Give an example of using functions to control a sprite's movement in CodeHS.

Utilizing keyPressed() to adjust sprite position based on arrow key inputs is a prime example of using functions to control a sprite's movement in CodeHS. This approach allows for real-time interaction, where the sprite's position is updated dynamically in response to user keyboard inputs.

In this method, the keyPressed() function is triggered when a key is pressed, and within this function, specific conditions can be checked to determine which key was pressed (like the arrow keys). Based on the input, the sprite's position can be altered by modifying its x or y coordinates accordingly. This creates an interactive experience where the user can control the sprite's movement with the keyboard, making the programming of games and animations more engaging and responsive.

The other options, while related to modifying movement or appearance, do not directly involve controlling movement through the keyboard in this interactive manner. Using mouse events may adjust position as well, but it is not as universally applicable for movement controls compared to keyboard functions. Applying CSS properties pertains more to styling than functional movement in the context of sprites. Frame rate adjustments can enhance smoothness in motion, but they do not directly dictate movement mechanics controlled by user inputs.
