Unity3D中的文件壓縮

Question

我正在嘗試從我擁有的Unity3D項目中壓縮文件。 我正在使用以下代碼壓縮文件：

private void CompressFolder(string path, ZipOutputStream zipStream, int folderOffset) {

    string[] files = Directory.GetFiles(path);

    foreach (string filename in files) {

        FileInfo fi = new FileInfo(filename);

        string entryName = filename.Substring(folderOffset); // Makes the name in zip based on the folder
        entryName = ZipEntry.CleanName(entryName); // Removes drive from name and fixes slash direction
        ZipEntry newEntry = new ZipEntry(entryName);
        newEntry.DateTime = fi.LastWriteTime; // Note the zip format stores 2 second granularity

        newEntry.Size = fi.Length;

        zipStream.PutNextEntry(newEntry);

        // Zip the file in buffered chunks
        // the "using" will close the stream even if an exception occurs
        byte[ ] buffer = new byte[4096];
        using (FileStream streamReader = File.OpenRead(filename)) {
            StreamUtils.Copy(streamReader, zipStream, buffer);
        }
        zipStream.CloseEntry();
    }
    string[ ] folders = Directory.GetDirectories(path);
    foreach (string folder in folders) {
        CompressFolder(folder, zipStream, folderOffset);
    }
}

該功能實際上將帶有文件夾的目錄作為輸入，並逐個壓縮它們。 我的問題是，進行壓縮時，主要項目處於凍結狀態。 我該如何克服這個問題？

最簡單的方法是使用忍者線程，多線程協程： https ://www.assetstore.unity3d.com/en/#! / content/ 15717

using UnityEngine;
using System.Collections;
using CielaSpike; //include ninja threads

public class MyAsyncCompression : MonoBehaviour {


    public void ZipIt(){
        //ready data for commpressing - you will not be able to use any Unity functions while inside the asynchronous coroutine
        this.StartCoroutineAsync(MyBackgroundCoroutine()); // "this" means MonoBehaviour

    }

    IEnumerator MyBackgroundCoroutine(){
        //Call CompressFolder() here
        yield return null;
    }

    private void CompressFolder(string path, ZipOutputStream zipStream, int folderOffset) {
        /*...
         *... 
          ...*/
    }

}
