Returns the statistics associated with this character.

Specified by:

getStatistics in interface Character

the character's statistics

collidedFrom

public LevelBoard.ActionResult collidedFrom(Character character)

Called when the given character collides with us. Rather than let the other character attack us, we simply say something in response, based on the list of messages. We always return FAIL since we never yield our position

Specified by:

collidedFrom in interface Character

Parameters:

character - the character that collided with us

Returns:

ActionResult.FAIL

collidedInto

public boolean collidedInto(Character character)

Called when you collide with the character. This always returns false, since we do nothing when we hit other characters.

character - the character that we collided with

Returns:

false

sendMessage

public void sendMessage(String message)

Sends a text message to the character's manager.
