我写了一个蛇游戏，当它击中它的尾巴时，它将是Game Over并发出警报。我在新游戏的警报阶段设置了一个按钮，我想先用它来再次运行我的鳕鱼。有什么方法或什么......
这是我的警报课
class alart {
public static void Game_over_alart(int dom) {
dom = (dom - 9) * 10 ;
Label sdom = new Label(Integer.toString(dom));
Stage window = new Stage();
window.setTitle("Game_Over");
Label gameOver = new Label("Game Over");
Label scor = new Label("SCORE : ");
Label best = new Label("BEST : ");
Text newgame = new Text("NEW GAME");
HBox hbox1 = new HBox(2, scor , sdom );
HBox hbox2 = new HBox(2, best);
VBox vbox = new VBox(2, hbox1, hbox2);
gameOver.setStyle(""
+ "-fx-alignment: top;"
+ "-fx-font-size: 40px;"
+ "-fx-font-style: italic;"
+ "-fx-font-weight: bold;"
+ "-fx-font-family: fantasy;"
+ "-fx-text-fill: lightgrey ;");
// + "-fx-background-color: gray");
DropShadow d = new DropShadow(5, Color.BLACK);
ScaleTransition st=new ScaleTransition(Duration.millis(100),newgame);
st.setToX(1.1);
st.setToY(1.1);
st.setFromX(1);
st.setFromY(1);
//st.setAutoReverse(true);
// st.setCycleCount(Animation.INDEFINITE);
gameOver.setEffect(d);
BorderPane b = new BorderPane();
b.setTop(gameOver);
b.setCenter(vbox);
b.setBottom(newgame);
gameOver.setAlignment(Pos.CENTER);
Scene s = new Scene(b, 400, 200);
window.setScene(s);
window.show();
window.setResizable(false);
newgame.addEventHandler(MouseEvent.MOUSE_PRESSED, new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event) {
}
});
newgame.addEventHandler(MouseEvent.MOUSE_ENTERED, new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event1) {
st.play();
}
});
newgame.addEventHandler(MouseEvent.MOUSE_EXITED, new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event1) {
st.setFromX(1.1);
st.setFromY(1.1);
st.setToX(1);
st.setToY(1);
}
});
}
}
这是我的整个代码

答案 0 :(得分：0)
将重启方法移交给警报处理程序。你可以直接或通过界面，例如。 G：
public interface GameManager {
public void restart();
}
您的主类必须实现该接口：
public class Main_Snake extends Application implements GameManager {
public void restart() {
// TODO: reset playfield & restart game
}
public void play() {
...
try {
snake.Move(canvas.getScene());
} catch (Game_Over_Exception e) {
stop();
alart.Game_over_alart(snake.X.size(), Main_Snake.this);
}
...
}
}
在您的alart类中，您调用该方法：
class alart {
public static void Game_over_alart(int dom, GameManager gameManager) {
...
newgame.addEventHandler(MouseEvent.MOUSE_PRESSED, new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event) {
// TODO: close dialog
// restart game
gameManager.restart();
}
});
...
}
}
