Witam, mam problem z grą Snake w C++ (CodeBlocks), nie chce działać, gdy chcę w nią zagrać pojawia się plansza, lecz zaczyna bardzo szybko "migać", przez co gra jest niemożliwa. Pomoże ktoś? Tu jest kod źródłowy:
#include <iostream>
#include <conio.h>
#include <string>
#include <windows.h>
using namespace std;
bool gameover;
bool shutDown;
const int width = 60;
const int height = 40;
int x, y, fruitX, fruitY, score;
int tailX[400], tailY[400], nTail;
enum eDirection ‹STOP, LEFT, RIGHT, UP, DOWN›;
eDirection dir;
void StartScreen()
‹
system("cls");
cout << "\nWitam w grze SNAKE"
<< "\n\nNacisnij 'e', aby GRAC"
<< "\n\nNacisnij 'q', aby WYJSC"
<< "\n\nNacisnij 'i', aby zobaczyc INSTRUKCJE."
<< "\n\n\nPoprzedni wynik: " << score << endl;
›
void Instructions()
‹
system("cls");
cout << "\nUzyj klawisza 'w' aby ruszac sie w GORE."
<< "\nUzyj klawisza 'a' aby ruszac sie w LEWO."
<< "\nUzyj klawisza 's' aby ruszac sie DOL."
<< "\nUzyj klawisza 'd' aby ruszac sie w PRAWO."
<< "\n\nNacisnij klawisz 'x', aby WYJSC z gry w dowolnym momencie."
<< "\n\nNie dotykaj scian, bo PRZEGRASZ."
<< "\n\nNie jedz wlasnego ogona, bo PRZEGRASZ."
<< "\n\n\nNacisnij 'm', aby wrocic do MENU.\n";
