Re: [sumo-user] Simulation Step TraCI call at time 0

[Jakob Erdmann <namdre.sumo@xxxxxxxxxxxxxx>]

My previous statement was made after observing the following behavior in the python interpreter (running sumo with --step-length 0.5)

>>> traci.simulation.getCurrentTime()
0
>>> traci.simulationStep(0)
[]
>>> traci.simulation.getCurrentTime()
500
>>> traci.simulationStep(500)
[]
>>> traci.simulation.getCurrentTime()
500

When I run another test with the default step length, of course it looks different:
>>> traci.simulation.getCurrentTime()
0
>>> traci.simulationStep(0)
[]
>>> traci.simulation.getCurrentTime()
1000
>>> traci.simulationStep(500)
[]
>>> traci.simulation.getCurrentTime()
1000

If you observe something different please provide input files so I can reproduce your finding.

regards,

Jakob

Well, this is not what is happening at least in my own code!

When I call simulationStep(500) (after simulationStep(0)), getCurrentTime shows me 1000!

Can you please reproduce it yourself ?
