Variant Conditions

This is a list of conditions that your variant can use. Conditions are handled only on the server and are used to define when a variant should be sent to the client.

Conditions are defined in the conditions array in the variant json. They will look something like this:

{
    "type": <condition id>,
    ... condition args
}

• type: The id of the condition.
• exclusive: Boolean. Default false. If this is true and the condition passes, then the API will skip random selection and this will be the only variant. Good for breeding.

Biome

ID: variantapi:biome_condition

Args:

• biome (Identifier): Can be the raw biome or biome tag

Defines which biomes a variant can spawn in.

Structure

ID: variantapi:structure_condition

Args:

• strucure (Identifier): Can be raw structure or structure tag

Defines structures that the variant should spawn in

Breeding

ID: variantapi:breeding_condition

Args:

• father (Identifier): 1st Variant id to require
• mother (Identifier): 2nd Variant id to require

Father and Mother are simply for name-sake, this condition will pass as long as the two parents have these variants.

L2 Hostility Level

ID: l2hostility:l2hostility_level_condition

Args:

• min (Integer): The mob level at which this variant will start showing

This condition is only used if you have the L2 Hostility Mod installed.

Moon Phase

ID: variantapi:moon_phase_condition

Args:

• size (Float 0-1): The minimum moon size for this variant

This condition will pass if the worlds moon size is bigger than the size specified. The worlds moon sizes are as follows: {1.0F, 0.75F, 0.5F, 0.25F, 0.0F, 0.25F, 0.5F, 0.75F}

Name

ID: variantapi:name_condition

Args:

• name (String): The custom name of the mob to match (case-sensitive)

This condition will pass if a mob is given a nametag matching its name

Predicate

ID: variantapi:predicate_condition

Args:

• predicate (Identifier): The predicate to test for

Any Of

ID: variantapi:any_of

You can nest other conditions inside of this one, and if any of them pass, this condition will pass.
