Hi :) I need a little help
.
graph.put(x,y, g.black) produce a black dot in x,y location but I need something more and I dont know how to solve this:
.
c1=math.random()*1
c2=math.random()*1
c3=math.random()*1
color=[c1,c2,c3]
graph.put(x,y, color)
.
So, I need to produce a random color, but last line above always draw a black dot (for example).
Is any way to change my variable "color" to hex ? Or maybe is another method to do this :) ?
.

As easy as an ABC ;) [Here was something not true ;p] Hex: Link <- if you looked here, you would see there is a way to use hexadecimal values. In short: colour = 0xRRGGBB. PS Pisze się "Is _there_ any way [...]" ;p

This is not helping me.
Command graph.put() recognize only a color in hex format, so table ( g.put(x,y, [c1,c2,c3]) ) do not produce a random color . If we use this table as graph.pen([c1,c2,c3]) then color become a random.. But how to solve this ?
Ps: programujesz coś w m ? ;) to dawaj gg :D

I guess you're right! Documentation says it should work, but it's not so we have a bug ;)

Try this: Code:/*
fill screen with randomly colored dots
*/
use graph as g, math, ui
sz=g.size();
ui.menu("rndcolor", ["exit"]);
g.bg(g.black);
g.clear()
do
g.put(math.trunc(sz[0]*math.random()),
math.trunc(sz[1]*math.random()),
math.trunc(255*math.random()) shl 16|math.trunc(255*math.random()) shl 8|math.trunc(255*math.random()));
g.show();
cmd=ui.cmd(0)
until cmd="exit" Please carefully read the documentation for graph.put(x, y, color) it says: Quote:- If color is a number, sets the pixel at (x,y) to the color color.
- If color is an array of numbers, sets the pixels from (x,y) to
(x+len(color)-1,y) to the colors in color.
