How do I let the script wait a predetermined time?

Question

Firstly, I have really looked up my problem for a long time. And I have also tried a lot of different possibilities. Yet, I still didn't get my code running. Please do not refer to other Threads. I most likely have already read them.

So, for my problem. I tried to let the script wait until an animation has finished playing but somehow the two timestamps I created always show the same Time.

 void OnTriggerExit2D(Collider2D other) {
         //print(Time.time);
         StartCoroutine(WaitForFalling());
         //print(Time.time);
 }
 private IEnumerator WaitForFalling() {
     yield return new WaitForSeconds(1);
 }

Thank you very much for looking through my code and for your time.

The reason for this behaviour is as follows:

The StartCoroutine in OnTriggerExit just starts a coroutine but does NOT wait for the coroutine to finish! It does not matter that you put a yield in the coroutine itself. The OnTriggerExit is just a normal function, therefore it just continues with the next instruction. In order to achieve what you want I suggest to trigger a coroutine in OnTriggerExit like you did, but to write the whole behaviour in this coroutine, e.g.:

 void OnTriggerExit2D(Collider2D other)
 {
    StartCoroutine(DoSomething(other));
 }

 IEnumerator DoSomething(Collider2D other)
 {
    float timeToWait = 1f;
    yield return new WaitForSeconds(timeToWait);
    // Proceed your code here...
 }
