Check For Hostiles Unit(s) Behind Player

[Apexx 60]

Hi, I am having problems understanding IsBehind. I would like to check if there are any mobs behind me. I am trying to add a backpedal feature to my fight class, but I don't think I am getting it correct. Here's what I tried:

var EnemiesBehind = new List<WoWUnit>();
EnemiesBehind.AddRange(ObjectManager.GetWoWUnitHostile().Where(
    u => u.IsValid && !u.InCombat && u.IsAlive && u.IsBehind(Player.Position, 180.0f) &&
    u.GetDistance <= Settings.BackpedalScanRange).OrderBy(
    o => ObjectManager.Me.Position.DistanceTo(o.Position)));

if (EnemiesBehind != null && EnemiesBehind.Count > 0)
{
    MyFunctions.LogDebug("Enemy, (" + EnemiesBehind.FirstOrDefault().Level + ")" + EnemiesBehind.FirstOrDefault().Name +
        " found behind you, skipping backpedal!");
    Var.SetVar("CanBack", false);
  	return;
}

Any help is much appreciated! Thank you!

I may have something here if anyone is interested. It still needs more testing though.

Code:

private void FightEventsOnFightStart(WoWUnit wowUnit, CancelEventArgs cancelable)

    try
    {
        if (Settings.Backpedal)
            Var.SetVar("CanBack", true);
    }
    catch (Exception ex)
    {
        MyFunctions.LogWrite("FightEventsOnFightStart() Exception:" + Environment.NewLine + ex.ToString(), true);
    }
}

private async void FightEventsOnFightLoop(WoWUnit wowUnit, CancelEventArgs cancelable)

    Random _rand = new Random();
    bool _playerAggro = false;
    bool _playerStuck = false;

        (!Player.IsPartyMember || ObjectManager.Me.IsInGroup) &&    // Let's not backpedal in groups!
        Var.Exist("CanBack") &&                                     // Make sure our Variable exists
        Var.GetVar<bool>("CanBack") &&                              // Make sure the Variable is TRUE

Hello, you need to use IsBehind like that:

u.IsBehind(ObjectManager.Me.Position, ObjectManager.Me.Rotation);
ObjectManager.Me.IsBehind(u.Position, u.Rotation);

you can also use:

MovementManager.IsFacing(Me.Position, Me.Rotation, u.Position, 2.20f)

Hey @Droidz thank you again!
