Hi,

I am trying to create a dashed polyline and I run into a weird issue.

The material:

var myMaterial = new Cesium.PolylineDashMaterialProperty({

color: Cesium.Color.WHITESMOKE,

gapColor: Cesium.Color.TRANSPARENT

});

The poly line:

var myPolyline = Cesium.entities.add({

id: name + ‘\_polyline’,

height: 0,

polyline: {

positions: [new Cesium.Cartesian3(uPosition.x, uPosition.y, uPosition.z),

new Cesium.Cartesian3(newCenter.x, newCenter.y), newCenter.z)],

width: 3,

material : myMaterial

}

});

The issue is that when I put a break point at the material, I get there, but it is hanging there and not reaching the myPolyline creation when I continue.

Any idea?

Hi there,

Looks like you have an extra parenthesis:

new Cesium.Cartesian3(newCenter.x, newCenter.y), newCenter.z)

``

Make sure your code is syntactically correct, then see if you’re still having any problems.

Thanks,

Gabby
