WaitForSeconds

WaitForSeconds is a common function or coroutine used in game development, particularly within the Unity game engine, to pause script execution for a specified duration. It allows developers to introduce delays in their game logic without freezing the entire application. This is crucial for creating a smooth and responsive user experience.

When WaitForSeconds is called, the script or coroutine it is part of will cease its execution for the given number of seconds. After the specified time has elapsed, the execution resumes from where it left off. This is typically achieved using a coroutine in Unity, which is a function that can pause its execution and return control to Unity, but continue where it left off the next frame.

The primary use cases for WaitForSeconds include implementing timed events, creating animations with delays, controlling the pace of enemy behavior, and synchronizing actions within the game. For example, a developer might use WaitForSeconds to make an enemy wait for a few seconds before attacking, or to delay the appearance of a visual effect. It is an essential tool for managing time-based sequences and making game interactions feel natural and deliberate. The function requires a floating-point number representing the duration of the delay in seconds.
