Search/highlight a random line of text?

[N64Mario]

So, say I have a text file (that can be edited) with the following:
Line 1
Line 2
Line 3
I would add a "random' button on the tool. It would pick a random line from 1 - 3, and highlight it.

If I were to add on to the list like so:
Line 1
Line 2
Line 3
Line 4
Line 5
Line 6
I would want to pick a random line from 1 - 6, and highlight it.

I also would like to have the option where if it detects a space in between each new line, to NOT register it, like so:
Line 1

Line 2

Line 3

Line 4
To skip to another line if there is no text written there, but still select a random line and highlight it.

What would I need to do to go about this? Do I need variables to detect the # of lines, or a construction of code to read certain text?

Is there a reason you allow empty lines? If you didn't allow that this is very easy.

If the text file is loaded into a list object (and the text file has blank lines) I would have a separate list object for loading the raw text file. Then transfer the non-empty lines one at a time to your final list object.

Or you could just run a loop on the raw list object line by line, check if the line equals the string " " ( empty) and delete the line if it is.

Hopefully you don't need to retain empty lines.

Thanks for your suggestion, it help me

Well, I suppose empty lines are not necessary then. Also, there isn't a list object being used. It's just a plain, simple text file, if that makes any difference. Though maybe a list object would be better? I don't know, because what I am doing is the text file contains a list of submitted number ID's recorded.

I can't think of an easy way for you to read "lines" from a text file loaded into a string object or Alterable string. It will be simpler to work with the text if you load it into a list. I guess you could load it into an array and do the same pruning procedure I mention above, but Lists make it human readable.

It just sounded like the player is going to be encouraged to open and edit the text file that Fusion will be reading from. And that is never a good idea unless you force them to use a specific syntax and format.
