How do I find my corresponding array entry?

Hi,

I have a 2D array that contains a list of UIDs in row 1 and a flag in row2

I pick a random line, do stuff with the UID and delete the line

and then I want to find that other line that has the same flag to remove it as well

could look something like this:

UID Flag

41 0

45 0

50 1 <- randomizer might pick this line for example

53 1

59 2

62 2

how do i find and remove the other ones that are flagged the same?

my approach was to go:

array>for each X element

compare: value at (loopindex,1) = pickedFlag

action: delete row (loopindex) from X axis

but I doesn't seem to work

Try

System: For "" from Array.Width - 1 to 0

Array: Value at (loopindex, 1) = pickedFlag ---> Array: Delete index loopindex from X axis

edit: I rarely use Array: For Each. Maybe it's just personal preference.

Also I'm not sure what you meant by "action : delete row (loopindex)". You never wanted to delete a row, just a column. Remember C2 debugger shows the axes switched 90 degrees, so rows look like columns and vice-versa. I'm going backwards in the above code because if you modify the array you're currently iterating, you'll skip a column when the array gets shorter by 1 column.

guess we're talking about the same thing, what i want to delete is the line with the picked UID and its flag.

thanks for elaborating, wasn't sure you meant what i thought you meant seems to be working now, thanks!

Glad it helped. I was just trying to say that you're deleting columns, not rows (lines)

Your array actually looks like this:

41, 45, 50, 53, 59, 62
0,  0,  1,  1,  2,  2[/code:10gegxz7]
