How to find first empty text box?

There’s an issue with the top events. The shuffle array event and the event after it should be nested under the At beginning of scene. Follow the screenshot I sent you earlier in the other thread:

Summary

Random letters with password ones - #6 by insein

.

Also this event:

It should be a different object and not PassObj. Follow what I suggested earlier.

Summary

This requires object variables to set IDs for the RandomLetters and PassObj objects. Set IDs to the RandomLetters to be the same as the index of the “Letters” array. And when you click to choose a random letter, pass this ID to the PassObj. So that you’ll know which RandomLetters object to show/hide when returning a letter back.
