[ExeC]

pawn Код:

forward RandPlayer1(playerid);
public RandPlayer1(playerid)
{
  GivePlayerWeapon(GetRandomID(playerid), 16, 5);
  SetPlayerArmour(GetRandomID(playerid), 100);
  SendClientMessageToAll(COLOR_YELLOW, "[Random: A Random Player has been given ''5 Grenades'' and ''Full Armor'']");
  return 1;
}

Maybe that would work?

Because you forgot to add ";" to

pawn Код:

forward RandPlayer1(playerid);
