Figure 8-6.
A spaceship shooting three different sized bullets
In Figure
8-6
, we see a spaceship toward the bottom of the screen. There are a number of circles
above the spaceship; these are bullets that are shot out of the spaceship based on user gestures.
The cluster of three circles toward the upper left are the basic bullets, created from a simple tap. The
circle closest to the bottom is a bigger bullet, created when the user does a long press. If the user
does a touch that is longer than two seconds, an even bigger bullet is fired, as can be seen in the
upper right of Figure
8-6
. Let's take a look at the header file for the class
LongPressController
in
Listing 8-23.
Listing 8-23. LongPressController.h
