- class_name: WorldSettings
# - 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_substeps 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.WorldSettings.max_substeps 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.

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: >

- var_name: spectator_as_ego
type: bool
doc: >
Used for large maps only. Defines the influence of the spectator on tile loading in Large Maps. By default, the spectator will provoke loading of neighboring tiles in the absence of an ego actor. This might be inconvenient for applications that immediately spawn an ego actor.
# - METHODS ----------------------------
methods:
- def_name: __init__
params:
- param_name: synchronous_mode
type: bool
default: False
doc: >
Set this to true to enable client-server synchrony.
- param_name: no_rendering_mode

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>).
- var_name: SpringArmGhost
doc: >
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>).

Function with a snapshot as compulsory parameter that will be called when the client receives a tick.
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.

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.

- def_name: set_pedestrians_cross_factor
params:
- param_name: percentage
type: float
doc: >
Sets the percentage of pedestrians that can walk on the road or cross at any point on the road. Value should be between `0.0` and `1.0`. For example, a value of `0.1` would allow 10% of pedestrians to walk on the road. __Default is `0.0`__.
note: >
Should be set before pedestrians are spawned.
# --------------------------------------
- def_name: set_pedestrians_seed
params:
- param_name: seed
type: int
doc: >
Sets the seed to use for any random number generated in relation to pedestrians.
note: >
Should be set before pedestrians are spawned.
If you want to repeat the same exact bodies (blueprint) for each pedestrian, then use the same seed in the Python code (where the blueprint is choosen randomly) and here, otherwise the pedestrians will repeat the same paths but the bodies will be different.
