For 2. I would suggest CHandle<CBasePlayer> It will give you a safe pointer to the player that will be safe across level changes which is the only case I can think of where potential issue may arise with stale pointers. It is always very highly encouraged I think to use a Handle to the object if you need to store a pointer to it for a relatively longer period of time. CHandle will be set to NULL pointer when the object it holds is removed from the EntList.

At the moment I have: for (int i = 1; i < gpGlobals->maxClients; i++) { edict_t *pEdict = PEntityOfEntIndex(i); if (pEdict) { IPlayerInfo *playerInfo = playerinfomanager->GetPlayerInfo( pEdict ); if (playerInfo) { if (playerInfo->IsFakeClient()) continue; switch(playerInfo->GetTeamIndex()) { ... } } } } This works fine to count how many human players are on each team, but I don't know how to get the count of players who are currently joining the server (and are at the loading screen). I can't distinguish/find a way to locate the player count (playerInfo is always NULL for when there are no players, and players that are connecting, it seems). 2) Say I hold on to an edict_t* of a player, and then later on want to interact with them again. How do I know that its safe to access this pointer (can the instance ever be deleted from under me?), and also is there a way to check whether this player has actually changed (ie, is this a pointer to a server slot, and a new player has joined in their place since I last accessed the pointer)? I assume this may be the case as they appear to be re-used, and so I should probably compare the output of GetPlayerNetworkIDString() between calls on the edict_t*? 3) I noticed in Left 4 Dead that the DIALOG_MSG flag I can use to send a message via CreateMessage() does not appear on the client; I assume this is just a client bug. The menu/textbox ones work fine. 4) How can I determine the server's connection address (IP:Port). I can access the current map via gpGlobals->mapname by the look of it, but I don't see how I can retrieve the current IP:Port the server is running on. There is no console variable that has this information, so I can't appear to use cvar->FindVar() to locate it.
