how to move character in maze

[ccwash]

My question is:
I have to write a game that allows the user to navigate through a maze. I have written most of the code but am stuck at this function:
moveCharacter-move the user's character to a different location in the maze. The character can only move up, down, left and right and can quit.
Now I think I have to use getch(), but I'm not sure how to write when the user is going up, down, left and right. Any suggestions? Thanks.

Here is a program I wrote a little while back. It's simulating an active interface with gotoxy(). It should solve your problem. I hope you are using a GCC compiler. Otherwise I could edit it for you.

Need more information please. Are you having trouble graphically moving the character? Getting the input to move the character(getch)? Testing for wall collision?

well heres what i have so far...

void moveCharacter()
        char x;
	char charPos='*';
	x= getch();

	if(x=='w')
	{
		charPos -=1;
	}

* is the character, this is the code i wrote to when the user wants to go up..not sure if this is right.....not sure how to write for down, left and right

This is vague, but so is your post.

bool DoMove(int iYOffset,int iXOffset)
{
  //Calculate new player position
  UINT iRow=Player.y+iYOffset;
  UINT iCol=Player.x+iXOffset;

  //Bounds check
  if (iRow<0 || iRow>maxrows || iCol<0 || iCol>maxcols) return false;

  //Compute new offset in maze
  UINT mazeoffset=iRow*mazewidth+iCol;

  //Bounds check
  if (mazeoffset>0 && mazeoffset<mazetotalsize)
  {
     //Check if maze cell is empty
     if (Maze[offset]==MAZE_EMPTY) 
     { 
       Maze[offset]=MAZE_PLAYER;
       return true;
     } else return false;
  } 
  return false;
}

Pass the desired offset to the function. Return true on success and false on error. MAZE_EMPTY can be 0 or any value you want. MAZE_PLAYER can be 1, 2 , etc. MAZE_WALL should be another value to represent a wall.

Get the key input from the player, set the offsets and call DoMove() with the offsets.
