您可以将`ImageMaterialProperty`的`image`属性设置为一个动态的图片序列,来实现上下滚动的效果。以下是一些示例代码,可以将其添加到您的`dataProces`函数中:
```javascript
let imageUrls = [
require("../../assets/images/weilan1.png"),
require("../../assets/images/weilan2.png"),
require("../../assets/images/weilan3.png"),
require("../../assets/images/weilan4.png"),
require("../../assets/images/weilan5.png"),
];
let currentIndex = 0;
let intervalId = setInterval(() => {
currentIndex = (currentIndex + 1) % imageUrls.length;
imageMaterial.image = imageUrls[currentIndex];
}, 200);
let imageMaterial = new Cesium.ImageMaterialProperty({
transparent: true,
image: imageUrls[currentIndex],
repeat: new Cesium.Cartesian2(1.0, 1),
});
let coor = Array.prototype.concat.apply([], data);
let datasouce = this.map_common_addDatasouce("wall");
datasouce.entities.add({
wall: {
positions: Cesium.Cartesian3.fromDegreesArray(coor),
maximumHeights: new Array(data.length).fill(300),
minimunHeights: new Array(data.length).fill(0),
material: imageMaterial,
},
});
// 在组件销毁前清除定时器
beforeDestroy() {
clearInterval(intervalId);
}
```
在上面的代码中,我们首先定义了一个`imageUrls`数组,其中包含了一组动态图片序列。然后,我们使用`setInterval`函数在每200毫秒更改一次`ImageMaterialProperty`的`image`属性,使图片序列上下滚动。最后,我们将`imageMaterial`对象作为`wall`实体的材质属性,并将其添加到场景中。
需要注意的是,由于使用了定时器来实现动态效果,因此在组件销毁前需要清除定时器,以避免内存泄漏。在Vue.js中,您可以在`beforeDestroy`生命周期钩子中清除定时器。
