// Procedure Name:
//
// reverseKeys;
//
// Description:
// This simple script reverses keyframes of all objects below in a heiarchy
// Be careful when using this script with objects with any set driven Keys
// because it will reverse them as well.
//
// Usage:
// user must enter the first and last of the frames to be scaled
// usually this will be the last keyframe of the objects selected.
// eg. reverseKeys(1,200);
//
// Limitations:
// any keyframes outside the range of keyframes entered will not be scaled
// and could result in unpredictable animation behavior. Best when used with
// an entire range of keyframes.
//

global proc reverseKeys (int $firstkey, int $lastkey)
{

int $lastkey;
float $mediankey;
$mediankey = ($firstkey + $lastkey)/2;
//calculates the pivotpoint of the keys to be scaled
selectKey -hi below;
scaleKey -timeScale -1 -timePivot $mediankey;
}
