Changing text color while writing it one character at a time in a text field.

Hi!

I'm developing a game with a text box based dialogue system, like old jrpgs. I read the dialogue text from file and I write it one character at a time in a text field. If the player clicks a button, the entire line appears instantly.

I'm now trying to give more visual options to the text. I want to color only some words of a sentence. If I change the text field color it obviously works, but it applies the color to the whole field. If I use tags, it works when the whole sentence is written but it doesn't work while the text is showing one chararacter at a time.

I thought I could "read" the tag one character at a time while I'm displaying the text, ignore its characters and apply the color to what comes after it, but I don't know how I could apply the color to that.

How can I refer to some specific part of a text field so that I don't apply the color to the whole field?

This will also help me changing only some words text size.

Thank you in advance!

Luca.
