Now that we've put all four of the Actor subclasses that we have created during the
first half of this chapter into service, we can test the application and see what the differ-
ent X and Y axis mirroring does to the prop0.png brick.
Use
Run Project
and test the game to see how each brick is mirrored differ-
ently, as shown in
Figure 14-26
.

Next, let's take a look at how to use large Scene Prop objects to composite back-
ground elements on a Stage.
Using Larger Scene Props: Compositing
with JavaFX
One thing that is really nice about these four Prop Actor subclasses that we have cre-
ated is that they allow us to leverage the PNG8 (background image assets) and PNG32
(true color compositing images with alpha channels) image assets to do digital image
compositing right in our game Scene and Stage objects. If we do not use a fixed prop
with a motion sprite game character by implementing collision detection, and if we
keep these fix props in the background, by watching what we're doing inside of our
