Why doesnt the ball move 10 then wait 1000ms then repeat 10 times

Question

Hi I need help with my Java FX application.
I want the ball to move 10 then wait then move again and repeat.
I have created my button, circle and anchorpane in Scene Builder.
The ball always only move at the end of the for loop
please help.

Here is my code
public class Main extends Application{

public static void main(String [] args){
launch(args);

}

@Override
public void start ( Stage stage ) throws Exception {
Parent loginFOrm = FXMLLoader.load (getClass().getResource ("Resources/Bounce.fxml"));
Scene loginform = new Scene(loginFOrm);
stage.setScene (loginform);
stage.show ();
}

}

public class Bouncecontroller {

@FXML
Button start;
@FXML
Circle ball;

boolean gameRunning;
double ballX, ballY = 0;

public void startGame ( MouseEvent mouseEvent ) throws InterruptedException {
start.setVisible (false);
gameRunning = true;

for (int i = 0; i < 10; i++) {
ballX = ball.getCenterX () + 10;
System.out.println (ballX);
sleep(1000);
ball.setTranslateX (ballX);
}

}
}

Hello Stephen

For animations you can't use a loop.

You will need to use TimeLine or PathTransition.

Here are some tutorials about animations:
