    When I try to override the function CollectObservations(VectorSensor sensor), said sensor is null.
    I don't know if i'm using it correcly, but I can't find anywhere how to use it. I want to tell my agent where the target is.

    Thanks

    Can you send me a screen shot of your Behavior Parameters in the inspector? If the number of vector observations is greater than 1, the VectorSensor should not be null. This would be a bug

    I did another solution and null error is gone. My mistake. Sensor works fine.
