4. We'll handle touch moved only if we are using
_drawing
, which means the
player has pressed on the ship and is now dragging his or her finger across the
screen.
Once the distance between the finger and
_rocket
is greater than the
_
minLineLength
distance we stipulate in game
init
, then we give a visual
cue to the player by adding a glow around
_rocket (_rocket->se-
lect(true))
, and we draw the new line in
_lineContainer
by passing it
the touch's current position and setting the line type to
LINE_TEMP
. If the min-
imum length is not reached, we don't show a line and nor do we show the player
selected.
5. Next comes
onTouchEnded
. There is logic in place already inside our
onTouchEnded
method which deals with game states. You should uncomment
the calls to
resetGame
and add a new
else if
statement inside the method:
} else if (_state == kGamePaused) {
_pauseBtn->setDisplayFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName
("btn_pause_off.png"));
_paused->setVisible(false);
_state = kGamePlay;
_running = true;
return;
}
6. If the game is paused, we change the texture in the
_pauseBtn
sprite through
Sprite->setDisplayFrame
, and we start running the game again.
7. Now we begin handling the touch. First, we determine whether it's landing on the
Pause
button:
if (!_running) return;
if(touch != nullptr) {
