Potential problem with the first Focal Drift Zone
Due to the way that accessible space is calculated in both Interactive and Batch partitioning, the focus of the first FDZ that is laid down will lie within its own area. If left here it would cause Entities entering the FDZ to remain trapped within it, which is why it gives rise to a QA error.
There are several ways to remedy this:
- Drag the focus out of the FDZ’s area (this may mar the original ‘line of sight’ principle and cause Entities to move towards the FDZ in an unrealistic manner).
- Delete the FDZ and replace it with a Drift Zone (taking care to ensure that the Drift Zone’s Direction Change parameters do not create any routing anomalies).
- Trim the FDZ to the edge of the Activity Object used to initially generate the FDZs as part of the partitioning process (this is the recommended method).
