[Version 4.10] NBT

Lets you set dynamically a mob nbt by specifying the nbt tag, the type and the value.

NBT

• nbt_tag: The name of the NBT tag. Currently nested tags are not supported
• type: The value type of the nbt tag
  "double" and "integer" represent a decimal number and an integer number
  "boolean" represent a true/false value
• value: (Range Object) represents the value to set in the nbt tag (in case of "double" and "integer"). Instead for a "boolean" value this represents the chance (0~1) for the result to be true.
• persistent_data: A true/false value that represents if the NBT tag set is inside the "ForgeData" tag
• conditions: (Conditions Object)

InsaneLib

• Insane lib adds a new ForgeData tag insanelib:explosion_causes_fire so mobs that cause explosions can also cause fire.

Examples

You can set add a random absorption amount to a mob

{
    "target": "minecraft:zombie",
    "set_nbt": [
        {
            "nbt_tag": "AbsorptionAmount",
            "type": "double",
            "value": {
                "min": 10,
                "max": 20
            }
        }
    ]
}

You can also set mods' data like EnhancedAI.
This makes a zombie have 70% chance to spawn with the ability to break blocks.

{
    "target": "minecraft:zombie",
    "set_nbt": [
        {
            "nbt_tag": "enhancedai:miner",
            "type": "boolean",
            "value": 0.7,
            "persistent_data": true
        }
    ]
}
