Actions

An action is a pair (avatar, location). The action is register onto the WorldMap by being appended to a cell.

The action is processed by calling the apply function.

• if the action is legal it is applied
• if not it is rejected

The exposed interface is:

• apply
  • has to return true if application succeeded
  • attaches an event to the avatar
• is_legal
  • returns if an action is legal from the point of view of the map
  • the action gets applied or rejected accordingly
• reject
  • attaches a (failed) event to the avatar

Each of the 3 elements of the interface are implemented differently by different types of actions.
