关于#c语言#的问题：字符离开当前位置后使得当前的位置符号变回原来的符号例如：F向下移动后，F的原本位置变成空白或者变成x，F原本位置的t重新出现
如何实现交换位置后，字符离开当前位置后使得当前的位置符号变回原来的符号
例如：F向下移动后，将t覆盖了，F的原本位置变成空白或者变成x，然后F在向下移动，F原本位置的t重新出现，F把~覆盖了。
w , s, a ,d的代码应该如何改
代码如下：
#include
#include
#define ROW 11 //游戏区行数
#define COL 11 //游戏区列数
char map[ROW][COL] = {
{'F', 'x', 'x', 'x', 'x', 'x', 'x', 'x', 'x', 'x'}, //x为草坪
{'t', '~', '~', '~', '~', '~', '~', '~', '~', '~'}, //~为水流
{'~', '~', '~', '~', '~', '~', '~', 't', '~', '~'}, //o为终点
{'~', '~', '~', '~', '~', '~', '~', '~', '~', '~'}, //T为乌龟的位置
{'~', 't', '~', '~', '~', '~', 't', '~', '~', '~'},
{'~', '~', '~', '~', '~', '~', '~', '~', '~', '~'},
{'~', '~', '~', '~', '~', '~', '~', '~', '~', '~'},
{'~', '~', '~', 't', '~', 't', '~', '~', 't', '~'},
{'~', '~', '~', '~', '~', '~', '~', 't', '~', '~'},
{'~', '~', '~', '~', '~', '~', '~', '~', '~', '~'},
{'x', 'x', 'x', 'x', 'x', 'x', 'x', 'x', 'o', 'x'}
};
int main() {
int i, j;
int x = 0, y = 0;
char c, q;
while (1) {
for (i = 0; i < ROW; i++) {
for (j = 0; j < COL; j++) {
printf("%c ", map[i][j]); //生成游戏界面
}
printf("\n");
}
printf("请输入操作：\n");
scanf("%c", &c); //w s a d
getchar(); //防止重复出现的二维数组
system("cls"); //清理屏幕
if (c == 'w') {
q = map[x - 1][y];
map[x - 1][y] = map[x][y];
map[x][y] = q;
x = x - 1;
}
else if (c == 's') {
q = map[x + 1][y];
map[x + 1][y] = map[x][y];
map[x][y] = q;
x = x + 1;
}
else if (c == 'a') {
q = map[x][y - 1];
map[x][y - 1] = map[x][y];
map[x][y] = q;
y = y - 1;
}
else if (c == 'd') {
q = map[x][y + 1];
map[x][y + 1] = map[x][y];
map[x][y] = q;
y = y + 1;
}
else if (c == 'l') {
int a, b;
printf("添加浮木：请输入浮木放置的横坐标和纵坐标\n");//添加浮木
scanf("%d%d", &a, &b);
getchar();
map[a][b] = 'L';
}
else if (c == 'k') {
int a, b;
printf("清除浮木:请输入需要清除浮木的横坐标和纵坐标\n");//清除浮木
scanf("%d%d", &a, &b);
getchar();
if (map[a][b] == 'L') {
map[a][b] = '~';
} else if (map[a][b] == '~' || map[a][b] == 'F' || map[a][b] == 't' || map[a][b] == 'x') {
printf("该位置没有浮木");
}
}
else if (c == 'b') {
int a, b;
printf("请输入臭虫放置的横坐标和纵坐标\n"); //添加臭虫
scanf("%d%d", &a, &b);
getchar();
if (map[a][b] == 'L') {
map[a][b] = 'B';
} else if (map[a][b] == '~' || map[a][b] == 'F' || map[a][b] == 't' || map[a][b] == 'x')
printf("臭虫没有放在浮木上\n");
}
}
return 0;
}
如何实现不是简单的交换位置
那你不能直接修改这个数组
你应该分为两部分，一个数组是作为底图的，它永远不变，或者至少是基本不变，另一个是把各种可移动物体叠加上去之后的样子
最终显示的是数组2
而每次移动后，你需要重新用数组1和可移动物体生成数组2
否则你的可移动物体把底图信息给覆盖了就找不回来了
