    // <--[command]
    // @Since 0.4.0
    // @Name vanish
    // @Arguments <entity> <state>
    // @Short changes the vanish state of an entity.
    // @Updated 2018/02/11
    // @Group Entity
    // @Minimum 2
    // @Maximum 2
    // @Named ignore_collisions (BooleanTag) Sets whether this vanished entity can collide with other entities.
    // @Named untargetable (BooleanTag) Sets whether this vanished entity can be selected as a target.
    // @Description
    // Changes the vanish state of an entity. Vanished entities don't send packets to clients,
    // but they can still affect collisions or target selection server-side. This can be adjusted
    // with the "ignore_collisions" and "untargetable" named arguments.
    // but update packets are still sent to the server and clients.
    // Related commands: <@link command invisible>invisible<@/link>.
    // @Example
    // # Vanishes the player and makes it untargetable and uncollidable.
    // - vanish <player> true --ignore_collisions true --untargetable true
