jar文件中的圖像不會顯示

Question

所以我的麻煩是，當我將此游戲放入.JAR文件時，它不會顯示。 我仍然可以看到子彈，但看不到入侵者的圖像

public class Invaders {
protected int xPos;
protected int yPos; 
protected int moveStep = 0;  
protected int size = 15; 


static BufferedImage invader1image = DrawingPanel.loadBitmap("invader1.jpg");
static BufferedImage invader2image = DrawingPanel.loadBitmap("invader2.jpg");

//some code in the middle omitted


public void draw(Graphics g, int seconds) {

    if(seconds%50 < 25){
    g.drawImage(invader1image, 
            this.xPos-this.size, this.yPos-this.size,
            this.size*2, this.size*2,null);
    } else{ g.drawImage(invader2image, // this isn't working
            this.xPos-this.size, this.yPos-this.size,
            this.size*2, this.size*2,null);

    }
}

Answer 1

您應該通過以下方式獲取圖像

BufferedImage invader1image = ImageIO.read(getClass().getResource("invader1.jpg"));

現在，您將圖像放在班級文件中
