    Description

    removeObserver(ScenarioSim,ObserverName) removes the observer named ObserverName from the ScenarioSimulation object ScenarioSim.

    example

    Examples

    collapse all

    1. Create ScenarioSim, a ScenarioSimulation object.

      rrApp = roadrunner("C:\RoadRunnerProject");
openScenario(rrApp,"TrajectoryCutIn");
ScenarioSim = createSimulation(rrApp);

    2. Create the class mySysObserver, which inherits from matlab.System base class. The mySysObserver class represents an observer.

      classdef mysysObserver < matlab.System

properties(Access=private)
% …
end
methods
% constructor for the System object
function obj = mysysObserver()
end
end


methods(Access = protected)

%reset the values
function resetImpl(obj)
obj.mScenarioSimObj = Simulink.ScenarioSimulation.find("ScenarioSimulation", ...
  "SystemObject", obj);
obj.mScenarioSimActorList = [];
obj.mIsPacingTurnedOff = false;
end



% get the required parameter values
function stepImpl(obj)
mSimulationPace = obj.mScenarioSimObj.get("SimulationPace");
mScenarioSimActorList = obj.mScenarioSimObj.get("ActorSimulation");
end
end
end

    3. Add the observer to the scenario.

      obsStatus = addObserver(ScenarioSim,"ReadPaceandActors","mysysObserver");

    4. Remove the observer from the scenario.

      removeObserver(ScenarioSim,"ReadPaceandActors");

    Input Arguments

    RoadRunner Scenario simulation, specified as a ScenarioSimulation object.

    Example: removeObserver(ScenarioSim, "ObservingRedTruck")

    Name of observer to remove, specified as a string or character vector.
