Hi - wonder if you could please advise? I'm using this script from the AC Wiki. It mostly works but the issue I'm finding is that the text appears where it shouldn't before it's momentarily teleported to the correct place above a player's head. If I just use Text Mesh pro, this issue doesn't occur, so I suspect it's either something with Super Text Mesh, or the script.

Vid to demonstrate:

Script:

using UnityEngine;
using System.Collections;
public class SuperTextFromACSpeech : MonoBehaviour {
    /*
    This script is to make Super Text Mesh work with Adventure Creator.
    Essentially, it lets AC handle all non-text elements (sound effects, user input),
    while letting STM handle all text-related issues (scrolling speed, animations, colors, etc.)
    Simply put this script on a Super Text ui item in your subtitlesUI adventure creator menu,
    then hide the text item that AC thinks it's referencing (put it offscreen, make it invisible, whatever!).
    AC will play dialogue sounds and handle input as normal,
    but the player will only see the Super Text.

    */
    SuperTextMesh supertext;
    AC.Speech speech;
    AC.Dialog dialog;
    void Start () {
        supertext = GetComponent<SuperTextMesh>();
        dialog = FindObjectOfType<AC.Dialog>();
    }
void Update () {
        //If there is dialogue currently being spoken...
        if (dialog.GetLatestSpeech() != null)
        {
            //And you haven't already sampled it...
            if (speech != dialog.GetLatestSpeech())
            {
                //Then set the supertext text to print the dialogue
                speech = dialog.GetLatestSpeech();
                supertext.color = speech.GetColour ();
                supertext.Text = speech.log.fullText;
                //This tells the text to read at regular speeds, in case it was told to speed read
                supertext.RegularRead();
            }
        }
        if (supertext.reading == true)
        {
            if (Input.GetMouseButtonDown(0) || Input.GetKeyDown("space"))
            {
                //If the player clicks or presses space while reading, then speed read
                supertext.SpeedRead();
            }
        }
    }
}

Wonder if any tips to fix it, please? I've tried changing the Canvas Fade to 0, and putting this script higher up in the execution order (and a bunch of other fiddling) but that still doesn't sort it.

I've asked the creator of the script for advice but he says it's so old he wouldn't know whether it's a script issue or an update to Super Text Mesh that'd be causing the glitch.

Not sure if you'd like to update the AC integration script on your side, but for what it's worth this is the adapted script with your suggestion and also this line included, which respects the character's subtitle colour (which I think you suggested adding from some time ago!)

supertext.color = speech.GetColour ();

Perfect! I'm glad it works, I'll just link to your post on the Helper Scripts page!

D'oh, seems I maybe spoke too soon! In the editor, when I play the game, it seems fine, but as soon as I try and record with Unity's recorder, I can see the quick movement before the text gets moved into place. I've tried your other suggestions, and wondered if I could please try that script you suggested that helps with the ContentSizeFitter?

Re your other question,  on the object that has Super Text Mesh on for subtitles, I also have a 'Text Mesh Pro' object on it too that's hidden as it's the only way I can get Adventure Creator's menu to accept the 'linked text' object, as it's looking for a TMP component.

Example of what's happening with recorder:
