[FMX] Help working out/learning lottery script

1

Hey all,

Recently I started a thread about a lottery draw and got a good response that helped me out thanks to Adam14 and Kode.

Kode gave a basic file that included a random number draw and a ‘bank’ that payed out if lotto balls were correct.

My problem is the script is rather advanced and just passes over my head and I am still an newbie at action script, I would be very grateful if anyone could help explain/comment the script. User ‘Futureflash’ has added some parts.

The basic file is attached and script is below.

Pretty cool little game. I am working on commenting it so give me a few . . .

:hr:

Here ya go. If you still dont’ understand some of the code

  1. look stuff up in the actionscript reference in Flash
  2. ask more questions here!

:hr:

Lunatic you are a ledgend,

I hoped someone would help me out a little but that’s brilliant.
I will slowly…slowly go thru the script and work out in my head the various parts.

Thanks a million for taking the time to help me out, the game is cool but I didnt understand the script workings, so now I can sleep at night…lol

lol, no problem daboz. Good luck getting through it - there was one line of code that I didn’t get. I’m gonna post it here and hopefully someone (HEY SCOTTY! HINT HINT) will jump on it and translate it for us . . .

:hr:

Okay here it is, and it is within a great big for loop:


for (index=0, total=0; index<output.length; index++) {
//yadda yadda yadda
**total += input[index].text == numbers[ran];**
//yadda yadda yadda
}

total = total + input[index].text but only when input[index].text is (comparatively) equal to numbers[ran]?

Is this like a shorthand if statement? Does anyone know?

total = a variable that tracks the number of correct guesses
input[index] = the array of numbers input by the user
numbers[ran] = the array of randomly generated numbers created by the program
output = an array of dynamic textboxes that display the randomly generated numbers

I heard a princess shout for help, so I took my horse to find what was wrong=)

total += input[index].text == numbers[ran];

I think you’re right (I’m not completely sure) that it’s a sort if statement:
if numbers[ran] (the random number) equals the input number, so is true (equals 1) , add 1 to total.
Hope this makes sense;)
