The corresponding source file is the original code for the implementation of the Snake Game we studied in class. While it does in fact work, it needs a lot of cleanup and improvement (and I do mean a lot). Please take this code and "improve" it to your heart's contentmuch as we studied in class. Use your best coding styles and practices with this particular game.I want to see what you can do with respect to readability, extensibility, maintainability, testability, debugging, modularity, information hiding, valuable commentary, self-documentation. Code provided below
#include#include #include using namespace std; bool gameOver; const int width = 20; const int height = 20; int x, y, fruitX, fruitY, score; int tailX[100], tailY[100]; int nTail; enum eDirecton { STOP = 0, LEFT, RIGHT, UP, DOWN}; eDirecton dir; void Setup() { gameOver = false; dir = STOP; x = width / 2; y = height / 2; fruitX = rand() % width; fruitY = rand() % height; score = 0; } void Draw() { system("cls"); //system("clear"); for (int i = 0; i < width+2; i++) cout << "#"; cout << endl; for (int i = 0; i < height; i++) { for (int j = 0; j < width; j++) { if (j == 0) cout << "#"; if (i == y && j == x) cout << "O"; else if (i == fruitY && j == fruitX) cout << "F"; else { bool print = false; for (int k = 0; k < nTail; k++) { if (tailX[k] == j && tailY[k] == i) { cout << "o"; print = true; } } if (!print) cout << " "; } if (j == width - 1) cout << "#"; } cout << endl; } for (int i = 0; i < width+2; i++) cout << "#"; cout << endl; cout << "Score:" << score << endl; } void Input() { if (_kbhit()) { switch (_getch()) { case 'a': dir = LEFT; break; case 'd': dir = RIGHT; break; case 'w': dir = UP; break; case 's': dir = DOWN; break; case 'x': gameOver = true; break; } } } void Logic() { int prevX = tailX[0]; int prevY = tailY[0]; int prev2X, prev2Y; tailX[0] = x; tailY[0] = y; for (int i = 1; i < nTail; i++) { prev2X = tailX[i]; prev2Y = tailY[i]; tailX[i] = prevX; tailY[i] = prevY; prevX = prev2X; prevY = prev2Y; } switch (dir) { case LEFT: x--; break; case RIGHT: x++; break; case UP: y--; break; case DOWN: y++; break; default: break; } //if (x > width || x < 0 || y > height || y < 0) // gameOver = true; if (x >= width) x = 0; else if (x < 0) x = width - 1; if (y >= height) y = 0; else if (y < 0) y = height - 1; for (int i = 0; i < nTail; i++) if (tailX[i] == x && tailY[i] == y) gameOver = true; if (x == fruitX && y == fruitY) { score += 10; fruitX = rand() % width; fruitY = rand() % height; nTail++; } } int main() { Setup(); while (!gameOver) { Draw(); Input(); Logic(); Sleep(10); //sleep(10); } return 0; }
