I want that the satellite color changes to that of its current network manager.
When i move frame by frame by using advance function the color changes occur in the simulation but when I use the loop:
while sc.SimulationTime ~= sc.StopTime
sc.advance();
for leo_in=1:size(leo_satellites)
for nm_in=1:size(network_managers)
if detect_change_nm(leo_in,nm_in) ~= size(access_list{leo_in,nm_in}.accessIntervals,1)
detect_change_nm(leo_in,nm_in) = detect_change_nm(leo_in,nm_in) + 1;
% change color of satellite same as its network manager
leo_satellites(leo_in).matlab_sat.MarkerColor = network_managers(nm_in).gs.MarkerColor;
end
end
end
end
The simulation shows the initial color only.
Color change occuring when moving frame by frame
:
Originally they were red and not changed to green even though they must change color according to the code (using above loop)

Hi Krish,
In MATLAB, when you run a loop that updates graphical objects, you often need to manually force the graphics to render the updates. This is typically done using 'drawnow', which is a MATLAB function that forces the figure window to update and display any pending graphics events.
Here's an example of how 'drawnow' can be used:
x = 1:100;
y = sin(x);
figure
plot(x, y)
for i = 1:100
y = sin(x + i/10);
plot(x, y)
drawnow % Usage of drawnow
end
Please refer the below documentation for 'drawnow' function: https://in.mathworks.com/help/matlab/ref/drawnow.html
I hope it helps!
