Hi Rasecleibot,

Try running this code;
[lua]math.randomseed(os.time())

x1, y1 = math.random(1,320), math.random(1,480)
x2, y2 = math.random(1,320), math.random(1,480)

local myLine = display.newLine(x1,y1, x2,y2)[/lua]

it works thank you…
what this do :math.randomseed(os.time())

And if i have like 2 points(a,b);
a.x = 400; a.y = 400;
b.x = 700; b.y = 100;
How i can draw the line :slight_smile: maybe the code above do it but i really don’t understand how it do it… help please and [import]uid: 138440 topic_id: 25654 reply_id: 103795[/import]

That line makes math.random random based on the time. (If you don’t use math.randomseed it will not be truly random.)

You don’t need it if you aren’t using math.radom.

For your question;

[lua]aX = 400
aY = 400
bX = 700
bY = 100

local myLine = display.newLine(aX,aY, bX,bY)[/lua]

Or;

[lua]aX, aY = 400, 400
bX, bY = 700, 100

local myLine = display.newLine(aX,aY, bX,bY)[/lua]

(Which is the same but a little neater.)
