Bouncing-Objects

In this assignment, you will build a simulation where turtles move inside a bounded area. When turtles hit the boundary, they will “bounce” off the walls. You will implement two different movement systems:

1. Angle-based movement (heading system)
2. Coordinate-based movement (delta x / delta y system)

You will then extend the first system so that new turtles are created every time a wall is hit, creating a growing simulation.

Starter Requirements

Your program should include:

• A screen setup (black background recommended)
• A playing_area() function that draws the boundary box
• A list to store all turtles in the simulation

Part 1: Playing Area

playing_area()

Create a function that draws a square boundary:

• Size: approximately 480x480
• Centered on the screen
• Use a visible color (teal or similar)
• The boundary should be filled or outlined clearly

Part 2: Movement Using Heading (Angle-Based)

move_with_heading(t, turtles)

Write a function that:

• Moves the turtle forward continuously
• Uses:
  • forward()
  • setheading()
  • heading()

Behavior Requirements:

• The turtle should bounce off walls using reflection
• Use angle reflection logic (like a mirror bounce

Extension Requirement (IMPORTANT) When a turtle hits any wall:

• Create a new turtle
• Give it:
  • Random color
  • A shape
  • Random starting direction
  • Speed of 0
  • Add it to a list of turtles
  • Return the updated list

Movement Using Delta X / Delta Y

move_with_deltas(t, dx, dy)

Write a function that moves a turtle using:

• dx (change in x position)
• dy (change in y position)

Behavior Requirements:

• Update position using:
  • x = x + dx
  • y = y + dy
• Use: 
  • t.goto(newX, newY)

Wall Collision Rules:

• If hitting left or right wall:
  • Reverse dx
• If hitting top or bottom wall:
  • Reverse dy Return Values:
• Return updated (dx, dy)

Main Simulation Loop

Your program should:

• Store turtles in a list:

  turtles = [yertle]]

• Continuously update all turtles:

  • Loop through each turtle
  • Call move_with_heading()

• When new turtles are created:

  • Add them to the list
  • They should immediately begin moving too

Expected Behavior

After completion:

• One turtle starts moving
• It bounces inside the box
• Every time it hits a wall:
  • A new turtle appears
• Over time:
  • The screen fills with many moving turtles
