After laying the groundwork in our previous article on the basics of Unity's coroutines, we're now ready to delve deeper into the mechanics that drive coroutine execution. This article aims to explore two key aspects that make coroutines a powerful tool in Unity: the concept of yielding and the coroutine's relationship with Unity's main game loop.
Yielding is a cornerstone of coroutine functionality, allowing a coroutine to pause its execution and yield control to other routines. This feature enables you to write asynchronous code that can wait for specific conditions to be met, such as time delays or external data, before resuming its execution. We'll explore the different types of yield statements available in Unity, like yield return null and yield return new WaitForSeconds(), and discuss their implications on coroutine behavior.
