Scene (on the Stage) to create a game world and enhance the game play experience
(also known as user experience).
We'll create four fixed
Prop
subclasses, using the Actor superclass, which will
make it easy to construct fixed scenes (also called levels, when you have created more
than one). The
Prop.java
class will use your fixed sprite Image assets “as-is,” while
the
PropH.java
class will set the
isFlipH
property to
true
and mirror the image asset
around the Y axis, using a JavaFX
spriteFrame.setScaleX(-1);
Java state-
ment. The
PropV.java
class will set the
isFlipV
property to
true
and mirror the image
asset around the X axis, using a JavaFX
spriteFrame.setScaleY(-1);
Java
statement. The
PropB.java
class (B stands for “both”) will set both the
isFlipV
prop-
erty and
isFlipH
property to
true
, which would mirror an image asset around both the
X and Y axis, using two JavaFX
spriteFrame.setScale(-1);
Java statements.
Once we have created these four Prop-related Actor subclasses, we will use them to
place fixed objects into the Scene to create the first level of this game. That way, when
we get into the collision detection chapter, everything that would be in a real game will
be in place, and we will be able to start coding the collision detection logic; and then,
eventually, an auto-attack engine; and then game play logic, which dictates how the
scoring engine is implemented.
This chapter will be valuable in creating a more feature-filled game. A major part
of any game design, in this case, it is Ira H. Harrison Rubin's InvinciBagel character
and game, is building the environment that the characters (the hero and his or her en-
emies, whether in a single-player or a multi-player game) engage in is critical to the
success and popularity of the game, since these fixed elements are a major part of cre-
ating the game play challenge for the player.
Creating the Prop.java Class: Extending
Actor.java
Open up the InvinciBagel project in NetBeans 8, and
right-click
on the
invincibagel
(package) folder that contains your .java files and select the
New Java Class
menu
sequence. In the
New Java Class
dialog, shown in
Figure 14-1
, name the class
Prop
,
and accept the other default settings, suggested by NetBeans, and then click on the
Fin-
ish
button.
