_player2 =
GameSprite::gameSpriteWithFile("mallet.png");
_player2->setPosition(Vec2(_screenSize.width * 0.5,
_screenSize.height - _player1->radius() * 2));
_players.pushBack(_player2);
this->addChild(_player2);
_ball = GameSprite::gameSpriteWithFile("puck.png");
_ball->setPosition(Vec2(_screenSize.width * 0.5,
_screenSize.height * 0.5 - 2 * _ball->radius()));
this->addChild(_ball);
6. We will create TTF labels with the
Label
class
createWithTTF
static meth-
od, passing as parameters the initial string value (
0
), and the path to the font file.
We will then position and rotate the labels:
_player1ScoreLabel = Label::createWithTTF("0",
"fonts/Arial.ttf", 60);
_player1ScoreLabel->setPosition(Vec2(_screenSize.width
- 60, _screenSize.height * 0.5 - 80));
_player1ScoreLabel->setRotation(90);
this->addChild(_player1ScoreLabel);
_player2ScoreLabel = Label::createWithTTF("0",
"fonts/Arial.ttf", 60);
_player2ScoreLabel->setPosition(Vec2(_screenSize.width
- 60, _screenSize.height * 0.5 + 80));
_player2ScoreLabel->setRotation(90);
this->addChild(_player2ScoreLabel);
7. Then we turn
GameLayer
into a multitouch event listener and tell the
Direct-
or
event dispatcher that
GameLayer
wishes to listen to those events. And we
finish by scheduling the game's main loop as follows:
auto listener = EventListenerTouchAllAtOnce::create();
listener->onTouchesBegan =
CC_CALLBACK_2(GameLayer::onTouchesBegan, this);
listener->onTouchesMoved =
CC_CALLBACK_2(GameLayer::onTouchesMoved, this);
listener->onTouchesEnded =
CC_CALLBACK_2(GameLayer::onTouchesEnded, this);
_eventDispatcher->addEventListenerWithSceneGraphPriority(listener,
