Add a Java this keyword reference to PropH (object) inside of the constructor and open up method
helper
Double-click on the
.setIsFlipH
method, shown highlighted in
Figure 14-11
,
and
insert a
true
value inside the method call parameter area. The finished
this.setIsFlipH(true);
Java statement can be seen in
Figure 14-12
.

Call the .setIsFlipH() method, off of a Java this (PropH) object reference, and pass it the true setting
value
It is important to note that if we only use the
this.setFlipH(true);
method
invocation in the constructor method, we would still need to observe that
isFlipH
is set
this way, and invoke your
.spriteFrame.setScaleX(-1);
method call, some-
where else in the code. Let's go ahead and put this method call in your constructor
method as well, so that all our PropH objects automatically will have their Image assets
flipped around the Y axis. In case you might be wondering why the .setScaleX(-1)
method mirrors the Image asset around the Y axis, that is something that I was also
wondering about, but what I did was match the isFlipH with the .setScaleX(-1) (since
X is an H or horizontal axis). That said, I would have made .setScaleY(-1) mirror
around the vertical Y axis, which makes more sense to me. Add another line of code
and type
spriteFrame
and hit the
period
key, and select
.setScaleX
in the pop-up, as
seen in
Figure 14-13
.
