Post Accessing an actor's inventory
How do I do it?

I want to know which items the actor has inside it's inventory, and using actor:Inventory() isn't enough.

What does

local myInv = actor:Inventory() return?

Code:
      self.Bought = self:Inventory()
      if self.Bought ~= nil then
         if self.Bought.ClassName == "AHuman" or self.Bought.ClassName == "ACrab" then
            self.Actor = self.Bought


This is a part of a script in which the function is used succesfully, it's used to spawn an actor which is inside a craft out of it.

I think it returns the next item on the inventory, since if I buy many actors it only considers the first one.

Is there any reason why you can't use HasObject / HasObjectInGroup ?

Because I don't want to know if they have a specific item, I just want to know if they have any and which are them.

Well, "if they have any" can be found by using IsInventoryEmpty().

If not, hmm.

There's clearly a table (with sub-tables, presumably, for each item in the inventory) involved there, but it doesn't look like it's exposed to Lua.

So that leaves brute force. If you use HasObjectInGroup and develop some smart group categories, you could do it pretty easily.

Actually, I'm trying to get some variables of whichever items they are holding, like mass and gold value. Specially gold value.

I can't think of any way to do this, I've never done much things related to inventories.

If you don't care about finding specifics, then you could just use:

Code:
   for Item in MovableMan.Items do   -- store all HeldDevices of the correct type and within a cerain range in a table
      HD = ToHeldDevice(Item)
      if HD and... <insert some logic>
end
end


That will iterate through every Item and determine whether it's in an Actor's Inventory or not. To get the Actor that holds the Item, get the Parent's ID, which should match your desired actor's ID. You can filter out ACrabs and other undesirables along the way.

Big problem with all of this, though; it's pretty darn expensive. You'll need to eliminate as much clutter as possible or run it very infrequently.

I'd just have to run it once, but, I'm way too busy to script that. I'll take a look on it when I get time.
