The default policy is View.NOMINAL_SCREEN.
    
    Parameters:
    
    policy - the new policy
  - getCoexistenceCenterInPworldPolicy
```
public int getCoexistenceCenterInPworldPolicy()

    the number of sensor objects per PhysicalEnvironment object
  - setSensorCount
```
public void setSensorCount(int count)
```
    Set the number of sensor objects per PhysicalEnvironmnet. This is a calibration parameter that should be set before setting any sensors in the PhysicalEnvironment object. This call associates 'count' Sensors with this object, and they are indexed from 0 to count-1.
    
    Parameters:
    
    count - the new sensor count
