carla.AttachmentType

Class that defines attachment options between an actor and its parent. When spawning actors, these can be attached to another actor so their position changes accordingly. This is specially useful for sensors. Here is a brief recipe in which we can see how sensors can be attached to a car when spawned. Note that the attachment type is declared as an enum within the class.

Instance Variables

- **Rigid** With this fixed attatchment the object follow its parent position strictly. This is the recommended attachment to retrieve precise data from the simulation. - **SpringArm** An attachment that expands or retracts the position of the actor, depending on its parent. This attachment is only recommended to record videos from the simulation where a smooth movement is needed. SpringArms are an Unreal Engine component so [check this out](ref_code_recipes.md#attach-sensors-recipe) to learn some more about them.
Warning: The SpringArm attachment presents weird behaviors when an actor is spawned with a relative translation in the Z-axis (e.g. child_location = Location(0,0,2)).

carla.BlueprintLibrary

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 is a reference containing every available blueprint and its specifics.

Methods

- **filter**(**self**, **wildcard_pattern**) 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. - **Parameters:** - `wildcard_pattern` (_str_) - **Return:** _[carla.BlueprintLibrary](#carla.BlueprintLibrary)_ - **find**(**self**, **id**) Returns the blueprint corresponding to that identifier. - **Parameters:** - `id` (_str_) - **Return:** _[carla.ActorBlueprint](#carla.ActorBlueprint)_

carla.BoundingBox

Helper class defining a box location and its dimensions that will later be used by carla.DebugHelper or a carla.Client to draw shapes and detect collisions. Bounding boxes normally act for object colliders. Check out this recipe where the user takes a snapshot of the world and then proceeds to draw bounding boxes for traffic lights.

Instance Variables

- **extent** (_[carla.Vector3D](#carla.Vector3D)_) Vector from the center of the box to one vertex. The value in each axis equals half the size of the box for that axis. `extent.x * 2` would return the size of the box in the X-axis. - **location** (_[carla.Location](#carla.Location)_) The center of the bounding box relative to its parent actor.

Methods

carla.Client

The Client connects CARLA to the server which runs the simulation. Both server and client contain a CARLA library (libcarla) with some differences that allow communication between them. Many clients can be created and each of these will connect to the RPC server inside the simulation to send commands. The simulation runs server-side. Once the connection is established, the client will only receive data retrieved from the simulation. Walkers are the exception. The client is in charge of managing pedestrians so, if you are running a simulation with multiple clients, some issues may arise. For example, if you spawn walkers through different clients, collisions may happen, as each client is only aware of the ones it is in charge of.

The client also has a recording feature that saves all the information of a simulation while running it. This allows the server to replay it at will to obtain information and experiment with it. Here is some information about how to use this recorder.

carla.Sensor

Inherited from _[carla.Actor](#carla.Actor)_

Sensors compound a specific family of actors quite diverse and unique. They are normally spawned as attachment/sons of a vehicle (take a look at [carla.World](#carla.World) to learn about actor spawning). Sensors are thoroughly designed to retrieve different types of data that they are listening to. The data they receive is shaped as different subclasses inherited from [carla.SensorData](#carla.SensorData) (depending on the sensor).

Most sensors can be divided in two groups: those receiving data on every tick (cameras, point clouds and some specific sensors) and those who only receive under certain circumstances (trigger detectors). CARLA provides a specific set of sensors and their blueprint can be found in carla.BlueprintLibrary. All the information on their preferences and settlement can be found here, but the list of those available in CARLA so far goes as follow. Receive data on every tick.

Depth camera.
Gnss sensor.
IMU sensor.
Lidar raycast.
SemanticLidar raycast.
Radar.
RGB camera.
RSS sensor.
Semantic Segmentation camera. Only receive data when triggered.
Collision detector.
Lane invasion detector.
Obstacle detector.

Instance Variables

- **is_listening** (_boolean_) When True the sensor will be waiting for data.

- **listen**(**self**, **callback**) The function the sensor will be calling to every time a new measurement is received. This function needs for an argument containing an object type [carla.SensorData](#carla.SensorData) to work with. - **Parameters:** - `callback` (_function_) – The called function with one argument containing the sensor data. - **stop**(**self**) Commands the sensor to stop listening for data.

Dunder methods

- **\__str__**(**self**)
