http://array.map/

根据提供的引用，http://array.map/是一个填充程序/ polyfill / replacement，它实现了Array.prototype.map的接口。它可以在ES3支持的环境中使用，并符合ES5规范。

根据引用中的示例代码，Array.prototype.map和Array.prototype.forEach之间有一些区别。Array.prototype.map返回一个由回调函数的返回值组成的新数组，而Array.prototype.forEach则没有返回值。在示例中，arr.map会返回一个由1组成的新数组，而arr.forEach只会遍历数组，没有返回值。

根据引用中的示例代码，示例展示了Java中的Map集合的使用。Map是一种键值对的数据结构，类似于字典。在示例中，map对象存储了不同的键值对，并通过Log打印出来。

同样，这不是一个问题，而是一堆 npm 的警告信息。这些警告信息是告诉你使用的一些库已经被废弃了，建议你更新或者替换掉这些库。比如：

- `stable` 库已经被废弃，因为现代的 JavaScript 已经保证了 `Array#sort()` 是一个稳定的排序。
- `source-map-url` 库已经被废弃，建议使用其他替代库。
- `@hapi/bourne` 和 `@hapi/topo` 库已经被废弃，建议升级到新版本的 `@hapi` 库。
- `eslint-loader` 库已经被废弃，建议使用 `eslint-webpack-plugin`。
- `chokidar` 库已经被废弃，建议升级到新版本的 `chokidar` 库。
- `html-webpack-plugin` 库的 3.x 版本已经不再支持，建议升级到新版本的库。
- `uuid` 库的旧版本可能在某些情况下使用 `Math.random()`，存在问题，建议升级到新版本的库。

还有其他的警告信息也是类似的，建议你根据警告信息逐一解决这些问题。

dataProces() { let data = [ [117.10906365235498, 35.47938508147631], [117.11181476264586, 35.47974199444307], [117.11190387759494, 35.476243578511], [117.10927795137033, 35.47652969177465], [117.10906365235498, 35.47938508147631], ]; 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: new Cesium.ImageMaterialProperty({ transparent: true, //设置透明 image: require("../../assets/images/weilan.png"), repeat: new Cesium.Cartesian2(1.0, 1), }), }, }); }, 根据这段代码 将围栏的图片改成上下滚动的效果

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：

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。
