Random number

Posted by Sisra on Oct 20, 2007

Hi!
I'm very new to NodeBox and programing at all and I know what I'm asking for is a very basic task.
How can I get the random number n

n = random(10, 40)

into the text comand? This doesn't work:

n =random(10, 40)
 
fill(50,50,0,0)
font("Tahoma", 36)
align(CENTER)
text("n", 100, 100, 200)

Thanks in advance

When you wrap a string of text in quotes it is interpreted literally, i.e. the character n. What you want here is the contents of the variable named n.

So you need to do:

text(n, 100, 100, 200)

When NodeBox executes the text() command it will look up what value is contained in n and draw that to the screen.

I have tried that too and I'm getting this error in a floating window with buttons to Quit or Continue:
(ValueError: NSInvalidArgumentException - *** -[NSCFNumber length]: selector not recognized)

Here is the hole code:

size(600, 600)
colormode(CMYK, range=100)
 
n = random(10, 40)
 
fill(50,50,0,0)
font("Tahoma", 36)
align(CENTER)
text(n, 100, 100, 200)

I'm using NodeBox 1.0rc7 with Mac OS 10.3.9.
Any clue?

Ah OK. The text() command in the 1.0rc7 version doesn't automatically convert numbers to a string, so you need to do this yourself:

text(str(n), 100, 100, 200)

Now it works!
Thanks.
