貪吃蛇的編程
㈠ 如何用慧編程做貪吃蛇代碼
用慧編程做貪吃蛇代碼過程如下：
1、我們需要建立四個頭文件，然後分別設置蛇的狀態，上下左右，這是蛇能夠有方向可走的前提，然後我們再設置蛇身的節點，定義一個簡單的函數，這樣蛇的全身以及他的行走方向就弄完了。
2、貪吃蛇不能穿牆代碼。
3、第二步，一個函數這個函數的目的是貪吃蛇不能穿牆，很簡單的代碼分別設置長寬的最大位移，在內部范圍內設置為一即可通過，否則不能穿牆。貪吃蛇隨機生成一個食物。
4、設置一個隨機函數。這樣貪吃蛇代碼就做好了。
慧編程是一款面向STEAM教育領域的積木式和代碼編程軟體，基於圖形化編程開發。
㈡ c語言 貪吃蛇 程序
基本思路：
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。
#include <stdio.h>
#include <conio.h>
#include <windows.h>
#define BEG_X 2
#define BEG_Y 1
#define WID 20
#define HEI 20
HANDLE hout;
typedef enum {UP, DOWN, LEFT, RIGHT} DIR;
typedef struct Snake_body
{
COORD pos;//蛇身的位置
struct Snake_body *next;//下一個蛇身
struct Snake_body *prev;//前一個蛇身
}SNAKE, *PSNAKE;
PSNAKE head = NULL;//蛇頭
PSNAKE tail = NULL;//蛇尾
//畫游戲邊框的函數
void DrawBorder()
{
int i, j;
COORD pos = {BEG_X, BEG_Y};
for(i = 0; i < HEI; ++i)
{
SetConsoleCursorPosition(hout, pos);
for(j = 0; j < WID; ++j)
{
if(i == 0)//第一行
{
if(j == 0)
printf("┏");
else if(j == WID - 1)
printf("┓");
else
printf("━");
}
else if(i == HEI - 1)//最後一行
{
if(j == 0)
printf("┗");
else if(j == WID - 1)
printf("┛");
else
printf("━");
}
else if(j == 0 || j == WID - 1)//第一列或最後一列
printf("┃");
else
printf(" ");
}
++pos.Y;
}
}
//添加蛇身的函數
void AddBody(COORD pos)
{
PSNAKE pnew = (PSNAKE)calloc(1, sizeof(SNAKE));
pnew->pos = pos;
if(!head)
{
head = tail = pnew;
}
else
{
pnew->next = head;//新創建蛇身的next指向原先的蛇頭
head->prev = pnew;//原先的蛇頭的prev指向新創建的蛇身
head = pnew;//把新創建的蛇身作為新的蛇頭
}
SetConsoleCursorPosition(hout, head->pos);
printf("◎");
}
//蛇身移動的函數
void MoveBody(DIR dir)
{
PSNAKE ptmp;
COORD pos = head->pos;
switch(dir)
{
case UP:
if(head->pos.Y > BEG_Y + 1)

else
return;
break;
case DOWN:

pos.X -= 2;
else
return;
break;
case RIGHT:
if(head->pos.X < BEG_X + (WID - 2) * 2)
pos.X += 2;
else
return;
break;
}
AddBody(pos);//添加了一個新的蛇頭
ptmp = tail;//保存當前的蛇尾
tail = tail->prev;
if(tail)
tail->next = NULL;
SetConsoleCursorPosition(hout, ptmp->pos);
printf(" ");
free(ptmp);
}
int main()
{
int ctrl;
DIR dir = RIGHT;//初始蛇的方向是向右的
COORD pos = {BEG_X + 2, BEG_Y + HEI / 2};
system("color 0E");
system("mode con cols=90 lines=30");
hout = GetStdHandle(STD_OUTPUT_HANDLE);
printf(" ------------貪吃蛇的移動------------");
DrawBorder();
//自定義幾個蛇的身體
AddBody(pos);
pos.X += 2;
AddBody(pos);
pos.X += 2;
AddBody(pos);
pos.X += 2;
AddBody(pos);
pos.X += 2;
AddBody(pos);
pos.X += 2;
AddBody(pos);
pos.X += 2;
AddBody(pos);
//控制蛇的移動
while(ctrl = getch())
{
switch(ctrl)
{
case 'w':
if(dir == DOWN)
continue;
dir = UP;
break;
case 's':
if(dir == UP)
continue;

break;
case 'a':

}
(2)貪吃蛇的編程擴展閱讀：
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。
