i -1 was about the letter indexes for the string. I am sure to keep the fist point drawn at x you have to subtract 1 from i to make a zero offset from x otherwise you will be a whole column right of where you need that first draw point.
Anyway, honestly maybe the -1's might not be necessary. Mathologically sometimes you need a -1 and sometimes you don't. A screen with 0,0 top, left corner has bottom right corner at _width -1, _Height -1
If x, y is top, left corner add width, height for bottom right or add width -1, height -1?
Best way to tell is try both. I just tried with the -1's and didn't see any problems.
I think our letter boxes would overlap without the -1's. That is if we outlined the space each letter resides in as boxes, the boxes would overlap without the -1's, whereas the boxes would neatly abut one another with the -1's.
Quote:Copy / paste above has odd format above,
- L16 - The reason we use
-1
in
COLS * scale% -1
and
ROWS * scale% - 1
is because in the first iteration of the loop with
i%
being 1, if we did not subtract one, it would offset them, and so the passed in desired positions would be actually offset for the first character.
