cria uma variбvel para definir em qual checkpoint o player tem que ir ex:

pawn Code:

//topo do gm
new ChekPoint[MAX_PLAYERS];
new Conv_P_1;

//onplayerspawn
Conv_P_1 = SetPlayerCheckpoint(playerid, -78.452186,-1169.856323,2.137668, 1.0);//Conveniencia Posto 1

//onplayerconnect
CheckPoint[playerid] = 0;

//onplayerentercheckpoint
if(CheckPoint[playerid] == Conv_P_1)
{
CheckPoint[playerid] = 0;
SendClientMessage(playerid, -1, "Bem vindo a conveniencia do posto 1");
SetPlayerVirtualWorld(playerid, 10);
SetPlayerInterior(playerid, 17);
}
