## Use

### Use the damuku array

<div className="run-code" data-libs="./uncompiled/artplayer-plugin-danmuku/index.js">▶ Run Code</div>

```js
var art = new Artplayer({
    container: '.artplayer-app',
    url: '/assets/sample/video.mp4',
    autoSize: true,
    setting: true,
    playbackRate: true,
    fullscreenWeb: true,
    plugins: [
        artplayerPluginDanmuku({
            // Damuku array
            danmuku: [
                {
                    text: '111', // Danmu text
                    time: 1, // Video time
                    color: '#fff', // Danmu color
                    border: false, // Danmu border
                    mode: 0, // Danmu mode: 0-scroll or 1-static
                },
                {
                    text: '222',
                    time: 2,
                    color: 'red',
                    border: true,
                    mode: 0,
                },
                {
                    text: '333',
                    time: 3,
                    color: 'green',
                    border: false,
                    mode: 1,
                },
            ],
            speed: 5, // Animation time
            opacity: 1, // Opacity
            color: '#fff', // Font color
            size: 25, // Font size
            margin: ['10%', 20], // Margin top and margin bottom
            synchronousPlayback: false, // Synchronous playback speed
            filter: (danmu) => danmu.text.length <= 50, // filter function
        }),
    ],
});
```

### Use the XML

<div className="run-code" data-libs="./uncompiled/artplayer-plugin-danmuku/index.js">▶ Run Code</div>

```js
var art = new Artplayer({
    container: '.artplayer-app',
    url: '/assets/sample/video.mp4',
    plugins: [
        artplayerPluginDanmuku({
            // Damuku xml，like the Bilibili danmuku format
            danmuku: '/assets/sample/danmuku.xml',
        }),
    ],
});
```

### Use asynchronous calls

<div className="run-code" data-libs="./uncompiled/artplayer-plugin-danmuku/index.js">▶ Run Code</div>

```js
var art = new Artplayer({
    container: '.artplayer-app',
    url: '/assets/sample/video.mp4',
    plugins: [
        artplayerPluginDanmuku({
            // Use promise to return asynchronous
            danmuku: function () {
                return new Promise((resovle) => {
                    return resovle([
                        {
                            text: '111',
                            time: 1,
                        },
                        {
                            text: '222',
                            time: 2,
                        },
                        {
                            text: '333',
                            time: 3,
                        },
