Hi, i only ask this after thoroughly racking my brains . I want to get the closest of 3 set Vector3 locations the Player is closest to. The way i have been doing it is checking if the player is closest to 1 or 2, and then i check that result to 3, however it always returns that i'm closest to 1, no matter what.

Has anyone done anything similiar and have an easy method? Ask me if i'm not being clear enough!

Thanks.

How are you checking the distance? There's a method which takes a vector3 and gives you the travel distance

I'm using a DistanceTo() extension for vector3 (got it off of LCPDFR - the stickied thread by LMS)

Vector3.traveldistanceto()

That's one of the common ways to do it. I would test what results you get with Vector3.TravelDistance()

I've used it plenty of times and it's always been accurate for me. I had a list of spawn points that I would loop through and check their distance to the LocalPlayer

Still no go, it still is setting me closest to location 1. Here is my code - (sorted into 2 voids)

 public void firstloc()
        {
            if(Game.LocalPlayer.Character.Position.TravelDistanceTo(loc1) < Game.LocalPlayer.Character.Position.TravelDistanceTo(loc2))
            {
                Game.LogTrivial("Closer to 1");
                close21 = true;
            }

            if (Game.LocalPlayer.Character.Position.TravelDistanceTo(loc1) > Game.LocalPlayer.Character.Position.TravelDistanceTo(loc2))
            {
                Game.LogTrivial("Closer to 2");
                close22 = true;
            }
        }

        public void secondloc()
        {
            if (close21 == true)
            {
                if(Game.LocalPlayer.Character.Position.TravelDistanceTo(loc1) < Game.LocalPlayer.Character.TravelDistanceTo(loc3))
                {
                    Game.LogTrivial("Closest is 1 - setting");
                }
            }

            if (Game.LocalPlayer.Character.Position.TravelDistanceTo(loc1) > Game.LocalPlayer.Character.Position.TravelDistanceTo(loc3))
            {
                Game.LogTrivial("Closest is 3 - setting");
               
            }
        }

 

Vector3 pos1 = Game.LocalPlayer.Character.Position.GetOffsetPositionFront(50f);
Vector3 pos2 = Game.LocalPlayer.Character.Position.GetOffsetPositionFront(65f);
Vector3 pos3 = Game.LocalPlayer.Character.Position.GetOffsetPositionFront(80f);

float pos1travel = Game.LocalPlayer.Character.Position.TravelDistanceTo(pos1);
float pos2travel = Game.LocalPlayer.Character.Position.TravelDistanceTo(pos2);
float pos3travel = Game.LocalPlayer.Character.Position.TravelDistanceTo(pos3);

if(pos1travel <= pos2travel && pos1travel <= pos3travel)
{
//pos1
}
else if(pos2travel <= pos1travel && pos2travel <= pos3travel)
{
 //pos2
}
else
{
  //pos3
}

 

When you're checking the first distance, you should check it against all available distances (eg, pos2 and pos3). I'd check less than or equal to because if they're equal. Obviously if you have more than a few values to check, this solution wouldn't be the best as it would become very messy to maintain as you add values.

I highly recommend not using TravelDistance in these kind of checks as it takes into account various path nodes.

DistanceTo is highly preferred here and is standard.

Thanks @ainesophaur, that works! And @Albo1125 - i wasn't using DistanceTo as that didn't work (spawning this thread). Anyway, thanks for all your help guys!

@AnIdioticMonkey

Add your three locations to a List. Then...

Vector3 closestPoint = myLocationList.OrderBy(x => x.DistanceTo(Game.LocalPlayer.Character.Position)).FirstOrDefault();

It'll return the closest Vector3, or null if nothing was found. 

Edit: I think that's the syntax. I normally code in VB.NET, so my C# is a bit rusty if I don't have Visual Studio in front of me.

Great, thanks! That's much easier!

Vector3 is a struct, so it will return a Vector3 with X,Y and Z set to 0.0f instead of null since structs can't be null.
But for normal classes it will return null, as you said.

Right, my bad. I forgot Vector3 is a struct, so it would just return Vector3.Zero.
