Amount of items in an array. - Jimmy0wns - 18.06.2015

So, this is something I've been stuck with for quite some time.

Lets say I have 5 items of vehicle information in my array. For example:

PHP код:



{451, 3.0, 4.0, 6.0, 220.0, 10000, 40000}, 

{591, 3.0, 4.0, 6.0, 220.0, 40000, 10000}, 

{512, 3.0, 4.0, 6.0, 220.0, 30000, 60000}, 

{485, 3.0, 4.0, 6.0, 220.0, 60000, 30000}, 

{412, 3.0, 4.0, 6.0, 220.0, 90000, 90000}

How would one get the amount of items in that array? I tried using sizeof(thisarray[]); but without success, it gave me a random number.

Could this be done with foreach somehow? I've not used foreach much but im trying to figure it out using the standalone include - But i don't know how to use it that well

I've tried that, but it'll just result in a number which has been set as the max amount.

e.g: MAX_PLAYER_VEHICLES is set to 2000 and if you make a loop through that and save the result, it'll say 2000.

pawn Код:

new arr[][] =
    {
        {1, 2, 3, 4},
        {3, 4, 6, 6}
    };
    
    printf("%d %d", sizeof(arr), sizeof(arr[]));

Gave me results as 2 & 4.
Why didn't it work with yours?

Probably because I do this all in a very different way, I use enums as well but I just couldn't think of the right terms when posting this topic.

I usually make an enum like this:

PHP код:



enum _VehicleData

{

    vID,

    vOwner[128],

    vLocation[128],

    

    vModel,

    Float:vPosX,

    Float:vPosY,

    Float:vPosZ,

    Float:vPosAngle,

    vColor1,

    vColor2,

    

    vPrice,

    vDefaultPrice,

    vForSale,

    

    Text3D:vText,

    curVehID,

};

And then use this:

PHP код:



new VehicleData[MAX_VEHICLES][_VehicleData];

Whereas the items for this array get loaded with a MySQL query when the server starts.

Solved it by using this.

PHP код:



new total;

    

for(new i; i<sizeof(VehicleData); i++)

{

    if(VehicleData[i][vModel] == 0)

    {

        total = i;

        break;

    }

}

printf("%d", total);
