Unity截屏脚本

发表于 分类于 ，

  1. 作为脚本附到GameObject上，我选择附到相机上

    // 创建这个脚本，挂在任意 GameObject 上
    using UnityEngine;
    using System.IO;

    public class Screenshot : MonoBehaviour
    {
        [Header("截屏设置")]
        public KeyCode screenshotKey = KeyCode.F12;
        public int superSize = 1; // 1 = 原始分辨率, 2 = 2倍分辨率
        
        void Update()
        {
            if (Input.GetKeyDown(screenshotKey))
            {
                TakeScreenshot();
            }
        }
        
        void TakeScreenshot()
        {
            string folderPath = Path.Combine(Application.dataPath, "..", "Screenshots");
            
            // 创建文件夹
            if (!Directory.Exists(folderPath))
            {
                Directory.CreateDirectory(folderPath);
            }
            
            // 生成文件名
            string fileName = $"Screenshot_{System.DateTime.Now:yyyy-MM-dd_HH-mm-ss}.png";
            string filePath = Path.Combine(folderPath, fileName);
            
            // 截图
            ScreenCapture.CaptureScreenshot(filePath, superSize);
            
            Debug.Log($"截图已保存: {filePath}");
        }
    }

  2. 修改编辑器UI，作为菜单使用；需要放到scene文件同目录的Editor目录下

    Editor/ScreenShotTest.csview raw

    using System.IO;
    using System.Threading.Tasks;
    using UnityEditor;
    using UnityEditorInternal;
    using UnityEngine;

    public class ScreenShotTest : MonoBehaviour
    {
        //ctrl + shift + y 截图
        [MenuItem("Screenshot/Take Screenshot %#y")]
        private static async void Screenshot()
        {
            string folderPath = Directory.GetCurrentDirectory() + "\\Screenshots";
            if (!Directory.Exists(folderPath))
            {
                Directory.CreateDirectory(folderPath);
            }

            var timestamp = System.DateTime.Now;
            var stampString = string.Format("_{0}-{1:00}-{2:00}_{3:00}-{4:00}-{5:00}", timestamp.Year, timestamp.Month, timestamp.Day, timestamp.Hour, timestamp.Minute, timestamp.Second);
            ScreenCapture.CaptureScreenshot(Path.Combine(folderPath , stampString + ".png"));

            Debug.Log("截图中......");
            //等待5秒
            await Task.Delay(5000);
            System.Diagnostics.Process.Start("explorer.exe", folderPath);
            Debug.Log("截图" + stampString + ".png");
        }

        void OnMouseDown()
        {
            ScreenCapture.CaptureScreenshot("SomeLevel.png");
        }
    }
    效果如下：
