Chapter 14 ■ Setting Up the Game Environment: Creating Fixed Sprite Classes Using the Actor Superclass
Next, perform the same work process that you did for the PropV class, and create the PropB class. This class will
set both the isFlipV and isFlipH properties to true, and implement a spriteFrame.setScaleX(-1); method call, as
well as a spriteFrame.setScaleY(-1); method call. Your Java class structure for this last PropB class, which will mirror
fixed prop imagery along both an X and Y axis, can be seen in Figure 14-16 and will look like the following code:
public class PropB extends Actor {
public PropB(String SVGdata, double xLocation, double yLocation, Image... spriteCels) {
super(SVGdata, xLocation, yLocation, spriteCels);
this.setIsFlipH(true);
spriteFrame.setScaleX(-1);
this.setIsFlipV(true);
spriteFrame.setScaleY(-1);
spriteFrame.setTranslateX(xLocation);
spriteFrame.setTranslateY(yLocation);
}
}
As you can see in Figure 14-16, the code is error-free, and you now have a PropB class, which will create fixed
objects for your Scene that are flipped or mirrored around both the X and the Y axis at the same time! Having these
four different fixed Prop classes will allow us to quickly and easily design Scene (and eventually, game levels)
elements, without having to do anything but declare the correct prop class, and reference the correct Image asset and
X,Y locus (location) and collision polygon SVG data.
Figure 14-16. A completed PropB() constructor method creates a fixed PropB object flipped along both the X and Y axis
Now we are ready to use these four new fixed sprite classes, and learn how to add Scene (Stage) elements.
