我是c ++的初学者,我正在编写一个名为dungeoncrawl.cpp的程序。
所以对于程序的第一部分(地图生成和随机位置)到目前为止这么好,但是对于运动机制我发现了一个问题。是的我到目前为止只添加左右,但程序似乎只能识别switch语句中的第二种情况,例如当我按'd'时,播放器向右移动,但是当我按'a'时没有任何反应,如果我改变案件的顺序,则会发生相反的情况。我很确定我可以使用if语句使其工作,但我很好奇。谢谢您的帮助。

// dungeoncrawl.cpp
// Make a program that outputs a simple grid based gameboard to the screen
// using either numbers or characters.
// Allow the user (marked by G in the example) to move either up, down, left,
// or right each turn.
// If the player steps on a trap then they lose. If the make it to the
// treasure 'X' then they win.
int i;
char table[76];
class game {
public:
void board() { // GAME BOARD
srand(time(0));
for (i = 0; i <= 76; i++) {
if (i % 11 == 0) {
table[i] = '\n';
} else {
table[i] = '.';
}
}
// ENEMIES
for (int x = 0; x < 3; x++) {
i = (rand() % 75);
if (table[i] != '\n' && table[i] != 'G' && table[i] != 'X' &&
table[i] != 'T') {
table[i] = 'T';
} else {

你没有足够的break语句,你所拥有的休息是在for循环中并且突破了
试试这个:
case 'a':
for (i=0;i<=76;i++){
if (table [i]=='G') {
table [i]='.';
table [i-2]='G';break;}
}
break;
case 'd':
for (i=0;i<=76;i++){
if (table [i]=='G') {
table [i]='.';
table [i+2]='G';break;}
}
break;
