SFML projects / Dodge the missile!

« on: September 20, 2014, 12:29:02 am »

Some brief testing with sfml has produced something, well, a quirk.

Should be pretty self-explanatory after you get bombed couple times.
And yes. P for pause.


Short instructions: Drag the waterdrops towards the stickmodel and missiles away.

Feature requests / Websocket feature

« on: April 13, 2014, 02:59:03 pm »

Websockets seems to be pretty cool way to add full-duplex network connection between an app and a web- browser.
It shouldn't be too hard to implement on using RFC 6455 specification.
sf::TcpSocket::Send and ..::Receive functions could take a sf::WebSocketPacket as an argument etc.

I think there are people that might find it useful.

As for now i'm writing my own implementation... which is a little bit dirty codewise so do not wanna share code.

Graphics / Draw Vector of pointers to a class = crash

« on: October 03, 2011, 02:56:45 am »

So i made a function, which makes new tysy object when it's called.
It then pushes the objects to a vector:

Code: [Select]


void piirto::CreateCan()
{
tysy *Can1 = new tysy(Win);
      std::cout << "Object " << Can1 << " says..." << std::endl;
Can1->Hello();
   std::cout << std::endl <<  std::endl;
 Can1++;
    Tyz.push_back(Can1);
}


Now in my mainloop i have:

Code: [Select]


//blabla
    Win.Clear();
    goDraw();
    Win.Draw(p12.s_tysy); //This draws fine.

    Win.Display();


Now the goDraw(); function has :

Code: [Select]


if (i want to do this .. .. . .)
                    for (int i = 0; i < Tyz.size(); ++i)
                            {
                                 Tyz[i]->Hello("buu");
                                 Win.Draw(Tyz[i]->s_tysy); // Crash

                            }


If i call Tyz->Hello("buu"); It prints buu nice and soundy.
But whenever i try to draw those same sprites from s_tysy members using pointers to objects it causes a crash.
Program compiles good.

So if i just make normal tysy object i can draw it's sprite ok.
So why is this pointer thing crashing it?

Code: [Select]

tysy
   .h
        sf::Image       i_tysy;
        sf::Sprite      s_tysy;


   .cpp
i_tysy.LoadFromFile("kanuuna.jpg");
   s_tysy.SetImage(i_tysy);
   s_tysy.SetScale(0.4,0.4);
   s_tysy.SetColor(sf::Color(255,0,0,255));


Any help & instructions are welcome!
