I've been trying to figure out how to get Super Text Mesh and Adventure Creator to play nicely together, and I've made a script that does just that!
Essentially, it uses AC for audio, user input, etc., but lets STM handle all text-specific items, like scrolling speed, animated letters, and colors.
It does this by running AC's normal text system offscreen, while STM directly samples the dialogue being written from the Dialog manager.
I hope this helps anyone interested in using both tools. :)
