java實現(xiàn)動畫的代碼 java實現(xiàn)動畫的代碼有哪些
2.Java有哪幾種常見的實現(xiàn)動畫的方法?
一: 用多線程播放一組圖片, 實現(xiàn)動畫片的效果; 類似于逐幀動畫,每個圖片是動畫的一幀

二: 在awt/swing界面里, 可以使用paint方法,去繪制圖形,然后用swing提供的Timer或者多線程技術,去刷新繪制的圖形
三:在JavaFX里, 本身就支持動畫,并且封裝了很多動畫效果可以直接使用,比如逐幀動畫.縮放動畫,漸變動畫,旋轉動畫,位置動畫等.
強烈推薦使用javaFX來實現(xiàn)動畫, 因為javaFX是現(xiàn)代化的圖形界面工具,具有簡單,強大,組件豐富,跨平臺,支持Html5, 支持表格, 支持動畫等多種優(yōu)勢?

怎么用java做動畫
重寫paint方法，來實現(xiàn)將自己定義的圖片繪制到組件中，然后啟動一個線程來控制paint方法。 示例： ××××××××××××××××××××××××××× import javax.swing.*; import java.awt.*;class MyPanel extends JPanel implements Runnable {private Image img;private int i=0;private int j=0;public MyPanel(){img=new ImageIcon("1.png").getImage();}public void paint(Graphics g){g.drawImage(img,0,0,60,104,i*60,j*104,i*60+60,j*104+104,this);}public void run(){while(true){while(j {while(i {try{Thread.sleep(300);}catch(Exception e){}this.repaint();i++;}j++;i=0;}i=0;j=0;}} }public class test extends JFrame {private MyPanel p;public test(){p=new MyPanel();this.add(p,BorderLayout.CENTER);this.setBounds(300,200,300,300);this.setTitle("人物行走圖");new Thread(p).start();this.setVisible(true);this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);}public static void main(String args[]){new test();} }××××××××××××××××××××××× 將以上源碼保存為：test.java，編譯，然后下載下面的圖片 將下載的圖片改名為1.png" target="_blank"
,然后將其和編譯后生成的class文件放在同一文件夾下，然后運行就可以了·～～
