I do not think he wants to use it for permanent storage; all he said was that he needed to store temporary information through a map change. Which means there is only going to be data saved for the players on the server at the time. Depending on what he needs it for, I would wipe the file before every map change, and then add the stuff you want to add to it.

If you wanted more specific help you need to give more details about what you are saving and how you want to save it.

I am sure both userid and index do not change on mapchange.

You would be wrong ElooKoN. Here's a copy/paste from the wiki!

Originally Posted by DAT WIKI Client and Entity Indexes One major point of confusion with Half-Life 2 is the difference between the following things: Client index Entity index Userid The first answer is that clients are entities. Thus, a client index and an entity index are the same thing. When a SourceMod function asks for an entity index, a client index can be specified. When a SourceMod function asks for a client index, usually it means only a client index can be specified. A fast way to check if an entity index is a client is checking whether it's between 1 and GetMaxClients() (inclusive). If a server has N client slots maximum, then entities 1 through N are always reserved for clients. Note that 0 is a valid entity index; it is the world entity (worldspawn). A userid, on the other hand, is completely different. The server maintains a global "connection count" number, and it starts at 1. Each time a client connects, the connection count is incremented, and the client receives that new number as their userid. For example, the first client to connect has a userid of 2. If he exits and rejoins, his userid will be 3 (unless another client joins in-between). Since clients are disconnected on mapchange, their userids change as well. Userids are a handy way to check if a client's connection status has changed. SourceMod provides two functions for userids: GetClientOfUserId() and GetClientUserId().

Edit: It seems Powerlord is correct, userids no longer chance on disconnect. Perhaps OrangeBox changed the functionality?

[Powerlord]

Fine, I set up a plugin to log data on this and will report back later on my findings of whether client indexes change on map changes. I don't need to check if userids change, because I already know that they don't.

[Powerlord]

Here's my test data, taken from the attached plugin.

Powerlord is my fast desktop
rbemrose is my slow laptop

rbemrose was intentionally connected first to test if client indexes would be reordered during the first map change. And so I could kick it before the second map change.

rbemrose was kicked during ctf_doublecross.

As you can see, after the last map (ctf_2fort) started, the only connected client indexes were Replay at index 1 and Powerlord at 3.

So, to reiterate, client indexes are kept across map changes, as are userids... and "DAT WIKI" really needs to be updated because it's blatantly wrong. In retrospect, I probably should have logged the kick in here as a kick instead of just a disconnect (whoops).

[pilger]

I guess this close the case.

Thanks Powerlord, I'd do that myself but I'm swamped with work for the next couple of weeks.

Of course they are. Tons of plugins rely on that.

Yes, they do, but up until I went and edited the wiki page, it claimed they changed between maps.
