当我按向上箭头键时，一颗星向上移动2次但是我想在第一次和第二次移动的星之间加一个延迟，这就是代码：
#include <iostream>
#include <windows.h>
using namespace std;
char Map[10][20] = {"###################",
"#### #########!#",
"#### # ######### #",
"####* # ######### #",
"# # ######### #",
"# ##### ######### #",
"# ##### ######### #",
"# ##### ######### #",
"#@##### #",
"###################" };
int Gamespeed = 100;
int Level = 1;
bool stopgame = false;
int Hp = 100;
int MaxHp = 100;
int main()
{
while(stopgame == false && Level == 1)
{
system("cls");
for (int y = 0; y < 10; y++)
{
cout << Map[y] << endl;
}
cout << "Hp: "<< Hp << "/" << MaxHp << endl;
for (int y = 0; y<10; y++)
{
for(int x = 0; x<20; x++)
{
switch(Map[y][x])
{
case '#':
{

}
break;
case '*':
{
if (GetAsyncKeyState(VK_UP) != 0)
{

y -= 1;
Map[y][x] = '*';
}
Sleep(1000);
if (y = 2)
{
Map[y][x] = ' ';
y -= 1;
Map[y][x] = '*';
}
}
}
break;
case '@':
{
if (GetAsyncKeyState(VK_UP) != 0)
{
int y2 = (y-1);
switch(Map[y2][x])
{
case ' ':
{
Map[y][x] = ' ';
y -= 1;
Map[y2][x] = '@';
}break;

switch(Map[y][x2])
{

{

}break;
case '!':
{

}break;
case '*':
{

Map[y][x2] = '@';
}break;
}
}
if (GetAsyncKeyState(VK_LEFT) != 0)
{
int x2 = (x - 1);
switch(Map[y][x2])
{
case ' ':

Map[y][x] = ' ';
x -= 1;
Map[y][x2] = '@';
}break;
}
}
}
}
}
}
Sleep(Gamespeed);
}
这是使星星移动的代码
case '*':
{
if (GetAsyncKeyState(VK_UP) != 0)
{
if (y = 3)
{
Map[y][x] = ' ';
y -= 1;
Map[y][x] = '*';
}
Sleep(1000);
if (y = 2)
{
Map[y][x] = ' ';
y -= 1;
Map[y][x] = '*';
}
}
}
break;
问题是睡眠暂停整个程序而不是明星移动

答案 0 :(得分：0)
让我猜一下，这是一个窗口程序（带有GetMessage / DispatchMessage循环），对吧？在这里，你永远不应该使用Sleep（）或任何其他长时间运行来阻止。这会冻结整个UI，因为没有键盘输入或重绘之间发生。你可以做什么取决于你的设计，但一个简单的方法是触发一个计时器，该计时器将在稍后调用窗口过程以及你可以完成移动的位置。
另一种方法是使用线程，但那些具有完全不同的复杂性。另一个替代方案是我相信一个睡眠函数可以提供消息队列，这可以避免冻结 - 你必须检查文档中该函数的名称是什么。
