Thanks for the oldschool TV reference! That show was epic lol….for that I will help you a little
I actually kind of wanted to do something like this for an old game that never really left the drawing board (yet, lol). Except it would be from the side, it would still look and be created in the same sense, I imagine
What you are probably going to need is a procedurally generating source bitmapData for the tunnel, and a dirty blitting system to draw that ‘downwards’ or whatever direction you wanted (i.e. rotated then drawn) with gradual deviation. Add onto that a blur filter and some cosmetic, individually moving particle effects ‘bled’ onto it and you should end up with something fairly impressive.
However it may or may not be a lot of work depending on how much you are going to use it and if you even know what I’m talking about…
