Summary

AttributeSetter 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…

The mod can edit more than attributes, including food values, merging attributes from different mods, item durability, tooltips, etc etc, all through datapacks.

Server Side Only

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.

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
