General / Best technique to create infinite sidescroller

« on: November 16, 2023, 10:43:29 pm »

Hi all,
I couldn't find any thread regarding best techniques to create infinite sidescroller.
I thought there would be something like sf::View::set_loop(bool); function that would make it so that if you sf::View::move() outside of the view it would overflow to show start. But there isn't such a feature 

For example think of a game like flappy bird, one would want to simply create 2xWidth render size view and infinitely scroll, add pipes as it goes along and view gets recycled
But just keeping bird steady and moving pipes is ok too I guess.

Network / Simple UDP connection that transfers message using packets

« on: January 02, 2016, 11:36:43 pm »

So, I don't know why this isn't working. I've read some documentation and I've made this code. Both server and client are ran on the same machine.
SERVER

///////SERVER
#include <iostream>
#include <SFML/Network.hpp>
#include <string>

using namespace std;

int main()
{

    sf::UdpSocket socket;
    sf::Packet packet;
    sf::Time time;
    sf::Clock clock;
    int i = 0;
    std::string hello = "Hello World!";
    packet << hello;

// bind the socket to a port
    socket.bind(4000);


    sf::IpAddress recipient = sf::IpAddress::getPublicAddress();
    unsigned short port = 5400;
    while(i == 0)
    {
        time = clock.getElapsedTime();
        if(time.asSeconds() >= 2)
        {
            std::cout << "Sent to: " << recipient << ":" << port << std::endl;
            clock.restart();
            socket.send(packet, recipient, port);
        }
    }

    std::cout << "Adress: " << recipient << std::endl;
    return 0;
}

CLIENT:

/////////////CLIENT
#include <iostream>
#include <SFML/Network.hpp>
#include <string>


int main()
{
    sf::UdpSocket socket;
    sf::Packet packet;
    sf::IpAddress sender;
    unsigned short senderPort, socketPort;
    socketPort = 5400;
    socket.bind(socketPort);
    std::string hello;
    std::cout << sf::IpAddress::getPublicAddress() <<":"<< socketPort << std::endl;

    socket.receive(packet, sender, senderPort);
    packet >> hello;
    std::cout << "received: " << hello << std::endl;

General / Rotating player depending on the mouse position

« on: November 23, 2015, 07:29:01 pm »

So basically I wanna make player1 rotate and always look at the cursor, but I'm stuck. For some reason code below doesn't work

 

click1Pos.x = (int)sf::Mouse::getPosition(cliff->window).x;
        click1Pos.y = (int)sf::Mouse::getPosition(cliff->window).y;
        moveToCursor = true;

        double one = playerYposition - mouseYposition;
        double two = playerX - mouseXposition;
        double tanges = (tan(one/two)* RAD);

        player1.setRotation(tanges);

SFML website / Precompiled binaries Linux 64bit problem

« on: February 26, 2015, 10:13:49 pm »

Basically when you download Linux 64 bit binaries from the SFML website there are 3 files named : "include" "share" and "lib". If you copy that to /usr/local and then compile your program, you should get this error in the terminal:

error while loading shared libraries: libsfml-graphics.so.2

I've renamed "lib" folder which was extracted from the SFML to "lib64" and copied it to /usr/local and now everything works

Feature requests / Auto creating folder if it doesn't exist

« on: December 28, 2014, 02:43:58 pm »

When you are saving something like screenshot using sf::RenderWindow::Capture() and when you are trying to save it to some folder and if that folder doesn't exist, why doesn't it get create it?

General / Is it fine to have sf::Font and sf::Text as global

« on: December 28, 2014, 01:35:53 pm »

So, i have

namespace menu
{
    void loadFiles();
    void menu(sf::RenderWindow &window);
    void main(sf::RenderWindow &window);
    void options();

}

and I have sat up Text and Font inside the menu::loadFiles, and I'm drawing it inside the menu::main(). I've made them global so that I can use it inside both functions and I wanna know is it fine to have them global or should I find some other way?

So I've made a game in which at start is shown Main Menu, and when I click game start user can clearly see that one window is closing and another one opening. How do you guys get rid of that transition. Am I doing something wrong?
