You're right.
Right now, it only goes one direction (from right to left

) regardless of how the player is turned.
I've been thinking about an advanced system that would detect the direction the player is facing, but that will have to wait.
It would require more condition and thus more lines, so I would have to up it to 3 or 4 scripts then.
Unfortuneately, I do not have the time to work on the advanced part, so this will have to do for now.
This effect will work fine for the shots I need for my movie, so once it is done I am moving on to the next sequence.
When the movie is finished, then I may come back and expand this, but the AppGameKit project I have planned will probably bump it back a bit.
I have 64 frames complete now (50%!), and I will work on the rest later this evening.
I want to wrap this effect up before I have to go to work tomorrow.
There should be an extra surprise for this effect, but I won't say what it is until I am done and have made sure it works right.
EDIT
Well, I'm the one who got a surprise.(see attached)
After 128 frames I realized that getting in a hurry when getting rid of the seam was a big mistake.
I skipped a step in the process and messed it all up.

Oh well, back to the drawing board.
It did work out to about 18.5 seconds, so I can still use these for short shots.
I need to start over though to get it right for a proper gameplay loop.
However, at this point I agree with Ched80 that the effect is not that great in gameplay anyway, since it is directional limited.
