1.下载Zxing
2.生成二维码图。

//将咱们需要隐藏在码后面的信息赋值上
return m_barcodeWriter.Write(s_formatStr);
}
3.显示在UI上:
Texture2D encoded = encoded = QRCodeHelp.CreateQRCode("星 12123 sd", 256, 256);
panel.m_testImage.texture = new NTexture(encoded);
4.扫描
//二维码识别生成控制类
public class QRCode : MonoBehaviour

//摄像头实时显示的画面
private WebCamTexture m_webCameraTexture;
//申请一个读取二维码的变量
private BarcodeReader m_barcodeRender = new BarcodeReader();
