Obstacles generated on different trials appear on the same positions #12

Using 'distribute' in the configuration file does not appear to be placing obstacles differently depending on the trial. Currently obstacles are placed as follows:

  <orientation method="constant" values="0,0,0" />
  <entity quantity="2" max_trials="200">
    <cylinder id="c" height="0.5" radius="0.1500" movable="false" />
  </entity>
</distribute>`

I guess it is supposed to work like that, since argos does not know about 'trials' ? and that is why you generated the robot positions inside our loop functions differently for each trial.

Yes. As the RNG seed is the same across the trials, the objects will be positioned similarly across trials.
