Spin-off of Project Creature comforts and critter jitters

Start with the creature you created in the previous project, pasting the code in here..
Incorporate the concept of forces into your ecosystem:
Try introducing other elements into the environment (food, a predator) for the creature to interact with.
Does the creature experience attraction or repulsion to things in its world?
Can you think more abstractly and design forces based on the creature’s desires or goals?
