cocos2 本地根据文本内容生成二维码

之前做了一个功能，就是cocos2小游戏，结算页面需要有一个二维码，二维码内容是一个网址，这个网址需要根据用户游玩分数确定访问哪个网址，但是这个小游戏是单机小游戏，不连接网络，所以只能通过本地生成二维码展示。

需求

cocos2 本地，将文本内容生成二维码展示在页面。

思路

展示二维码的方式就使用单色节点就可以，直接拖入UI中设置大小位置即可。主要的工作其实是将文本转换成二维码图片，然后把内容赋值给这个单色节点就可以。

实现

创建一个单色节点

创建单色节点很简单，鼠标点几下就出来了，然后稍微设置一下大小和位置就可以啦！

文本转二维码

文本转二维码的话需要一个js文件来支持。

我把这个文件的完整代码贴到这篇博文的最后，就不上传到资源里面去了，免的下载的话还得要C币。

使用JS文件

搞到这个文件之后嘞，很简单，放到项目里面去就可以了，比如下面的图和我一样，当然我是演示了，随便放了，到时候你们根据实际项目结构去放，别放的乱糟糟的。

放进去之后就可以用了，怎么用呢，超级简单，直接拖到刚才创建的单色节点就可以啦！但是需要注意一下哈！就是我们拖拽单色节点的时候，默认会有个Sprite，我们用不到，通过右边的小齿轮删掉他哈！

删掉之后，我们在添加那个JS文件，不然的话会提示我们有一个Sprite了。

删掉自带的，再添加就不会有问题了。

JS 文件一拖上来就发现，原本的单色节点上展示出了二维码！

截图我标注了，其实这个String 就是二维码的文本。修改文本，二维码会随之变化。这样就实现了我们本地将文本内容转化成二维码的功能。

并且微信扫码也可以正常显示内容

好了，完成了！！

CQRCode.js 完整代码

这个代码是我网上找了好久找到的，里面信息我都没有删改过，希望对需要的人有用。
