How to check the nearest vehicle - Mystique - 09.07.2010

Allright, so I need to check what vehicle that is the nearest to a player. I need this for my /carlock command.
I also need to know how to make that if the nearest one is more than for example 5 metres away it will just return 1;.

AW: How to check the nearest vehicle - GooMan - 09.07.2010

pawn Код:

public Naechstecar(playerid, Float:radius)
{
    new Float:SpielerX, Float:SpielerY, Float:SpielerZ, Float:CarX, Float:CarZ, Float:CarY;
    GetPlayerPos(playerid, SpielerX, SpielerY, SpielerZ);
    for(new i = 1; i < MAX_VEHICLES; i++)
    {
        GetVehiclePos(i, CarX, CarY, CarZ);
        if((floatabs(SpielerX-CarX)<radius)&&(floatabs(SpielerY-CarY)<radius)&&(floatabs(SpielerZ-CarZ)<radius))
        {
            return i;
        }
    }
    return false;
}

Thank you GooMan. Do I use it like

Код:

if(GetNearestCar(playerid, < 5 ))   ?

I changed it to GetNearestCar :P

            return i;

    return false;
}

This will actually get the first car that is in radius of 5 points from the player, not the nearest.
And use..

pawn Код:

if(IsPlayerInRangeOfPoint(playerid, radius, CarX, CarY, CarZ))

.. it's faster.
