How do I make the real text appear as the player type?

So I have a bubble chat that has the real text hidden, and I want to give the player the option to press randomly on the keyboard and the real text appear one by one. But how do I do that?

Are these variables global or private to Bubbletext? Because if they are private to Bubbletext then Set text won't recognize them, and if they are global then BubbleText Set to left(t,index) doesn't really do anything.

These variables can be global or instance on BubbleText object. Or even local+static.

The code should work, if it doesn't please post a screenshot of your events, or share your project file.

Thanks for replying! Here's the file.

You need to use either global variables, or instance, not both.

If you are using instance variables, then change the expression to left(Self.t, Self.index)

Hey! Thank you so much. I finally got it to work.

For anyone who come later, this is what I did:

Add these two instance variables to BubbleText:

String Variable t=Content of the text

Number Variable index=0

On any key pressed:

BubbleText -> Add 1 to index

BubbleText -> Set text to left(Self.t, Self.index)
