Interface PreGoalCallback

All Known Implementing Classes:

Callback

public interface PreGoalCallback

Interface for callbacks that occur after a Goal's prerequisites have been met, but before any Goal-specific actions have been taken.

Callbacks implementing this interface have the opportunity to change the state of the environment, potentially causing the Goal's Action.requiresAction() to return a different answer.
