Making the code simple
Those of you who can remember back to high school algebra will be able to see
that these formulas can be simplified further by multiplying out and cancelling
terms with opposite signs, resulting in our final clockwise code:
onClipEvent (enterFrame) { //clockwise
framePos = int(_xmouse / 100 * _parent._totalframes);
if (framePos < 0) {
_parent.gotoAndStop(1 - ((framePos + 1) % _parent._totalframes));
} else {
_parent.gotoAndStop(_parent._totalframes - (framePos % _parent._totalframes));
}
}
And applying the same process to our anticlockwise code gives:
onClipEvent (enterFrame) { //anticlockwise
framePos = int(_xmouse / 100 * _parent._totalframes);
if (framePos < 0) {
_parent.gotoAndStop(_parent._totalframes + ((framePos + 1) % _parent._totalframes));
} else {
_parent.gotoAndStop(1 + (framePos % _parent._totalframes));
}
}
This makes it really easy to build an Object VR player for any QTVR movie of
any length by simply grabbing the code that is appropriate for the rotation
of your video file and pasting it on to your driver clip.
Time to wrap things up. Let's have a quick look at how to use our player.
