      CARLA provides a library of blueprints for actors in carla.BlueprintLibrary with different attributes each.

  - class_name: ActorBlueprint
    # - DESCRIPTION ------------------------
    doc: >
      CARLA provides a blueprint library for actors that can be consulted through carla.BlueprintLibrary. Each of these consists of an identifier for the blueprint and a series of attributes that may be modifiable or not. This class is the intermediate step between the library and the actor creation. Actors need an actor blueprint to be spawned. These store the information for said blueprint in an object with its attributes and some tags to categorize them. The user can then customize some attributes and eventually spawn the actors through carla.World.
    # - PROPERTIES -------------------------
    instance_variables:
    - var_name: id
      type: str
      doc: >
        The identifier of said blueprint inside the library. E.g. `walker.pedestrian.0001`.
    - var_name: tags
      type: list(str)
      doc: >
        A list of tags each blueprint has that helps describing them. E.g. `['0001', 'pedestrian', 'walker']`.
    # - METHODS ----------------------------
    methods:
    - def_name: has_attribute
      return: bool
      params:
      - param_name: id
        type: str
        doc: >
          e.g. `gender` would return **True** for pedestrians' blueprints.
      doc: >
        Returns <b>True</b> if the blueprint contains the attribute `id`.
    # --------------------------------------
    - def_name: has_tag
      return: bool
      params:
      - param_name: tag
        type: str
        doc: >
          e.g. 'walker'
      doc: >
        Returns <b>True</b> if the blueprint has the specified `tag` listed.

      return: bool
      params:
      - param_name: wildcard_pattern

      doc: >
        Returns <b>True</b> if any of the tags listed for this blueprint matches `wildcard_pattern`. Matching follows [fnmatch](https://docs.python.org/2/library/fnmatch.html) standard.

      - param_name: value
        type: str
        doc: >
          The new value for said attribute.
      doc: >
        If the `id` attribute is modifiable, changes its value to `value`.
    # --------------------------------------
    - def_name: __iter__

  - class_name: BlueprintLibrary
    # - DESCRIPTION ------------------------
    doc: >
      A class that contains the blueprints provided for actor spawning. Its main application is to return carla.ActorBlueprint objects needed to spawn actors. Each blueprint has an identifier and attributes that may or may not be modifiable. The library is automatically created by the server and can be accessed through carla.World.

        [Here](bp_library.md) is a reference containing every available blueprint and its specifics.

      doc: >
        Filters a list of blueprints matching the `wildcard_pattern` against the id and tags of every blueprint contained in this library and returns the result as a new one. Matching follows [fnmatch](https://docs.python.org/2/library/fnmatch.html) standard.
