Look rotation viewing vector is zero

[skyboard]

It seems I am getting lots of Console messages (60 a sec or so) 

Look rotation viewing vector is zero
UnityEngine.Quaternion:LookRotation(Vector3, Vector3)
FluffyUnderware.Curvy.Controllers.CurvyController:InitializedApplyDeltaTime(Single) (at Assets/Plugins/Curvy/Controllers/CurvyController.cs:874)

FluffyUnderware.Curvy.Controllers.CurvyController:FixedUpdate() (at Assets/Plugins/Curvy/Controllers/CurvyController.cs:749)


I have also a issue where I can't get my 2D sprite to look at the current heading location...  tricky stuff.



I hope I get these issues fixed.. I was thinking of having a ghost item infront of the plane and have it jump a couple CP's ahead of the plane and use a lookat routine..

Update (next session later):

I managed to get some headway on the orientation of my 2D sprite.

Hi,
About the console messages, did you by any chance set the controller's orientation to use the spline's orientation on a spline with no orientation? If not, could you send me please your controller's Orientation settings?
About the remaining of your post, I think I answered it in your other thread, right?
Have a nice day

I got this message too.

From Console:

First it showed that bubbling from curvyGenerator.Refresh(); but then i deleted that code. Again same message.

That message appears when CP[Last] and CP[Last-1] have same values of Transform.

That  message appears when CP[Last] and CP[Last-1] have same values of Transform.

So this means that the last segment is empty. Is there any reason for you to have an empty segment?

What do you mean with "Empty Segment"?

[_Aka_]

A segment is the part of the spline between two consecutive control points. By empty segment, I meant a segment of length 0. In other words the two control points delimiting the segment have the same position.
