Link a carkey to a car - AIped - 17.01.2016

Okay i was just wondering if i could link a key to a vehicle just by using the vehicles id or should i make a new value
for that.

So basicly ..would this work ?

pawn Code:

new Key[MAX_VEHICLES];

(somewhere in the script)

Key[myvehicle] = 23;//  (23 is just an example and in this case should also be the 23st vehicle id in the script)

if(Key[vehicleid] == vehicleid)
{
 //this should be your car
}
else
{
 //the vehicle id and the Key id wont match so its not your car.
}

When most servers do it, they have a key variable on the player, that matches the car id.

Thanks yea i actually meant Keys[MAX_PLAYERS]; instead of MAX_VEHICLES but anyways you cleared my doubt.

This is for someone, so I won't share the code. Well, you can just say that I came to show it off,

P.S. It's not made how you mentioned you are going to make it as you can have multiple vehicle keys and you can also duplicate vehicle keys at a business. You can also duplicate keys to businesses and businesses have keys too, well of course.

Anyway, in all means, there are different ways of accomplishing this. And good luck!

i see..thats just different slots in a players variable so you can have more keys than one right ?
I dont think i will use that but yea its a good idea.

Code:

new pVehicle[MAX_PLAYERS];

pVehicle[playerid] = CreateCar(...);

if(pVehicle[playerid] != GetPlayerVehicleID(playerid))
   return ... // do something here. i.g: return SendClientMessage(playerid, -1, "You do not have a key.");

/* if the script reaches this line, their pVehicle variable equals the vehicleid.
    you could turn the engine on/off now with GetVehicleParamsEx(...) and SetVehicleParamsEx(...)
*/

If you need further explaining, reply and I will answer.

Lets say you want 3 keys for each vehicle. So we declare a 2D array with the last as the keys limit.

pawn Code:

new key[MAX_VEHICLES][3];

So whenever you create a vehicle, set the array to INVALID_PLAYER_ID which means no one has the key of the specific vehicle.
So you understand we are putting player ids in "key" variable.

pawn Code:

new i = CreateVehicle(..);

key[i][0] = INVALID_PLAYER_ID;
key[i][1] = INVALID_PLAYER_ID;
key[i][2] = INVALID_PLAYER_ID;

So if suppose a user "Gammix" id is "0", "AIped" id is 1 and "Third" id is 2.
Lets give id 0 and 1 i.e. "Gammix" and "AIped" the key for vehicle id 0.

pawn Code:

key[0][0] = 0;
key[0][1] = 1;

Here is a breakdown:

Code:

key[*][**] = ***;

* - is the vehicle id for which the keys will be given.
** - is the key slot, 0 means fist key and so on.
*** - is the player's id who will be having the key.

In order to check if the player has the key of vehicleid 0:

pawn Code:

for (new i; i < 3; i++)
{
    if (key[0][i] == playerid)
    {
        // player has the key
        break;
    }
}

That's bad, there's no need for a loop. And what if I want to give 5,000 players the key to the vehicle? Then that would required an extra load on the connection of a player.

5000 players isn't possible. And if you are talking about database, SQL can handle this in a few second(s).

And i guess how would you search key holders of a specific vehicle from a 5000 player database, to make it faster than a vehicle based key system?

All it will be is a Keys[CarID][MaxPlayers]

Try maybe 3-5 at first, it's not that hard. It's a 3 dimensional array or something.
