Coroutines and loading screens
So i have a simple issue.
I'm executing a large block of code within a coroutine. Simple example:
IEnumerator perform_async()
{
LoadingScreen.SetActive(true);
yield return null;
// call heavy function here which takes a while to complete
LoadingScreen.SetActive(false);
}
In this example, LoadingScreen is a unity UI object so in order for it to become visible before the big function executes, i have to return null once so it appears.
.
Now let's say that this LoadingScreen has a text log on it. I can call a function, AddLogTextLine, which creates a new UI text block and appends it to the log. The problem is, if i do this, the log items don't become visible until after the heavy function ends.
.
When the AddLogTextLine function is called, I tried making it create the text object within a coroutine (so it would be a nested coroutine) but that doesn't seem to help. How can i add log items to the loading screen from the heavy function and have them appear at the same time they are created?
You may try break apart your large function and return null after every part
