[RESOLVED] checking dynamic numbers in a loop...

[RobbieC]

Hi there, I'm having a bit of trouble with a script to check a 'dynamic number'...

Basically, I've got a movie which plays in a loop and each time it goes around, it clicks up a number, which I have on the stage as 'dynamic text' called "ImageNumber" - this bit is working fine it uses the following code to add:

var count:uint = count+1;
ImageNumber.text=count.toString();

I have a second 'dynamic number' called "numberOfImages" and what I need to happen, is that the 'loop' checks "numberOfImages" and when that number is reached, "ImageNumber" is reset to '0' so that the count begins again...

Probably really basic if/else statement, but I just can't get my head 'round it...

If anyone can point me in the right direction, I'd be most grateful

Thanks in advance

Well, really var count will be the equivalent of your ImageNumber, so:

if (count >= numberOfImages) {
count = 0
} 

Just watch where you put that stuff; make sure that count isn't going to change on you when you DON'T want it to.
EDIT: I suggest you put it between the two lines you just showed.

thanks Multihunter, I was thinking along that line earlier, but it comes up with an error:

1176: Comparison between a value with static type uint and a possibly unrelated type String.

numberOfImages should be datatyped to a int or uint.

var numberOfImages:uint;

if a number is contained in a string then it will stay a string until you convert it. You can convert it like this: Number(myString). That will change the number in myString to an actual number that you'll be able to use in the comparison.

Awesome stuff chaps, got it all working now

Thanks for all your help and enlightenment

Just one more thing on this topic....

Is it possible using Math.random() to set the start number between 0 and 'numberOfImages' randomly?

ie. randomize the first image that is shown, then continue as before...

[Multihunter]

Ok, so if I understand correctly, you have:

var count:uint = count+1 

looped?

You're declaring it a new variable every loop. You only need to delcare it once, so at the beginning of your code have:

var count:uint = Math.ceil(Math.random()*numberOfImages) 

then, in the loop have:

count += 1 

Which is the same as:

count = count + 1

brilliant MultiHunter to the rescue again!

Thanks for your help buddy
