贪吃蛇C++代码
贪吃蛇是一个经典的游戏,其基本原理是玩家控制一个不断移动的蛇,吃掉屏幕上随机出现的食物,每吃掉一个食物,蛇的身体就会变长。游戏的挑战在于蛇不能碰到自己的身体或者墙壁,否则游戏结束。
下面是一个简单的C++代码示例,实现了一个基本的贪吃蛇游戏。请注意,这个示例仅用于教学目的,不包含复杂的图形界面,而是在控制台中运行。
```cpp
#include <iostream>
#include <conio.h>
#include <windows.h>
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");
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; 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); // sleep 100 milliseconds
}
return 0;
}
```
这段代码在控制台中运行,玩家可以使用WASD键控制蛇的移动方向。每次吃到食物,蛇的长度会增加,分数也会增加。如果蛇撞到自己的身体,游戏结束。游戏界面是由字符组成的,蛇用'O'表示,身体用'o'表示,食物用'F'表示。
