How do I : Create a scrolling text?

Hello everyone,

I am not sure what the proper term for this is, but I am trying to make a dialogue box that functions in the same way as the old Pokemon games.

I have a hidden text box that appears when the player sprite is close to an NPC sprite, displaying set text depending on the situation. But the text appears all at once. I would like it to appear gradually like in classic RPGs, but I am not sure how to do this.

Here is a video to illustrate what I would like the end result to be:

Thank you for your time!

I think you mean the typewriter effect, there's an example for that in the FAQ..

Using the search you will find more examples..

Ah, lovely, thank you.

I assumed it would be rather simple once I knew the proper name for the feature!
