my two sprites are roll and hero. i want to detect their collision using box2d in cocos2d-x i have got both the sprites moving on the screen (roll automatically, hero manually).
all i want to do is call the function intersection();
when the two sprites collide. (sprites are declared globally in the *.h file)
