[SOLVED] A tag mismatch warning that I don't understand... - Scenario - 07.08.2013

Okay, this makes absolutely no sense to me. I keep getting a tag mismatch on this line:

pawn Код:

if(vStats[vehicleID][vType] == VEHICLE_TYPE_FACTION)

"VEHICLE_TYPE_FACTION" is defined in an enum and " vType" is in a different enum but it doesn't have a specific tag or anything.

pawn Код:

enum eVehicleType
{
    VEHICLE_TYPE_ZERO_FILL, // bug prevention
    VEHICLE_TYPE_PERSONAL,
    VEHICLE_TYPE_FACTION,
    VEHICLE_TYPE_PUBLIC,
    VEHICLE_TYPE_BUSINESS,
};

However, if I use a switch, the warning goes away:

pawn Код:

switch(vStats[vehicleID][vType])
    {
        case VEHICLE_TYPE_FACTION:
        {
            //
        }
    }

It has nothing to do with the code above, because this has happened to me before with a different enum. I don't understand why it's doing this though. Isn't "VEHICLE_TYPE_FACTION" just being replaced with a number corresponding to the location in the enum?

Why would the switch work, but not the if statement?

Your vType is probably inside enum declaring strong tag (starting with big letter). Like:

pawn Код:

enum VehicleInfo {
    vType
    //(...)
}

So, do one of the following:

pawn Код:

if(eVehicleType:vStats[vehicleID][vType] == VEHICLE_TYPE_FACTION)
//or
if(vStats[vehicleID][vType] == VehicleInfo:VEHICLE_TYPE_FACTION)
//or
if(_:vStats[vehicleID][vType] == _:VEHICLE_TYPE_FACTION)

#e: and the reason why switch isn't causing tag mismatches, is because everything in there is reduced to numeric constants (_ tag), while if checks everything

Come on RealCop, this is described on the Wiki

Nope, it starts with a lowercase e.

pawn Код:

enum enumVehicleData
{
    vID,
    vType,
    vOwnerID,
    vModel,
    vSecurityLevel,
    vMod0,
    vMod1,
    vMod2,
    vMod3,
    vMod4,
    vMod5,
    vMod6,
    vMod7,
    vMod8,
    vMod9,
    vMod10,
    vMod11,
    vMod12,
    Float:vPosX,
    Float:vPosY,
    Float:vPosZ,
    Float:vAngle,
    vKeys,
    vFuel,
    vPaintjob,
    vMileage,
    
    vScriptID,
    bool:vLights,
    bool:vEngine,
    bool:vAlarm,
    bool:vLock,
    bool:vBonnet,
    bool:vBoot,
    Float:vSpeedM,
    Float:vSpeedTh,
    Float:vMaxSpeedTh,
    bool:vBroken
};

@Bakr: Is it really?

#e: Is it bad if I don't name my enums? Because, removing the "name" or the "tag" of the enum seems to remove the tag mismatch warning...

Re: A tag mismatch warning that I don't understand... - Vince - 07.08.2013

Do you actually use eVehicleType as an initializer somewhere? If not, you can just remove it. Otherwise, you should prefix vType with the eVehicleType tag.

pawn Код:

enum enumVehicleData {
    eVehicleType:vType
}

Re: A tag mismatch warning that I don't understand... - Scenario - 07.08.2013

I don't. I went ahead and removed it along with some of my other enum tags. I expected the compiler to tell me I couldn't do that but everything compiled fine and the enum numbers are still the same. I have no idea why we started tagging enums anyways.

Thanks guys- problem solved!

Note to self: I should read the Wiki better.
