unity 生成二维码

Unity可以使用C#编写代码来生成二维码。以下是一个简单的代码示例：

using UnityEngine;
using UnityEngine.UI;
using ZXing;
using ZXing.QrCode;

public class QRCodeGenerator : MonoBehaviour
{
    public RawImage rawImage;
    public InputField inputField;

    void Start()
    {
        GenerateQRCode();
    }

    public void GenerateQRCode()
    {
        Texture2D qrCodeTexture = new Texture2D(256, 256);
        Color32[] pixels = GenerateQRCodePixels(inputField.text, qrCodeTexture.width, qrCodeTexture.height);
        qrCodeTexture.SetPixels32(pixels);
        qrCodeTexture.Apply();

        rawImage.texture = qrCodeTexture;
    }

    private Color32[] GenerateQRCodePixels(string text, int width, int height)
    {
        BarcodeWriter writer = new BarcodeWriter
        {
            Format = BarcodeFormat.QR_CODE,
            Options = new QrCodeEncodingOptions
            {
                Height = height,
                Width = width
            }
        };
        Color32[] pixels = writer.Write(text).ToBitmap().GetPixels();
        return pixels;
    }
}

这个代码将从输入字段中获取文本并将其转换为二维码图像。它使用ZXing库来生成二维码，然后将像素设置为Unity中的纹理。最后，将纹理应用于原始图像。
