^ Repeating each frame on Unity 2021.3.24f1. Code in FixedUpdate: ```cs DrawPhysics2D.CapsuleCast( origin: Rb2D.position, size: RaycastSize, // 1.74, 4.2 for information's sake capsuleDirection: CapsuleDirection2D.Vertical, angle: 0f, direction: Rb2D.velocity, distance: RaycastDistance, // Rb2D.velocity.magnitude * Time.fixedDeltaTime layerMask: Layers.Ground); // 1 << 3 ```

Rb2D.velocity is Vector2.zero in some cases (ie. not a valid direction), and I don't handle this. I've just pushed an update that handles it, 2.1.2. It should arrive in OpenUPM soon.

[Atomiz2002]

It seems it still appears... at the exact same place, and from my experiments it doesnt seem like its just because of the velocity being zero.

[vertxxyz]

I can't seem to replicate this unless I pass NaN into direction or angle from outside. Is there any indication of where/how NaN is being introduced into this codepath for you? If you use the debugger in the CapsuleCast2D:Draw (Shapes.Casts2D.cs:460) method, can you see where NaN gets created when this occurs?

Otherwise I could write some code to protect against it, but it's hard to make it reasonable without knowing what's introducing NaN in the first place.

[vertxxyz]

I've pushed 2.1.3 which should at least silently handle this case.

[Atomiz2002]

Vector2 velocity = Rb2D.velocity * Mathf.Max(0f, 1f - .5f * Time.fixedDeltaTime);

Origin           = Rb2D.position + velocity *
                   Time.fixedDeltaTime + velocity.normalized *
                   (RaycastLength / 2 - RaycastRadius / 2);
Size             = new(RaycastRadius, RaycastLength);
CapsuleDirection = CapsuleDirection2D.Vertical;
Angle            = Mathf.Atan2(velocity.y, velocity.x) * Mathf.Rad2Deg + 90;
Direction        = velocity;
Distance         = RaycastDistance;
LayerMask        = Layers.Ground;

Debug.Log($"{float.IsNaN(Angle)}");

The Debugger:

Shapes.Casts.2D.cs

Shapes.cs

To me it really seems the issue is that dotA sometimes results in a value < -1, which results in NaN (https://learn.microsoft.com/en-us/dotnet/api/system.mathf.acos?view=net-7.0#returns the unity docs dont really note that, but it might be applicable there too, not sure). I checked the value of dotA when the error was not occuring and it was always either -1 or -0.9948...smth. I have no clue why it doesn't seem to appear for dotB in Arc arcA = ... but it might be irrelevant.

Note: this is on v2.1.2

This helps a lot, and makes total sense now thanks! Now I can fix it properly haha. The current release should hopefully be functional, but a future release will fix it properly.
