I wrote a custom font code i wanted some feed back on
before i past it, i need to make some info clear on how it works
first I use a simple bitmap (.BMP) to hold the characters along with a little data in the bitmap about the font
at point 0,0 in the bitmap is a pixil representation of the width in pixils the space character is(it would be silly to have this value over 10), and at point 1,0 (there should be at most 70-90 characters in a full alpha-numeric list, inlcuding punctuations and mathmatic symbols) is the number of characters that are in the font +1 (I know theres a flaw in the codes somewhere or this number would just be a count of characters)
now there needs to be a support file that also has all characters used in the font surrounded by double perentheses ("), such as " ABC" in the order that it appears in the bitmap...
now that I've explained the setup here are the subs and what they do
SUBS
setfontfile( file as string)- this will change the fontlist to what is placed in file
load(file as string)- loads the font bitmap for file
fontcolor( r as integer, g as integer, b as integer)- sets color to rgb
fontcolor( c as integer) - makes font color of c
txt( t as string, x as single,y as single) - puts t at x,y on screen
screen 19,,,1
DIM as fonts font
font.setfontfile( <FONTLIST> )
font.load( <BITMAP> )
font.txt( "Your text goes here", 0,100)
-----------"FONT.FNT"-------------------
" ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789.!?,':-+*/=()"
----------TO MAKE A QUICK FONT BITMAP---------
I use a paint program called ultimate paint which has a palette function on it and saves in 8 bit formats using the palette chart which makes this really easy, I type the characters down first in note pad and then in the paint editor using palette color 255 (the color i've reserved for font) on a black (0) background, then i figure out howmany pixils are from the start of the bitmap to the first character and place the color of that value (10 pixiles= color 10) at coor(0,0) followed by the number of characters+1 at coor(1,0), i save the note pad file as "FONT.FNT" and save the bitmap as "FONT.BMP"
well here's the code, I know there's probably better codes somewhere but
I prefer to write my own personal include files for what i code so dont bother telling me otherwise...

well that's it, go ahead and check it out and get back to me with any advice/pointers/or comments you have, I don't mind criticism but unless you can say it in a way that can get me to laugh, try to be polite
thank you.
