图像不会出现在我的Java小程序 [英] images do not appear on my java applet

问题描述

嘿，我试图创建一个视频游戏，我测试，看看我是否可以做一个精灵或图像上出现的小程序，我问之前，我的同事和教授的帮助，但他们不似乎帮助。我不知道如果我在错误的位置，或者，如果我的code被窃听有图像，但我会AP preciate如果有人在这谢谢了一下！哦!顺便说一句，我在编写Java和我使用Eclipse JUNO。

解决方案

除非他们签署，小应用程序只能从它们的源是同一个位置加载图像。在这里，你正试图从本地磁盘加载图像。对于小应用程序资源的所有初始化应该从的init 方法来实现。图片可从它们部署在同一个JAR文件被加载为资源。你可以做

 图像exImage = ImageIO.read（的getClass（）。的getResourceAsStream（图像/ myImage.jpg这个参数））
 

Hey I'm trying to create a video game and I'm testing to see if I can make a sprite or image appear on the applet I've asked for help before from my peers and professor, but they don't seem to help. I don't know if I have the image in the wrong location or if my code is bugged, but I would appreciate if someone took a look at it Thanks! Oh! by the way I'm programming in Java and I'm using Eclipse JUNO.

enter code here

package meh;
import java.awt.*;
import javax.swing.JApplet;
import javax.swing.ImageIcon;


public class Draw  extends JApplet{
    public static void main(String[] args)
    {
        Draw test = new Draw();


    }
    private Image exImage;
    private boolean imagesLoaded;

    public void run()
    {

        imagesLoaded = false;

        try
        {
            loadImages();
            try
            {
                Thread.sleep(10000);

            }
            catch(InterruptedException ex){}
        }
        finally{}


    }
    public void loadImages()
    {
        exImage = loadImage("C:/Users/Temp/workspace/From Scratch/bin/Ma_rn_0");
        imagesLoaded = true;
        repaint();
    }
    private Image loadImage(String fileName)
    {
        return new ImageIcon(fileName).getImage();
    }
    public void paint(Graphics g)
    {
        if(g instanceof Graphics2D)
        {
            Graphics2D g2 = (Graphics2D)g;
            g2.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
        }
        if(imagesLoaded)
        {
            drawImage(g, exImage,0,0, null);
        }
        else
        {
            g.drawString("Loading...", 5, 12);
        }
    }

    public void drawImage(Graphics g, Image image, int x, int y, String caption)
    {
        g.drawImage(image, x, y, null);
        g.drawString(caption, x+5, y + 12 +image.getHeight(null));
    }

}

解决方案

Unless they are signed, applets can only load images from the same location from where they originated. Here you are attempting to load an image from the local disk. All initialisation for applet resources should be done from the init method. Images can be loaded as resources from the same JAR file from which they are deployed. You could do

Image exImage = ImageIO.read(getClass().getResourceAsStream("images/MyImage.jpg"))
