Unity Issue Tracker - Transform.position() values becomes to NaN when one GameObject rotates while colliding the edge of another GameObject

Postponed means that the issue was either a feature request or something that requires major refactoring on our side. Since that makes the issue not actionable in the close future we choose to close it as Postponed and add it on our internal roadmaps and technical debt pages instead.

Transform.position() values becomes to NaN when one GameObject rotates while colliding the edge of another GameObject

Priority: 4Not yet prioritized for a release

Severity: 2No workaround

To reproduce:
1. Open repro project
2. Play scene
3. Using arrow keys (or w,a,s,d) move cube to the corner of ground

Expected: when cube('player' game object) collides with 'ground' corner, player's position values should not be set to NaN

Regression started in 5.5

Reproduced on: 5.5.0a6, 5.5.2p1, 5.6.0b11, f1, 2017.1.0a3
Not reproduced on: 5.4.4p3

FYI, I can confirm that this error still occurs in 2018.2.0b8

I just noticed this issue in 2017.3.1, only in the builds (not in the editor).

Solution was easy. Simply disable PCM in PhysicsManager!

I HAVE THE SAME ISSUE, DO SOMEONE FIND THE SOLUTION?, I HAVE THE NEW VERSION OF UNITY ON 2018

Yes! Finally I found a solution. if(float.IsNaN(transform.position.x)) Destroy(rigidbody); and then just recreate it in next FixedUpdate.

Error appears only when I respawn my car and it gets inside another car. I don't see any solution. It was good in Unity 5.3.6 but I cannot revert back to it from Unity 5.6.4.

I get same error sometimes when trying to rotate car in 5.6.0f3.
I receive Vector3 via network, then check if it is NaN:
if(float.IsInfinity(rot.x) || float.IsInfinity(rot.y) || float.IsInfinity(rot.z))
{
return;
}
Quaternion newrot = Quaternion.Euler(rot);
transform.localRotation = newrot;

Crashes, freeze my game very often. Without this everything would be perfect.

Is there any source of info we can follow for updates or roadmaps on this issue? It's severely impacting my game and (sounds like) many others'.

This needs to be addressed now along with other Rigidbody related bugs like the

INVALID PARAMETER POS IN RIGIDBODY.TRANSFORMCHANGED BECAUSE IT WAS INFINITY OR NAN

and

Infinity or nan floating point numbers appear when calculating the transform matrix for a collider

Our game is released on Steam and the customers and not happy!
