运动问题，跳过字段

Question

我正在制作一个游戏，其中您（玩家）由2D矩阵中的数字表示。问题是，当我移动播放器时，它会跳过字段，并且反应不佳。运动非常不准确。如果可以运行该程序，则可以更好地理解该问题。我该如何解决这个问题？

#include <stdio.h>
#include <windows.h>
#include <time.h>

void delay(unsigned int mseconds)
{
    clock_t goal = mseconds + clock();
    while (goal > clock())
        ;
}

int map[5][5] = {{0, 0, 0, 0, 0},
                 {0, 0, 0, 0, 0},

                 {0, 0, 0, 0, 0},
                 {0, 0, 0, 0, 0}};

int mUpdate(int x)
{
    int i, j;
    for (i = 0; i < 5; i++)
