第三阶段：常用功能3-
--Cocos2d-x常用功能-Cocos2d-x用户交互事件处理：触摸、传感器、物理按键（共6部分）
1.Cocos2d-x单点触摸
Size size = Director::getInstance()->getVisibleSize();
auto label = LabelTTF::create( "Click me" , "Courier" , 30 ); label->setPosition(size.width/ 2 ,size.height/ 2 ); addChild(label); auto listener = EventListenerTouchOneByOne::create(); listener->onTouchBegan = [](Touch *t,Event *e){ if (e->getCurrentTarget()->getBoundingBox().containsPoint(t->getLocation())) { log( "onTouchBegan" ); } return true ; }; listener->onTouchMoved = [](Touch* t,Event *e){ log( "onTouchMoved" ); }; listener->onTouchEnded = [](Touch *t,27)">"onTouchEnd" ); };
Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener,label);
2.Cocos2d-x触摸目标判断
//获取当前事件目标也就是label
"onTouchBegan"
);
}
3.Cocos2d-x事件传递
onTouchBegan事件
true
;之后才能执行
onTouchMoved、
onTouchEnded
listener->onTouchMoved = [](Touch* t,27)">"onTouchEnd"
);
};
4.Cocos2d-x多点触摸
安卓的DNK首先配置在环境变量里面
proj.android---
build_native.py
Size visibleSize = Director::getInstance()->getVisibleSize();
auto listener = EventListenerTouchAllAtOnce::create(); listener->onTouchesBegan = [](std::vector<Touch*> ts,27)">"onTouchesBegan" ); }; listener->onTouchesMoved = [](std::vector<Touch*> ts,27)">"touches moved,and touch count is %ld" ,ts.size()); };
Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener,this);
5.Cocos2d-x加速度
acceleration
加速度
加速 stamp
标志/
邮票；印记 double类型 %g
JAVA ADT 里面 右键import 打开proj.android,然后删除依赖项
cocos2d ? cocos ? platform ? android ? java ? src 放在JAVA ADT 的 src 里面 按下F11 选中Android Aplication
//加速度传感器默认处于关闭状态，需要打开
Device::setAccelerometerEnabled(
true
);
Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(EventListenerAcceleration::create([](Acceleration *a,Event *e){ log( "x:%g,y:%g,z:%g" ,a->x,a->y,a->z);
}),162)"> this);
6.Cocos2d-x物理按键交互
auto
listener = EventListenerKeyboard::create();
listener->onKeyReleased = [](EventKeyboard::KeyCode code,27)">"key code : %d" ,code); switch (code) { case EventKeyboard::KeyCode::KEY_BACKSPACE: Director::getInstance()->end(); break ; default : break ; } };
Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener,162)">this);
