What method should be used to generate obstacles in CodeHS?

Creating a function that randomly positions new obstacles at intervals is the most effective method for generating dynamic and varied gameplay. This approach allows obstacles to appear at different locations and times, which enhances the game's challenge and keeps the player engaged. By randomizing the spawn location and timing of obstacles, you prevent predictability, encouraging players to stay alert and adapt their strategies.

This method also enables easy scalability; as the game progresses, you can adjust the frequency of obstacles based on difficulty levels or player performance, offering a customized experience. In contrast, using a pre-defined array of positions or manually placing obstacles limits variability and can lead to repetitive gameplay, while relying on a single spawn location can result in a lack of challenge and excitement. Thus, the random positioning method is optimal for creating a compelling game environment.
