What is a common use of functions in animation and game development?

Functions are a key aspect of animation and game development because they allow developers to group code into reusable blocks that can be executed multiple times throughout the program. This is particularly beneficial in both animation and game scenarios, where certain actions or calculations may need to be performed repeatedly, such as moving a character, updating the score, or checking for collisions.

By encapsulating these actions within functions, developers can reduce redundancy, improve code organization, and facilitate easier updates or modifications. For instance, if a character's movement needs to be adjusted, the developer can change the code in one location (the function) rather than searching for and updating every individual instance throughout the program. This leads to more efficient programming practices, making the codebase cleaner and more manageable, which is essential in both animation and game development.
