gamemycanvas01.java

J2ME的源码！我以前学习J2ME的源码哈！非常适合初学者

package TestDemo01;

import javax.microedition.lcdui.Image;
import javax.microedition.lcdui.game.GameCanvas;
import javax.microedition.lcdui.game.Sprite;

	private Image image;
	private Sprite sprite;
	

	protected gameMyCanvas01() {
		super(true);
		try{
			image=Image.createImage("/fly1.PNG");
			
		}
		catch(Exception e){
			e.printStackTrace();
			
		}
		g=this.getGraphics();
		g.setColor(255,255,255);
		sprite =new Sprite(image,155,138);
		sprite.setPosition(20, 50);
		sprite.defineReferencePixel(sprite.getWidth()/2, sprite.getHeight()/2);
		sprite.paint(g);
		this.flushGraphics();
		
		
		
	}
	public void transform(int angle){
