Unity3d中的几种截图方法

Posted 2023-04-18

很抱歉所知甚少，目前我仅知道两种截图方式“
第一种，用自带的API来做，灵活性一般：Application.CaptureScreenshot ("Screenshot.png");
第二种，读屏幕的图像并保存，需要在协程里面等待一帧，示例如下：
IEnumerator OnScreenCapture ()


yield return new WaitForEndOfFrame();//等待这一帧画完了才能截图
try

int width = Screen.width;
int height = Screen.height;
Texture2D tex = new Texture2D ( width, height, TextureFormat.RGB24, false);//新建一张图
tex.ReadPixels (new Rect (0, 0, width, height), 0, 0, true);//从屏幕开始读点
byte[] imagebytes = tex.EncodeToJPG ();//用的是JPG(这种比较小)
tex.Compress (false);
tex.Apply();
Texture2D mScreenShotImgae = tex;
File.WriteAllBytes ( @"E:\\Screenshot.png", imagebytes);

catch (System.Exception e)

Debug.Log ("ScreenCaptrueError:" + e);


如果有路过的大神知道其他的截图方法，请一定要告知我，万分感谢。 参考技术A private IEnumerator GetScreenShot(string mfileName)

yield return new WaitForEndOfFrame();
var texture = ScreenCapture.CaptureScreenshotAsTexture();
byte[] tx = texture.EncodeToPNG();
try

File.WriteAllBytes(mfileName, tx);

catch (Exception ex)

Debug.LogError(ex.Message);

java遍历List中的map的几种方法

 Student 类

public class Student {
	private String name;
	private int age;
	private int taller;
	
	public Student( String name, int age, int taller ) {
		this.name = name;
		this.age = age;
		this.taller = taller;
	}
	
	@Override
	public String toString() {
		StringBuilder builder = new StringBuilder();
		builder.append("Student [name=").append(name).append(", age=").append(age).append(", taller=").append(taller)
				.append("]");
		return builder.toString();
	}

	public String getName() {
		return name;
	}
	
	public void setName(String name) {
		this.name = name;
	}
	
	public int getAge() {
		return age;
	}
	
	public void setAge(int age) {
		this.age = age;
	}
	
	public void setTaller( int taller ) {
		this.taller = taller;
	}
	
	public int getTaller() {
		return taller;
	}
}

 

测试类

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import PubClass.Student;

public class ListAddMap {
	
	public static void main( String args[] ) {
		
		List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
		Map<String, Object> map = new HashMap<String, Object>();
		
		Student stu1 = new Student( "\\u5f20\\u4e09", 26, 180 );
		Student stu2 = new Student( "\\u674e\\u56db", 28, 175 );
		
		map.put( "stu1", stu1 );
		map.put( "stu2", stu2 );
		list.add( map );
		
		System.out.println( "方法一 :" );
        for( int i = 0; i < list.size(); i++ ) {
        	System.out.println( list.get(i) );
        }
        
        System.out.println( "方法二 :" );
        for( Map<String, Object> mapList : list ) {
        	for( String key : mapList.keySet() ) {
        		System.out.println( key + "-->" + mapList.get(key) );
        	}
        }
        
        System.out.println( "方法三 :" );
        for( int i = 0; i < list.size(); i++ ) {
        	Map<String, Object> mapList = list.get(i);
            Iterator<String> it = mapList.keySet().iterator();
            while( it.hasNext() ) {
                String str = (String) it.next();
                System.out.println( "key-->" + str + "\\t value-->" + map.get(str) );
            }
        }
	}
	
}
