Get nearest vehicle while in vehicle - Antenastyle - 06.05.2017

How can I get the closest vehicle while I'm in any vehicle?

Currently, I have this function, but it only works while on foot.

Код:
stock GetClosestVehicle(playerid, Float:range)
{
	new Float: x, Float: y, Float: z;
	new Float: dist, closeveh;
	for(new i = 1; i < MAX_VEHICLES; i++)
	{
		if(GetVehiclePos(i, x, y, z))
		{
			dist = GetPlayerDistanceFromPoint(playerid, x, y, z);
			if(dist < range)
			{
				//closedist = dist;
				closeveh = i;
			}
		}
	}
	return closeveh;
}

I don't understand why you're assigning a vehicle id into a float variable.

PHP код:
stock GetClosestVehicle(playerid, Float:range)
{
    new Float: x, Float: y, Float: z;
    new Float: closedist = range;
    new closeveh;
    for(new i = 1; i < MAX_VEHICLES; i++)
    {
        if(GetVehiclePos(i, x, y, z))
        {
            dist = GetPlayerDistanceFromPoint(playerid, x, y, z);
            if(dist < closedist)
            {
                closedist = dist;
                closeveh = i;
            }
        }
    }
    return closeveh;
} 
If you want to not count the vehicle you are currently in. Then use this.

PHP код:
stock GetClosestVehicle(playerid, Float:range)
{
    new Float: x, Float: y, Float: z;
    new Float: closedist = range;
    new closeveh;
    for(new i = 1; i < MAX_VEHICLES; i++)
    {
        if(GetVehiclePos(i, x, y, z))
        {
            if (IsPlayerInVehicle(playerid, i)) continue;
            dist = GetPlayerDistanceFromPoint(playerid, x, y, z);
            if(dist < closedist)
            {
                closedist = dist;
                closeveh = i;
            }
        }
    }
    return closeveh;
}

Tags are per-definition only, which are separated by a comma.

As an example
PHP код:
new Float: x, Float: y, Float: z; 
You have to define the tag every time after the comma.

Here, closeveh is an integer value, not a float value.
PHP код:
new Float: dist, closeveh;

This could be optimized like this, you don't have to call IsPlayerInVehicle each time in the loop.

PHP код:
stock GetClosestVehicle(playerid, Float:range) 
{ 
    new Float: x, Float: y, Float: z; 
    new Float: closedist = range; 
    new closeveh; 
    new playerveh;
    playerveh = GetPlayerVehicleID(playerid);
    for(new i = 1; i < MAX_VEHICLES; i++) 
    {
         if(playerveh == i) continue; 
        if(GetVehiclePos(i, x, y, z)) 
        {  
            dist = GetPlayerDistanceFromPoint(playerid, x, y, z); 
            if(dist < closedist) 
            { 
                closedist = dist; 
                closeveh = i; 
            } 
        } 
    } 
    return closeveh; 
}

Optimized this code as much it could be, made checks to avoid invalid vehicle in the loop and so on.

PHP код:
stock GetClosestVehicle(playerid, Float: range)
{
    new Float: PosX, Float: PosY, Float: PosZ, Float: CloseDist = range, Float: Dist, FetchVeh, PlayerVeh;
    PlayerVeh = GetPlayerVehicleID(playerid);
    for(new i = GetVehiclePoolSize(); i != 0; i--)
    {
        if(!IsValidVehicle(i)) continue;
        if(i == PlayerVeh) continue;
        GetVehiclePos(i, PosX, PosY, PosZ);
        Dist = GetPlayerDistanceFromPoint(playerid, PosX, PosY, PosZ);
        
        if(Dis <= CloseDist)
        {
            FetchVeh = i;
            CloseDist = Dist;
        }
    }
    return FetchVeh;
}
