Marker Opacity not changing

[danyhiol]

I found out that the markers opacities never changes.
While debugging your code, I realized that mapPixelBounds.y and mapPixelBounds.x both return undefined, leading to markerDistance to become NaN because of L.bounds() returning object with min and max.
Here is a working code:

// bottom out
            if (y < center.y ){
              y = mapPixelBounds.min.y + markerHeight/2;
              x = center.x -  (center.y-y) / Math.tan(Math.abs(rad));
              markerDistance = -currentMarkerPosition.y - mapPixelBounds.max.y;
            // top out
            }else{
              y = mapPixelBounds.max.y - markerHeight/2;
              x = center.x - (y-center.y)/ Math.tan(Math.abs(rad));
              markerDistance = - mapPixelBounds.max.y + currentMarkerPosition.y ; 
            }
          }else {

            // left out
            if (x < center.x ){
              x = mapPixelBounds.min.x + markerWidth/2;
              y = center.y -  (center.x-x ) *Math.tan(rad);
              markerDistance = -currentMarkerPosition.x;
            // right out
            }else{
              x = mapPixelBounds.max.x - markerWidth/2;
              y = center.y +  (x - center.x) *Math.tan(rad);
              markerDistance = currentMarkerPosition.x - mapPixelBounds.max.x;
            }
          }
