I recently started with sourcemod and I ran into a bit of a problem with the limited file I/O available in sourcemod plugins.
I need to store several lists (basically in categories) of int values in a file and retrieve them into several arrays or a single lookup table but I don't know how I would go about doing this correctly (as in not a horrible hack).
Any help getting me on the right track would be appreciated.
