This reference contains all the details the Python API. To consult a previous reference for a specific CARLA release, change the documentation version using the panel in the bottom right corner.<br>This will change the whole documentation to a previous state. Remember that the <i>latest</i> version is the `dev` branch and may show features not available in any packaged versions of CARLA.<hr>  

## carla.Actor<a name="carla.Actor"></a>
CARLA defines actors as anything that plays a role in the simulation or can be moved around. That includes: pedestrians, vehicles, sensors and traffic signs (considering traffic lights as part of these). Actors are spawned in the simulation by [carla.World](#carla.World) and they need for a [carla.ActorBlueprint](#carla.ActorBlueprint) to be created. These blueprints belong into a library provided by CARLA, find more about them [here](bp_library.md).  

### Instance Variables
- <a name="carla.Actor.attributes"></a>**<font color="#f8805a">attributes</font>** (_dict_)  
A dictionary containing the attributes of the blueprint this actor was based on.  
- <a name="carla.Actor.id"></a>**<font color="#f8805a">id</font>** (_int_)  
Identifier for this actor. Unique during a given episode.  
- <a name="carla.Actor.is_alive"></a>**<font color="#f8805a">is_alive</font>** (_bool_)

- <a name="carla.Actor.semantic_tags"></a>**<font color="#f8805a">semantic_tags</font>** (_list(int)_)  
A list of semantic tags provided by the blueprint listing components for this actor. E.g. a traffic light could be tagged with `Pole` and `TrafficLight`. These tags are used by the semantic segmentation sensor. Find more about this and other sensors [here](ref_sensors.md#semantic-segmentation-camera).

## carla.AttachmentType<a name="carla.AttachmentType"></a>
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. The snipet in [carla.World.spawn_actor](#carla.World.spawn_actor) shows some sensors being attached to a car when spawned. Note that the attachment type is declared as an enum within the class.  

### Instance Variables
- <a name="carla.AttachmentType.Rigid"></a>**<font color="#f8805a">Rigid</font>**  
With this fixed attatchment the object follow its parent position strictly. This is the recommended attachment to retrieve precise data from the simulation.  
- <a name="carla.AttachmentType.SpringArm"></a>**<font color="#f8805a">SpringArm</font>**  
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 the UE docs](https://docs.unrealengine.com/en-US/Gameplay/HowTo/UsingCameras/SpringArmComponents/index.html) to learn more about them. <br><b style="color:red;">Warning:</b> The <b>SpringArm</b> attachment presents weird behaviors when an actor is spawned with a relative translation in the Z-axis (e.g. <code>child_location = Location(0,0,2)</code>).  
- <a name="carla.AttachmentType.SpringArmGhost"></a>**<font color="#f8805a">SpringArmGhost</font>**  
An attachment like the previous one but that does not make the collision test, and that means that it does not expands or retracts the position of the actor. The term **ghost** is because then the camera can cross walls and other geometries. 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 the UE docs](https://docs.unrealengine.com/en-US/Gameplay/HowTo/UsingCameras/SpringArmComponents/index.html) to learn more about them. <br><b style="color:red;">Warning:</b> The <b>SpringArm</b> attachment presents weird behaviors when an actor is spawned with a relative translation in the Z-axis (e.g. <code>child_location = Location(0,0,2)</code>).

## carla.Client<a name="carla.Client"></a>
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](adv_recorder.md) is some information about how to use this recorder.  

### Methods

Executes a list of commands on a single simulation step and retrieves no information. If you need information about the response of each command, use the __<font color="#7fb800">apply_batch_sync()</font>__ method. [Here](https://github.com/carla-simulator/carla/blob/master/PythonAPI/examples/generate_traffic.py) is an example on how to delete the actors that appear in [carla.ActorList](#carla.ActorList) all at once.  
    - **Parameters:**

    - **Parameters:**
        - `map_name` (_str_) - Name of the map to be used in this world. Accepts both full paths and map names, e.g. '/Game/Carla/Maps/Town01' or 'Town01'. Remember that these paths are dynamic.  
        - `reset_settings` (_bool_) - Option to reset the episode setting to default values, set to false to keep the current settings. This is useful to keep sync mode when changing map and to keep deterministic scenarios.  
        - `map_layers` (_[carla.MapLayer](#carla.MapLayer)_) - Layers of the map that will be loaded. By default all layers are loaded. This parameter works like a flag mask.

    - **Parameters:**
        - `reset_settings` (_bool_) - Option to reset the episode setting to default values, set to false to keep the current settings. This is useful to keep sync mode when changing map and to keep deterministic scenarios.  
    - **Raises:** RuntimeError when corresponding.  
- <a name="carla.Client.replay_file"></a>**<font color="#7fb800">replay_file</font>**(<font color="#00a6ed">**self**</font>, <font color="#00a6ed">**name**</font>, <font color="#00a6ed">**start**</font>, <font color="#00a6ed">**duration**</font>, <font color="#00a6ed">**follow_id**</font>, <font color="#00a6ed">**replay_sensors**</font>)

## carla.Sensor<a name="carla.Sensor"></a>
<small style="display:block;margin-top:-20px;">Inherited from _[carla.Actor](#carla.Actor)_</small></br>
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](#carla.BlueprintLibrary). All the information on their preferences and settlement can be found [here](ref_sensors.md), but the list of those available in CARLA so far goes as follow.
  <br><b>Receive data on every tick.</b>
  - [Depth camera](ref_sensors.md#depth-camera).
  - [Gnss sensor](ref_sensors.md#gnss-sensor).
  - [IMU sensor](ref_sensors.md#imu-sensor).
  - [Lidar raycast](ref_sensors.md#lidar-raycast-sensor).
  - [SemanticLidar raycast](ref_sensors.md#semanticlidar-raycast-sensor).
  - [Radar](ref_sensors.md#radar-sensor).
  - [RGB camera](ref_sensors.md#rgb-camera).
  - [RSS sensor](ref_sensors.md#rss-sensor).
  - [Semantic Segmentation camera](ref_sensors.md#semantic-segmentation-camera).
  <br><b>Only receive data when triggered.</b>
  - [Collision detector](ref_sensors.md#collision-detector).
  - [Lane invasion detector](ref_sensors.md#lane-invasion-detector).
  - [Obstacle detector](ref_sensors.md#obstacle-detector).

## carla.TrafficLight<a name="carla.TrafficLight"></a>
<small style="display:block;margin-top:-20px;">Inherited from _[carla.TrafficSign](#carla.TrafficSign)_</small></br>
A traffic light actor, considered a specific type of traffic sign. As traffic lights will mostly appear at junctions, they belong to a group which contains the different traffic lights in it. Inside the group, traffic lights are differenciated by their pole index.
     
  Within a group the state of traffic lights is changed in a cyclic pattern: one index is chosen and it spends a few seconds in green, yellow and eventually red. The rest of the traffic lights remain frozen in red this whole time, meaning that there is a gap in the last seconds of the cycle where all the traffic lights are red. However, the state of a traffic light can be changed manually.

## carla.TrafficManager<a name="carla.TrafficManager"></a>
The traffic manager is a module built on top of the CARLA API in C++. It handles any group of vehicles set to autopilot mode to populate the simulation with realistic urban traffic conditions and give the chance to user to customize some behaviours. The architecture of the traffic manager is divided in five different goal-oriented stages and a PID controller where the information flows until eventually, a [carla.VehicleControl](#carla.VehicleControl) is applied to every vehicle registered in a traffic manager.
In order to learn more, visit the [documentation](adv_traffic_manager.md) regarding this module.

Tunes on/off collisions between a vehicle and another specific actor. In order to ignore all other vehicles, traffic lights or walkers, use the specific __ignore__ methods described in this same section.  
    - **Parameters:**
        - `reference_actor` (_[carla.Actor](#carla.Actor)_) - Vehicle that is going to ignore collisions.  
        - `other_actor` (_[carla.Actor](#carla.Actor)_) - The actor that `reference_actor` is going to ignore collisions with.

Sets the Traffic Manager to [synchronous mode](adv_traffic_manager.md#synchronous-mode). In a [multiclient situation](adv_traffic_manager.md#multiclient), only the TM-Server can tick. Similarly, in a [multiTM situation](adv_traffic_manager.md#multitm), only one TM-Server must tick. Use this method in the client that does the world tick, and right after setting the world to synchronous mode, to set which TM will be the master while in sync.  
    - **Parameters:**
        - `mode_switch` (_bool_) - If __True__, the TM synchronous mode is enabled.

## carla.WalkerAIController<a name="carla.WalkerAIController"></a>
<small style="display:block;margin-top:-20px;">Inherited from _[carla.Actor](#carla.Actor)_</small></br>
Class that conducts AI control for a walker. The controllers are defined as actors, but they are quite different from the rest. They need to be attached to a parent actor during their creation, which is the walker they will be controlling (take a look at [carla.World](#carla.World) if you are yet to learn on how to spawn actors). They also need for a special blueprint (already defined in [carla.BlueprintLibrary](#carla.BlueprintLibrary) as "controller.ai.walker"). This is an empty blueprint, as the AI controller will be invisible in the simulation but will follow its parent around to dictate every step of the way.  

### Methods
- <a name="carla.WalkerAIController.go_to_location"></a>**<font color="#7fb800">go_to_location</font>**(<font color="#00a6ed">**self**</font>, <font color="#00a6ed">**destination**</font>)

## carla.Waypoint<a name="carla.Waypoint"></a>
Waypoints in CARLA are described as 3D directed points. They have a [carla.Transform](#carla.Transform) which locates the waypoint in a road and orientates it according to the lane. They also store the road information belonging to said point regarding its lane and lane markings.   <br><br> All the information regarding waypoints and the [waypoint API](../../core_map/#navigation-in-carla) is retrieved as provided by the OpenDRIVE file. Once the client asks for the map object to the server, no longer communication will be needed.  

### Instance Variables
- <a name="carla.Waypoint.id"></a>**<font color="#f8805a">id</font>** (_int_)  
The identificator is generated using a hash combination of the <b>road</b>, <b>section</b>, <b>lane</b> and <b>s</b> values that correspond to said point in the OpenDRIVE geometry. The <b>s</b> precision is set to 2 centimeters, so 2 waypoints closer than 2 centimeters in the same road, section and lane, will have the same identificator.  
- <a name="carla.Waypoint.transform"></a>**<font color="#f8805a">transform</font>** (_[carla.Transform](#carla.Transform)_)  
Position and orientation of the waypoint according to the current lane information. This data is computed the first time it is accessed. It is not created right away in order to ease computing costs when lots of waypoints are created but their specific transform is not needed.

## carla.WeatherParameters<a name="carla.WeatherParameters"></a>
This class defines objects containing lighting and weather specifications that can later be applied in [carla.World](#carla.World). So far, these conditions only intervene with [sensor.camera.rgb](ref_sensors.md#rgb-camera). They neither affect the actor's physics nor other sensors.        
  Each of these parameters acts indepently from the rest. Increasing the rainfall will not automatically create puddles nor change the road's humidity. That makes for a better customization but means that realistic conditions need to be scripted. However an example of dynamic weather conditions working realistically can be found [here](https://github.com/carla-simulator/carla/blob/master/PythonAPI/examples/dynamic_weather.py).  

### Instance Variables
- <a name="carla.WeatherParameters.cloudiness"></a>**<font color="#f8805a">cloudiness</font>** (_float_)  
Values range from 0 to 100, being 0 a clear sky and 100 one completely covered with clouds.  
- <a name="carla.WeatherParameters.precipitation"></a>**<font color="#f8805a">precipitation</font>** (_float_)  
Rain intensity values range from 0 to 100, being 0 none at all and 100 a heavy rain.  
- <a name="carla.WeatherParameters.precipitation_deposits"></a>**<font color="#f8805a">precipitation_deposits</font>** (_float_)  
Determines the creation of puddles. Values range from 0 to 100, being 0 none at all and 100 a road completely capped with water. Puddles are created with static noise, meaning that they will always appear at the same locations.  
- <a name="carla.WeatherParameters.wind_intensity"></a>**<font color="#f8805a">wind_intensity</font>** (_float_)  
Controls the strenght of the wind with values from 0, no wind at all, to 100, a strong wind. The wind does affect rain direction and leaves from trees, so this value is restricted to avoid animation issues.  
- <a name="carla.WeatherParameters.sun_azimuth_angle"></a>**<font color="#f8805a">sun_azimuth_angle</font>** (_float<small> - degrees</small>_)  
The azimuth angle of the sun. Values range from 0 to 360. Zero is an origin point in a sphere determined by Unreal Engine.  
- <a name="carla.WeatherParameters.sun_altitude_angle"></a>**<font color="#f8805a">sun_altitude_angle</font>** (_float<small> - degrees</small>_)  
Altitude angle of the sun. Values range from -90 to 90 corresponding to midnight and midday each.  
- <a name="carla.WeatherParameters.fog_density"></a>**<font color="#f8805a">fog_density</font>** (_float_)  
Fog concentration or thickness. It only affects the RGB camera sensor. Values range from 0 to 100.  
- <a name="carla.WeatherParameters.fog_distance"></a>**<font color="#f8805a">fog_distance</font>** (_float<small> - meters</small>_)  
Fog start distance. Values range from 0 to infinite.

- <a name="carla.WeatherParameters.fog_falloff"></a>**<font color="#f8805a">fog_falloff</font>** (_float_)  
Density of the fog (as in specific mass) from 0 to infinity. The bigger the value, the more dense and heavy it will be, and the fog will reach smaller heights. Corresponds to <a href="https://docs.unrealengine.com/en-US/Engine/Actors/FogEffects/HeightFog/index.html#:~:text=Using%20Exponential%20Height%20Fog%20Features,-The%20sections%20below&text=Add%20a%20second%20fog%20layer,height%20falloff%2C%20and%20height%20offset">Fog Height Falloff</a> in the UE docs. <br> If the value is 0, the fog will be lighter than air, and will cover the whole scene. <br> A value of 1 is approximately as dense as the air, and reaches normal-sized buildings. <br> For values greater than 5, the air will be so dense that it will be compressed on ground level.

## carla.WorldSettings<a name="carla.WorldSettings"></a>
The simulation has some advanced configuration options that are contained in this class and can be managed using [carla.World](#carla.World) and its methods. These allow the user to choose between client-server synchrony/asynchrony, activation of "no rendering mode" and either if the simulation should run with a fixed or variable time-step. Check [this](adv_synchrony_timestep.md) out if you want to learn about it.  

### Instance Variables
- <a name="carla.WorldSettings.synchronous_mode"></a>**<font color="#f8805a">synchronous_mode</font>** (_bool_)  
States the synchrony between client and server. When set to true, the server will wait for a client tick in order to move forward. It is false by default.  
- <a name="carla.WorldSettings.no_rendering_mode"></a>**<font color="#f8805a">no_rendering_mode</font>** (_bool_)  
When enabled, the simulation will run no rendering at all. This is mainly used to avoid overhead during heavy traffic simulations. It is false by default.  
- <a name="carla.WorldSettings.fixed_delta_seconds"></a>**<font color="#f8805a">fixed_delta_seconds</font>** (_float_)  
Ensures that the time elapsed between two steps of the simulation is fixed. Set this to <b>0.0</b> to work with a variable time-step, as happens by default.  
- <a name="carla.WorldSettings.substepping"></a>**<font color="#f8805a">substepping</font>** (_bool_)  
Enable the physics substepping. This option allows computing some physics substeps between two render frames. If synchronous mode is set, the number of substeps and its time interval are fixed and computed are so they fulfilled the requirements of [carla.WorldSettings.max_substep](#carla.WorldSettings.max_substep) and [carla.WorldSettings.max_substep_delta_time](#carla.WorldSettings.max_substep_delta_time). These last two parameters need to be compatible with [carla.WorldSettings.fixed_delta_seconds](#carla.WorldSettings.fixed_delta_seconds). Enabled by default.  
- <a name="carla.WorldSettings.max_substep_delta_time"></a>**<font color="#f8805a">max_substep_delta_time</font>** (_float_)  
Maximum delta time of the substeps. If the [carla.WorldSettingsmax_substep](#carla.WorldSettingsmax_substep) is high enough, the substep delta time would be always below or equal to this value. By default, the value is set to 0.01.  
- <a name="carla.WorldSettings.max_substeps"></a>**<font color="#f8805a">max_substeps</font>** (_int_)  
The maximum number of physics substepping that are allowed. By default, the value is set to 10.  
- <a name="carla.WorldSettings.max_culling_distance"></a>**<font color="#f8805a">max_culling_distance</font>** (_float_)  
Configure the max draw distance for each mesh of the level.  
- <a name="carla.WorldSettings.deterministic_ragdolls"></a>**<font color="#f8805a">deterministic_ragdolls</font>** (_bool_)  
Defines wether to use deterministic physics for pedestrian death animations or physical ragdoll simulation.  When enabled, pedestrians have less realistic death animation but ensures determinism.  When disabled, pedestrians are simulated as ragdolls with more realistic simulation and collision but no determinsm can be ensured.  
- <a name="carla.WorldSettings.tile_stream_distance"></a>**<font color="#f8805a">tile_stream_distance</font>** (_float_)  
Used for large maps only. Configures the maximum distance from the hero vehicle to stream tiled maps. Regions of the map within this range will be visible (and capable of simulating physics). Regions outside this region will not be loaded.  
- <a name="carla.WorldSettings.actor_active_distance"></a>**<font color="#f8805a">actor_active_distance</font>** (_float_)  
Used for large maps only. Configures the distance from the hero vehicle to convert actors to dormant. Actors within this range will be active, and actors outside will become dormant.  

### Methods

Creates an object containing desired settings that could later be applied through [carla.World](#carla.World) and its method __<font color="#7fb800">apply_settings()</font>__.  
    - **Parameters:**
        - `synchronous_mode` (_bool_) - Set this to true to enable client-server synchrony.  
        - `no_rendering_mode` (_bool_) - Set this to true to completely disable rendering in the simulation.  
        - `fixed_delta_seconds` (_float<small> - seconds</small>_) - Set a fixed time-step in between frames. <code>0.0</code> means variable time-step and it is the default mode.
