ise.mace.models.Food

Model for defining that types of foods that {@link AbstractAgent agents}can {@link Hunt hunt}.

Each type of food is defined by the amount of nutrition it provides, and the number of agents that have to tyr and hunt it in order to be successful. The nutrition value is then divided equally amount between all the hunters in the {@link HuntingTeam team} who hunted this food @see AbstractAgent#chooseFood() @see Environment#availableFoods() @see TurnType#GoHunt
