I have a gun that fires MOPixels. These MOPixels have a script on them that replaces them with AEmitters after a while, and deletes the MOPixel.
However, when I fire the gun, even just a few shots, the game inevitably crashes after several seconds.
The game crashes even faster if more of them (~25) go off at around the same time. The gun works fine without the script.

Can anyone tell me what I'm doing wrong here?

Code:

function Create(self)
   self.detTimer = Timer()
end

function Update(self)
   if self.detTimer:IsPastSimMS(1750) then
      local det = CreateAEmitter("Ground Flames");
      det.Pos = self.Pos;
      det.Vel = Vector(0,0);
      det.RotAngle = 1;
      self.ToDelete = true;
      SceneMan:AddSceneObject(det);
      det = null;
   end
end

Thanks.

Turns out SceneMan:AddSceneObject has a crash bug associated with it. Does anybody know the appropriate Add command for an AEmitter through MovableMan?

MovableMan:AddParticle(YourParticlePointer)


I suppose that should work.

Brilliant, thanks! That works perfectly. Tried looking in the Luadocs on the wiki but the Add functions aren't listed there.

I didn't know addsceneobject existed at all... if it works properly when used in the right circumstances, maybe our portable bases are more of a possibility.

AddSceneObject() probably cannot be used for anything that's a Particle or Emitter. You're right, that's certainly worth experimenting with; time for some "bunker kits" if it's finally possible

MovableObject is a child of SceneObject, and so all MOs therefore follow up and are SceneObjects. Using AddSceneObject does add Particles/Emitters when run in the game, supposedly it also works with TerrainObjects as well. But I did a search for AddSceneObject and found a topic from 3 years ago mentioning that using it causes a crash, regardless of what you use it for. I think this is still the case.

Link.

Would be nice if this got a fix though. Wonder if Data knows about it.

So why did you need us to answer your question when you could have searched for it and got your answer anyway?

I had searched before, but evidently searched for the wrong thing. And then when I found out that AddSceneObject didn't work, I did a search for the Movable Object alternative (on the forums and the wiki), but again, evidently searched for the wrong thing, and couldn't find anything until Asklar suggested AddParticle. That search result linked above was when I grayed/strikethroughed my original post and appended my new question at the bottom.
