Will UnityEvent wait for completion of listeners ?

Hi all,

I am using the UnityEvent EventManager script from this post in one of my games.

I want to know if Unity waits for all the listeners to finish their function before moving on to the next line ?

For example,

If I have a method somewhere in my code that contains:

 EventManager.Invoke("MyFirstEvent");
 EventManager.Invoke("MySecondEvent");

Will MySecondEvent be invoked only after all the listeners of MyFirstEvent have finished ?

The reason being that I perform an operation in one of the listeners of MyFirstEvent which is needed for an operation performed in MySecondEvent.

Alternatively am I best to use a coroutine and call the MyFirstEvent on the first frame and MySecondEvent on the following one just to be sure.

Thanks
