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;
				}
				Move(pHead, head_x, head_y);
				SendMessage(hwnd, LVM_SETITEMPOSITION, pHead->pNext->i, MAKELPARAM(pHead->pNext->x,pHead->pNext->y));
				bool bo = Judge(pHead);
				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+50) == food_y&&ch=='s')|| (head_x == food_x && (head_y-50) == food_y&&ch=='w')|| ((head_x - 50) == food_x && head_y == food_y && ch == 'd') || ((head_x-50) == food_x && head_y == food_y&&ch=='a')) {
		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
