Ⅲ c語言 貪吃蛇 程序

蛇每吃一個食物蛇身子就增加一格，用UP, DOWN, LEFT, RIGHT控制蛇頭的運動，而蛇身子跟著蛇頭走，每後一格蛇身子下一步走到上一格蛇身子的位置，以此類推。

(3)c語言貪吃蛇關鍵擴展閱讀：
實現邏輯
1，可以設置游標，就能實現制定位置列印製定符號。
2，涉及一個結構體，包含兩個元素坐標元素和一個結構體指針。
3，結構體串聯形成鏈表，遍歷獲取成員坐標，列印符號得到蛇身。
4，不斷的加頭，去尾，重新遍歷坐標，再列印形成蛇的移動。
5，食物產生的位置判定，不能越界，也不能與蛇身體重合。
6，蛇的轉向判定，一條規則，不允許倒退。
7，轉向的實現，跟行進方向決定新的關節坐標（當前頭的上下左右）
8，死亡檢測，是否頭節點坐標是否與牆壁重合，是否與身體其他關節重合。
9，加速減速，設置刷新休眠時間實現。
Ⅳ c語言貪吃蛇的速度控製程序怎麼編
可以Sleep函數設置延時來控制貪吃蛇的速度。
函數名： Sleep
功 能： 執行掛起一段時間
用 法： void Sleep(DWORD dwMilliseconds);
在VC中使用帶上頭文件
#include <windows.h>
（ Sleep函數存放頭文件：WinBase.h）
在gcc編譯器中，使用的頭文件因gcc版本的不同而不同
#include <unistd.h>
Sleep()單位為毫秒，sleep()單位為秒（如果需要更精確可以用usleep單位為微秒）
返回值
若進程/線程掛起到參數所指定的時間則返回0，若有信號中斷則返回剩餘秒數。常式：

Ⅳ C語言貪吃蛇移動
for(i=snake.node-1;i>0;i--)/*蛇的每個環節往前移動,也就是貪吃蛇的關鍵演算法*/
{
snake.x[i]=snake.x[i-1];
snake.y[i]=snake.y[i-1];
}
注釋已經解釋的很清楚了，不知道你還要問什麼？
Ⅵ c語言貪吃蛇怎麼讓蛇自己動起來啊
死循環+Sleep可以完成這個功能的
比如說我現在定義了一個小方塊，讓他自動移動
int i,j;
int a[25][80]={0};
//用數組來覆蓋整個運行界面
int x=10,y=0;
//定義一個x,y表示方塊當前的位置
while(1)
{
//清楚之前的輸出信息
system("cls");//這是調用的命令行，作用是清屏
a[x][y]=1;
//數組元素為1就表示在界面上的這個位置顯示方塊
//在屏幕上相應位置輸出方塊
for( i = 0; i<25 ; i++)
for( j=0; j<80 ;j++)
if(a[i][j]==0) printf(" ");
//等於0就表示該位置不是方塊，輸出一個空格
else printf("%c",2);
//否則就輸出這個方塊
//然後重置這個數組，這個可以和上一個循環合並在一起
for( i = 0; i<25 ; i++)
for( j=0; j<80 ;j++)
a[i][j]=0;
// 更改方塊所在的位置
//向上 x=x-1;
//向下 x=x+1;
//向左 y=y-1;
//向右 y=y-1;
//上面的四句保留一句就可以了
//然後休息休息
Sleep(300);
}
基本演算法就如代碼所示
具體的肯定和你向做的效果不一樣
比如說你要控制蛇的方向
那改變位置的時候就需要判斷
而且，改變一條蛇和改變一個方塊也不一樣
不過總體思路是這樣子的
僅作參考
注意一點，Sleep函數是window頭文件裡面的
需要導入window頭文件
如果不是Windows系統，請替換為相應的函數
