Examples

Here are several complete examples of restriction files. You can copy these into your config/itemrestrictions/restrictions/ folder (ensure you create subfolders for namespaces, e.g., config/itemrestrictions/restrictions/my_server/example.json).

1. Locked Diamond Sword (Job Level Requirement)

Prevents crafting, using, or hurting entities with a Diamond Sword unless the player is at least level 30 Hunter.

{
    "icon": {

    },
    "types": [
        "cant_craft",
        "cant_use_item",
        "cant_hurt_entity",

            "item": {
                "id": "minecraft:diamond_sword"
            }
        },
        {
            "type": "jobsplus:job_level",
            "inverted": true, // Restrict if NOT at level 30
            "job": "jobsplus:hunter",
            "level": 30
        }
    ]
}

2. No TNT in the Overworld
