--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();@H_502_8@ @H_502_8@ @H_502_8@ auto label = LabelTTF::create( "Click me" , "Courier" , 30 );@H_502_8@ label->setPosition(size.width/ 2 ,size.height/ 2 );@H_502_8@ addChild(label);@H_502_8@ @H_502_8@ auto listener = EventListenerTouchOneByOne::create();@H_502_8@ listener->onTouchBegan = [](Touch *t,Event *e){@H_502_8@ @H_502_8@ if (e->getCurrentTarget()->getBoundingBox().containsPoint(t->getLocation())) {@H_502_8@ @H_502_8@ log( "onTouchBegan" );@H_502_8@ }@H_502_8@ @H_502_8@ return true ;@H_502_8@ };@H_502_8@ @H_502_8@ listener->onTouchMoved = [](Touch* t,Event *e){@H_502_8@ log( "onTouchMoved" );@H_502_8@ };@H_502_8@ @H_502_8@ listener->onTouchEnded = [](Touch *t,27)">"onTouchEnd" );@H_502_8@ };@H_502_8@

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" );@H_502_8@ }

3.Cocos2d-x事件传递

onTouchBegan事件 true ;之后才能执行 onTouchMoved、 onTouchEnded @H_502_8@

listener->onTouchMoved = [](Touch* t,27)">"onTouchEnd" );@H_502_8@ };

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();@H_502_8@ @H_502_8@ auto listener = EventListenerTouchAllAtOnce::create();@H_502_8@ @H_502_8@ listener->onTouchesBegan = [](std::vector<Touch*> ts,27)">"onTouchesBegan" );@H_502_8@ };@H_502_8@ @H_502_8@ listener->onTouchesMoved = [](std::vector<Touch*> ts,27)">"touches moved,and touch count is %ld" ,ts.size());@H_502_8@ };@H_502_8@ @H_502_8@

Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraPHPriority(listener,this);

@H_502_8@

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 @H_502_8@

cocos2d ▸ cocos ▸ platform ▸ android ▸ java ▸ src 放在JAVA ADT 的 src 里面按下F11 选中Android Aplication

@H_502_8@

//加速度传感器默认处于关闭状态，需要打开

Device::setAccelerometerEnabled( true );@H_502_8@ @H_502_8@ Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraPHPriority(EventListenerAcceleration::create([](Acceleration *a,Event *e){@H_502_8@ @H_502_8@ log( "x:%g,y:%g,z:%g" ,a->x,a->y,a->z);@H_502_8@

}),162)"> this);

@H_502_8@

6.Cocos2d-x物理按键交互

auto listener = EventListenerKeyboard::create();@H_502_8@ listener->onKeyReleased = [](EventKeyboard::KeyCode code,27)">"key code : %d" ,code);@H_502_8@ @H_502_8@ switch (code) {@H_502_8@ case EventKeyboard::KeyCode::KEY_BACKSPACE:@H_502_8@ Director::getInstance()->end();@H_502_8@ break ;@H_502_8@ @H_502_8@ default :@H_502_8@ break ;@H_502_8@ }@H_502_8@ };@H_502_8@

Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraPHPriority(listener,162)">this);
