TCC错误:索引太大

Question

我一直在玩光线投射，并决定使用3D阵列来制作级别，然而TCC却说出了这一点：

M_MAIN.C:19: error: index too large

数组的大小是否有限制？代码：

#define MAP_01_WIDTH 8
#define MAP_01_HEIGHT 8
#define MAP_01_DEPTH 8
#define MAP_01_PLAYER_START_X 2
#define MAP_01_PLAYER_START_Y 2
#define MAP_01_PLAYER_START_Z 2

char MAP_01[MAP_01_WIDTH][MAP_01_DEPTH][MAP_01_HEIGHT] =
{
    { {1, 1, 1, 1, 1, 1, 1, 1}, {1, 0, 0, 0, 0, 0, 0, 1}, {1, 0, 0, 0, 0, 0, 0, 1}, {1, 0, 0, 0, 0, 0, 0, 1}, {1, 0, 0, 0, 0, 0, 0, 1}, {1, 0, 0, 0, 0, 0, 0, 1}, {1, 0, 0, 0, 0, 0, 0, 1}, {1, 1, 1, 1, 1, 1, 1, 1} },
    { {1, 0, 0, 0, 0, 0, 0, 1}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {1, 0, 0, 0, 0, 0, 0, 1} },
    { {1, 0, 0, 0, 0, 0, 0, 1}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {1, 0, 0, 0, 0, 0, 0, 1} },
    { {1, 0, 0, 0, 0, 0, 0, 1}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {1, 0, 0, 0, 0, 0, 0, 1} },
    { {1, 0, 0, 0, 0, 0, 0, 1}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {1, 0, 0, 0, 0, 0, 0, 1} },
    { {1, 0, 0, 0, 0, 0, 0, 1}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {1, 0, 0, 0, 0, 0, 0, 1} },
    { {1, 0, 0, 0, 0, 0, 0, 1}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {2, 0, 3, 0, 0, 4, 0, 2}, {1, 0, 0, 0, 0, 0, 0, 1} },
    { {1, 0, 0, 0, 0, 0, 0, 1}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {2, 0, 0, 0, 0, 0, 0, 2}, {1, 0, 0, 0, 0, 0, 0, 1} },
    { {1, 1, 1, 1, 1, 1, 1, 1}, {1, 0, 0, 0, 0, 0, 0, 1}, {1, 0, 0, 0, 0, 0, 0, 1}, {1, 0, 0, 0, 0, 0, 0, 1}, {1, 0, 0, 0, 0, 0, 0, 1}, {1, 0, 0, 0, 0, 0, 0, 1}, {1, 0, 0, 0, 0, 0, 0, 1}, {1, 1, 1, 1, 1, 1, 1, 1} }
};

Answer 1

定义大小为8x8x8的数组，但使用9x8x8元素初始化数组。用以下方法确定大小：

#define MAP_01_WIDTH 9

或者更好的是，让编译器计算一下：

char MAP_01[][MAP_01_DEPTH][MAP_01_HEIGHT] = {...};
