pawn Код:

else if (id == playerid) return SendClientMessage( ... ); // you can't use it to yourself.

Change to:

pawn Код:

GetPlayerPos(playerid, x, y, z); // Your position

pawn Код:

else if (!IsPlayerInRangeOfPoint(id, 5.0, x, y, z)) return SendClientMessage(playerid, 0xFF0000AA, "You are not near that player");

It should work, if the id is not in range of 5 meters to the playerid's position.. then send the error message.

If you test it on yourself with comment the line about the id == playerid and it works, then it's probably working 99 percent.
