EDIT: For future visitors stumbling upon this:
The issue with ID = 255 is the "GetsHitByMOs = 0" property on the Weapon!

--------
I first add a fist item to my actor upon spawning them
Code:
   self.actor = ToActor(self)
   if not (self.actor:HasObject("Fist")) then
      local newFist = CreateHDFirearm("Fist", "The5");
      self.actor:AddInventoryItem(newFist);
   end


And then later I try to access the weapons ID:
Code:
function The5Lib.GetWeaponHeldByID(obj)
   local MO = ToMovableObject(obj) --even tried casting to MO to make sure I get the ID
   if (MO.RootID == MO.ID or MO.RootID == 255) then return -1
   else return MO.RootID
   end
end


Both ID and RootID return 255.

Been 6 years since I last modded CC, so bare with me here ;)

Is the HDFirearm GetsHitsByMOs = 1? It has to be in order to be read.

Ah! Nope, GetsHitByMOs = 0.
I don't want the actors "fist" weapon to be hit-able.

Thanks for clearing that up so swiftly!

Is there any documentation meanwhile that would explain these tricky bits?
I am aware of the generated lua doc on the wiki.

The wiki pages + the miscellaneous forum posts are the only documentation I'm afraid.

An easy & practical workaround would be to have the HDFirearm fist itself be set to Scale = 0, that way the hitbox would be non-existent.

If you still want to include a visual element, you can use an Attachable that's GetsHitByMOs = 0 since it will rotate, however not shrink along with the parent.

Thanks for he heads up!

I wonder if the Attachable/Device itself will not have an ID created due to GetsHitByMOs=0
or if the ID just can't be accessed via the exposed property, for some reason.


BTW:
Can I set a scale in the .ini on the HDFirearm?
Or how would I generally go about prevent any interaction in there, without messing with GetsHitByMOs.

Also, can I dynamically scale objects in luascript? I wanted to do a weapon back the day, but I think it crashed CC.

The Scale value can only be applied in .lua, I'm afraid.

Yeah, the only thing it's good for is Scale = 0, as it doesn't seem to ♥♥♥♥ with the engine too much. Generally the game doesn't like the value being altered.

See if I can make it without crashing CC by now.
