Thread: i dont understand this bug, please help me :(

my project is to code a maze game and i decided to include some puzzle elements. my group and i decided that we would have characters that have different properties. for example, pushable characters, characters that you can only pass through once, teleporting characters etc. '$' is supposed to be the character that only allows you to pass through it once, then it will turn into '#' which is an immovable wall. however, when i use gotoxy to move to the $ character, and change it to '#', it does change but the player still can pass through it freely. >.<
The code for the change is this :

Code:

if (move == 'd' || move == 'D')
	{
		if (grid[_y][_x+1] == ' ')
		{
			gotoxy(_x, _y);
			cout << " ";
			_x++;
			gotoxy(_x, _y);
			cout << "@";
		}
		else if (grid[_y][_x+1] == '$')
		{
			gotoxy(_x, _y);
			cout << ' ';
			_x++;
			gotoxy(_x,_y);
			cout << '#';
			_x++;
			gotoxy(_x,_y);
			cout << '@';
		}
		else if (grid[_y][_x+1] == '&')
		{
			gotoxy(_x, _y);
			cout << " ";
			_x++;
			gotoxy(_x,_y);
			cout << "^";
			_x++;
			gotoxy(_x,_y);
			cout << "@";
		}
	}

more info: i have a global char grid[100][100] declared and i used strcopy to copy the text game stages into it. then printing it out with a for loop. help would be greatly appreciated! thanks!

thanks for the response, i'll change the underscore.

there is no code detecting the '#'. I didnt put a code detecting a '#' because i dont need it to do anything if the player is moving straight into a '#'. the player will just stay at the current coordinates and nothing will happen to the '#' o.o

You print a #, but you don't change the thing in the array to # (it's still $), so your future checks won't complain about it.

now that the problem is identified, how do i fix it x.x

if im not wrong, i have to go into the copied string, find the character '$', erase it and change it to '#'. but i have no idea how to do that :x

If you don't know how to do that, then how did you make the maze in the first place?

strcpy(grid[], "####################$############");

That ... might work, depending on how you set up your array, assuming you spelled strcpy correctly and didn't actually put the brackets in. Normally we use = to put things into variables.

You need to use = to change the value of a variable. Have you used = before? You put the variable you want to change on the left, and you put the value you want the variable to have on the right.

i have. i used cout because i thought it worked, but now i find out it only worked superficially. i used

Code:

grid[iy][ix] = '#';

instead and it worked. even though the symbol didn't change, the player cannot pass through the '$' sign now, as though it is actually a '#'. that's nothing a mere cout can't fix! hoho. thanks! this allowed me to proceed with my proj

cout is just a print statement, nothing more.

yeah! i notice it now. tyvm ^_^
