About this Mod

Summary

Attribute Setter Is a simple lightweight mod that can change the default attributes of any living entity or item through datapacks, inspired by Jackiecrazy's Attributizer and Custom Item Attributes(CIA).
This mod was created for modpack creators and server owners to easily balance entities and items, changing their health, damage, follow range, etc...

Supports CuriosAPI

Although we(I) don't support trinkets yet(it's harder to implement, trinkets doesn't have the event that I use in Curios), if you want to add attributes to any curios, just set the slot to the appropriate name.

Server Side Only Required

If you are a server owner, your players DO NOT need to download this mod. Simply put it into your mods folder and configure it as you wish. Of course it works on singleplayer as it has an integrated server running. Although keep in mind that your players won't see the changed attributes, they'll still work, but the items will appear with their vanilla attributes.

Client Side Optional

If installed in client-side, besides showing the changed attributes, this mod also collapses item attributes into vanilla "green attributes" if they're already present

Vanilla Behaviour AttributeSetter

Example

The following file attributes.json will change all creepers' health to 100, instead of the normal 20.

{
    "minecraft:creeper": [
        {
            "attribute": "minecraft:generic.max_health",
            "value": 100,
            "operation": "BASE"
        }
    ]
}

Creeper has spawned with 100 health

Frequently Asked Questions

AttributeSetter server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.8). You can switch loaders with one click in the panel.

Is AttributeSetter compatible with fabric and forge and neoforge and quilt?

AttributeSetter officially supports fabric, forge, neoforge, quilt for Minecraft 1.21.8, 1.21.7, 1.21.6. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with AttributeSetter – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if AttributeSetter consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
