Class FriendlyAgent

      appletbots.Agent
          appletbots.friendly.FriendlyAgent

public class FriendlyAgent
extends Agent

A friendly agent looks at all the other agents he can see and randomly selects one to be his friend. However, he can only make another agent his friend if the other agent does not already have the agent selected as his friend. The friendly agent then tries to move toward his friend by accelerating towards him. The agent remembers who his friend is and continues to accelerate towards him as long as the friend remains visible. If the agent ever loses sight of his friend he simply selects another one at random given the selection criteria stated above. If ever a friend cannot be found the agent accelerates in a random direction to search for one.
