How can you create an enemy sprite that moves randomly?

To create an enemy sprite that moves randomly, utilizing a function that changes its movement direction periodically is an effective approach. The randomDirection function alters the sprite's direction at set intervals, allowing it to move in various directions without following a predictable path. This randomness is crucial for creating challenging gameplay, as it prevents players from easily predicting the enemy's next move, thus enhancing the game’s dynamics.

Changing the enemy's direction frequently creates an impression of erratic behavior, which is a common tactic in game design to make opponents more engaging. Players find it more difficult to predict and avoid such enemies, adding to the excitement and challenge within the game.

While other options like calling the moveRandom method or using multiple conditions might seem viable, they either lack the simplicity and effectiveness of automatically changing direction or add unnecessary complexity. The focus here is on a clear, straightforward method to achieve the desired randomness in enemy movement.
