I got the "numVehicles" parameter from the .ini file using the following codification:

long numV = Veins::TraCIScenarioManagerLaunchdAccess().get()->par("numVehicles").longValue();

I hope this can help you.

  • Cool! I needed to add one include in my BaseWaveApplLayer.h and your code works. `#include "veins/modules/mobility/traci/TraCIScenarioManagerLaunchd.h"` Now I can get all value from [TraCIScenarioManagerLaunchd.ned](https://github.com/namnatulco/veins/blob/master/src/veins/modules/mobility/traci/TraCIScenarioManagerLaunchd.ned) using the [TraCIScenarioManagerLaunchdAccess](https://github.com/namnatulco/veins/blob/master/src/veins/modules/mobility/traci/TraCIScenarioManagerLaunchd.h#L64).get(). Thank you for all the help : ). – João Batista Oct 13 '16 at 02:17

Reading parameter values of a module can be done via a call to this module's par(...) method.

I would highly recommend doing the TicToc tutorial, where this is demonstrated succinctly

  • Hello Sommer. I have read the TicToc tutorial. I'm using `par(...)`, but I can't get values from somes module. For exemple, I want get the value of `*.manager.numVehicles` (from veins/src/modules/mobility/traci/TraCIScenarioManagerLaunchd.ned), I tried with `par(...)`, but he don't accept . or *, so I created one variable `numVehicles` (to use `*.car[*].appl.numVehicles`) on BaseWaveApplLayer.ned to get this value and I have to make sure that with both have the same value. Maybe has one way with `par(...)` to get this value directly, but I don't know how. Thanks for your help until now : ). – João Batista Jan 31 '16 at 22:24
