Looking for Dialogue tutorials that teaches developers to read XML files to the game.

Hi there,

I’m a new into Unity and trying to build a Dialogue system and kinda succeed in a way. But it is primitive and making the game lagging.

Then I was introduced to XML files that a veteran Unity developer recommended, but now I’m stuck and wishes there are some tutorial in XML into Dialogue system-ish.

Please and thanks you.

Sincerely,
