How to get my circle moving with keys - c++

Question

I am doing one of my first projects on SFML C++ and im trying to combine things now.
What im trying to do is having my Circle which i made with :
sf::CircleShape shape(50);
shape.setPosition(800, 450);
and
shape.setFillColor(sf::Color(100, 250, 50));
now i am trying to move it using W, A, S, D or arrow keys.
But i am not sure how to this, i tried several things like :
if (sf::Keyboard::IsKeyPressed(sf::Keyboard::Up))
Sprite.Move(spriteSpeed * App.GetFrameTime(), 0);
But i am not sure what im doing wrong, can someone help me?
Thanks in advance!
This is the code i have atm.
#include "stdafx.h"
#include<SFML/Graphics.hpp>
#include<string>
#include<iostream>
int main()
{
//Here we declare the render window so we can talk to it.
sf::RenderWindow window;
//sf::VideoMode is to set the size of the window
//The seconds parameter (the string) is for setting the title
//The style is to show/hide the close button and the title bar, or to set full screen
window.create(sf::VideoMode(1600, 900), " My First SFML Game", sf::Style::Titlebar | sf::Style::Close | sf::Style::Resize);
//----------------------------------wait for a key to be pressed-------------------------------------
//This shows a message that you should press a key
/*std::cout << "Press a key to continue." << std::endl;*/
//---------------------------------------------------------------------------------------------------
//----------------------------------Showing a message------------------------------------------------
//Define the messages that will be showed, and the display text
std::string message = "Hello my name is Jean-Paul van Houten";
std::string display = "";
int index = 0;
window.setKeyRepeatEnabled(false);
//----------------------------------------------------------------------------------------------------
sf::CircleShape shape(50);
shape.setPosition(800, 450);
//this while loop will only be called if the window is open.
while(window.isOpen())
{
//Define the event variable
sf::Event eventSF;
//Check if there is an event
while(window.pollEvent(eventSF))
{
shape.setFillColor(sf::Color(100, 250, 50));
//shape.setPosition(eventSF.mouseMove.x 0 sha,eventSF.mouseMove.y);
window.clear();
switch(eventSF.type)
{
case sf::Event::Closed:
window.close();
break;
case sf::Event::MouseEntered:
std::cout << "Mouse within screen bounds" << std::endl;
break;
case sf::Event::MouseLeft:
std::cout << "Mouse outisde the screen bounds" << std::endl;
break;
case sf::Event::MouseMoved:
std::cout << "X: " << eventSF.mouseMove.y << " Y: " << eventSF.mouseMove.y << std::endl;
break;
case sf::Event::MouseButtonPressed:
if(eventSF.mouseButton.button == sf::Mouse::Left)
std::cout << "Left Button Pressed At: X: " << eventSF.mouseButton.x << " Y: " << eventSF.mouseButton.y << std::endl;
break;
case sf::Event::MouseWheelMoved:
std::cout << "Scrolled: " << eventSF.mouseWheel.delta << std::endl;
break;
case sf::Event::GainedFocus:
std::cout << "Window Active" << std::endl;
break;
case sf::Event::LostFocus:
std::cout << "Window Not Active" << std::endl;
break;
case sf::Event::Resized:
std::cout << "Width: " << eventSF.size.width << " Height: " << eventSF.size.height << std::endl;
break;
case sf::Event::TextEntered:
if(eventSF.text.unicode != 8)//(eventSF.text.unicode >= 33 && eventSF.text.unicode <= 126) //This is to only include the characters between the number, now we use punctuation and letters.
std::cout << (char)eventSF.text.unicode;
else if(eventSF.text.unicode == 8)
display = display.substr(0, display.length() - 1);
system("cls");
std::cout << display;
break;
}
window.draw(shape);
//If you release a key
if(eventSF.type == sf::Event::KeyReleased)
{
//and this key is the enter key
if(eventSF.key.code == sf::Keyboard::Return)
{
display += message[index];
index ++;
system("cls"); //CLS on windows, clear on mac/linux
std::cout << display;
}
}
}
window.display();
}
}

First, you have to add the KeyPressed event handling inside the event poll switch, and inside, the code to move your sprite
switch(eventSF.type)
{
[...]
case sf::Event::KeyPressed:
if(eventSF.key.code == sf::Keyboard::Up)
{
shape.move(0, 1)
}
break;
}
Also,
shape.setFillColor(sf::Color(100, 250, 50));
shouldn't be inside the game loop.
And this
window.clear();
window.draw(shape);
window.display();
should be outside the event poll loop:
while(window.isOpen())
{
//Define the event variable
sf::Event eventSF;
//Check if there is an event
while(window.pollEvent(eventSF))
{
[...]
}
window.clear();
window.draw(shape);
window.display();
}
