Barrage

Web 端用户界面弹幕组件

弹幕组件的设计分为三种角色: 控制器 | 轨道 | 弹幕
控制器中存放了所有待播放弹幕数据, 当开始播放弹幕的时候, 控制器去寻找合适的轨道投放弹幕

文档

基本用法

  1. 通过 npm 或 yarn 安装,命令 npm install h-barrageyarn add h-barrage

  2. 创建一个容器,这个容器必须要有宽度和高度

<div class="outer-container"></div>
.outer-container {
  width: 100%;
  height: 100%;
}
  1. 引入弹幕样式,准备数据(这里使用组件提供的示例数据),创建 barrage
import { Barrage } from "h-barrage";
import "h-barrage/dist/barrage.css";
import example from "h-barrage/data.json";

const barrage = new Barrage({
  container: document.querySelector(".outer-container"),
  data: example,
});
barrage.play();

export interface BarrageItem {
  // 唯一Key

  // 速度
  speed?: number;
  // 颜色

  // 字体大小
  fontSize?: string;
  // 创建时间

}

BarrageConfig 弹幕全局配置

export class BarrageConfig {
  // 字体大小
  fontSize?: string = '20px';
  // 字体默认颜色
  defaultColor?: string = '#000';
  // 使用随机颜色
  useRandomColor?: boolean = false;
  // 轨道数量
  trackNumber?: number = 3;
  // 轨道高度
  trackHeight?: number = 40;
}
