For each item in array past point n...

[mrNoddy]

Hello.

Can someone help me, I'm trying to iterate through an array and perform a function for all items past point n, for this lets say point 3. So, for each item in my array at position 4+, trace 'hello'.

Dunno why I'm struggling so much.

Thanks.

You can loop through the array using i as a counter and start i at your target point, so for example:

for (var i:int = 4; i < MY_ARRAY.length; i++)
{
   //perform function
}

this will ignore the first 4 items in your array, just change the starting value of i to suit your needs

Thank you. What about if you want to get all the items before the current position?

No problem.

You can just the loop from 0 and run a check on the index value during the loop, like:

for (var i:int = 0; i < MY_ARRAY.length; i++)
{
   if(i >= 4)
  {
   //perform function
  }

}

so in the above you can perform a function on all items in your array, but also running a check to perform a function on all items indexed at 4 and above

Never mind, I simply start at 0 and use a break:

if (i == myNumber) {
break;
}

EDIT: Just saw your post, thanks again

Just a style note, because us programmers care so much about style...

for (var i:int = 0; i < MY_ARRAY.length && i < 4; i++)
{
 
 //do something
}

this makes your code a bit less cluttered and easier to read

OK, but if we are gonna clean it up I need to sort out the colour palettes. too.

What things you are doing with this Array?
