Due: March 28th

For this assignment you will be expanding the simple Humans versus Zombies program we've been developing in class.

Include the following features in the Humans versus Zombies program (you may continue building on your current program or start over from one of the on-line versions, on the schedule):

• Add a new breed: dogs dog.
• Give the dogs their own shape.
• When the dogs move they should move towards the closest zombie within 3. If there are no zombies within 3 then the dogs should move towards the closest human.
• In combat each dog should count as 3 zombies.
• Dogs should occasionally hatch from other dogs.
• Add at least one type of specialized patch that has an affect on humans, zombies, or dogs. Possiblities include: patches that heal humans, patches that humans amd zombies can't enter (barriers), patches only humans can enter (buildings), patches where humans kill zombies, patches that "sprout" dogs, etc.
• Fill in the info tab. Include your name under "What is it?" Make sure to fill in all of the other sections. Be sure to include a discription of the model. What the patches do, when dogs hatch, etc.

Turn in: Save your project as [scratchname]Zombies3.nlogo. E.g. my project would be saved as tsoule89Zombies3.nlogo (without the []'s). Email the project as an attachment to both TAs. Make the subject of the email CS112Assignment7.

Note: to make the dogs move properly you will need an ifelse statement with a Boolean and, like:
ifelse( count zombies > 0 and (distance (min-one-of zombies [distance myself]) < 3))
[ ;; if part
   ;; Code for dogs to move toward zombies
]
[ ;; else part
   ;; Code to move toward humans, remember to check if there are any humans left
