Hello Frederik,
it looks like you stumbled upon a bug in TraaS.
@Mario:
in Simulation.java, line 83 should be:
return new SumoCommand(Constants.CMD_GET_SIM_VARIABLE,
Constants.VAR_POSITION_CONVERSION, x, array,
Constants.RESPONSE_GET_SIM_VARIABLE, Constants.POSITION_ROADMAP);
Also, I think all the position conversion commands need a special treatment
in SumoCommand.java:
Positions are an integral type in TracI (acting somewhat like a compound
specifier). For convert2D instead of sending a compound with 4 elements
(edge, pos, lane, returnType) you need to send a compound with 2 elements
(inputPos, returnType)
regards,
Jakob
