I'm using SetTweenTextAlpha to fade out text , but as a result it's leaving quite a few completely transparent (0 opacity) text objects. How much does this impact performance, particularly on mobile devices? Is there an easy way to delete the text objects after they've faded out, or at least a way to identify when a tween ends without explicitly providing the textID?

You could add the IDs to an array with the time that they can be deleted.

It's a good idea to track all of your entities in an array anyway, then adding a tween expiry parameter would be quite easy.

So when I try to implement it in the code below, my program crashes. It still creates the text objects fine, and I'm able to verify that it does exist, but the call to DeleteText always crashes it.


And here's where I create it, but like I said, it's creating them fine. It's just trying to delete them that causes the crash.


That's it so far as interactions with the text objects go. Am I missing something or doing something wrong? I was able to get the sample code on the command page to run, just can't figure out why or where it goes wrong with mine.

What is the error when it crashes? The only I see that could fail is that your array index (ShotText.NextToDelete) is out of bounds.

I just get a generic "This program has stopped working" message. Another point of confusion is that it breaks as soon as I create the text, even though I'm using the if statement to check the deletetimer.

I fixed it, the problem was that I used > when I needed to use <, so I was attempting to delete text before Sync() was called after the CreateText. I blame staying up too late.
