PHP код:

public UpdatePlayerVelocimetro(playerid) 
{
    new playervehicle = GetPlayerVehicleID(playerid)
    if (playervehicle != INVALID_VEHICLE_ID) 
{
        new string_velo[15];
        format(string_velo, sizeof (string_velo), "%02d km/h", GetVehicleSpeed(playervehicle));
        PlayerTextDrawSetString(playerid, textPlayerVelocimetro[1][playerid], string_velo);
        format(string_velo, sizeof (string_velo), "%.0f%", GetVehicleHealthEx(playervehicle));
        PlayerTextDrawSetString(playerid, textPlayerVelocimetro[3][playerid], string_velo);
        
        format(string_velo, sizeof (string_velo), "%02d Litros", Gas[playervehicle]);
        PlayerTextDrawSetString(playerid, textPlayerVelocimetro[2][playerid], string_velo);
    }
    return 1;
} 


penso que assim ta corrigido,
define a public,

PHP код:

forward UpdatePlayerVelocimetro(playerid);
