Hi Derek, Sorry for the late reply, this post got buried under a lot of email.
Thanks for the explanation, it makes everything a lot clearer. I've read the article about FSCommand. My approach to this bug would be to build a class that stores methods and calls them in an interval (20ms ?). Anyway, it's clear now that I can't make use of SetVariable for the massive amount of data that our driving simulator is sending to the Flash interface I built (with a lot of shiny dials and buttons that resemble the dashboard of the car, and reflect the current state that the car is in: speed, revs, steering wheel position, gear etc.). I guess I'll have to talk with the programmer responsible for the sending side of the data to chop up the data in chunks and make him send it in an interval via EI. Perhaps I could even program an extrapolating algorithm that positions the dial of the speedometer fluently. If you have any other ideas, please let me know.
