Dynamic changing Marquee/Ticker?

I’m trying to create a real-time twitter scroll. I can not figure out how to update the TextTOP for a smooth transition to a new tweet. I am using a FIFO to send to the TextTOP, and when the new text is sent, it overwrites immediately regardless of where the text is scrolling.

I’d like to append the “new” text to the end of the current text being rendered. I was thinking about adding the “new” text into the Post Text but it also just overwrites rather than appends.

I have read to grab multiple and merge them for a longer scroll, but then at the end there would be the same issue of the new text “popping” in rather than coming in at the end of the scroll.

I’m looking at the InfoCHOP to see if I can find a value that will tell when exactly when the current text is about to Loop/repeat, so I can time the next text to be changed before it loops back, but nothing looks like that info.

Is my logic going at this all wrong?

Thanks, RB
