Any thoughts on this?

I've recently done something similar and used the SplineHelp class to do it. In my case I wanted to know the actual global position in the 3D world represented by a given percentage along a spline. The SplineHelp::GetPosition() function works fine for that.
If you needed to know the nearest point in the spline to the percentage distance, you could try SplineHelp::GetPointIndex().
Hope that helps a little.

Thanks Steve! I'll check those functions out when I get home. I wish I had a portable SDK on my iPhone. Lol

Hmmm.. well, that works like it's supposed to just like GetSplinePoint() but I sitll get random flickers back to the beginning of the spline. This is weird. It must be earlier in the chain before I build the spline. Back to the drawing board,.

Is this a spline with more than one segment by any chance? I had trouble getting my code to work with segments other than the first one. Gave up in the end, it wasn't critical.

Yes it has more than one. Unfortunately it is critical in my setup. Lol
Thanks again Steve.

Okay, when the object jumps back to the base of the spline, the console prints out the value of the vector created by SplineHelp::GetPosition() as
Vector(-1.#QO, -1.#QO, -1.#QO);
Any idea what that means?
Thanks,
Shawn

The problem is clearly the use of more than one sesgment. I couldn't fix this, maybe someone with more knowledge could show how to make it work?
That strange printout, I can only guess that it's a value incredibly close to zero without actually being zero - like you see sometimes in Visual Studio, it appears to give a really weird value for a Real but you realise that it's just an arithmetical rounding error and it's really zero.

I had some problems with SplineHelp, too, in the past. Therefore, I returned to using SplineObject::GetSplinePoint().

Hi Jack,
Interestingly I get the same results with GetSplinePoint(), You had your object along the spline return to the start? How did you resolve this?
Thanks,
Shawn
