transform.position assign attempt for "owl" is not valid. Input position is...

Unity Engine

So I got this error that I couldn’t fix :slight_smile: Wasted a week or so googling and haven’t found anything useful to my problem. I am following this tutorial

. The code I wrote is absolutely correct, I checked way too many times. It has something to do with unity. Please, help :wink:

“So I got this error that I couldn’t fix”

What error - care to share it here? Or is it the “transform.position assign attempt for “owl” is not valid”. Either way, context is unclear.

“It has something to do with unity.”

I somehow think you just have some error. If author of this tutorial got it working, you should too -

“The code I wrote is absolutely correct”

But it doesn’t work? I think you should post your code…

That’s the error I get when I press play
transform.position assign attempt for ‘Armature_Flying_2 (5)’ is not valid. Input position is { NaN, NaN, 0.000000 }.
UnityEngine.Transform:set_position(Vector3)
RandomPatrol:Update() (at Assets/RandomPatrol.cs:37)

This is your answer that you already had in the error message itself. You’re assigning a Vector3 where the X & Y are NaN (not a number). These can be created for various reasons but most llikely as a result of a math operation doing a divide by zero; something you can easily find more information about with a quick search.
