桌面图标贪吃蛇

闲暇之余，写了一个小游戏，因为以前用不同语言写过好几个版本的贪吃蛇，所以这次轻车熟路，只用了100行代码

实现语言：c

实现原理：链表

代码：

#include<stdio.h>
    #include<windows.h>
    #include<commctrl.h>
    #include<math.h>
    #include<stdlib.h>
    #include<malloc.h>
    #include<conio.h>
    #include<time.h>
    int head_x, head_y,food_x,food_y,length,max_length;
    char ch;//动作
    HWND H = (HWND)0x00010146;
    HWND hwnd = FindWindowEx(H, NULL, "SysListView32", "FolderView");
    typedef struct node {
    	int i;//图标序号
    	int x;//图标横坐标
    	int y;//图标纵坐标
    	struct node *pNext;
    }Node,*pNode;
    pNode CreateList();//创建链表
    void Insert_Node(pNode ,int,int,int);//插入节点
    void Move(pNode,int,int);//移动蛇身
    void MakeFood(); //产生食物
    bool Judge(pNode);//判断
    void main() {
    	//初始化
    	    max_length = ListView_GetItemCount(hwnd);
    		printf("%d", max_length);
    		for (int i = 0; i < max_length; i++)
    		{
    			SendMessage(hwnd, LVM_SETITEMPOSITION, i, MAKELPARAM(100000, 100000));
    		}
    		pNode pHead = CreateList();
    		Insert_Node(pHead, 0, 800, 800);
    		length = 1;
    		SendMessage(hwnd, LVM_SETITEMPOSITION, pHead->pNext->i, MAKELPARAM(pHead->pNext->x, pHead->pNext->y));
    		MakeFood();
    	//进入游戏
    		while (1) {
    			if (_kbhit()) {
    				ch = _getch();
    			}
    				 head_x = pHead->pNext->x;
    				 head_y = pHead->pNext->y;
    				if (ch == 'w') {
    					head_y -= 50;
    				}
    				if (ch == 'a') {
    					head_x -= 50;
    				}
    				if (ch == 'd') {
    					head_x += 50;
    				}
    				if (ch == 's') {
    					head_y += 50;
    				}
                                    bool bo = Judge(pHead);
    				Move(pHead, head_x, head_y);
    				SendMessage(hwnd, LVM_SETITEMPOSITION, pHead->pNext->i, MAKELPARAM(pHead->pNext->x,pHead->pNext->y));
    				if (bo) {
    					MakeFood();
    					SendMessage(hwnd, LVM_SETITEMPOSITION, pHead->pNext->i, MAKELPARAM(pHead->pNext->x, pHead->pNext->y));
    				}
    				Sleep(200);
    		}
    		system("pause");
    	}
    pNode CreateList() {
    	pNode pHead = (pNode)malloc(sizeof(Node));
    	pHead->pNext = NULL;
    	return pHead;
    }
    //头插法
    void Insert_Node(pNode pHead, int i, int x, int y) {
    	pNode pNew = (pNode)malloc(sizeof(Node));
    	pNew->i = i;
    	pNew->x = x;
    	pNew->y = y;
    	pNode p = pHead;
    	pNew->pNext = p->pNext;
    	p->pNext = pNew;
    }
    void Move(pNode pHead, int x, int y) {
    	pNode p = pHead;
    	while (p->pNext != NULL) {
    		p = p->pNext;
    	}
    	Insert_Node(pHead,p->i,x,y);
    	p = pHead;
    	while (p->pNext->pNext!=NULL) {
    		p = p->pNext;
    	}
    	p->pNext = NULL;
    }
    void MakeFood() {
    	srand((unsigned)time(0));
    	food_x = (rand() % 18 + 1) * 100;
    	food_y = (rand() % 9 + 1) * 100;
    	SendMessage(hwnd, LVM_SETITEMPOSITION, length, MAKELPARAM(food_x,food_y));
    }
    bool Judge(pNode p) {
    	if (head_x == food_x && head_y == food_y ) {
    		Insert_Node(p,length, food_x, food_y);
    		length += 1;
    		return true;
    	}
    	return false;
    }

蛇的身体是由链表组成，食物是随机产生，身体成长用的是链表的头插法。

这两句代码是获取桌面图标的句柄

HWND H = (HWND)0x00010146;
    HWND hwnd = FindWindowEx(H, NULL, "SysListView32", "FolderView");

因为 win10的桌面窗口句柄没有窗口标题，只靠类名无法确定，所以用了vs自带的工具spy++强制定位转型

还有一点需要注意的是    要取消桌面的网格布局和自动排序，他会影响图标的控制和移动

然后设置自动排序就能恢复原状
