The two-dimensional Code of Unity plugin series

1. Common generation and identification of QR codes

1. Forage Two-dimensional code Https://cli.im/text

2. Realization of generating and scanning QR code using zxing in software

Zxing is an open source project written in Java, and Zxing.net is ported to. NET Engineering.

2. realize the identification of two-dimensional code

1.Unity Engineering

2. Let rawimage display the camera content

Using system.collections;using system.collections.generic;using unityengine;using zxing;using UnityEngine.UI;public Class Qrcodetest:monobehaviour {public    rawimage cameratexture;    Private Webcamtexture webcamtexture;//Use this for initializationvoid Start () {        webcamdevice[] devices = Webcamtextu re.devices;        string devicename = Devices[0].name;        Webcamtexture = new Webcamtexture (DeviceName, N.);        Cameratexture.texture = webcamtexture;        Webcamtexture.play ();} Update is called once per framevoid update () {}}

3. Scan function Implementation code (code a bit long, look slowly)

Using system.collections;using system.collections.generic;using unityengine;using zxing;using UnityEngine.UI;public Class Qrcodetest:monobehaviour {public rawimage cameratexture;//storage camera captured content private Webcamtexture webcamtexture;//    The contents of the camera color32[] data;  Barcodereader Barcodereader;//zxing provides a way to read the camera contents float interval = 0f;//do the timer with//use the For Initializationvoid Start ()        {//Open camera webcamdevice[] devices = webcamtexture.devices;        string devicename = Devices[0].name;        Webcamtexture = new Webcamtexture (DeviceName, 400, 300);        Cameratexture.texture = webcamtexture;        Webcamtexture.play (); Barcodereader = new Barcodereader ();}        Update is called once per framevoid update () {interval + = Time.deltatime;            if (interval >= 3f) {scanqrcode ();        Interval = 0f;        }} void Scanqrcode () {//getpixels32 is the way to convert the format to COLOR32 data = Webcamtexture.getpixels32 ();  Result store reads the content      var result = Barcodereader.decode (data, webcamtexture.width, webcamtexture.height); if (result! = null) {Debug.Log (result).        Text); }    }}

3. realize the generation of two-dimensional code (note: I can also successfully identify the generated QR code when I turn off the network, which means it is offline)

1. Create a new rawimage storage generated identification map

2. Added a method to generate a QR code:

Using system.collections;using system.collections.generic;using unityengine;using zxing;using UnityEngine.UI;public Class Qrcodetest:monobehaviour {public rawimage cameratexture;//storage camera captured content public Rawimage qrcode;//store generated QR code p    Rivate webcamtexture webcamtexture;//camera content color32[] data; Barcodereader Barcodereader;//zxing provides methods for reading the contents of the camera Barcodewriter Barcodewriter;//zxing provides methods for writing content float interval = 0f;//        Do the timer with//use the For Initializationvoid Start () {//Open the camera webcamdevice[] devices = webcamtexture.devices;        string devicename = Devices[0].name;        Webcamtexture = new Webcamtexture (DeviceName, 400, 300);        Cameratexture.texture = webcamtexture;        Webcamtexture.play (); Barcodereader = new Barcodereader ();}        Update is called once per framevoid update () {interval + = Time.deltatime;            if (interval >= 3f) {scanqrcode ();        Interval = 0f; }//Press SPACEBAR to generate two-dimensional code if (Input.getkeydown(Keycode.space)) {//In this notation can only fill in the Showqrcode ("I love Learning", 256, 256); What if you want a QR code of another size? See the article at the bottom of the link}}//Scan the QR code method void Scanqrcode () {//getpixels32 is the way to get the color from a picture data = webcamtexture.ge        TPixels32 ();        Result store reads the contents of var result = Barcodereader.decode (data, webcamtexture.width, webcamtexture.height); if (result! = null) {Debug.Log (result).        Text); }}//show generated QR code void Showqrcode (string str,int width,int height) {//define TEXTURE2D and fill texture2d t = n        EW texture2d (width, height);        T.SETPIXELS32 (Geneqrcode (str, width, height));        T.apply ();    Qrcode.texture = t; }//return Color32 Image Color method color32[] Geneqrcode (string formatstr,int width,int height) {ZXing.QrCode.QrCodeEncodin        GOptions options = new ZXing.QrCode.QrCodeEncodingOptions (); Options. CharacterSet = "UTF-8";//Set character encoding, otherwise Chinese cannot display options.        width = width; Options.      Height = width;  Options.  margin = 1;//Two-dimensional code distance Edge Barcodewriter = new Barcodewriter {Format = ZXing.BarcodeFormat.QR_CODE, options = Options        };    Return Barcodewriter.write (FORMATSTR); }}
