Question

Hello all so I m Creat a brief 2Dmmer, and so standard, I ve had a bit of a hamaretries to access each other. 到目前为止,我拥有一个主要的菜单、游戏网和显示网上的形象。我现在要处理这一运动,但我似乎不能让它发挥作用。

问题可能在于您对 object客如何工作的理解,该物体可能是由WareHouseKeeper和AlexLoader等编造的,但该物体是在级别上播放的,也就是说,如果你将目标放在必须移到级别上的话。比如,你是

    private static void moveWareHouse(Scene scene, final WarehouseKeeper keeper) {

scene.setOnKeyPressed(new EventHandler<KeyEvent>() {

    @Override
    public void handle(KeyEvent event) {

        switch (event.getCode()) {

        case W:
            keeper.setyPosition(keeper.getyPosition() - KEYBOARD_MOVEMENT_DELTA);
            break;
        case D:
            keeper.setxPosition(keeper.getxPosition() + KEYBOARD_MOVEMENT_DELTA);
            break;
        case A:
            keeper.setyPosition(keeper.getyPosition() + KEYBOARD_MOVEMENT_DELTA);
            break;
        case S:
            keeper.setxPosition(keeper.getxPosition() - KEYBOARD_MOVEMENT_DELTA);
            break;
        }
    }
});
}

As the object has been passed to the function you would only need to move it directly from within the level class and not from the other Classes, so this would be changed to

    private static void moveWareHouse(Stage theStage, Group wHK) {

        theStage.addEventFilter(KeyEvent.KEY_RELEASED, e -> {
        e.consume();

        switch (e.getCharacter()) {

        case W:
            keeper.setLayoutY(keeper.getLayoutY() - KEYBOARD_MOVEMENT_DELTA);
            break;
        case D:
            keeper.setLayoutX(keeper.getLayoutX() + KEYBOARD_MOVEMENT_DELTA);
            break;
        case A:
            keeper.setLayoutY(keeper.getLayoutY() + KEYBOARD_MOVEMENT_DELTA);
            break;
        case S:
            keeper.setLayoutX(keeper.getLayoutX() - KEYBOARD_MOVEMENT_DELTA);
            break;
        }
    });
}

EDIT I also noticed you have the Scene parsed as the key listener this would require you to click on the scene (to give it focus) before it will listen to the keys, if you set the stage as the key listener no matter where you click it will always be the root focus and always listening for keys.

EDITED FURTHER As I mentioned in our conversation up the top, your better off creating the entirety of the WarehouseKeeper in your WarehouseKeeper class and instantizing it into your main class (level1) this way the control of the object is within the level1 but level1 does not have all the code to create it (so if you need to modify the creation of it later or use it again you can call more of them by just creating a new instance of it and adding it to the scene) for example.

public final Group warehouseKeeper(ImageView image) {
    Group tempGroup;
    /* insert necessary code here to add image to group and anything else you want in the group */
    return tempGroup;
}

然后,你可以简单地呼吁,将它提高到1级。

final Group wHK = new WarehouseKeeper.warehouseKeeper();
wHK.setLayoutX(/*some init val */);
wHK.setLayoutY(/*some init val */);
root.getChildren().add(wHK);
