General / Game Program (Pong Movement Stutter)

« on: December 06, 2013, 03:06:06 pm »

Hi, I am makeing a pong game, and for my movement, the paddle stutters when it moves, like when you hold down a letter on the keyboard. Taking that in mind I compensated for it in my code. The same strategy worked in another program but not in this one.

main(pong)
pong.cpp:

Code: [Select]

#include <SFML/Graphics.hpp>
#include <SFML/Audio.hpp>
#include "paddle.hpp"

/* Program Flow
init -> mainMenu -> game -> exit / main
*/

int main(){
paddle cayle;
sf::RenderWindow window(sf::VideoMode(800,600), "Pong -By Cayle");
cayle.createSprite();
window.setVerticalSyncEnabled(true);
while(window.isOpen()){
sf::Event event;

while(window.pollEvent(event)){

if(event.type == sf::Event::Closed){window.close();}
cayle.processEvent(event);
}

window.clear(sf::Color::Black);
window.draw(cayle.sprite);
window.display();
}
return 0;
}

paddle class:

Code: [Select]


#include <string>
#include <SFML/Graphics.hpp>
#include "paddle.hpp"

int paddle::getInt(std::string var){
int data;

if(var == "xPos"){
data = this -> xPos;
}else if(var == "yPos"){
data = this -> yPos;
}else if(var == "length"){
data = this -> length;
}
return data;
}

int paddle::move(int distance){
this -> yPos += distance;
return this -> yPos;
}

void paddle::createSprite(){
this -> texture.loadFromFile("../resources/paddleTexture.png");
this -> sprite.setTexture(texture);
}
void paddle::processEvent(sf::Event event){


bool upPress, downPress, leftPress, rightPress;

if(event.type == sf::Event::KeyPressed){

if(event.key.code == sf::Keyboard::Left){
leftPress = true;
}
if(event.key.code == sf::Keyboard::Right){
rightPress = true;
}
if(event.key.code == sf::Keyboard::Up){
upPress = true;
}
if(event.key.code == sf::Keyboard::Down){
downPress = true;
}
}

if(event.type == sf::Event::KeyReleased){

if(event.key.code == sf::Keyboard::Left){
leftPress = false;
}
if(event.key.code == sf::Keyboard::Right){
rightPress = false;
}
if(event.key.code == sf::Keyboard::Up){
upPress = false;
}
if(event.key.code == sf::Keyboard::Down){
downPress = false;
}
}

if(upPress){this -> yPos -= this -> speed;}
if(downPress){this -> yPos += this -> speed;}
sprite.setPosition(this -> xPos, this -> yPos);

}

paddle class header:

Code: [Select]

#ifndef PADDLE_HPP
#define PADDLE_HPP
#include <string>
#include <SFML/Graphics.hpp>
class paddle{
private:


int speed;
int length;


public:
int xPos;
int yPos;
paddle(){
xPos = 60;
yPos = 300;
speed = 7;
length = 80;
}
sf::Texture texture;
sf::Sprite sprite;
void createSprite();
void processEvent(sf::Event);
int move(int distance);
int getInt(std::string var);
};

#endif

Graphics / Screenshot whenever I create a window.

« on: December 01, 2013, 12:43:45 am »

Hey guys, I have my code below. The problem is that when I create the window it just takes a screen shot of whatever is behind it, I tried using the clear command but it doesn't work.

#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>


using namespace std;

int main(){
sf::RenderWindow splashScreen(sf::VideoMode(180, 160), "Naval Command!");


       
while(splashScreen.isOpen()){
        splashScreen.clear();
                sf::Event event;

                while(splashScreen.pollEvent(event)){

                        if(event.type == sf::Event::Closed){
                                splashScreen.close();
                        }
                       
                }
}
return 0;
}

I know this is dumb, but could you give an example?

General / Using SFML in Sublime Text 3

« on: November 17, 2013, 06:42:02 pm »

Hey guys, I am an relatively advanced beginner in c++, and I feel I am ready to start working with graphics. I use sublime text 3 as my editor of choice, and would like to know how to use SFML through it. If someone could give a detailed description on that I would be super happy, thanks.
