Hello, I am still learning SFML and have created a basic program where you can move a character around the screen with an animation. You can also sprint which also speeds up the animation!
I wanted to ask if I have done everything correctly and you can correct me if not.
main.cpp#include <SFML/Graphics.hpp>
#include <iostream>
#include "player.h"
int main()
{
//Window
sf::RenderWindow window(sf::VideoMode(1200, 700), "Testing");
window.setKeyRepeatEnabled(false);
//Load Player Texture
sf::Texture playerTexture;
if(!playerTexture.loadFromFile("IMAGE/playerSprite.png"))
std::cout << "Texture Error" << std::endl;
//OBJECTS
Player player(playerTexture); //Player
//Game Loop
while (window.isOpen())
{
sf::Event event;
while (window.pollEvent(event))
{
if (event.type == sf::Event::Closed)
window.close();
}
window.clear(); //Clear Window
//PLAYER MOVEMENT
if (sf::Keyboard::isKeyPressed(sf::Keyboard::W)) //Move Up
player.moveUp();
else if(sf::Keyboard::isKeyPressed(sf::Keyboard::S)) //Move Down
player.moveDown();
else if(sf::Keyboard::isKeyPressed(sf::Keyboard::D)) //Move Right
player.moveRight();
else if(sf::Keyboard::isKeyPressed(sf::Keyboard::A)) //Move Left
player.moveLeft();
//SPRINT
if(sf::Keyboard::isKeyPressed(sf::Keyboard::LShift))
player.setSpeed(0.35, sf::milliseconds(50));
else
player.setSpeed(0.20, sf::milliseconds(80));
window.draw(player.getSprite()); //Draw Player Sprite
window.display(); //Display Window
}
return 0;
}

I was guessing it wasn't but I'm glad I asked haha, I'll get there eventually. I have an idea in my head now of how it works.
