车辆的当前位置？

Question

我正在使用静脉 5.1。我正在尝试使用 TraCIMobility 中的 getCurrentPosition() 函数。但它说没有这样的功能？如何获取节点的当前位置？

我的应用程序源代码：

bool VeinsInetSampleApplication::startApplication()


if (getParentModule()->getIndex() == 0) {
    auto callback = [this]() {




        veins::TraCICommandInterface::Junction traciJunction = traci->junction("node4");
        veins::TraCICommandInterface::Junction traciJunction1 = traci->junction("node6");
        veins::Coord nodes1 = traciJunction.getPosition();
        veins::Coord nodes2 = traciJunction1.getPosition();
        veins::Coord veh_pos = mobility_veins->getPositionAt(simTime());
    
    };
    timerManager.create(veins::TimerSpecification(callback).interval(SimTime(6, SIMTIME_S)));
}

return true;

我已经在头文件中定义了mobility_veins

class VEINS_INET_API VeinsInetApplicationBase : public inet::ApplicationBase, public inet::UdpSocket::ICallback {
protected:
veins::VeinsInetMobility* mobility;
TraCIMobility* mobility_veins;
veins::TraCICommandInterface* traci;
veins::TraCICommandInterface::Vehicle* traciVehicle;
veins::TimerManager timerManager{this};

inet::L3Address destAddress;
const int portNumber = 9001;
inet::UdpSocket socket;

您可以通过以下方式获取当前位置：

 mobility->getPositionAt(simTime());
