【C++】控制台小游戏
移动：W向上，S上下，A向左，D向右
程序代码：
#include <iostream>
#include <conio.h>
#include <windows.h>
using namespace std;bool gameOver;
const int width = 20;
const int height = 17;
int x, y, fruitX, fruitY, score;
int tailX[100], tailY[100];
int nTail;
enum eDirection { STOP = 0, LEFT, RIGHT, UP, DOWN };
eDirection dir;void ClearScreen() {HANDLE hOut;COORD Position;hOut = GetStdHandle(STD_OUTPUT_HANDLE);Position.X = 0;Position.Y = 0;SetConsoleCursorPosition(hOut, Position);
}void Setup() {gameOver = false;dir = STOP;x = width / 2;y = height / 2;fruitX = rand() % width;fruitY = rand() % height;score = 0;
}void Draw() {ClearScreen();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 << "*";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;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(100);}return 0;
}
