Calling a derived virtual function

Question

I'm still fairly new to C++ and inheritance has gotten me in a pickle. I know this works in C# since I'm always using Base.();

I'm hoping to be able to call a vector array of PlayerCharacter, derived from Entity. Currently when I call it, it only calls Entity's update method.

int main()
{
vector<Entity*> list;
list.push_back(&PlayerCharacter());

   for(int i = 0; i < list.size(); i++)
   {
   list[0]->Update();
   }
}

class Entity
{
public:
    Entity(void);
   ~Entity(void);
    int hitpoints;
    virtual void Update(void);
};
void Entity::Update(void)
{
    int a = 0;
    a++;
}
class PlayerCharacter : public Entity
{
public:
    PlayerCharacter(void);
    ~PlayerCharacter(void);
    bool Move();
    void Update() override;
};
void PlayerCharacter::Update(void)
{
    int a = 0;
    a--;
}

Answer 1

list.push_back(&PlayerCharacter()); i think this is undefined behavior in your code.

In your case you should allocate the data on the heap like this: list.push_back( new PlayerCharacter() ); otherwise if you do this &PlayerCharacter() then the PlayerCharacter variable will be destroyed immediately and the pointer inside the list will point to garbage bytes.

Also to track which function is called you can use the debugger or print something in the console from each Update function.
