I'm looking for a generic / reusable way to wait for coroutines and asynchronous operations to finish in Unity 5, similiar to C#5's await keyword.
The simplest way I can think of is something like this:
public class SomeUtility {
public bool IsDoingSomething { get; private set; }
public IEnumerator DoSomethingAsync() {
IsDoingSomething = true;
yield return new WaitForSeconds(2);
IsDoingSomething = false;
}
}
and then in another coroutine:
while(!someUtilityInstance.IsDoingSomething)
yield return null;
However this is not very nice because it clutters the code with while statements, is not reusable (needs instances and dedicated classes even for simple utility functions!) and a lot of singleton or static stuff where it's not even needed.
The closest I found is using Unity's AsyncOperation. This here works very nicely:
public static IEnumerator Await(this AsyncOperation operation) {
while(!operation.isDone)
yield return operation;
}
yield return SceneManager.LoadLevelAsync("blaaaah").Await();
However.. the problem is: How to create an AsyncOperation? A few services, for examples SceneManager are using it, but the documentation completely lacks anything about creating custom operations or wrapping existing coroutines etc.
So, is there a way to create a simple, generic and resuable "await" for custom coroutines?
