多个JPanel的Java swing键绑定

Question

i working on a little game (rpg) in java and i need to move my character with UP, DOWN, LEFT, RIGHT in different panel who represent each level of my game.

I use KeyListener first and this is working fine for the first panel, but not with the other.

I try to make this work with a method who make the movement with panelNumber in argument : (this is working only for the first panel) :

    private void panelSalle2KeyPressed(java.awt.event.KeyEvent evt) {                                       
      int keyCode = evt.getKeyCode();
      deplacementJoueurSalle(keyCode, 2);
    }  

private void characterMove(int keyCode, int panelNumber){
    JLabel panelCharacterSprite= new JLabel();

    switch(panelNumber){
        case 1:
            panelCharacterSprite= characterPanel1;
            break;
        case 2:
            panelCharacterSprite= characterPanel2;
            break;
        case 3:
            panelCharacterSprite= imagePersoSalle3;
            break;
        default:
            imagePerso = null;
            break;
    }
    int x = panelCharacterSprite.getX();
    int y = panelCharacterSprite.getY();

    switch( keyCode ) {
        case KeyEvent.VK_UP:
        if(y-10 >= -3){
            panelCharacterSprite.setLocation(x, y-10);
        }
        break;
        case KeyEvent.VK_DOWN:
        if(y+10 <= 417){
            panelCharacterSprite.setLocation(x, y+10);
        }
        break;
        case KeyEvent.VK_LEFT:
        if(x-10 >= -1){
            panelCharacterSprite.setLocation(x-10, y);
        }
        break;
        case panelCharacterSprite.VK_RIGHT :
        if(x+10 <= 671){
            panelCharacterSprite.setLocation(x+10, y);
        }

I see on stackoverflow that i have to use key binding for make this but i don't really understand how its work.. do it have a chance that i can make work with keylistener ?

Thx

Check out Motion Using the Keyboard .

The KeyboardAnimation.java example shows how you can use Key Bindings on two different components and have both components do animation at the same time while a key is pressed.
