RayCast Mask Problem

Unity Engine
1

Here is my code:

         Physics.Raycast (ray,out hit,90,mask);
        //Debug.DrawLine (TimingLight.position,direction,Color.blue,9);
        if (hit.transform != null) {
            //Debug.Log (hit.transform.name);
            var LayerHit = hit.transform.gameObject.layer;
           
            if (LayerHit != 12)
            {
                return LayerHit// <-----Here this is 10?
            }

the mask is set with check marks by 2 layers (layer 11 and 12)

So how is it EVER 10? I tried reversing the mask so everything BUT 11 and 12 are checked but then i get layers like 18, etc… what is going on here?

i just tried this as well: based on examples here (Unity3d Tutorials - How to - Learn Unity: Unity3D Raycast with LayerMask - How layermask works? Working example of Raycasthit and RaycastHit2D and LayerMasks , both in 2D and 3D.):

var Cones = 1 << 12;// cones is layer 12

        var Timing = 1 << 11;//Timing is layer 11 ;

        var Mask2 = Cones | Timing;

        Vector3 direction = TimingLight.TransformDirection(new Vector3(0,-200,0));
        var ray = new Ray(TimingLight.position, direction);
        RaycastHit hit;
        Physics.Raycast (ray,out hit,90,Mask2);
        //Debug.DrawLine (TimingLight.position,direction,Color.blue,9);
        if (hit.transform != null) {
            //Debug.Log (hit.transform.name);
            var LayerHit = hit.transform.gameObject.layer;
            //Debug.DrawLine(TimingLight.position,hit.point,Color.yellow);
            //if ((ConeMask.value & 1 << LayerHit) == 0)
            if (LayerHit != 12) //11=timing
            {
                return BeamTrippedState.Front;
            }

        }

Still hitting layer 10…

I finally figured it out… It was caused buy the fact that my colider was a child of a Rigid body… So change the code to

hit.collider.gameObject instead of hit.transform

go with hit.collider.gameobject
