Graphics / Drawing points
« on: September 06, 2019, 07:39:47 pm »
Hello everyone, I am trying to draw around 10,000 points. So instead of calling window.draw(...) 10,000 times I was thinking of putting into a vertex array, and drawing with single draw call.

But how can I increase the point size? I know the OpenGL function that does this, which is glPointSize(...). But is there another way?

Network / HTML setHost
« on: July 17, 2018, 07:36:53 am »
Hello, I was just wondering why i get response error on some webpages and others not. My project is focused on weather, so I want to gather data from the website and read from it. For example, if i set the host to "http://www.google.com/" the program outputs the entire HTML of google.com. But I want it to output the html from the website below...


How do i set the host to that website so it outputs the HTML from the new host?
Here is my code.
#include <SFML/Graphics.hpp>
#include <SFML\Network.hpp>
#include <iostream>

using namespace std;
int main() {
        sf::Http http;
        sf::Http::Request request;
        sf::Http::Response response;
        sf::RenderWindow window(sf::VideoMode(10, 10), "Weather");
        response = http.sendRequest(request);
        cout << "status: " << response.getStatus() << endl;

        if (response.getStatus() == sf::Http::Response::Ok) {
                cout << response.getBody() << endl;
        else {
                cout << "request failed" << endl;
        while (window.isOpen()) {
                sf::Event event;
                while (window.pollEvent(event)) {
                        if (event.type == sf::Event::Closed)


        return 0;

General / Values are still zero after "changing".

Hello, so i am trying to do "sf::Vector2f getSize();" function. I assign the x and y values in the CPP file, but when I call the function outside of the class it's still zero. I tested out by cout ing the values in class CPP file, it outputs the current values. But cout ing outside is zero.

This the class function cpp file.
Note: When i draw a rectangle shape border around the text, it covers the text. So its sizes are correct. So i pass in those sizes to getSize() value.
void Label::setValues() {
        if (firstRun) {

                labelBorder.setPosition(sf::Vector2f(position.x + labelText.getLocalBounds().left, position.y + labelText.getLocalBounds().top));
                labelBorder.setSize(sf::Vector2f(labelText.getLocalBounds().width, labelText.getLocalBounds().height));

                //**** HERE IS THE PROBLEM *****
                labelSize = labelBorder.getSize();
                cout << labelSize.x << "|" << labelSize.y << endl;
                //correct outputs ^ of "74|11"
                firstRun = false;

//for label size its "sf::Vector2f labelSize";

sf::Vector2f Label::getSize() {
        return labelSize;

This is where i call the function outside the file.

void WindowManager::startUp() {
        window.create(sf::VideoMode(windowWidth, windowHeight), "Windows Form");
        label.setLabelName("Hello Button");
        label.setPosition(0, button.getSize().y/2);

        //**** HERE IS THE PROBLEM *****
        button.setPosition(label.getSize().x + 10, button.getPosition().y);
        cout << label.getSize().x << "|" << label.getSize().y << endl;
        //wrong outputs ^ its "0|0"
