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

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:

Code:

---

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:

PHP Code:

---

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...

Ok, so if I understand correctly, you have:

PHP Code:

---

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:

PHP Code:

---

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


---

then, in the loop have:

PHP Code:

---

count += 1 


---

Which is the same as:

PHP Code:

---

count = count + 1 


---

brilliant MultiHunter :) to the rescue again!

Thanks for your help buddy
