Solved BasePlayer.Find error

Code:

[ChatCommand("test")]
        void FindPlayer(BasePlayer player)
        {
            var targetPlayer = BasePlayer.Find("steamid");
            if (targetPlayer.IsConnected())
            {
                //targetPlayer is online
            }
            else
            {
                //targetPlayer is offline
            }
        }

I think this should work, but it does'nt.

Code:

public static BasePlayer Find(string strNameOrIDOrIP)

You're not searching for anyone.

Code:

var targetPlayer = BasePlayer.Find("Reynostrum");
var targetPlayer = BasePlayer.Find("12345678987654321");
var targetPlayer = BasePlayer.Find("127.0.0.1");

 

Sorry, I don't follow, I am new with C#

Code:

var targetPlayer = BasePlayer.Find("12345678987654321");

That's what I am doing, but what's wrong?

 

It will return null if nothing found, so make sure it's not null

 

Code:

void FindPlayer(BasePlayer player)
        {
            var targetPlayer = BasePlayer.Find("steamid");
            if (targetPlayer != null)
            {
                if(targetPlayer.IsConnected())
                {
                    //online
                }
                else
                {
                    //offline
                }
            }
            else
            {
                //offline
            }
        }

Something like this?

 

Really if it's not null, they're online
