here's a texture generator that i made... it basically looks at previous pixels and rounds them and then changes that color a small amout to create a texture...

code:

setscreen ("graphics:400;400")

const minClr := 16
const maxClr := 30
const smooth := 1
var clr : int := Rand.Int (minClr, maxClr)

for x : 1 .. maxx
    clr += Rand.Int (-smooth, smooth)
    clr := min (maxClr, max (clr, minClr))
    drawdot (x, 1, clr)
end for

for y : 2 .. maxy
    for x : 1 .. maxx
        if x = 1 then
            clr := whatdotcolor (x, y - 1)
        elsif x = maxx then
            clr := round ((max (whatdotcolor (x, y - 1), minClr) + max (whatdotcolor (x, y - 1), minClr) + max (whatdotcolor (x - 1, y - 1), minClr)) / 3)
        else
            clr := round ((max (whatdotcolor (x, y - 1), minClr) + max (whatdotcolor (x, y - 1), minClr) + max (whatdotcolor (x - 1, y - 1), minClr)) / 3)
        end if
        clr += Rand.Int (-smooth, smooth)
        clr := max (minClr, min (clr, maxClr))
        drawdot (x, y, clr)
    end for
end for

Funky Very Happy, at first it looks like a closeup of a tree, then if you change the max and min colors it looks great, like all neonish and stuff.

another awesome one from zylum!!! you should start c or blitz, you would do really well.

i was tinkering around with it and came up with this (not much different) :

code:

setscreen ("graphics:300;100")

var minClr := 61
var maxClr := 103
var contrast := 0.55

put "what is the smallest colour?"
get minClr
put "what is the largest colour?"
get maxClr
put "what is the contrast? (>=0)"
get contrast

setscreen ("graphics:100;100")

var clr : real := Rand.Int (minClr, maxClr)

for x : 1 .. maxx
    clr += Rand.Real * (2 * contrast) - contrast
    clr := min (maxClr, max (clr, minClr))
    drawdot (x, 1, round (clr))
end for

loop
    for y : 2 .. maxy
        for x : 1 .. maxx
            if x = 1 then
                clr := (whatdotcolor (x, y - 1) + whatdotcolor (x + 1, y - 1)) / 2
            elsif x = maxx then
                clr := (max (whatdotcolor (x, y - 1), minClr) + max (whatdotcolor (x - 1, y), minClr) + max (whatdotcolor (x - 1, y - 1), minClr)) / 3
            else
                clr := (max (whatdotcolor (x - 1, y), minClr) + max (whatdotcolor (x, y - 1), minClr) + max (whatdotcolor (x + 1, y - 1), minClr) + max (whatdotcolor (x - 1, y - 1), minClr)) / 4
            end if
            clr += Rand.Real * (2 * contrast) - contrast
            clr := max (minClr, min (clr, maxClr))
            drawdot (x, y, round (clr))
        end for
    end for
end loop


the contrast value can now be a real number rather than just an integer... also, the program loops and slightly changes each time

Looks great, but any practical use?

yes it creates textures.
