I am crating a roulette wheel dynamically. It has one movie clip for the numbers around the edge which it duplicates and positions correctly. My problem is that ever other number has a black background on it (on a real roulette wheel)

Is there a to distinguish between an odd number and an even number

Eg  
[SIZE=3][AS]  
if (i = odd )  
{  
number\_background = red  
}  
if (i = even )  
{  
number\_background = black  
}  
[/AS][/SIZE]

or something to that effect

Any help would be greatly appreciatedda:crazy:

I don’t think there is something like tha, but try this one instead

[AS]if (i/2 == Math.round(i/2)) {  
trace(“red”);  
} else {  
trace(“black”);  
}[/AS]

THATS THE ONE, Worked like a charm

I now have a full black and red (and green) roulette wheel. Thanks for that.

Faster:

```auto
if (i%2) trace ("even") ;
else trace ("odd") ;

```

pom 🙂

hahaha very nice! Tell me pom thus the modulo operator work like this:

divides the variable i with, in this case 2, and returns true when there is a remainder? :-\
