Lab Overview

We were to remix the boom-bust code that Mr. Davis created and track the number of each species in two lists. The foxes stayed somewhat constant, but the bunnies had a varying number almost the entire simulation. We had to upload the lists to Google Sheets or Excel and graph the sets of values. For the gremlin game, we were to code a cloud dropping raindrops and make the gremlin shrink and duplicate. If the player misses 10 droplets, it is game over!

My Solution

For the list in the boom-bust game, I created a list that will add the number of foxes and bunnies to each list every second. I exported both lists into Google Sheets and created 3 graphs based on 3 different simulations. For the gremlin game, I made the creature follow the pointer at the line y=-100. If the creature touches a snowflake, it shrinks and duplicates itself with creations of clones. The snowflakes make clones and go to the cloud bouncing across the screen and fall until it reaches the edge. If the player misses 10 snowflakes, the game is over.

Questions

  1. The volume of the foxes and rabbits changes depending on the "fox death rate" and "rabbit death rate." If there are a ton of foxes, the bunnies decrease a lot, and the foxes fade. If there are few foxes, the bunnies increase, and the foxes start popping up again.
  2. No, because the number of each species is picked at random by the computer within certain guidelines. The data may be similar in the rate of increase and decrease in numbers of each species.
