У меня проблема с объектом Text в моей JavaFX-игре, наклеивающейся на себя, и я не могу на всю жизнь понять, что я делаю неправильно. Объект My Text продолжает вставлять себя, несмотря на то, что я удаляю его, прежде чем добавить новый. Я считаю, что ошибка должна быть в моем методе setTextField, но я включаю код для всего моего класса GamePane ниже, на всякий случай, это полезно. Заранее благодарю за помощь и помощь &! :)JavaFX Text Pastes on Top of Self
Только мой метод setTextField:
public void setTextField() {
Text showScore = new Text("Score: " + String.valueOf(playerPointCounter)
+ "\nMisses: " + String.valueOf(gameOverCounter));
showScore.setLayoutX(25);
showScore.setLayoutY(35);
showScore.setFill(Color.WHITE);
//Font family, weight, font size
showScore.setFont(Font.font("Baskerville Old Face", FontWeight.BOLD, 20));
this.getChildren().remove(showScore);
this.getChildren().add(showScore);
} //End setTextField method
