Moving to the left of the image

Now it's not really working when it goes below 0, so we need to adjust our formula when the mouse pointer moves to the left of our box. Our first problem is that as we are moving to the left our range is starting at -1, and we would like it to start at 0. (It actually does start at 0, but unfortunately it overlaps with the code we have already written: that's where the funkiness is creeping in.)

To correct this, we need to add 1 to our _xmouse calculation before we perform the modulo. That gets us closer to what we want, but we still have negative numbers. Since we don't have any negative frames, we finally need to correct this by adding 36.

This may be seen in the following table (the red area shows the bit that we already have working, the grey areas show where the 36 frames to the left of the box are repeating):

Once again, you can try them out in a trace ActionScript statement to see how they perform as you move your mouse left of the QTVR movie. And this is the code to spin the movie:

onClipEvent (enterFrame) {
     _parent.gotoAndStop(36 + ((int(_xmouse / 100 * 36)+ 1) % 36));
}
