# ZGDanmaku

This is an android library which use opengles 2.0 to renderer danmaku effect.

## 初衷/Introduction

在Github上能找到很多开源的弹幕库，并且有很多是优秀的实现，基本上能够满足大众的需求，但是我却找不到使用opengles实现渲染的。于是我就自己着手学习一下opengles，并简单实现了一个弹幕。

## 效果/Demo

## 实现原理/Understanding Android OpenGLES

- [Android OpenGLES学习之入门理解](http://zhgeaits.me/android/2014/10/16/android-opengles-study-notes.html)

- [Android OpenGLES学习之实现弹幕渲染](http://zhgeaits.me/android/2016/02/27/android-opengles-danmaku-study-notes.html)

## 使用/Usage

- 在xml布局中使用

```

```

- 然后在java代码中使用

```

IZGDanmakuView danmakuView = (IZGDanmakuView) findViewById(R.id.danmaku);

danmakuView.setSpeed(100);//设置弹幕速度，单位px/s

danmakuView.setLines(24);//设置弹幕行数

danmakuView.setLeading(2);//设置行距

danmakuView.start();

```

- 发送弹幕和控制

```

for (int i = 0; i < 1000; i ++) {

    danmakuView.shotTextDanmamku("hello world!");

}

Button closeSwitcher = (Button) findViewById(R.id.openOrClose);

closeSwitcher.setOnClickListener(new View.OnClickListener() {

    @Override

    public void onClick(View v) {

        if(danmakuView.isHide()) {

            danmakuView.show();

        } else {

            danmakuView.hide();

        }

    }

});

Button pauseSwitcher = (Button) findViewById(R.id.pauseOrResume);

pauseSwitcher.setOnClickListener(new View.OnClickListener() {

    @Override

    public void onClick(View v) {

        if(danmakuView.isPause()) {

            danmakuView.resume();

        } else {

            danmakuView.pause();

        }

    }

});

```

## TODO

1.修改弹幕逻辑

2.修改为时间同步策略

### Dependencies

1.由于glsurfaceview不能介于view的中间层，要么底层，要么顶层，是做不到处于中间层，然后透明的，所以需要使用TextureView。

GLTextureView：  

- [eaglesakura's GLTextureView](https://github.com/eaglesakura/gltextureview.git)

- [Google's GLTextureView](https://github.com/romannurik/muzei/blob/master/main/src/main/java/com/google/android/apps/muzei/render/GLTextureView.java)

2.使用了[DanmakuFlameMaster的创建bitmap方法](https://github.com/Bilibili/DanmakuFlameMaster)
