locking vertical orientation/alignment

[BenStorch]

Hi,

I tried all the orientation options but am struggling to find the right setting.

I have a flying machine following a spline, and I want it to align with the spline
tangent in the x z plane, but I need to lock the y orientation.

I hope that's straightforward ?

Thanks,
Ben

Hi
Right now controllers can't follow a path only on specific translation/rotation dimensions. That's a feature that I am planning to include in the next major update. Until then, you can implement a solution to your specific use case by inheriting from the Spline Controller class. Override the ComputeTargetPositionAndRotation method by making sure the computed up vector is ignored and replaced by the locked y direction you want. Do you see what I mean?

Thank you for your reply !

I just had a look into the controller script, and found it starting at line 537 -
but I am pretty new to coding so might take me a while to find the 
lines that I would have to change and how, but will try.

The reason for wanting to constrain the vertical orientation is that the machine takes off quite steeply, 
which tilts it and is a bit uncomfortable when you are inside in VR!
