Thread: Overwriting all in array, why?

Bugging the life out of me. I'm searching through an array (board) looking for patterns that match what's in bends[][][][]

Code:

enum Direction bends[NUMBENDS][2][2][2] = {      /* [type][before/after][y][x]*/
{{{ NONE, DOWN},{ NONE,  END}},{{ DOWN, LEFT},{RIGHT,  END}}},
{{{ NONE, NONE},{  END, LEFT}},{{ DOWN, LEFT},{  END,   UP}}},
{{{  END, NONE},{   UP, NONE}},{{  END, LEFT},{RIGHT,   UP}}},
{{{RIGHT,  END},{ NONE, NONE}},{{ DOWN,  END},{RIGHT,   UP}}},
{{{ NONE,  END},{ NONE,   UP}},{{RIGHT,  END},{   UP, LEFT}}},
{{{ NONE, NONE},{RIGHT,  END}},{{RIGHT, DOWN},{   UP,  END}}},
{{{ DOWN, NONE},{  END, NONE}},{{RIGHT, DOWN},{  END, LEFT}}},
{{{  END, LEFT},{ NONE, NONE}},{{ END, DOWN},{   UP, LEFT}}}
};

...skipping to the problem bit ...

    index = 0;
    for (xy = 0; xy < (MAX * MAX) - MAX; xy++) 
    {
      if ((xy + 1) &#37; MAX == 0) continue;

      for (c = 0; c < NUMBENDS; c++) 
      {
        if ((bends[c][0][0][0] != END) && (bends[c][0][0][0] != board[xy])) continue;
        if ((bends[c][0][0][1] != END) && (bends[c][0][0][1] != board[xy + 1])) continue;
        if ((bends[c][0][1][0] != END) && (bends[c][0][1][0] != board[xy + MAX])) continue;
        if ((bends[c][0][1][1] != END) && (bends[c][0][1][1] != board[xy + MAX + 1])) continue;

        mods[index][0] = xy; mods[index][1] = c; index++;
for (d = 0; d < index; d++) mvprintw(debug++,40,"InBends%d:%d,%d",d,mods[d][0],mods[d][1]);refresh(); /*debug output*/
      }
    }

I added a debugging loop there to output the array as it find it, and I'm getting some odd output. I'd expect it to show me a building array, but instead I get something like:

Code:

InBends0:27,4
InBends0:29,6
InBends1:29,6
InBends0:37,7
InBends1:37,7
InBends2:37,7

See how every time the array builds all previous entries are overwritten by the last one. Why? The loops and conditionals all look good to me. The problem is definately within those bracket, but I can't, for the life of me, figure out where.
