Code Toolkit: Python, Spring 2025

Week 6 — Homework assignment

due: Thur, March 5, 8pm

0. Review the class notes for this week.

1. Expand on the in-class example to create a herd of "creatures".

   Start with the last code snippet from the class notes (labeled "Homework starting point") which has a list for y values and draws 10 rectangles.

   Add additional lists for the size and color of each square, and at least one more list used to that modify how the squares are drawn or how they behave. You could use these for the x and y direction so that each square has a direction and bounces off walls or each other.

   Can you make this interactive? Try adding a mousePressed() block, and inside check if the user has clicked on a creature (maybe use dist()). If so, change some property of that creature so it looks different.

2. Do something similar to above but start with nothing on the screen, and add one each time the user clicks the mouse or presses a key. Start with the above code or start fresh, but if you are using the above, Save As and rename it as part 2. You would create lists as above, but leave them empty. And then inside the keyPressed() or mousePressed() blocks, you would append() new values to the various lists. And make sure to use len() in your loops when drawing or moving the objects.
