Check for even or odd numbers?

Hey

This will be hard to explain, especially because i'm not from an english speaking country.

I have a list object with a list and want to add something to every 2nd line.

Like this:

Line1 - leave alone
Line2 - Add something
Line3 - leave alone
Line4 - Add something

I hope you understand what i mean.

Any idea on how to work that out?

Do a fast loop through the list (length/2) times then apply whatever you want to the line with index (loopindex*2)

Go through each line and check to see if the [line number mod 2 is 0] (the first line is line number 0 so the first "even" number begins with the first line). If the [line number mod 2 is 1] then that line is an odd line.

When you find the even line numbers, merely edit their data to suit your needs.

ProdigyX's solution is a much worse solution, so I went forth and created an example for you of how to actually do it.

Thanks!

How would i randomize the list?

Or move the current line up and down?

Here's an example I have of shuffling a list.
