Replace the 0,0 XY location in the iBagel instantiation call to the Bagel() class constructor with WIDTH/2 and
HEIGHT/2 respectively. This uses screen size constants and calculation code inside of a constructor method call,
which will place the iBagel at the center of the screen. Add some different numbers in the Prop object instantiations as
well, to place these tiles at different areas of the screen so we can develop some scoring code next as the InvinciBagel
picks them up. Finally, replace the .setAlignment(Pos.BOTTOM_LEFT); method call with a .setLayoutY(365);
method call to implement fixed positioning of the HBox UI Button elements back where they were before when we
were using StackPane. If you use the Run ➤ Project work process, you will see the result shown on the right half of
Figure 16-43.
