General / Re: displaying multiple sprites

« on: September 16, 2014, 12:13:40 am »

thanks for the answers and i took a look at the link you sent. I think i'm more familiar with them than I was before.

so here's an update on what I did.

 std::vector<sf::Sprite> object_list;


    sf::Sprite Box;

    Box.setTexture(myTexture);
    object_list.push_back(Box);

        for(int i = 0; i <= object_list.size(); ++i){
        myWindow.draw(object_list[i]);

        }

this does run without any errors but as soon as the application opens up it stays for about 2 seconds then crashes.

General / displaying multiple sprites

« on: September 15, 2014, 01:17:29 am »

so eventually im going to get drawing a lot of sprites at once for example: the environment that the player will be in: the trees, the grass, flowers, etc etc. tilesets in general.

so I thought of going about that through making an std::vector dedicated for holding only sprites and during the main loop there will be a for loop weeding out the sprites and drawing them. But I can't seem to get it to work!

Here's what I've got so far.

defined the vector early on around where i declare the window

std::vector<sf::Sprite> object_list;

then in my main loop its going to call this void im currently working on under a class called Physics which was also declared earlier "myWindow" being the window name.

gamePhysics.draw_objects(&myWindow,&object_list);

and finally the void function itself

void draw_objects(sf::RenderWindow *gameWindow,std::vector<sf::Sprite> *objects){

    for(int i = 0;objects->size();i++){

        &gameWindow->draw(&objects[i]);
    }

};

which keeps throwing this error at me

include\physics.h|19|error: no matching function for call to 'sf::RenderWindow::draw(std::vector<sf::Sprite>*)'|

highlighting this line

&gameWindow->draw(&objects[i]);

and yes im a little knew to C++ programming but on it here and there trying my best lately.
any suggestions would be greatly appreciated!

General / SFML 2.1 error

« on: September 13, 2014, 03:11:50 pm »

Hello, i've been experiencing this frustrating error for hours now, and I can't seem to fix it!

Here's the code (using the sample code from the site)

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
    sf::CircleShape shape(100.f);
    shape.setFillColor(sf::Color::Green);

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear();
        window.draw(shape);
        window.display();
    }

    return 0;
}
 

here's the error.

Network / Problem with sf::UdpSocket

« on: July 17, 2014, 12:52:24 am »

So this error keeps raising up after hours of trying to find whats wrong..

Error   1   error C2248: 'sf::NonCopyable::operator =' : cannot access private member declared in class 'sf::NonCopyable'

I've narrowed down to where the problem occurs through the process of guess and check(keep in mind im using MSV13 if that makes a difference)

server::server(sf::UdpSocket surver, sf::IpAddress ip,
   int por, std::string stats){
   serverIP = ip;
   port = por;
   status = stats;
   serverSLSocket = surver;

specifically here:

serverSLSocket = surver;

Much help is appreciated!
