unity pc截图保存

您好，关于Unity PC截图保存的问题，可以使用以下代码实现：

using UnityEngine;
using System.IO;

public class ScreenShot : MonoBehaviour
{
    public int captureWidth = 1920;
    public int captureHeight = 1080;
    private string captureDirectory = @"C:\Screenshots\";

    void Update ()
    {
        if (Input.GetKeyDown(KeyCode.S))
        {
            TakeShot();
        }
    }

    void TakeShot()
    {
        // Create directory if it does not exist
        if (!Directory.Exists(captureDirectory))
            Directory.CreateDirectory(captureDirectory);

        // Define image name with timestamp
        string timeStamp = System.DateTime.Now.ToString("yyyyMMdd-HHmmss");
        string fileName = "screenshot_" + timeStamp + ".png";
        string path = captureDirectory + fileName;

        // Capture screenshot
        Texture2D screenShot = new Texture2D(captureWidth, captureHeight, TextureFormat.RGB24, false);
        RenderTexture rt = new RenderTexture(captureWidth, captureHeight, 24);
        Camera camera = Camera.main;
        camera.targetTexture = rt;
        RenderTexture.active = rt;
        camera.Render();
        screenShot.ReadPixels(new Rect(0, 0, captureWidth, captureHeight), 0, 0);
        camera.targetTexture = null;
        RenderTexture.active = null;
        Destroy(rt);

        // Encode image and save to file
        byte[] bytes = screenShot.EncodeToPNG();
        using (FileStream file = File.OpenWrite(path))
        {
            file.Write(bytes, 0, bytes.Length);
        }

        Debug.Log("Screenshot captured: " + path);
    }
}

该代码将在按下"S"键时，截取主摄像机当前的画面，并将其保存在"C:\Screenshots\"目录下，以"yyyyMMdd-HHmmss"格式的时间戳命名。如有需要，可以根据实际情况更改保存路径和文件名。希望能对您有所帮助。
