AlternativePath Class Reference

Applies penalty to the paths it processes telling other units to avoid choosing the same path. More...

Detailed Description

Applies penalty to the paths it processes telling other units to avoid choosing the same path.

Note that this might not work properly if penalties are modified by other actions as well (e.g graph update objects which reset the penalty to zero). It will only work when all penalty modifications are relative, i.e adding or subtracting penalties, but not when setting penalties to specific values.

When destroyed, it will correctly remove any added penalty.
