Hi Milad,
The vector strings are directly command line arguments passed to 'sumo.exe'
or 'sumo-gui.exe'. See
https://sumo.dlr.de/docs/Basics/Using_the_Command_Line_Applications.html#setting_options_on_the_command_line
So you need a file called 'net.net.xml' in your current directory. Or if
you have another file like 'myname.net.xml', just replace 'net.net.xml'
with that filename.
In your MyPedestrian.cpp, sumo is now being called like on a command prompt
with: "sumo-gui.exe -c main.sumocfg". You can actually try that command in
a command prompt window in the directory where 'main.sumocfg' is located.
There is not more magic than that.
Creating a .sumocfg is explained on the SUMO website. It just describes a
collection of files and properties to load to make up a SUMO project. E.g.
*<configuration> <input> <net-file value="myfile.net.xml"/>
<route-files value="myfile.rou.xml"/> </input> <time> <begin
value="0"/> <end value="-1"/> <step-length value="0.1"/>
</time></configuration>*
It would be good to read a bit more on SUMO on the website; they will give
some insight on how it all works.
Cheers,
Ruud
