getAdditionalArgs

Declares extra, per-instance parameters this entity type accepts — values baked into an individual entity's persistent data at creation, so two entities of the same type can carry different settings.

Override to declare the parameters (ordered name → PDC type pairs). They are then:

• supplied positionally at spawn — spawnEntity(location, listOf("5")), or via the built-in /emob <entity> <arg1> <arg2> … command (parsed in declared order);

• read back with additionalKey + EffectiveDataContainerUtils, typically inside editEntity or a behaviour.

override fun getAdditionalArgs() = AdditionalArgs(
    ExamplePlugin.instance,
    listOf("power" to PersistentDataType.INTEGER)
)
// reading it back:
val power = EffectiveDataContainerUtils.getContainerValue(
    entity, additionalKey("power"), PersistentDataType.INTEGER
)

Returns null (the default) for entities without extra parameters.
