I am creating a vehicle thing. I need to check to see if the players vehicle that they are in is on an array. please help me

this is what i have so far.

array:

Code:

new RandomRegularVehicle[][3] =
{
    // Positions, (model, low price, high price)
    {400, 20000, 21000},
    {401, 18000, 19000},
    {404, 18000, 19000},

Check to see if its on there:

Code:

if(CarInfo[idx][cModel] != RandomRegularVehicle[][0]) return SendClientMessage(playerid, COLOR_RED, "You cannot sell this type of vehicle here");

please help me

Do that in a for loop for the max vehicle count.

Im confused, could you show me what your talking about?

Re: Check to see if something is in an array - Madd92 - 14.05.2014

pawn Code:

for (new i = 0; i < sizeof(RandomRegularVehicle); i++)
        if(CarInfo[idx][cModel] != RandomRegularVehicle[i][0]) return SendClientMessage(playerid, COLOR_RED, "You cannot sell this type of vehicle here");

Re: Check to see if something is in an array - Vince - 15.05.2014

That is incorrect. If the first vehicle doesn't match, it will return the error without even checking the rest of the array. Never return inside a loop unless you explicitly want to break it.

Sorry, you are correct of course. You'd have to break the loop when there is a match. Then after the loop you'd have to check if the index is the size of the array. If not, there was a match so you can sell it, if it is the maximum, you can't.

pawn Code:

new i;
for (i = 0; i < sizeof(RandomRegularVehicle); i++)
    if(CarInfo[idx][cModel] == RandomRegularVehicle[i][0]) break;
if (i == sizeof(RandomRegularVehicle))
    return SendClientMessage(playerid, COLOR_RED, "You cannot sell this type of vehicle here");

That didn't work either.

bool:IncorrectModel(modelid)
{

    for(new i=0; i != sizeof(RandomRegularVehicle); i++)
        if(RandomRegularVehicle[i][0] == modelid)
            return true;

    return false;
}

if(!IncorrectModel(CarInfo[idx][cModel])) return SendClientMessage(playerid, COLOR_RED, "You cannot sell this type of vehicle here");
