For example, to set autopilot on some actors, we could use: [sample_code](10c5f6a482/PythonAPI/examples/spawn_npc.py (L126)). We don't have control about the response of each command. If we need that, we can use `apply_batch_sync()`. - **Parameters:** - `commands` (_list_) – A list of commands to execute in batch. Each command has a different number of parameters. Currently, we can use these [commands](#command.ApplyAngularVelocity): SpawnActor DestroyActor ApplyVehicleControl ApplyWalkerControl ApplyTransform ApplyVelocity AplyAngularVelocity ApplyImpulse SetSimulatePhysics SetAutopilot. - **apply_batch_sync**(**self**, **commands**, **due_tick_cue**) This function executes the whole list of commands on a single simulation step, blocks until the commands are executed, and returns a list of [`command.Response`](#command.Response) that can be used to determine whether a single command succeeded or not.

carla.Waypoint

Waypoints in CARLA are described as 3D directed points. They store a certain 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. All of this information is retrieved as provided by the OpenDRIVE file.

Instance Variables

- **id** (_int_) The identificator is generated using a hash combination of the road, section, lane and s values that correspond to said point in the OpenDRIVE geometry. The s 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. - **transform** (_[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. - **road_id** (_int_) OpenDRIVE road's id. - **section_id** (_int_) OpenDRIVE section's id, based on the order that they are originally defined. - **lane_id** (_int_) OpenDRIVE lane's id, this value can be positive or negative which represents the direction of the current lane with respect to the road. For more information refer to OpenDRIVE [documentation](http://www.opendrive.org/docs/OpenDRIVEFormatSpecRev1.4H.pdf#page=20). - **s** (_float_) OpenDRIVE s value of the current position. - **is_junction** (_bool_) True if the current Waypoint is on a junction as defined by OpenDRIVE. - **lane_width** (_float_) Horizontal size of the road at current s. - **lane_change** (_[carla.LaneChange](#carla.LaneChange)_) Lane change definition of the current Waypoint's location, based on the traffic rules defined in the OpenDRIVE file. It states if a lane change can be done and in which direction. - **lane_type** (_[carla.LaneType](#carla.LaneType)_) The lane type of the current Waypoint, based on OpenDRIVE 1.4 standard. - **right_lane_marking** (_[carla.LaneMarking](#carla.LaneMarking)_) The right lane marking information based on the direction of the Waypoint. - **left_lane_marking** (_[carla.LaneMarking](#carla.LaneMarking)_) The left lane marking information based on the direction of the Waypoint.

Methods

- **get_left_lane**(**self**) Generates a Waypoint at the center of the left lane based on the direction of the current Waypoint, regardless if the lane change is allowed in this location. Can return None if the lane does not exist. - **Return:** _[carla.Waypoint](#carla.Waypoint)_ - **get_right_lane**(**self**) Generates a waypoint at the center of the right lane based on the direction of the current waypoint, regardless if the lane change is allowed in this location. Can return None if the lane does not exist. - **Return:** _[carla.Waypoint](#carla.Waypoint)_ - **next**(**self**, **distance**) Returns a list of waypoints at a certain approximate `distance` from the current one. It takes into account the road and its possible deviations without performing any lane change and returns one waypoint per option. The list may be empty if the road ends before the specified distance, for instance, a lane ending with the only option of incorporating to another road. - **Parameters:** - `distance` (_float_) – The approximate distance where to get the next waypoints. - **Return:** _list([carla.Waypoint](#carla.Waypoint))_ - **next_until_lane_end**(**self**, **distance**) Returns a list of waypoints from this to the end of the lane separated by a certain `distance`. - **Parameters:** - `distance` (_float_) – The approximate distance between waypoints. - **Return:** _list([carla.Waypoint](#carla.Waypoint))_ - **previous**(**self**, **distance**) This method does not return the waypoint previously visited by an actor, but a list of waypoints at an approximate `distance` but in the opposite direction of the lane. Similarly to **next()**, it takes into account the road and its possible deviations without performing any lane change and returns one waypoint per option. The list may be empty if the road ends before the specified distance, for instance, a lane ending with the only option of incorporating to another road. - **Parameters:** - `distance` (_float_) – The approximate distance where to get the previous waypoints. - **Return:** _list([carla.Waypoint](#carla.Waypoint))_ - **previous_until_lane_start**(**self**, **distance**) Returns a list of waypoints from this to the start of the lane separated by a certain `distance`. - **Parameters:** - `distance` (_float_) – The approximate distance between waypoints. - **Return:** _list([carla.Waypoint](#carla.Waypoint))_ - **\__str__**(**self**)
