Wolves Sheep Predation

Each step, wolves and sheep move around the environment randomly and reproduce. If a sheep and wolf agent share the same position, the sheep agent dies and the wolf agent gains a certain amount of energy. Wolves lose energy as they move around and if it reaches 0 they die.

Wolves, Sheep, Grass: The wolves agents share the same behavior as the one above. Sheep now gain energy as they eat grass, lose energy as they move around, and die once their energy reaches 0. Grass patches turn brown if they have been eaten and slowly regrow after a certain amount of time.
