Re: FCurve.AddKey()

["Christopher Crouzet" <christopher.crouzet(at)gmail.com>]

It looks like that the 'AddKey' function don't work as expected when applied to newly created FCurves.
Instead, you could use the 'SetKeys' function which works fine.

Here is a quick example:

FCurve fcurve;
param.AddFCurve(siStandardFCurve, fcurve);

LONG nKeys = 2;
CTimeArray timeArray(nKeys);
CDoubleArray valueArray(nKeys);
CLongArray keyInterpArray(nKeys);
CTimeArray leftTanXArray(nKeys);
CDoubleArray leftTanYArray(nKeys);
CTimeArray rightTanXArray(nKeys);
CDoubleArray rightTanYArray(nKeys);

timeArray[0] = 0.0;    valueArray[0] = 0.0;    keyInterpArray[0] = siDefaultKeyInterpolation;
leftTanXArray[0] = 0.0; leftTanYArray[0] = 0.0; rightTanXArray[0] = 0.3; rightTanYArray[0] = 0.5;

timeArray[1] = 1.0;    valueArray[1] = 1.0;    keyInterpArray[1] = siDefaultKeyInterpolation;
leftTanXArray[1] = - 0.5; leftTanYArray[1] = 0.0; rightTanXArray[1] = 0.3; rightTanYArray[1] = 0.0;

fcurve.SetKeys(timeArray, valueArray, keyInterpArray, leftTanXArray, leftTanYArray, rightTanXArray, rightTanYArray, false);
