|
|
# - DESCRIPTION ------------------------
|
|
doc: >
|
|
The simulation has some advanced configuration options that are contained in this class and can be managed using 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.
|
|
# - PROPERTIES -------------------------
|
|
instance_variables:
|
|
- var_name: synchronous_mode
|
|
type: bool
|
|
doc: >
|
|
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.
|
|
- var_name: no_rendering_mode
|
|
type: bool
|
|
doc: >
|
|
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.
|
|
- var_name: fixed_delta_seconds
|
|
type: float
|
|
doc: >
|
|
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.
|
|
- var_name: substepping
|
|
type: bool
|
|
doc: >
|
|
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 and carla.WorldSettings.max_substep_delta_time. These last two parameters need to be compatible with carla.WorldSettings.fixed_delta_seconds. Enabled by default.
|
|
- var_name: max_substep_delta_time
|
|
type: float
|
|
doc: >
|
|
Maximum delta time of the substeps. If the 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.
|
|
- var_name: max_substeps
|
|
type: int
|
|
doc: >
|
|
The maximum number of physics substepping that are allowed. By default, the value is set to 10.
|
|
- var_name: max_culling_distance
|
|
type: float
|
|
doc: >
|
|
Configure the max draw distance for each mesh of the level.
|
|
- var_name: deterministic_ragdolls
|
|
type: bool
|
|
doc: >
|
|
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.
|
|
- var_name: tile_stream_distance
|
|
type: float
|
|
doc: >
|
|
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.
|
|
- var_name: actor_active_distance
|
|
type: float
|
|
doc: >
|
|
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.

|
|
- class_name: AttachmentType
|
|
# - DESCRIPTION ------------------------
|
|
doc: >
|
|
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 shows some sensors being attached to a car when spawned. Note that the attachment type is declared as an enum within the class.
|
|
|
|
# - PROPERTIES -------------------------
|
|
instance_variables:
|
|
- var_name: Rigid
|
|
doc: >
|
|
With this fixed attatchment the object follow its parent position strictly. This is the recommended attachment to retrieve precise data from the simulation.
|
|
- var_name: SpringArm
|
|
doc: >
|
|
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>).

- class_name: World
|
|
# - DESCRIPTION ------------------------
|
|
doc: >
|
|
World objects are created by the client to have a place for the simulation to happen. The world contains the map we can see, meaning the asset, not the navigation map. Navigation maps are part of the carla.Map class. It also manages the weather and actors present in it. There can only be one world per simulation, but it can be changed anytime.
|

This method applies settings contained in an object to the simulation running and returns the ID of the frame they were implemented.
|
|
warning: >
|
|
If synchronous mode is enabled, and there is a Traffic Manager running, this must be set to sync mode too. Read [this](adv_traffic_manager.md#synchronous-mode) to learn how to do it.

|
|
doc: >
|
|
This method is used in [__asynchronous__ mode](https://carla.readthedocs.io/en/latest/adv_synchrony_timestep/). It starts callbacks from the client for the function defined as `callback`, and returns the ID of the callback. The function will be called everytime the server ticks. It requires a carla.WorldSnapshot as argument, which can be retrieved from __<font color="#7fb800">wait_for_tick()</font>__. Use __<font color="#7fb800">remove_on_tick()</font>__ to stop the callbacks.

doc: >
|
|
Maximum time the server should wait for a tick. It is set to <code>10.0</code> by default.
|
|
doc: >
|
|
This method is used in [__synchronous__ mode](https://carla.readthedocs.io/en/latest/adv_synchrony_timestep/), when the server waits for a client tick before computing the next frame. This method will send the tick, and give way to the server. It returns the ID of the new frame computed by the server.
|
|
note: >
|
|
If no tick is received in synchronous mode, the simulation will freeze. Also, if many ticks are received from different clients, there may be synchronization issues. Please read the docs about [synchronous mode](https://carla.readthedocs.io/en/latest/adv_synchrony_timestep/) to learn more.

This method is used in [__asynchronous__ mode](https://carla.readthedocs.io/en/latest/adv_synchrony_timestep/). It makes the client wait for a server tick. When the next frame is computed, the server will tick and return a snapshot describing the new state of the world.

This can only be used with walkers. It retrieves a random location to be used as a destination using the __<font color="#7fb800">go_to_location()</font>__ method in carla.WalkerAIController. This location will be part of a sidewalk. Roads, crosswalks and grass zones are excluded. The method does not take into consideration locations of existing actors so if a collision happens when trying to spawn an actor, it will return an error. Take a look at [`generate_traffic.py`](https://github.com/carla-simulator/carla/blob/master/PythonAPI/examples/generate_traffic.py) for an example.
