Ask about PhysicsShapeCache / Physic / CC_CALLBACK /dettect a collision?

cocos2d-x
#1

Hi, i have problems. Can you help me? :smiley:

  1. How to dettect a collision when my physics body is from physic editor (from code and web)?
error: 'class PhysicsShapeCache' has no member named 'setCollisionBitmask'
shapeCache -> setCollisionBitmask(0x000001);

class PhysicsShapeCache' has no member named 'setContactTestBitmask'
shapeCache -> setContactTestBitmask(true);
  1. I get error when write this code :
void HelloWorld::initPhysics()
{
  auto contactListener = EventListenerPhysicsContact::create();
  contactListener->onContactBegin =  
  CC_CALLBACK_1(HelloWorld::onCollision,this);
  getEventDispatcher() ->addEventListenerWithSceneGraphPriority 
  (contactListener,this);
}

And here is the error:

no matching function for call to 'bind(<unresolved overloaded function type>, HelloWorld*, const std::_Placeholder<1>&)'
#define CC_CALLBACK_1(__selector__,__target__, ...) std::bind(&__selector__,__target__,  std::placeholders::_1, ##__VA_ARGS__)
note: in expansion of macro 'CC_CALLBACK_1'
  	 contactListener->onContactBegin = CC_CALLBACK_1(HelloWorld::onCollision, this);

Some tutorial use that code, right? But i get an error :frowning:
