How to wait until coroutine inside of nested function is complete?

[obtuse hull]

Hi, I have FunctionA() and FunctionB().

FunctionA has a coroutine inside of it that gets called. It's a for loop with a yield return new WaitForSeconds() at the end of each loop. During each loop, FunctionB is as such GameObject[] objs = FunctionB(). FunctionB has another coroutine inside of it using a for loop.

How can I wait for FunctionB to complete before continuing with the rest of the loop within FunctionA?

Do you mean that FunctionA and FunctionB are coroutines, which return IEnumerator?

That doesn't match what you're describing here, so probably not

If so, then you cannot make either function "wait" for a coroutine to finish

this would freeze the game

if, within a coroutine, you yield a coroutine/ienumerator, it waits for that subcoroutine to finish before continuing. that's the only way to realistically "wait for" it to be done

yeah, something like

IEnumerator Foo() {
  yield return Bar();
  Debug.Log("Done");
}

IEnumerator Bar() {
  yield return new WaitForSeconds(1f);
}

there's a different way to "wait" that.. i don't think is super useful, but i'm not sure what your current set up is

If FunctionA is not a coroutine it can't wait for anything.

I need to point out that if you want to await the result from FunctionB then async is the better solution
Though this depends on your skill level
