Apologies for the very late reply!

The system is composed of "DialogueManager.cs" (handles typewriter effect, advancing lines, freezing player) and "DialogueData.cs" (ScriptableObject to store lines + portrait per conversation).

So it is done entirely in code, no animation needed. I believe it is called "typewriter effect". I use IEnumerator:

private IEnumerator TypeLine(DialogueData.DialogueLine line)
{
    isTyping = true;
    dialogueText.text = "";
    foreach (char c in line.text)
    {
        dialogueText.text += c; // this will add one character at a time
        yield return new WaitForSeconds(typeSpeed); // this will wait between each character
    }
    isTyping = false;
}

It loops through every character in the string one by one, adds it to the text, then waits a tiny amount of time before the next one..

The press space to complete instantly part is just:

if (Input.GetKeyDown(advanceKey))
{
    if (isTyping)
        SkipTypewriter();
}
private void SkipTypewriter()
{
    StopCoroutine(typeCoroutine);
    dialogueText.text = currentDialogue.lines[currentLineIndex].text; // this will show the line all at once
    isTyping = false;
}

Let me know if this helps :)
