Invalid vehicle and ispassenger - Vvolk - 24.11.2012

Hello everybody. I have problem with my server. Some cheaters or buggers buging my server. In server log I have these lines:

But I don't have a lot of vehicles, It can't be such vehicleid. How to make protection against this?

Re: Invalid vehicle and ispassenger - iggy1 - 24.11.2012

It's not cheaters, your code is bugged.

You are accessing an array out off bounds.

EG:

pawn Код:

new array[5];
array[10] = 6;//array is size '5' but we are trying to access '10'

This:

Код:

Accessing element at index 11664 past array upper bound 999

Means you have an array that is size 1000, and you are accessing 11664.

No. I don't have this problem. I am not a newbie. It is something called "Server fucker". This thing sends onplayerentervehicle callback with invalid numbers. There is everything okay with my arrays.

Re: Invalid vehicle and ispassenger - iggy1 - 24.11.2012

If that's actually what it is called you should delete that ASAP.

It seems you are using the 'vehicleid' as an index to an array?

Try using the native IsValidVehicle:

pawn Код:

native IsValidVehicle(vehicleid); // It works, but it's not in the includes for some reason (https://sampwiki.blast.hk/wiki/IsValidVehicle)

public OnPlayerEnterVehicle(playerid, vehicleid)
{
    if(!IsValidVehicle(vehicleid))
    {
        // Whatever you want to do with him
        Ban(playerid);
        return 0;
    }

    // The rest of your code
    return 1;
}
