If the person moves off the screen, you need code to reset them to the beginning or reverse their path. Common Pitfalls and Solutions
If you are moving a complex character, ensure all parts are in a single Group . If you only move one part, the stick figure will "fall apart" as it moves. Why This Lesson Matters
Ensure your stick person group and a counter (like cartwheelCounter ) are defined outside the onStep function. 6.3.5 Cmu Cs Academy
In the "Continuous Cartwheels" version (6.3.5), the objective is to make a stick person move horizontally while rotating.
Example: if (icon.right >= 400 or icon.left <= 0): icon.dx *= -1 . If the person moves off the screen, you
The exercise is designed to test your understanding of how to update object properties continuously.
Master 6.3.5 CMU CS Academy: A Guide to Procedural Motion refers to a critical exercise in Unit 6 of the CS1 curriculum titled " Continuous Cartwheels " or variations like " Triforce " and " DVD Screensaver ," depending on the version of the course. This lesson focuses on procedural animation , requiring students to move and rotate graphical objects simultaneously using the onStep() function. Overview of the 6.3.5 Challenge Why This Lesson Matters Ensure your stick person
Unit 6 is a turning point in the CMU CS Academy curriculum. It shifts from static drawings to . Mastering 6.3.5 proves you can handle multiple variables changing at once—a fundamental skill for game development and advanced simulation.
This function runs automatically multiple times per second. You must update the centerX and rotateAngle of your person here. person.centerX += 5 (moves the person right) person.rotateAngle += 10 (rotates the person)
Successfully animate a group of shapes (like a stick figure or a "DVD" icon) so they move across the canvas while rotating or bouncing off edges.
