c++ - SFML only draws some sprites -

i'm having strange problem 1 sprite loading isn't

here main.cpp

    window.draw(universe.getplayer()->draw());  //draw player      std::list<abstractblock*>::const_iterator i;     std::list<abstractblock*>* values = universe.getloadedblocks();      (i = values->begin(); != values->end(); ++i){         window.draw((*i)->draw()); //draw blocks     }      window.display(); 

here can see player drawing , blocks in universe drawing. however, player draws , blocks don't draw @ all. have made sure loop working. because draw() returns void can't see if working or not.

here dirtblock.cpp (i'm inheriting abstractblock)

dirtblock::dirtblock(int x, int y, float rotation, b2world *world){     bodydef.position.set(x, y);     bodydef.lineardamping = .03f;     bodydef.type = b2_dynamicbody;      fixdef.density = .1f;      b2polygonshape shape;     shape.setasbox(16, 16);      fixdef.shape = &shape;      body = world->createbody(&bodydef);     body->createfixture(&fixdef);      texture.loadfromfile("dirt.bmp");      sprite.settexture(texture);     sprite.setorigin(16, 16);   }  sf::sprite dirtblock::draw(){     sprite.setposition(body->getposition().x, body->getposition().y);     return sprite; } 

not included, stuff involved drawing.

my player class similar:

player::player(b2world *world){      texture.loadfromfile("player.bmp");     bodydef.position.set(10, 10);     bodydef.type = b2_dynamicbody;     fixdef.density = .1f;     b2polygonshape shape;     shape.setasbox(16, 16);     fixdef.shape = &shape;      body = world->createbody(&bodydef);     body->createfixture(&fixdef);     body->setlineardamping(.03f);      sprite.settexture(texture);     sprite.setorigin(16, 16);      force = 10.f;  }  sf::sprite player::draw(){     sprite.setposition(body->getposition().x, body->getposition().y);     sprite.setrotation(body->getangle() * (180 / b2_pi));     return sprite; } 

since similar why 1 drawing , other not? have feeling might because of inheritance. i'm typically java programmer , i'm not 100% sure did inheritance correctly in c++. should this? (my dirtblock.h)

class dirtblock: public abstractblock { public:     dirtblock();     dirtblock(int x, int y, float rotation, b2world *world);     ~dirtblock();     virtual sf::sprite draw();     virtual void destroy(b2world *world); private:      sf::sprite sprite; }; 

i fixed myself. turned out stupid mistake on part might write , answer if else makes mistake may find , may fix problem.

i didn't make function draw in abstractblock class virtual. because of this, when calling draw dirtblock, looking draw method in abstractblock didn't have virtual flag.
