Post subject:  OK, seriously, why doesn't this work?
A small tidbit of script I was making for a friend: (Props to TLB for the garbage dump script)

Code:
function Create(self)

   self.SharedHealthPool = self.Health;
   self.CurrentState = 1;
   self.SecondMode = nil;
   self.ThirdMode = nil;
   self.ActorsFound = 0;
   self.timer = Timer();
   self.garbTimer = Timer();



   local ActorTwo = CreateACrab("Crab");
   ActorTwo.Team = self.Team;
   ActorTwo.Pos.X = -5;
   ActorTwo.Pos.Y = -5;
   MovableMan:AddActor(ActorTwo);
   self.GetSecondActor = ActorTwo;
   local ActorThree = CreateACrab("Dreadnought");
   ActorThree.Team = self.Team;
   ActorThree.Pos.X = -5;
   ActorThree.Pos.Y = -5;
   MovableMan:AddActor(ActorThree);
   self.GetThirdActor = ActorThree;
   
   
   
end



function Update(self)

   if self.timer:IsPastSimMS(25) then

   if self.ActorsFound == 0 then
      self.SecondMode = self.GetSecondActor;
      print (("Actor Found:") .. (self.SecondMode.PresetName)) ;
      self.ThirdMode = self.GetThirdActor;
      print (("Actor Found:") .. (self.ThirdMode.PresetName)) ;
      self.ActorsFound = 1;
   end

   if self.CurrentState > 3 then
      self.CurrentState = 1
   end


   if MovableMan:IsActor(self.SecondMode) and MovableMan:IsActor(self.ThirdMode) then
      if self.CurrentState == 1 then
         self.SecondMode.Pos.X = -5;
         self.SecondMode.Pos.Y = -5;
         self.ThirdMode.Pos.X = -5;
         self.ThirdMode.Pos.Y = -5;
         self.SharedHealthPool = self.Health;
         self.SecondMode.Health = self.SharedHealthPool;
         self.ThirdMode.Health = self.SharedHealthPool;
      elseif self.CurrentState == 2 then
         self.Pos.X = -5;
         self.Pos.Y = -5;
         self.ThirdMode.Pos.X = -5;
         self.ThirdMode.Pos.Y = -5;
         self.SharedHealthPool = self.SecondMode.Health;
         self.Health = self.SharedHealthPool;
         self.ThirdMode.Health = self.SharedHealthPool;
      elseif self.CurrentState == 3 then
         self.Pos.X = -5;
         self.Pos.Y = -5;
         self.SecondMode.Pos.X = -5;
         self.SecondMode.Pos.Y = -5;
         self.SharedHealthPool = self.ThirdMode.Health
         self.Health = self.SharedHealthPool;
         self.SecondMode.Health = self.SharedHealthPool;
      end

      if self:IsPlayerControlled() and UInputMan:KeyPressed(26) then
         self.CurrentState = self.CurrentState + 1;
            if self.CurrentState == 1 then
               self.Pos = self.ThirdMode.Pos;
               self.Vel = self.ThirdMode.Vel;
            elseif self.CurrentState == 2 then
               self.SecondMode.Pos = self.Pos;
               self.SecondMode.Vel = self.Vel;
            elseif self.CurrentState == 3 then
               self.ThirdMode.Pos = self.SecondMode.Pos;
               self.ThirdMode.Vel = self.SecondMode.Vel;
            end
      



   else
      if MovableMan:IsActor(self.SecondMode) then
         self.SecondMode.ToDelete = true;
         print ("Deleted Second actor!");
      end
      if MovableMan:IsActor(self.ThirdMode) then
         self.ThirdMode.ToDelete = true;
         print ("Deleted Third actor!");
      end
      self:GibThis();
   end

   self.timer:Reset();
   end
      
    if self.garbTimer:IsPastSimMS(10000) then
            collectgarbage("collect");
            self.garbTimer:Reset();
      end
end



end



So, the purpose of the code is to allow a unit to be replace by other one in real time, cycling through a set of three. However, whenever the starting actor is spawned, it just gibs instantly. Could anyone point me the reason? 'Cause I checked the code several times and still haven't found anything that could be causing this.

Just curious but what kind of actors are you using?
I had a problem like that (likely not the same problem at all) when I made my sandbags using a door actor. I didn't know that I needed a attachment.

Anyway I do hope someone who knows lua can help you find the answer.

Post subject:  Re: OK, seriously, why doesn't this work?
um

it might have to do with the fact that you're positioning and spawning two actors at the same point as the first unit at the instant of creation

or the fact that you've got a GibThis line without any checks on it in an else statement

Eh, no? The first unit stays in place, the others are placed in (-5,-5), outside the map, what turns collisions off for them. I guess.

Hrmm. That might be the problem. I thought that the 'if' check was enough to prevent it from gibbing, but it might be running into some kinda snag. Gonna add some more ifs. :P



EDIT: Oh, and it's just an AHuman and two crabs. No doors this time.

Post subject:  Re: OK, seriously, why doesn't this work?
oh wait no I see the problem

you don't have enough ends.

if self:IsPlayerControlled() and UInputMan:KeyPressed(26) then

else

self:GibThis()

that's how your code reads, because you aren't closing the first statement.

Which means that, unless you're controlling the actor AND holding Z, it's immediately going to gib itself.

Post subject:  Re: OK, seriously, why doesn't this work?
Oh dang, how did I miss that?
At any rate, it's fixed now, thanks.

And since I'm already here, does anyone know of a way to force the player to switch control to a specific actor?





(On an unrelated sidenote, did anyone else notice that trying to position an actor above the Y-limit of the map causes it to spin out of control and gib after a few seconds?)

Post subject:  Re: OK, seriously, why doesn't this work?
Code:
ActivityMan:GetActivity():SwitchToActor(<target actor> , <player number> , <target actor's team>);

That will switch control of the desired player.

To get the player number from a spefic actor that is controlled:
Code:
actor:GetController().Player

Be sure to check if it's controlled before you try to get its player number.

Why, thank ya, mister. Works like a charm. (Well, an unstable, buggy, self-destructing one, but a charm anyways.)


EDIT: OK, seriously, now this is **** ridiculous. I feel I'm doing something terribly wrong here, or the game engine hates me to death. Uploading the mod so that you can take a look, and hopefully, tell what is wrong with it.

Try setting them to GetsHitByMOs = 0 when the actor isn't being used.

Post subject:  Re: OK, seriously, why doesn't this work?
I reckon that would help, but it still doesn't solve the "mirror image" thing that appears when the units are positioned.

Also, I think I should have put some instructions: just press Z to switch actors.

That do you mean by the "mirror image" thing?

Post subject:  Re: OK, seriously, why doesn't this work?
Well, I guess you'll notice that the two unselected units continually shift through two changing positions near the top of the map, essentially being in two places at the same time. No idea on what causes that. Also, if you change units three times, the third one will fall at incredibly high speed and splatter right into the ground.

Post subject:  Re: OK, seriously, why doesn't this work?
That explains alot. Make sure you set the stored actors' velocity to Vector(0,0) every frame, or else gravity will hyper-accelerate them.

Well, now it works like a charm. Actually, it works so well that I'm even astonished. Thank y'all, guys. :grin:
