Question

求帮忙修改一下java动画

动画中运动的图片会很卡，求帮忙修改，让其运动流畅一点
package luoye;

import java.applet.*;
import java.awt.*;

public class luoye extends Applet{
Image shu,ye1,ye2,ye3,ye4;
int x1 = 320,y1 = 300;
int x2 = 160,y2 = 295;
int x3 = 270,y3 = 320;
int x4 = 105,y4 = 310;

public void playsound(){
AudioClip audioClip=getAudioClip(getCodeBase(),"1324.wav");
audioClip.loop();
}
public void init(){
playsound();
setSize(700,400);
shu = getImage(getCodeBase(), "shu.jpg");
ye1 = getImage(getCodeBase(), "ye1.jpg");
ye2 = getImage(getCodeBase(), "ye2.jpg");
ye3 = getImage(getCodeBase(),"ye3.jpg");
ye4 = getImage(getCodeBase(),"ye4.jpg");
}
public void paint(Graphics g){
g.drawImage(shu, 0, 0, 500, 400, this);
g.drawImage(ye1, x1, y1, 20, 20, this);

public luoye() {

}

int x1 = 320,y1 = 300;

int x3 = 270,y3 = 320;

int x4 = 105,y4 = 310;   

public void playsound(){

AudioClip audioClip=getAudioClip(getCodeBase(),"1.png");

audioClip.loop();

}

public void init(){

//playsound();

setSize(700,400);

shu = getImage(getCodeBase(), "1.png");   

    ye1 = getImage(getCodeBase(), "礼物.png");   

    ye2 = getImage(getCodeBase(), "1.png"); 

    ye3 = getImage(getCodeBase(),"礼物.png");

    ye4 = getImage(getCodeBase(),"1.png");

    }

public void paint(Graphics g){

g.drawImage(shu, 0, 0, 500, 400, this);

g.drawImage(ye1, x1, y1, 20, 20, this);

虽然我没有看懂你的代码

但是有图有真相

效果图

如果你先加快你所谓的树叶的下降速度

try{

Thread.sleep(90);

这里的Thread.sleep(90);可以改成Thread.sleep(45);

Answer 2

你这个应该是渐进的变化，不应该是设置死像素
