It means what it says, the variable playerid isn't initialized or defined in that callback...if you want the callback specifically for a playerid, you need to specify it in there. For example:

pawn Код:
public cannonshot(playerid)
{
      if(IsPlayerInAnyVehicle(playerid))
      SetVehicleVelocity(GetPlayerVehicleID(playerid),-4.5,0,0.0);
}


Re: Undefined symbol, playerid? wtf! - Andrus - 11.11.2010

make the forward like:
pawn Код:
forward cannonshot(playerid);
and public:
pawn Код:
public cannonshot(playerid)
, else you won't be able to use playerid symbol.
