Yes, I understood that far- perhaps I wasn't clear. When you press spacebar, the dialogue continues to the next line, but if you press space bar early, it skips the writing step. I want to split the functionality between that continue button and the skip feature into two different buttons, for instance, I could press "A" to continue the dialogue to the next line. But if I wanted to skip through the dialogue I want to press "B" instead of "A." Currently its a one button fits both situations, with the space key.
As for AudioStream, that worked! There's only one bug with this that I can see; the stream isn't set back to a default if stream file is null, so if null, the speaker will have the same voice as the last speaker. I'm looking into now
