Select Sprite for visibility from code

I'm sure this has already been answered somewhere in the forums, but I can't seem to find an answer that makes sense. I'm new to Construct 2 and coming from using Flash, so I might not be thinking about this the right way.

The project is to build a simple Hangman game, so no enemies, or collision, just logic.

I have a function that creates the letters of the word from XML data as invisible sprites and places them in a line an the stage. Easy enough. Then as the user selects letters if the letter exists in the string, it reveals that letter.

If I were doing this in Flash I would create an array and put the letter sprites in that array. Then I loop through a find(string) and use the return to make that position in the array visible.

It's that last step that I can't figure out. I don't know how to use the find return to target a specific sprite to reveal that letter.

Thank you. I see how you set the value in the instance and then check that value against the function param. I assume that means that when the program gets to step 9, that it checks all the instances of LetterDisplay. I think that's the part I'm having trouble conceptualizing. In Flash you have to target an instance specifically with dot syntax.

Yeah, C2 always check all instances and pick only the ones that met the condition.

Btw, on this forum, type "@my name" (eg: 7Soul) so I get a notification that you replied to me

— Will do. Thanks for the help. I feel like a displaced refugee of the Apple and Adobe Flash wars. I hope Construct 2 can become my new home.
