Class gsEnvironment

java.lang.Object
eu.su.mas.dedale.env.gs.gsEnvironment
All Implemented Interfaces:
IEnvironment
public class gsEnvironment extends Object implements IEnvironment
This class is an implementation of the IEnvironment using the graphStream library It currently offers : - several environments generators and any predefined ones that respect the DGS format - 3 types of agents (tanker, explorer and collector), - 2 type of wumpus (which generates stench), - 1 type of keyboardControlled agent (Human), that must be unique on a given instance. - Well (that generate wind and kill the agents that come in them), - 2 types of treasures (gold and diamonds) with safes with 2 opening conditions (lockpicking expertise and strength)
