Question

设置viewer.scene.scanEffect.show = true;时报错

Answer 1

您好，您是在初始化的时候就直接添加了扫描线的吗？可以这样去写

setTimeout(()=>{
                 viewer.scene.scanEffect.show = true;
                var pos = new Cesium.Cartesian3.fromDegrees(refLayer.lon, refLayer.lat, 10.0);
                viewer.scene.scanEffect.centerPostion = pos;
            },500)
