General / Shape not moving after implementation of collision

« on: September 14, 2015, 08:14:28 pm »

Hi all,
 I have recently started using sfml, and have encountered an issue while implementing collisions in a simple pong game
In the code below, the ball does not move even though it is supposed to, but instead just stays stationary

//Main.cpp

#include <SFML/Graphics.hpp>
#include <iostream>
#include "Player.h"
#include "ball.h"

int main();
sf::RenderWindow window(sf::VideoMode(720, 480), "Pong");
Player player(285, 420);
Ball ball(100, 500);





int main() {
   
   
   player.setPos();
   ball.setPos();

   window.setFramerateLimit(60);
   window.setVerticalSyncEnabled(true);
   
   while (window.isOpen()) {
      sf::Event event;
      while (window.pollEvent(event)) {
         if (event.type == sf::Event::Closed) {
            window.close();
         }
      }
      window.clear(sf::Color::Black);
      window.draw(player.getrPlayer());
      window.draw(ball.getBall());
      player.update();
      ball.ballCollisions(player.getrPlayer());
      ball.update();
      
      window.display();
   }

   return 0;
}

//ball.h

#pragma once
#include <SFML\Graphics.hpp>

class Ball {
public:
   Ball(int x, int y);
   sf::CircleShape getBall();
   void setPos();
   void ballMovement();
   void update();
   int xVel;
   int yVel;
   void ballCollisions(sf::RectangleShape rectangle);
private :
   int x;
   int y;
public:
   int getX();
   int getY();
   int getXVel();
   int getYVel();
   
};

//ball.cpp

#include "ball.h"
#include "Player.h"

sf::CircleShape ball(10);
int xVel = 5;
int yVel = 5;


Ball::Ball(int x, int y) {
   this->x = x;
   this->y = x;
}

int Ball::getX() { return x; }
int Ball::getY() { return y; }

sf::CircleShape Ball::getBall() {
   return ball;
}
void Ball::setPos() {
   ball.setPosition(x, y);
}



void Ball::ballMovement() {

   ball.move(xVel, yVel);

}

void Ball::update() {
   ballMovement();
}

int Ball::getXVel() { return xVel; }
int Ball::getYVel() { return yVel; }

void Ball::ballCollisions(sf::RectangleShape rectangle) {
   if (ball.getGlobalBounds().intersects(rectangle.getGlobalBounds())) {
      xVel *= -1;
      yVel *= -1;
   }
}
