cocos2d-x开启IOS多点触控
参考资料：http://www.cocos2d-x.org/projects/cocos2d-x/wiki/How_to_Enable_Multi-Touch/diff/4
在初始化代码中，开启当前层接受触摸
- this->setTouchEnabled(true);
在AppController.mm文件中，设置开启多点触控
- [__glViewsetMultipleTouchEnabled:YES];
测试一下，重写ccTouchesMoved函数，打印多点触控的位置
- voidHelloWorld::ccTouchesMoved(CCSet*pTouches,CCEvent*pEvent)
- {
- if(pTouches->count()>=2)//多点触控
- {
- CCSetIteratoritor;
- for(itor=pTouches->begin();itor!=pTouches->end();++itor)
- {
- CCTouch*pTouch=dynamic_cast<CCTouch*>(*itor);
- //获得游戏坐标位置
- CCPointccp=pTouch->getLocation();
- printf("%f\t%f\n",ccp.x,ccp.y);
- }
- printf("\n");
- }
- else//单点触控
- {
- CCTouch*pTouch=dynamic_cast<CCTouch*>(pTouches->anyObject());
- CCPointccp=pTouch->getLocation();
- printf("%f\t%f\n",ccp.x,ccp.y);
- }
- }
