Why is virtual function not being called?

Question

//GUITEXT
class guitext : public entity {
public:
    guitext(graphics *gfx, std::string _text, float _x, float _y, 
        float _size, float timeToLive);
    bool upd         


        

Answer 1

You should define entitys to contain pointers to entity. Slightly edited example derived from your code.

#include "stdafx.h"
#include 
#include 

class entity 
{
public:
    virtual void draw() { }
};

class guitext : public entity 
{
public:
    void draw()
    {
        printf("draw");
    }
};

int _tmain(int argc, _TCHAR* argv[])
{
    std::vector entitys;

    guitext g;

    entitys.push_back(&g); 

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

    return 0;
}
