如何使用C#拍摄Unity中桌面应用程序当前视图的屏幕截图? [英] How do I take a screenshot of the current view of my desktop app in Unity using C#?

问题描述

我有一个在Unity上制作的桌面应用程序，我想使用主摄像头附带的C#脚本在该应用程序中获取当前视图的屏幕快照.请帮忙.

I have a desktop application that I have made on Unity and I want to take a screenshot of my current view in the application using a C# script attached to the main camera. Please help.

我浏览了在此平台上找到的其他代码段，但似乎无济于事.

I have browsed other code snippets that I found on this platform and nothing seemed to help.

推荐答案

您可以使用CaptureScreenshot .

public class ScreenCapture : MonoBehaviour
{
    //here you can set the folder you want to use, 
    //IMPORTANT - use "@" before the string, because this is a verbatim string
    //IMPORTANT - the folder must exists
    string pathToYourFile = @"C:\Screenshots\";
    //this is the name of the file
    string fileName = "filename";
    //this is the file type
    string fileType = ".png";

    private int CurrentScreenshot { get => PlayerPrefs.GetInt("ScreenShot"); set => PlayerPrefs.SetInt("ScreenShot", value); }

    private void Update()
    {

        if (Input.GetKeyDown(KeyCode.Space))
        {
            UnityEngine.ScreenCapture.CaptureScreenshot(pathToYourFile + fileName + CurrentScreenshot + fileType);
            CurrentScreenshot++;
        }
    }
}

一些注意事项.

1. 我使用了一个逐字字符串来定义您的文件夹
2. 存储屏幕快照的文件夹必须存在(如果要在脚本 Application.dataPath )
3. 之后的注释请求-2 :如果您使用相同的路径和文件名，则文件将被覆盖，因此我添加了一种方法，可以让您保存多个屏幕截图，也可以在不同的会话中使用 PlayerPrefs .

1. I used a verbatim string to define your folder
2. The folder where you store the screenshot must exist (if you want to create it in the script you can follow this answer)
3. AFTER COMMENT REQUEST - 1: If you do not set the folder the file will be saved in the default directory of the application (that changes based on the system - you can check it from Application.dataPath)
4. AFTER COMMENT REQUEST - 2: If you use the same path and filename the file will be overriden, so I added a way to let you save multiple screenshots, also in different sessions using PlayerPrefs.
