    Syntax

    restart(scene)

    Description

    restart(scene) resets the simulation of the UAV scenario scene. The function resets platforms' poses and sensor readings to NaN, resets the CurrentTime property of the scenario to zero, and resets the IsRunning property of the scenario to false.

    Create a UAV scenario.

    scene = uavScenario("UpdateRate",100,"StopTime",1);

    Add the ground and a building as meshes.

    addMesh(scene,"Polygon", {[-50 0; 50 0; 50 50; -50 50], [-3 0]}, [0.3 0.3 0.3]);
addMesh(scene,"Cylinder", {[10 5 5], [0 10]}, [1 1 0]);

    Create a UAV platform with a specified waypoint trajectory in the scenario. Define the mesh for the UAV platform.

    traj = waypointTrajectory("Waypoints", [0 -20 -5; 20 0 -5], "TimeOfArrival", [0  1]); 
uavPlat = uavPlatform("UAV",scene,"Trajectory", traj); 
updateMesh(uavPlat,"quadrotor",{10},[1 0 0],eul2tform([0 0 0]));

    Simulate and visualize the scenario.

    setup(scene); 
while advance(scene) 
    show3D(scene); 
    drawnow update 
end
