Using arrays? - arjanforgames - 19.08.2013

I've got this:

pawn Код:

new CGLSVehicles[23];

Then I created my vehicles like this:"

pawn Код:

CGLSVehicles[1] = AddStaticVehicleEx(472,-2954.7998047,491.1992188,0.0000000,63.9953613,6,-1,15); //Coastguard

    CGLSVehicles[20] = AddStaticVehicleEx(597,-2982.1999512,458.3999939,4.6999998,337.9998779,7,1,15); //Police Car (SFPD)

Now how can I use all of these vehicles at once?

pawn Код:

public OnPlayerEnterVehicle(playerid, vehicleid, ispassenger)
{
    if(GetPlayerVehicleID(playerid) == CGLSVehicles[]) // LINE 656
    {
    
    }
    return 1;
}

I tried this but I get this error:

pawn Код:

(656) : error 029: invalid expression, assumed zero
Pawn compiler 3.2.3664          Copyright (c) 1997-2006, ITB CompuPhase


1 Error.

Re: Using arrays? - RajatPawar - 19.08.2013

You need to ****** how to traverse arrays! For this, you need the "for loop"

pawn Код:

for(new counter = 0; counter < sizeof(CGLSVehicles); counter++)
{
      if(GetPlayerVehicleID(playerid) == CGLSVehicles[counter])
      {
              // code
      }
}

counter is a variable that gets incremented at each iteration until it reaches the maximum value of the array limit (here, 22) and it will stop (THAT ITERATION won't get executed.) Make sure you use 'break;' after your statement to get OUT of the loop. If you want to skip a particular run (iteration) use continue.

pawn Код:

public OnPlayerEnterVehicle(playerid, vehicleid, ispassenger)
{
    for(new i; i < sizeof(CGLSVehicles); i++)
    {
        if(GetPlayerVehicleID(playerid) == CGLSVehicles[i]) // LINE 656
        {
            //Do stuff, they're in one of your vehicle!
            break; //Stop the loop, we don't need it anymore.
        }
    }
    return 1;
}

Well that will work but you don't want to keep calling the same function every iteration it should actually look like this.

pawn Код:

public OnPlayerEnterVehicle(playerid, vehicleid, ispassenger)
{
    vid = GetPlayerVehicleID(playerid);
    for(new i; i < sizeof(CGLSVehicles); i++)
    {
        if(vid == CGLSVehicles[i]) // LINE 656
        {
            //Do stuff, they're in one of your vehicle!
            break; //Stop the loop, we don't need it anymore.
        }
    }
    return 1;
}

I'd also make a dynamic car loader instead of sequentially incrementing the array during vehicle creation.

    new veh = GetPlayerVehicleID(playerid);
    for(new i; i < sizeof(CGLSVehicles); i++)
    {

        {
            //Do stuff, they're in one of your vehicle!
            break; //Stop the loop, we don't need it anymore.
        }
    }
    return 1;
}

By the way, it's:

pawn Код:

public OnPlayerEnterVehicle(playerid, vehicleid, ispassenger)
{
    for(new i; i < sizeof(CGLSVehicles); i++)
    {
        if(vehicleid == CGLSVehicles[i]) // LINE 656
        {
            //Do stuff, they're in one of your vehicle!
            break; //Stop the loop, we don't need it anymore.
        }
    }
    return 1;
}

And, there is no difference as this function will be called along side again and again either if it's out the loop.

There is not need to get the player vehicle ID as the callback already has it ..

There is a difference because variables are faster than functions. But in this case you already have the function parameter so you might as well use it.

Re: Using arrays? - Jefff - 19.08.2013

ONEV is called when player press enter button so GetPlayerVehicleID didnt works? xd

If you are using static vehicles, simply way

pawn Код:

new CGLSVehicles[23]; // is from 0 to 22

public OnPlayerEnterVehicle(playerid, vehicleid, ispassenger)
{
    if(CGLSVehicles[0] <= vehicleid <= CGLSVehicles[22])
    {
        // do something
    }
    return 1;
}

if not, use Cypress code

Re: Using arrays? - Ash. - 21.08.2013

Apologies, use 'vehicleid' as per my code snippet instead of GetPlayerVehicleID. I'm too used to working with OnPlayerStateChange!
