Argument out of range (index) error on DistanceToTF

[t3db0t]

Hi all, I've got a pretty simple setup: a single spline linked to a script, where at Start() I need to analyze the curvature of the spline, so I do:

Code:

float tf = 0f;
float distance = 0.0f;
while(tf < 1){
    tf = spline.DistanceToTF(distance);
    ...
}

Even though the Spline is correctly linked and instantiated, I get:

Code:

ArgumentOutOfRangeException: Argument is out of range.
Parameter name: index

At line 519 of CurvySpline.cs, where DistanceToSegment gets mSegment[0].  An mSegment.Count before that line returns 0.  Not sure what to try next.

There definitely seems to be a delay before you can access the spline for some reason.  If I stick

Code:

Debug.Log(spline.TFToSegment(0f));

into an Update(), the first one gives a NullReferenceException but all subsequent ones work.  How should we work around this?

Ah. Just discovered  CurvySpline.IsInitialized.  My bad.
