Hi,

we are working with SUMO-GUI v.032 and the TraCI C++ code from v0.32.

Best regards,
Marc

Betreff: Re: [sumo-user] Polygon coordinates via TraCI

Hello,
shape retrieval is working in our currents tests. The error might be caused by 
mixing client version 1.0.0+ with sumo version 0.32.0 (there was a protocol 
change in 1.0.0)
regards,
Jakob

Dear Sumo-Users,

we tried to access the polygon information within the C++ TraCI, as proposed in 
a former issue (see below):
    […]
    const std::string id            = polygon_ids.at<http://polygon_ids.at>(i);
    const std::string type          = polygon.getType(id);
    const TraCIPositionVector shape = polygon.getShape(id);
    […]
Unfortunately, we obtain the following error in the SUMO-GUI (v0.32)
Error: Storage::writeUnsignedByte(): Invalid value, not in [0, 255]
Quitting (on error).
when we execute the polygon.getShape() method (see above), which is defined in 
TraCIAPI.cpp as follows:

    // 
---------------------------------------------------------------------------
    // TraCIAPI::PolygonScope-methods
    // 
---------------------------------------------------------------------------
     […]
    TraCIPositionVector
    TraCIAPI::PolygonScope::getShape(const std::string& polygonID) const {
        return myParent.getPolygon(CMD_GET_POLYGON_VARIABLE, VAR_SHAPE, 
polygonID);
    }
     […]

Can you recommend how we could solve that issue?

Regards,
Marc

Yes.

Hello everybody,



I am new to sumo. I use sumo 0.32 and was wondering if it is possible to get 
the coordinates of a polygon via TraCI.



Best regards,

Thomas
