movement not being drawn
« on: April 05, 2018, 01:24:47 am »
I am currently making a snake game in sfml, however, whenever i try to change the position of the snake, the snake just stops moving, what is a good fix to this problem?


main.cpp
#include <SFML/Graphics.hpp>
#include <iostream>
#include "write.h"
#include <SFML/Graphics/Font.hpp>
#include "menu.h"
#include "snake.h"
#include "wait.h"
int main()
{
sf::RenderWindow windows(sf::VideoMode::getDesktopMode(), "SFML works!",sf::Style::None);
sf::Font fonts;
sf::Clock gameClock;
windows.setKeyRepeatEnabled(false);
if(!fonts.loadFromFile("assets/bit.ttf"))
{

std::cerr << "Error loading font" << std::endl;
}

std::string gameScreen = "Main Menu";
 Snake snake1(10,100,500,0);
snake1.drawSnake(windows);
    while(windows.isOpen())
    {
        sf::Event event;
       
        while (windows.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
            {
                windows.close();
            }
            if(event.type == sf::Event::KeyPressed)
            {
            if(event.key.code == sf::Keyboard::Left)
            {
                if(gameScreen == "Play Game" )
                {

                    snake1.left();
                   
                }
            }
            }
            if(event.key.code == sf::Keyboard::Escape)
            {
             
                 windows.close();
            }
           
        }
     
       
       
       
      if(gameScreen == "Main Menu")
      {
        gameScreen =  buildMenu(fonts,windows);

      }
       
       if(gameScreen == "Play Game")
       {
       
         snake1.moveForward(windows);
         wait(10,gameClock);
       }
    }
     return 0;
   
    }

snake.cpp
#include <SFML/Graphics.hpp>
#include <iostream>
#include <SFML/Graphics/Font.hpp>
#include "snake.h"
#include "wait.h"
#include "math.h"

Snake::Snake( int s, int gx, int gy, int num)          //size,color,x,y)
{
   size = s;
   x = gx;
    y=gy;
  facing = num;
}


void Snake::drawSnake(sf::RenderWindow& window)
{
sf::RectangleShape rectangle2;
rectangle2.setSize(sf::Vector2f(size*10, 20));
rectangle2.setOutlineColor(sf::Color::Transparent);
rectangle2.setOutlineThickness(10);
rectangle2.setPosition(x,y);
rectangle2.setFillColor(sf::Color::White);
window.clear();
window.draw(rectangle2);
window.display();
}
void Snake::moveForward(sf::RenderWindow& window)
{
    Snake::drawSnake(window);
   

  if(cos(facing) == 1)
    {
     x=x+1;

    }
    else if(sin(facing) == 1){
   
    y=y+1;
    }
    else if(cos(facing) == -1)
    {
   
   x=x-1;
   std::cout << "hola";
    }
    else if(sin(facing) == -1)
    {

        y = y-1;
    }

   
}

void Snake::left()
{

    facing = facing + 90;
    std::cout<<facing;
}

void Snake::right()
{
facing = facing -90;
}
