but I think I found it

i'll try a new instance before I send the crash log

yea its the datapack

for the predicate, do I need to set an X and Z offset as ~?

[vestal zealot]

no

[low briar]

I can send a full crash log if that helps

[vestal zealot]

yeah

[vestal zealot]

Those logs don't really help

It definitely has something to do with the launcher

[low briar]

I'll try it in vanilla launcher

[vestal zealot]

could you send your pack, just to confirm it's right?

[low briar]

the previous file was a .7 zip

sent another incase you don't have 7zip

[grave breach]

Result of analysis

I found 3 issues with the structure of your datapack.

• I couldn't find pack.mcmeta. Make sure that it exists in the root of the zip.
• I couldn't find the folder data. Make sure that it exists in the root of the zip.
• I couldn't find the namespace minecraft. It isn't required, but 90% of datpacks do need to have it. If you don't use tick/load functions or you don't need to change vanilla data, then disregard this.

[vestal zealot]

you zipped a folder

ou need to zip this

[low briar]

i can't send unzipped files onto disocrd

discord

oh

[vestal zealot]

apart from that it looks ok

[grave breach]

Result of analysis

I found 1 issues with the structure of your datapack.

• I couldn't find pack.mcmeta. Make sure that it exists in the root of the zip.

[low briar]

wait

would pack format 6 be the issue?

[vestal zealot]

no

[low briar]

i'll try 5

[vestal zealot]

it just for a message ingame telling you that it's from an older version

[low briar]

ah ok

[vestal zealot]

btw both

[grave breach]

Result of analysis

I found no issues with the structure of your datapack.

[low briar]

i'll try sending you a crash log with vanilla minecraft launcher

There's the crash report, and the launcher log

I'll try changing it to "predicates.json" instead of "predicate.json"

@signal chasm

[signal chasm]

?

[low briar]

would you be able to help?

sorry to bother you

[signal chasm]

What's the question

[low briar]

the datapack I have, is currently crashing

[signal chasm]

What were you doing in the datapack?

[low briar]

We were trying to run a step on predicate alongisde an advancement.json that would detect a player walking ontop of a redstone ore

the block state of the redstone ore would go from unlit to lit, thereby activating the reward

To put it simply, I'm trying to reward players for walking ontop of redstone ore (to light it up)

For some reason the datapack simply crashes upon load

Should I wait for HeDeAn if he may be of better help?

[signal chasm]

you have an incorrect datapack, you only have the namespace "maincraft", there is no namespace "namespace" and "mineminenomi"

[low briar]

how would i go about fixing this?

[signal chasm]

you can immediately put the predicate in the advancement.
and also, what kind of loot should be on the "mineminenomi:chests/marine_large_base/captain" path?

[low briar]

"mineminenomi:chests/marine_large_base/captain" is the loot table

it's from the mod

[low briar]

I tried your changes, but the datapack no longer works as intended

it doesn't crash anymore, but it simply doesn't work

[signal chasm]

give the datapack again

[low briar]

shall i try changing the loot table reward to a vanilla one?

still does not work with "minecraft:chests/simple_dungeon"

[signal chasm]

what is the minecraft version?

[low briar]

1.16.5

[signal chasm]

oh

then idk

[low briar]

I think I have a solution, but I'll have to test it. I simply set a repeating always active command block that detects players standing upon a redstone ore[unlit]

[jagged snow]

did it work?

[low briar]

I slept. Timezone different here. I'll get back to you guys soon

[low briar]

execute as @a at @s if block ~ ~-1 ~ minecraft:redstone_ore[lit=false] run loot give @s loot mineminenomi:chests/marine_large_base/captain

[low briar]

Block detection isn't precise though, and players who fall or jump onto the redstone ore trigger the command block multiple times

[low briar]

So the problem isn't really solved...

[low briar]

not really, no

[low briar]

I think I'll try and write a mod from the ground up for this task

[celest anvil]

what is wrong

[low briar]

The datapack that we have written simply does not work

The command block workaround works, but triggers the reward too many times if players were to fall or hover over the redstone ore

[celest anvil]

:о

what's the point of the datapack

what does it do

[low briar]

It's meant to detect and give a loot table whenever a player would step on a redstone ore (that is unlit)

[celest anvil]

whaaaat

but that sounds soooooo easy

is there a blockstate for redstone ore being lit or not?

[low briar]

Yes, we have already tried that

[celest anvil]

what went wrong

[twin pilot]

And tried what, exactly? No matter what you try it's always going to at minimum be checking that blockstate

[low briar]

I have got a mod working for what I want

I can upload it to the public
