c++ - Cocos2d-x PhysicsContact Object Reference -

i'm trying make videogame c++ in cocos2d-x have issue physiccontact.

in gamescene have contact listener check collisions character , objects' physicbody of class item. works fine, want recognize object has collided because want call method of object's class called getthrow().

class item : public cocos2d::layer  {  public:  	sprite* itemart;  	int itemtype;  	physicsbody* itemcollider;    	void createart(int type);  	void getthrow();    	item(int type);  };

i have tried physiccontact information, first obtain object physicbody , node, obtain object's sprite , @ point don't know how reach object call method.

bool level0::oncontactbegin(physicscontact &contact)  {  	auto bodya = contact.getshapea()->getbody()->getnode();  	auto bodyb = contact.getshapeb()->getbody()->getnode();        //here want run bodyb->getthrow()    	return true;  }

i have tried getuserdata() , getuserobject() don't know how call method object pointer.

i don't know if i'm trying incorrectly, appreciate answers.

thanks in advance! (if more details needed tell me, i'm new @ big community)

you need this:

((item*) b->getnode())->getthrow();
