我们来用pixi.js 来实现箭头导航线动画
首先数据结构定义 其中多了graph 相关就是拖尾运动sprite的设置
let option = {
renderer: {
type: "simple",
symbol: {
lineColor: "#ffff00",
lineWidth: 4,
arrowSize: 15,
}
},
data: [
{
geometry: [
[12610148.27932812, 2653758.051763372],
[13517124.081943521, 3656135.9369390993]
],
attributes: {
name: "深圳-上海",
}
},
{
geometry: [
[12958063.6570659, 4857420.273468611],
[12716675.521741385, 3593151.825632137]
],
attributes: {
name: "北京-武汉",
}
},
]
};我们通过一些全局变量保存一些信息
// 动画id
this.raf;
// 存放导航线数组
this.graphics = [];
在初始的时候
for (let i in data) {
let item = data[i];
//获取屏幕坐标
let geometry = item.geometry
let XY1 = toScreen(geometry[0]);
let XY2 = toScreen(geometry[1]);
//画箭头图形
let arrow = new PIXI.Graphics();
//获取线条颜色，粗细和箭头尺寸大小
let lineWidth = this.options.renderer.symbol.lineWidth,
lineColor = this.options.renderer.symbol.lineColor,
arrowSize = this.options.renderer.symbol.arrowSize;
