The code below works as I'd expect, Bernard. One key added at frame one,
value 1.0 the next at frame 25, value 10.
oFcurve = selection(0).posx.source;
var oFcurveKeys = new Array( 1,0,25,10 )
oFcurve.beginedit();
iLength = oFcurveKeys.length;
for( i = 0; i < iLength; i=i+2 ) {
fTime = oFcurveKeys[i];
fValue = oFcurveKeys[i+1];
oFcurve.addkey( fTime, fValue, 0, true );
}
oFcurve.endedit();
