and there is no procedure block for custom mod attributes for entity modifiers

Not my problem, if all people are going to do is complain then I might aswell not update the plugin at all.

guys chill, he said this is not his plugin. coding is hard and specially if it's not your own code. he is managing and updating this plugin is already a nice thing

I have been trying to find a mod like this for so long so , are you going to update this plugin (not saying you to hurry it) because I would LOVE to use this in my upcoming projects

Also all the "Get value of attribute" base, non-base, modded, internal doesn't matter they all seem to be broken and just keep returning null with a custom attribute.

I don't know if you read these comments Nerdy but if you do please can you fix these 2 issues I've mentioned even if it isn't your code.

God ok, I figured it out. I was just being stupid and forgot to add "Player" to the attribute. Don't mind me. The Issue below is still an issue though but seemingly easy to fix.

do you know how to add a attribute to and existing item or armor without removing/ replacing the old attributes? if you do please let me know

The Data List on the block "Remove modifier with UUID from an entity" only include Vanilla entries and not modded ones from the plugin.

this one seems to be fixable by just adding: "customEntryProviders": "attribute" to the block but the one above this one alludes me still.

I think at least

I think i fixed the issue on attribute modifiers in items
you can check it in my last post how i managed to add it to items without breaking anything and works even if there are multiples modifiers for the single attribute.
If you can check it here is the code, pretty easier to use and hope it helps you.

is my first code in java

Thank you! I was hoping for an updated version for 2023.4

Hey this might be a dumb question but I'm not at my PC right now so I just want to check. Is there any way to change reach with this plugin, since its technically a attribute afaik, it would be incredibly useful for me.

Im sorry to keep it up but i think i found the issue
Im not sure if you can look directly into the code but the bug of all attributes getting deleted seems to occur when you use UUIDMost UUIDLeast (or even maybe just a typo when merging data)
I know this because i replicate the same result when using commands, ended up with an armor piece with broken attributes as here. If you can see it maybe it will be a nice idea to try

Update: I checked the code of the plugin and i think i found the issue
The plugin uses UUID.fromString() to add the UUID to an attribute, i tested this with commands in creative and found out that this cause the same issue of other attributes getting deleted (even the "When on main hand:" text), this might be because UUID.fromString returns a hexadecimal representation of the UUID but only the integer array UUID seems to work in minecraft (no idea why was this working before but it looks like just minecraft decided to not work with hexadecimal anymore)
You can test this yourself with commands using /data modify
If you can modify this to just convert the UUID string directly into integer-array format this plugin will work again

so i tried this plugin in hopes it would work but looks like it doesnt
whenever i try to add a modifier to an item, it breaks all others attributes the item has and in the end gives nothing.
I have no idea why does this happen but it is happening since they changed the way modifiers were added to items
I would like to know if there is a fix to this

PD: i have tried to add +5 hp to a chestplate when is used
and doing it removed all other attributes including the one im already trying to add

I'm not the original author of this plugin, but I'll see what I can do when I'm free.

you can also just edit the item using commands or summon the item with attributes using mcstacker and the execute command function, I stopped using most plugins like this bc when they break my mod breaks and thats annoyin

do you mind leaving a little example? Im trying to use commands now but all of them result in syntax error etc

idk how to uhh send screenshots here I dont think I can but basically I used the mcstacker website to make a command, then I use nbt data/global persistant player data to set as some of the commands variables, and while im setting this up I bind this to an item so I can read a printout inchat/in console to see what the commands doing so if im being dumb it becomes really appartent what I have messed up, in the case of your attributes thing uhh I am ganna see if I cant dm you my attributes thing real quick if I can figure that out lmao I only currently use it to set health of entities but it can be used for anything on the mcstacker website

I mean in my case is just executing the command for the player to apply or update the modifier (enchantment levels change the value of the modifier) I already have a procedure to detect every time the player wear armor so i just need the command to work
if you can please thank you
