一:基础思路

可以根据具体需求做这个图标闪烁的功能；下面我介绍一下通过定义点样式和overlay层的方式

二:定义点图标样式的方式

(1) 创建一个矢量图层，然后定义我们的点坐标，设置一个图片样式

创建一个普通图标点的方式如下

                                        
/**
 * 点样式
 */
import { Map, View, Feature } from 'ol';
import { Point } from 'ol/geom';
import { Tile as TileLayer, Vector as VectorLayer } from 'ol/layer';
import { XYZ as XYZSource, Vector as VectorSource } from 'ol/source';
import * as Style from 'ol/style';
import 'ol/ol.css';
let map = new Map({
  target: 'map',
  layers: [
    new TileLayer({
      source: new XYZSource({
        url: 'http://localhost:8084/tiles/{z}/{x}/{y}.png'
      })
    })
  ],
  view: new View({
    center: [102, 34],
    zoom: 3,
    projection: 'EPSG:4326'
  })
});

let source = new VectorSource({
  features: []
});
let layer = new VectorLayer({
  source: source,
  style: function() {
    return new Style.Style({
      image: new Style.Icon({
        src: './static/imgs/warning.png',
        scale: 0.5
      })
    });
  }
});
map.addLayer(layer);

var feature = new Feature({
  geometry: new Point([121, 31])
});
source.addFeature(feature);



                                        
                                    

openlayers的layer和feature都提供了setImage()方法，feature就是其中一个点，所以可以根据需求，要么设置整个图层闪烁，要么设置你想闪烁的个别feature
