Numbering scheme please...

Which coordinate is row and which is column in the $map[] array that will be passed to our method?

Where a '*' is some room/wall/corr block, and '-' is nothing important, is the numbering scheme:

A) - $map[row,column]

00,00------00,49
---**********
---**********
---**********
---**********
49,00------49,49

or

B) - $map[column,row]

00,00------49,00
---**********
---**********
---**********
---**********
00,49------49,49

thanks.

Actually, it's not important for reaching the goal (=connecting all the rooms in the map).

I think the version B) is more logical, because e.g. a point in a function graph is given as (x/y), means x is the horizontal axis and y is the vertical axis.
Also if you want to plot a pixel on the screen, the first coordinate is the x and the second is y.

it really doesn't matter..
