Instructions

This exercise helps you practice refactoring your code to simplify functionality.

Please complete the following:

1. Continuing from the file built in the code tutorial on arrays you will be creating a revised updateStars() function to allow it to directly change how the stars are drawn using arguments provided with the function.
2. Read through the documentation on functions in p5.js, pay attention to how you can provide a function with input (aka. arguments) to pass values along to inside the function.
3. Comment out the original updateStars() function and create a new updateStarsN(star_number) function that will take the number of the star from the array to update.
4. Simplify the original updateStars() function in the new updateStarsN() function using the star_number argument/variable to select which star is being updated. For example if calling on the variable in the updateStarsN() function we would likely use something like stars[star_number[0] = ...]
5. Change the use of updateStars() to the new updateStarsN() function within the draw() function to update the movement of each of the stars.
6. Run the sketch using the play symbol to ensure the output is as you expect.
7. Save the sketch to your computer.

Exercise rules

Please note the rules for exercises in this course:

• AI use is not permitted for code exercises. These are your opportunity to practice some of the basics we will need to progress through the course.
• You can use other online resources, course materials, and lab-mates for support. This being said, others are not allowed to do your work for you. Also, if you are drawing from online resources, course materials, or peers, you must cite it.
• Cite any knowledge that is not yours in a comment in the code. The internet is a huge repository of information and you are welcome to use it, but you must let us know when something does not originate from your own knowledge.
• If work has been copied without citation the exercise grade will be zero. Please make sure to include comments indicating where you had assistance or learned.
