i read the tutorials
THis
and i cant get this function to work
. this function is to check how many cars the player have.

pawn Код:

GetPlayerVehicles(playerid)
{
    new playername[24];
    GetPlayerName(playerid, playername, sizeof(playername));
    new count;
    for(new i = 0; i < MAX_VEHICLES; i++) // For every vehicles till the maximum amount
    {
        if((vCreated[i] == true) && strcmp(VehicleInfo[i][vOwner],playername == 0))
        {
            count++;
        }
    }
    return count;
}

enum where vOwner is defined

pawn Код:

enum vInfo
{
    vID, // The vehicle id used on the SA-MP to represent the vehicle.
    vModel, // The vehicle model of the vehicle.
    Float:xspawn,
    Float:yspawn,
    Float:zspawn,
    Float:anglespawn, // The array which contains position and the rotation of the vehicle in 4 cells. So, basically {X = 0, Y = 1, Z = 2, R = 3}
    vColor1, // The primary color of the vehicle.
    vColor2, // The secondary color of the vehicle.
    vOwner[MAX_PLAYER_NAME],
    bombed, // The vehicle's owner name. Remember string is a group of literal characters and the cells you provide should be the maximum length for that string.
    bool:vLocked // Bool representing if the vehicle is locked or not. (0 = False, 1 = True)
}
new VehicleInfo[MAX_VEHICLES][vInfo];

the error:

pawn Код:

E:\samp03x_svr_R2_win32\gamemodes\Untitled.pwn(4636) : error 033: array must be indexed (variable "playername")

You first need to close with ")" so strcmp will return a value and then compare if it's equal to 0.

pawn Код:

strcmp(VehicleInfo[i][vOwner],playername) == 0

Note that if VehicleInfo[i][vOwner] is null/empty, it will return false. You can use isnull macro and check if it's not null and then compare to the player's name.

You don't need an array so you know if a vehicle is created or not. If the vehicle doesn't exist, GetVehicleModel returns 0 and there's a native as well which called IsValidVehicle (not defined so you should add it yourself).

Thanks

i added vCreated[i] == true to check if vehicle is created

[superrobot48]

And Why doesnt this work ?

pawn Код:

if(newstate == PLAYER_STATE_DRIVER)
    {
        if((vCreated[vehicleid] == true) && strcmp(VehicleInfo[vehicleid][vOwner],PlayerName(playerid)) == 0)
        {
            SendClientMessage(playerid,COLOR_GREEN,"Welcome to your purchased vehicle");
            return 1;
        }
    }

i added this on OnPlayerStateChange
Please help
and when i removed (vCreated[vehicleid] == true)
it showed the message while entering any car
thanks

[Konstantinos]

OnPlayerStateChange is called with newstate as driver so the vehicle exist.

pawn Код:

public OnPlayerStateChange(playerid, newstate, oldstate)
{
    if (newstate == PLAYER_STATE_DRIVER)
    {
        new
            vehicleid = GetPlayerVehicleID(playerid);
        
        if (!isnull(VehicleInfo[vehicleid][vOwner]) && !strcmp(VehicleInfo[vehicleid][vOwner], PlayerName(playerid)))
        {
            SendClientMessage(playerid,COLOR_GREEN,"Welcome to your purchased vehicle");
        }
    }
    return 1;
}

pawn Код:

#if !defined isnull
    #define isnull(%1) \
                ((!(%1[0])) || (((%1[0]) == '\1') && (!(%1[1]))))
#endif

Not Working it is not showing anything

[Konstantinos]

If it doesn't show the message, then either VehicleInfo[vehicleid][vOwner] is null or it doesn't match with the player's name.

Debug it and go test it in-game. Post what it printed to the console/server log.

pawn Код:

printf("vOwner: \"%s\" & PlayerName: \"%s\"", VehicleInfo[vehicleid][vOwner], PlayerName(playerid));
if (!isnull(VehicleInfo[vehicleid][vOwner]) && !strcmp(VehicleInfo[vehicleid][vOwner], PlayerName(playerid)))
{
    SendClientMessage(playerid,COLOR_GREEN,"Welcome to your purchased vehicle");
}

[superrobot48]

debugged. vowner is null
[17:22:09] vOwner: "" & PlayerName: "superrobot48"

[Konstantinos]

How do you assign the owner's name to vOwner for each vehicleid?

[superrobot48]

pawn Код:

format(VehicleInfo[vehicleid][vOwner], MAX_PLAYER_NAME, vehicleOwner);

And the other code works
it checks how many cars i have
