set
Description
set(
sets the value of the specified parameter in the ScenarioSim
,Name=Value
)ScenarioSimulation
object ScenarioSim
.
set(
replays the scenario ScenarioSim
,"SimulationCommand","Replay",FileName
) ScenarioSim
from the file FileName
when the replay command is issued.
Examples
Set Scenario Simulation Parameters
Create ss
, a ScenarioSimulation
object
rrApp = roadrunner("C:\Project\TestHighwayRoute"); openScenario(rrApp,"myScenario1"); ss = createSimulation(rrApp);
Set the simulation step size.
set(ss,StepSize=0.02)
Set the maximum simulation time.
set(ss,MaxSimulationTime=1200)
Set the simulation pacer status.
set(ss,PacerStatus="On")
Set the simulation pace.
set(ss,SimulationPace=1)
Set command to pause the simulation.
set(ss,SimulationCommand="Pause")
Turn on logging for the simulation.
set(ss,Logging="On")
Input Arguments
ScenarioSim
— RoadRunner Scenario simulation
ScenarioSimulation object
RoadRunner Scenario simulation, specified as a ScenarioSimulation
object.
Example: set(ss,MaxSimulationTime=1000)
FileName
— Name of file from which scenario is replayed
string scalar | character vector
Name of the file with .rrsimlog
extension from which a scenario
simulation is replayed, returned as a string or character vector. A simulation log can
be replayed only if the linked .rrscenario
and
.rrscene
files have not been modified after the simulation log was
saved.
If a scenario is open in theRoadRunner Scenario editor, and you then try to replay a different scenario from the corresponding simulation log, then the latter scenario also opens before its replay sequence begins.
Example:
set(ScenarioSim,"SimulationCommand","Replay","simulationLogFile1")
replays a scenario from a simulation log file named
simulationLogFile1.rrsimlog
in the current folder.
Name-Value Arguments
Specify optional pairs of arguments as
Name1=Value1,...,NameN=ValueN
, where Name
is
the argument name and Value
is the corresponding value.
Name-value arguments must appear after other arguments, but the order of the
pairs does not matter.
Example: set(ss,SimulationCommand="Start")
starts playing the
specified simulation.
StepSize
— Step size of simulation
0.02
(default) | double
Step size of the simulation in seconds, specified as a double.
MaxSimulationTime
— Maximum simulation time
1000
(default) | double
Maximum simulation time in seconds, specified as a double.
PacerStatus
— Pacer status of simulation
"On"
| "Off"
Pacer status of the simulation, specified as one of these strings.
"On"
— Pacing is turned on. You can slow down or speed up the simulation."Off"
— Pacing is turned off. You cannot slow down or speed up the simulation.
SimulationPace
— Pace of simulation
double
Pace of the simulation, specified as a double. The pace indicates speed of the simulation run.
Logging
— Logging status of the simulation
"On"
| "Off"
Logging status of the simulation, specified as one of these strings.
"On"
— Logging is turned on. You can retrieve simulation and actor information at each time step."Off"
— Logging is turned off. You cannot retrieve simulation and actor information at each time step.
SimulationCommand
— Command to control simulation
"Start"
| "Pause"
| "Continue"
| "Stop"
| "Step"
| "Replay"
Command to control simulation, specified as one of these strings.
"Start"
— Start playing an unstarted or stopped simulation."Pause"
— Pause a running simulation."Continue"
— Continue playing a paused simulation."Stop"
— Stop playing a running or paused simulation."Step"
— Move the simulation forward by one time step."Replay"
— Replay a scenario from the simulation log stored inFileName
.
Version History
Introduced in R2022aR2023a: Replay a scenario simulation from a saved file
Starting in R2023a, you can use the set
function to replay a
scenario simulation from a saved .rrsimlog
file.
