【C语言】飞机大战怎样控制速度

Question

如题，光标下落过快，修改speed值后仍是这样

#include<stdio.h>
#include<Windows.h>
#include<conio.h>
int height, width;
int plane_x, plane_y;//飞机位置
int bullet_x, bullet_y;//子弹位置
int score;
int flag;
void gotoxy(int x, int y) {
    HANDLE handle = GetStdHandle(STD_OUTPUT_HANDLE);
    COORD pos;
    pos.X = x;
    pos.Y = y;
    SetConsoleCursorPosition(handle, pos);
}
void hideCursor() {
    CONSOLE_CURSOR_INFO cursor_info = { 1,0 };
    SetConsoleCursorInfo(GetStdHandle(STD_OUTPUT_HANDLE), &cursor_info);
}
void start() {
    height = 18, width = 26;
    plane_x = height - 3;
    plane_y = width - 2;
    bullet_x = 0;
    bullet_y = plane_y;
    score = 0;
    flag = 0;
}
void show() {
    int i, j;
    for (i = 0;i < height;i++) {
        for (j = 0;j < width;j++) {
            if (flag) {
                break;
            }
            else if (i == plane_x && j == plane_y) {
                printf("*");
            }
            else if (i == bullet_x && j == bullet_y) {
                printf("&");
            }
            else {
                printf(" ");
            }

        }
        printf("\n");
    }
    printf("\n");
    if (plane_x == bullet_x && plane_y == bullet_y) {
        flag = 1;
        printf("GAME OVER");
    }
    else {
        printf("YOU WIN!");
    }
}
void bulletMove() {
    //控制速度
    static int speed;
    if (speed < 3) {
        speed++;
    }
    if (speed == 3) {
        if (bullet_x < height) {
            bullet_x++;
        }
        else {
            bullet_x = 0;
            bullet_y = 2 + rand() % width - 2;
        }

    }
}speed = 0;
void planeMove() {
    char input;
    if (_kbhit()) {
        input = _getch();
        if (input == 'w' && plane_x >= 1) {
            plane_x--;
        }
        if (input == 's' && plane_x< height - 2) {
            plane_x++;
        }
        if (input == 'a' && plane_y > 1) {
            plane_y--;
        }
        if (input == 'd' && plane_y < width - 2) {
            plane_y++;
        }
    }
}
int main() {
    system("color 2f");
    start();
    while (1) {
        gotoxy(0, 0);
        show();
        bulletMove();
        planeMove();
    }
}
