Zombie Attack Simulator

So, after binging on "World War Z 🧟‍♂️", it hit me like a zombie apocalypse idea:

  • Imagine if the scientists called me instead of Brad Pitt to save the world with simulations!
  • I thought, why not create a simulation, making it useful and entertaining?
  • Let's plot the crazy results on a graph, so we can have some fun visuals and even save them in a CSV file!
  • But beware, the zombies might not be thrilled about this simulation invasion!

Demo

Assumptions

I formulated some guidelines before implementing this simulation.

General

  • We will have Humans, Vampires, Water, Garlic, and Food on a 2D map
  • Humans and vampires will move with each timestamp and interact with each other
  • Humans can live past 70 timestamps and will get killed
  • Starting health of a human will be 100 and that of a zombie will be 50
  • Most of the parameters can be modified inside constants.py file, i.e. how many steps they can take at a time

Interactions

  • If humans interact, there is a 40% chance that they will help each other and a 60% that one of them will kill the other for health
  • If humans interact with edibles, their health increases by water 50, food 30, and garlic 100
  • If humans interact with vampires, there is a 70% chance that the human will become a vampire and a 30% chance that the vampire will get killed
  • If vampires interact with each other, both of them will lose 20 health

Execution

Ensure that you have python3 and pip installed. For ease of use, I am managing the execution via Makefile, however, you can run the program directly as well. Navigate to the code directory:

  • make install: Creates a venv, activate it, and install requirements.txt
  • make sweep: This will execute the program in sweep mode, we will discuss this later
  • make run ARGS="{initial_humans} {initial_vampires} {total_timestamps}": This is manual mode, more details are given below
  • make clean: This will delete __pycache__ and Simulation Results directories

Manual Mode

This will run the simulation according to the command line arguments, i.e. make run ARGS="7 2 20". In this simulation, there are:

  • 7 humans, 2 vampires at the start, and the simulation will run for 20 timestamps
  • Every interaction will be logged on the terminal
  • Results will be saved in the Simulation Results directory with this format Timestep_{timestep_number}.png

Sweep Mode

Just run make sweep and see the magic happens. The simulation will run for all combinations of humans and vampires as per the SWEEP_MODE_PARAMS variable inside constants.py for the given number of timestamps.

  • Final plot will be saved in this format {sweep_{sweep_count}_h_{total_humans}_v_{total_vampires}
  • results.csv will have the remaining humans and vampires count, something like this
