Post subject:  Very strange Lua error...
This Lua script I made is attached to a MOPixel and is supposed to turn the closest actor (self.parent) within the defined distance into a "phoenix," meaning the target actor respawns when it dies. However, it gives a strange error when the target actor (self.parent) dies.

Code:

Code:
function Create(self)
   self.respawned = false;
   self.gottarget = false;
   self.parent = nil;
   self.parentname = nil;
   local curdist = 10;
      for actor in MovableMan.Actors do
         local avgx = actor.Pos.X - self.Pos.X;
         local avgy = actor.Pos.Y - self.Pos.Y;
         local dist = math.sqrt(avgx ^ 2 + avgy ^ 2);
         if dist < curdist and actor.ClassName == "AHuman" then
   self.parent = actor;
   self.parent:FlashWhite(100);
   self.gottarget = true;
   end
    end
end

function Update(self)
   self.ToSettle = false;
   self.ToDelete = false;

   if MovableMan:IsActor(self.parent) then
   self.Pos = self.parent.Pos;
   self.Vel = Vector(0, 0);
   end

   if not(MovableMan:IsActor(self.parent)) and self.gottarget == false then
   self.ToSettle = true;
   self.ToDelete = true;
   self.LifeTime = 0;
   end

   if MovableMan:IsActor(self.parent) and not(self.parent:HasObject("Phoenix Respawner")) then
   self.parent:AddInventoryItem(CreateHDFirearm("Phoenix Respawner" , "CLMiniMods.rte"));
   end

   if MovableMan:IsActor(self.parent) and self.parent:IsPlayerControlled() == true then
   self.iscontrolled = true;
   end

   if MovableMan:IsActor(self.parent) and self.parent:IsPlayerControlled() == false then
   self.iscontrolled = false;
   end

   if self.gottarget == true and not(MovableMan:IsActor(self.parent)) then
   self.phoenixrespawn = CreateAHuman(self.parent);
   self.phoenixrespawn.Pos = self.Pos;
   self.phoenixrespawn.Team = self.parent.Team;
   self.phoenixrespawn:AddInventoryItem(CreateHDFirearm("Phoenix Respawner" , "CLMiniMods.rte"));
   MovableMan:AddActor(self.phoenixrespawn);
   self.parent = self.phoenixrespawn;
   self.respawned = true;
   end

   if self.respawned == true then
      if self.phoenixrespawn.iscontrolled == false then
   self.respawned = false;
   end
end

   if self.respawned == true then
      if self.phoenixrespawn.Team == 0 and self.phoenixrespawn.iscontrolled == true then
   ActivityMan:GetActivity():SwitchToActor(self.phoenixrespawn,Activity.PLAYER_1,0);
   self.respawned = false;
   end
end

   if self.respawned == true then
      if self.phoenixrespawn.Team == 1 and self.phoenixrespawn.iscontrolled == true then
   ActivityMan:GetActivity():SwitchToActor(self.phoenixrespawn,Activity.PLAYER_2,1);
   self.respawned = false;
   end
     end
end

Your problem lies in the way the Lua is parsed to be run.
Code:
if MovableMan:IsActor(self.parent) and not(self.parent:HasObject("Phoenix Respawner")) then

This line, along with a few others, are going to cause errors.
The program always checks every condition of an if statement before running the code. That means that in this case, even if self.parent no longer exists, it will try to check if it is holding the Pheonix Respawner. Move the object check to another if statement on another line. Do the same for any other if statements structured this way.

Ok, I fixed all those "if" statements, but I still get the same error.

Well your end syntax is horrible, it's possible you missed on and it's still not checking correctly.

Post subject:  Re: Very strange Lua error...
Checked all those end things, I'm pretty sure they're in the right place.

Post subject:  Re: Very strange Lua error...
I would highly suggest tabbing it properly. As is, I can't read the code well enough to diagnose the problem.

Tabbed.
