Function don't work. - budelis - 31.10.2012

Hi,

i use function:

Код:

new Float:DISTANCE;
    GetPlayerPos(playerid, SavePos[ playerid ][ 0 ], SavePos[ playerid ][ 1 ], SavePos[ playerid ][ 2 ]);

    for(ivh= 1; ivh < MAX_VEHICLES; ivh ++)
    {
        DISTANCE = GetVehicleDistanceFromPoint(ivh, SavePos[ playerid ][ 0 ], SavePos[ playerid ][ 1 ], SavePos[ playerid ][ 2 ]);
}

But when i print distance i get 0.000000.

are the savepos variables Floats?

Re: Function don't work. - budelis - 31.10.2012

Yes. I just want to get closest car, but server always found, but it's realy not.

Код:

stock GetClosestVehicle(playerid, Float:range)
{
    SAVEVEHICLEID[ playerid ] = 0;
	new Float:DISTANCE;
    GetPlayerPos(playerid, SavePos[ playerid ][ 0 ], SavePos[ playerid ][ 1 ], SavePos[ playerid ][ 2 ]);

    for(new ivh = 1; ivh < MAX_VEHICLES; ivh ++)
    {
        DISTANCE = GetVehicleDistanceFromPoint(CikleSave[ playerid ], SavePos[ playerid ][ 0 ], SavePos[ playerid ][ 1 ], SavePos[ playerid ][ 2 ]);
        
        if(DISTANCE <= range )
        {
            SAVEVEHICLEID[ playerid ] = ivh;
            break;
        }
    }
}

i try to check if

Код:

if( SAVEVEHICLEID[ playerid ] == 0 )

This will be, if there is no near vehicle in 7 metres, but this never happen there is always car. Then i try to print and i get distance 0, then this check will work:

Код:

if(DISTANCE <= range )
      {

And this happen for vehicleid 1.

I use this

pawn Код:

GetDistanceToCar(playerid,carid) //By Darkrealm (Edited by Sacky)
{
    new Float:dis;
    new Float:x1,Float:y1,Float:z1,Float:x2,Float:y2,Float:z2;
    if (!IsPlayerConnected(playerid))   return -1;
    GetPlayerPos(playerid,x1,y1,z1);
    GetVehiclePos(carid,x2,y2,z2);
    dis = floatsqroot(floatpower(floatabs(floatsub(x2,x1)),2)+floatpower(floatabs(floatsub(y2,y1)),2)+floatpower(floatabs(floatsub(z2,z1)),2));
    return floatround(dis);
}

pawn Код:

stock GetClosestCar(playerid) //By Darkrealm
{
    if (!IsPlayerConnected(playerid))  return -1;
    new Float:prevdist = 100000.000;
    new prevcar;
    for (new carid = 0; carid < MAX_VEHICLES; carid++)
    {
        new Float:dist = GetDistanceToCar(playerid,carid);
        if ((dist < prevdist))
        {
             prevdist = dist;
             prevcar = carid;
        }
    }
    return prevcar;
}

Код:

CMD:check(playerid,params[])
{
	GetClosestVehicle(playerid, 7.0)

	if( SAVEVEHICLEID[ playerid ] == 0 )
	{
	    SendClientMessage( playerid, COLOR_RED,"* No vehicle exist.");
	    return 1;
	}
	return 1;
}

I never get this message "No vehicle exist.". But it's really not car near my.

try changing the for loop in our stock to

pawn Код:

for(new ivh = 0; ivh < MAX_VEHICLES; ivh ++)
