About the plugin

Attribute modifiers, formerly known as the attributes plugin, adds new procedure blocks that allow you to apply temporary or permanent modifiers to items and entities.

Example usage for items

The item modifier procedure blocks can only be used with the calculating attribute modifiers global trigger and enclosed in the For slot [...] do procedure block.

Example usage for entities

Most of the entity modifier blocks have been moved to core MCreator, if you plan to update to 2025.3, first remove the plugin's entity modifier blocks from your procedures if they aren't the procedure blocks using registry names.

Comments

I also can't help but notice that there aren't any "from_mod" blocks of the "add_modifier" and "remove_modifier" blocks

Meant "remove_modifier_uuid" not "remove_modifier"

The "remove attribute modifier of entity" block always gives a build error in the latest version of mcreator for neoforge 1.20.4

It seems to be some issues with the attribute: "STEP_HEIGHT_ADDITION" in 1.20.4

Was it removed I wonder?

Nerdy, Please need a help! So the Add or remove modifier block is working as intended but can you please tell me how can I make those only "Add" modifier blocks work? I'm new to the mcreator... what does "Deprecated - Use attribute modifiers for item" means. Please help

Im not the original author, I just maintain the plugin for new versions

although you said that, there's still important stuff to do with this plugin.
fix modifier block (when you use modifier procedure block, all other item modifiers are gone).

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
