pawn Code:

new PlayerName[MAX_PLAYER_NAME], PlayerString[MAX_PLAYERS][MAX_PLAYER_NAME];
GetPlayerName(playerid, PlayerName, sizeof(PlayerName));
format(PlayerString[playerid], sizeof(PlayerString), "%s", PlayerName);

This will store player's name for every player you use.

Once you have stored it, you can use it (example):

pawn Code:

SetPlayerName(playerid, PlayerString[playerid]);
