Check if a certain player is online?

[LuanIllogical]

Hi! I'm starting out on plugins and I wanted to know if there's a way to check if a specific player/user is online.

Thanks in advance!

You would do so by looping over all player indexes (0 to Terraria.Main.maxPlayers) and pulling an object from TShock.Players for each of those indexes and seeing if it has the properties you want:

for(int i = 0; i < Main.maxPlayers; i++)
{
    if(Main.players[i].active)
    {
        var tp = TShock.Players[i];
        //do check logic here
    }
}

note this is typed up on the spot and might not be fully correct, but the general rule of thumb is to check TShock.Players, either by using a forloop over player indexes or using some sort of LINQ extension like .Where() or .Single()

Thanks! The "check logic" would be checking the player's name or what? (Sorry if this is an obvious question I'm just starting out.)

Well, that's up to you - "check logic" is what you want to use to check if the player is the one you're looking for: So, maybe a name, username, IP, health check - whatever you think is necessary :p
