Java摆动图像路径

Question

The class is extracted from a game project. Everything works as it should, I can play the game, start a new game, etc. Only the .gif pics are not displayed. Where in my project do I have to store the .gif pics, so that the image path works? I hope the code is understandable.

class Field extends JPanel {
//fields in x direction
static final int max_x = 10;
//fields in y direction
static final int max_y = 10;
//array for field
JLabel[][] label = new JLabel [max_x][max_y];
//home-directory
String img_source = MainWindow.getDirectory();
//separator
String separator = MainWindow.getSeparator();
//stringarray for different viewing direction
String [] viewing_direction = {"player.gif", "player1.gif", "player2.gif", "player3.gif", "player4.gif", null, "player6.gif", "player7.gif", "player8.gif", "player9.gif", "loss.gif", "win.gif"};
//integer for last viewing direction
int viewing_direction_Player = 0;


Field() {
    super();
    this.setLayout(new GridLayout(max_x, max_y));
    //set theme "game"
    img_source = img_source + "image" + separator + "Game";
    addJLabels();
}

//creates field with alternating background
private void addJLabels() {
    for (int i = 0; i < max_y; i++) {
        for (int k = 0; k < max_x; k++) {
            label[i][k] = new JLabel();
            if((i+k) % 2 == 0) {    //modulo operation for alternating background
                label[i][k].setBackground(Color.BLACK);
            }
            else {
                label[i][k].setBackground(Color.WHITE);
            }
            label[i][k].setPreferredSize(new Dimension(50, 50));
            label[i][k].setOpaque(true);
            this.add(label[i][k]);
        }
    }
}



//method to get last viewing direction
public void setLastDirection(int lastDirection) {
    viewing_direction_Player = lastDirection;
}


//method that draws all pawns
public void drawAllPawns(AbstractPawn[] pawns) {
    for(int i = 0; i < (int) pawns.length; i++) {
        if ((pawns[i].getX() < 0) || (pawns[i].getY() < 0)) {

        } else if (pawns[i] instanceof Player) {
            label[pawns[i].getY()][pawns[i].getX()].setIcon(new ImageIcon(img_source + separator + viewing_direction[viewing_direction_Player]));
        } else if(pawns[i] instanceof Opponent) {
            label[pawns[i].getY()][pawns[i].getX()].setIcon(new ImageIcon(img_source + separator + "opponent.gif"));
        } else if(pawns[i] instanceof Vortex) {
            label[pawns[i].getY()][pawns[i].getX()].setIcon(new ImageIcon(img_source + separator + "vortex.gif"));
        } else if(pawns[i] instanceof Obstacle) {
            label[pawns[i].getY()][pawns[i].getX()].setIcon(new ImageIcon(img_source + separator + "obstacle.gif"));
        } else if(pawns[i] instanceof Destruction) {
            label[pawns[i].getY()][pawns[i].getX()].setIcon(new ImageIcon(img_source + separator + "destruction.gif"));
        } else if(pawns[i] instanceof Ammo) {
            label[pawns[i].getY()][pawns[i].getX()].setIcon(new ImageIcon(img_source + separator + "ammo.gif"));
        }
    }
}

Here is the getDirectory from my mainwindow class

public static String getDirectory() {
    String home = System.getProperty("user.dir");
    return (home + getSeparator());
}

Simple way to use image

First drag and drop image in src folder

than type this code

ImageIcon ic = new ImageIcon(getResource().getClass("Example.jpg")); // image name instead of Example.jpg
