Depending on your instructor or semester, might have a twist:
Understanding onKeyPress and global state is your first step toward building a playable game in CMU CS Academy—like a simple maze or a "catch the falling objects" game.
CMU CS Academy 6.3.5 exercise "Triforce" in some versions and associated with "Boat in Ball Pool" "DVD Screensaver" in others (depending on the course edition), focuses on using Step Events to create multi-directional animation If you are working on the

In the broader context of the CMU CS Academy CS1 curriculum, Unit 6 typically introduces or advanced Mouse and Keyboard Events . By the time students reach section 6.3.5, they are tasked with combining multiple foundational concepts to solve a complex graphical puzzle. Core Concepts Tested in 6.3.5
def onMousePress(mouseX, mouseY): # This creates a star with 5 points and a radius of 20 # at the (x, y) coordinates of the mouse click. Star(mouseX, mouseY, 20, 5, fill='gold') Use code with caution. Copied to clipboard 1. Identify the Trigger
The boundary check uses 20 and 380 because the radius is 20. The center of a 20px radius circle at x=20 touches the edge at x=0. Depending on your instructor or semester, might have
