More stupid questions: loading_list, and entity destruction

[ibanix]

So more of me trying to screw around with t-engine and getting lost.

Today's questions:

1) What exactly is loading_list? It seems to be able to be used to reference entities that have already been loaded from a file?

2) How do I delete an entity? In this case, I'm try to have an addon delete an ego from the list of possible egos. Is there a way I can reference a table and then remove it from the table?

Thanks!

[sound F/X: source diving] That's some magic done by Entity:loadList(). If you're in a file being loaded by Entity:loadList(), loading_list will be a reference to the list of entities being loaded.

2) How do I delete an entity? In this case, I'm try to have an addon delete an ego from the list of possible egos. Is there a way I can reference a table and then remove it from the table?

You can do this from an 'Entity:loadList' hook. In your hooks/load.lua, add something like:

Code: Select all

class:bindHook('Entity:loadList', function(self, data)
  -- data.file is the name of the file being loaded.
  if data.file == '/data/general/objects/egos/file-that-defines-the-ego-you-want-to-remove.lua' then
    -- data.res is the table into which entities are being loaded; you can manipulate
    -- it to alter or remove entities.
    for i, e in ipairs(data.res) do
      if e.name == 'the ego you want to remove' then
        table.remove(data.res, i)
        break
      end
    end
  end
end)

For comparison, I do something like this in Worms Don't Walk.
