I need to make the command to detect the closest player when the params aren't used, I tried this but it doesn't work.

Код:

CMD:rob(playerid, params[])
	{
	    if(sscanf(params, "U", params[0])) return SendClientMessage(playerid, ERROR, "Usage: /rob [player/id]");
     	if(params[0] == INVALID_PLAYER_ID) params[0] = GetClosestPlayerToPlayer(playerid);
	    if(GetDistanceBetweenPlayers(playerid, params[0]) >= 9) return SendClientMessage(playerid, ERROR, "No player is close to you.");
	    else
	    {
		    if(IsPlayerSpawned(playerid))
		    {
				if(gTeam[playerid] == CIVILIAN)
