You need to check if at least 1 player in that team has score bigger than 0. If not, then team loses.

pawn Код:

new armylost=1;
for(new i; i<GetMaxPlayers(); i++)
{
    if(IsPlayerConnected(i))
    {
        if(gTeam[i]==TEAM_ARMY)
        {
            if(GetPlayerScore(i) > 0)
            {
                armylost = 0;
                break;
            }
        }
    }
}
if(armylost == 1)
{
    SendClientMessageToAll(COLOR_BLUE,"Las Venturas Army has lost the battle.");
