[Nero_3D]

Basically you check each time you send a messeage which text the script should show the player (depending which language the player has set)

pawn Код:

switch(Language[playerid])
{
    case ENGLISH: SendClientMessage(playerid, -1, "English");
    case VIETNAM: SendClientMessage(playerid, -1, "VIETNAM");
}

Either you create your own system or you use an existing one like y_languages
