Unity's IPreprocessBuildWithReport: In-depth analysis and practical cases

Unity IPreprocessBuildWithReport

Unity IPreprocessBuildWithReport is a very useful function in the Unity engine, which allows developers to automatically perform some operations when building a project, and can obtain a build report. This function can help developers improve work efficiency and reduce manual operation time and error rate. In this article, we will introduce how to use Unity IPreprocessBuildWithReport, and provide three usage examples to help readers better understand this.

How to use Unity IPreprocessBuildWithReport

Unity IPreprocessBuildWithReport is an interface that contains a method named processBuild. In this method, we can write the actions we need to perform, and we can get the build report. The following is a simple example that demonstrates how to automatically open a directory when building a project and get a build report:

using UnityEditor;
using UnityEngineusing UnityEditor.Build;
using UnityEditor.Build.Reporting;
using System.Diagnostics;

public class BuildHandler : IPreprocessBuildWithReport
{
    public int callbackOrder { get { return 0; } }

    public void OnPreprocessBuild(BuildReport report)
    {
        string outputPath = report.summary.outputPath;
        Process.Start(outputPath);
        Debug.Log(report.summary.result.ToString());
    }
}

In this example, we implement the IPreprocessBuildWithReport interface and override its PreprocessBuild method. In this method, first obtain the output path of the build report, and then use the Process.Start method to open the output directory. Finally, we use the Debug.Log method to output the results of the build report.

Example of use

Below are three examples of using Unity's IPreprocessBuildWithReport, each of which provides a concrete implementation.

Example 1: Automatically upload build results

In this example, we will demonstrate how to automatically upload build results when building a project, and get a build report.

using UnityEditor;
using UnityEngine;
using UnityEditor.Build;
using UnityEditor.Build.Reporting;
using System.Net;
using System.IO;

public class BuildHandler : IPreprocessBuildWithReport
{
    public int callbackOrder { get { return 0; } }

    public void OnPreprocessBuild(BuildReport report)
    {
        string outputPath = report.summary.outputPath;
        string url = "http://myserver.com/upload.php";
        WebClient client = new WebClient();
        client.UploadFile(url, outputPath);
        Debug.Log(report.summary.result.ToString());
    }
}

In this example, we implement the IPreprocessBuildWithReport interface and override its PreprocessBuild method. In this method, we first obtain the output path of the build report, then specify the upload URL, create a WebClient object, and call its UploadFile method to upload the build result to the specified URL. Finally, we use the Debug.Log method to output the results of the build report.

Child 2: Automatically send emails

In this example, we will demonstrate how to automatically send emails when a project is built, and get build reports.

using UnityEditor;
using UnityEngine;
using UnityEditor.Build;
using UnityEditor.Build.Reporting;
using System.Net;
using System.Net.Mail;

public class BuildHandler : IPreprocessBuildWithReport
{
    public int callbackOrder { get { return 0; } }

    public void OnPreprocessBuild(BuildReport report)
    {
        string outputPath = report.summary.outputPath;
        string subject = "Build completed successfully!";
        string body = "The build has been completed successfully.";
        string from = "[email protected]";
        string to = "[email protected]";
        string password = "mypassword";
        SmtpClient client = new SmtpClient("smtp.gmail.com", 587);
        client.EnableSsl = true;
        client.Credentials = new NetworkCredential(from, password);
        MailMessage message = new MailMessage(from, to, subject, body);
        Attachment attachment = new Attachment(outputPath);
        message.Attachments.Add(attachment);
        client.Send(message);
        Debug.Log(report.summary.result.ToString());
    }
}

In this example, we implement the IPreprocessBuildWithReport interface and override its PreprocessBuild method. In this method, we first get the output path of the build report, and then specify the subject and body of the email. Next, we specify the sender's and recipient's email addresses, as well as the sender's password. Then, we create a SmtpClient object and set its SMTP server and port number. Next, we create a MailMessage object and set its sender, recipient, subject, and body. Finally, we create an Attachment object and attach the result of the build to the email. Then, we call the Send method of SmtpClient to send the mail. Finally, we use the Debug.Log method to output the results of the build report.

Example 3: Automatic upload to FTP server

In this sub, we will demonstrate how to automatically upload to an FTP server when building a project, and get a build report.

using UnityEditor;
using UnityEngine;
using UnityEditor.Build;
using UnityEditor.Build.Reporting;
using System.Net;

public class BuildHandler : IPreprocessBuildWithReport
{
    public int callbackOrder { get { return 0; } }

    public void OnPreprocessBuild(BuildReport report)
    {
        string outputPath = report.summary.outputPath;
        string ftpUrl = "ftp://myserver.com/";
        string ftpUser = "myusername";
        string ftpPassword = "mypassword";
        WebClient client = new WebClient();
        client.Credentials = new NetworkCredential(ftpUser, ftpPassword);
        client.UploadFile(ftpUrl + "build.zip", outputPath);
        Debug.Log(report.summary.result.ToString());
    }
}

In this example, we implement the IPreprocessBuildReport interface and override its PreprocessBuild method. In this method, we first get the output path of the build report, and then specify the username and password of the FTP server. Next, we create a WebClient object and set its Credentials property to the specified username and password. Then, we call the UploadFile method of WebClient to upload the result to the FTP server. Finally, we use the Debug.Log method to output the results of the build report.

in conclusion

Unity IPreprocessBuildWithReport is a very useful function that can help developers improve operation efficiency and reduce manual operations and error rates. In this article, we introduce how to use Unity IPreprocessBuildReport, and provide three examples to help readers better understand this function. Hope this article is helpful to readers.
