ToME: the Tales of Maj'Eyal

I'm messing with modifying the Ashes DLC content with another addon, and I've run into an issue.

I understand that I have to make sure my addon loads after Ashes to make its changes appear, and that appears to be happening in te4_log.txt. I'm trying to superload some talent changes ... but TOME doesn't seem to think the talents I'm modifying have been defined.

Lua Error: ...gmod/superload//data/talents/corruptions/corruptions.lua:23: attempt to index field 'T_SHARE_THE_PAIN' (a nil value)
At [C]:-1 __newindex

I've superloaded talent changes before, and I used the same method here - referencing Talents.talents_def, so I'm a little stumped. I see no indication that the new talents in Ashes aren't loaded to the same table, nor that loadDefinition in ActorTalents has changed how it generates the table id for each talent.

Anyone else tried messing with Ashes' new talents?

I do not think it's a good way to modify addon-based contents with Superload. Here's my suggestion. (Assuming your addon is named as tome-myaddon)

(1)Make a folder as tome-myaddon/data

(2)Copy the file currently you have in your superload folder to this folder. And remove the first and the very last line. They shall be "local _M = loadPrevious " and "return _M". Let's assume that this file is named as "newtalent.lua".

(3)Make a folder as tome-myaddon/hooks and put a new file called "load.lua" in it.

(4)In load.lua, put the following things in:
local ActorTalents = require "engine.interface.ActorTalents"
class:bindHook("ToME:load", function(self, data)
ActorTalents:loadDefinition("/data-myaddon/newtalent.lua")
end)

The highlighted part shall be changed according to the real name of the folder and file. Sorry for my poor English ^_^

Your English is very good. No need to apologize.

Okay, so I set up the hook (note, set hooks to true in init.lua or you'll spend an hour staring dumbly at your code wondering why your addon won't admit hooks exist) and ... now, instead of not seeing the Ashes-specific entries in Talents, my attempted changes can't see Talents at all.
Now, what I'm attempting to do is directly change parameters of the relevant talents by referencing Talents, eg:
This works for superloading on core game stuff. Should I be trying something completely different when trying to use a hook into another addon's content?

Better post the code, the error doesn't match with what you think is wrong.

Okay, cleaned that up, posted something from a failed attempt.

The problematic piece of code looks like this.
I tried a more normal hook (loading a race definition) in this same function, and if I don't try the Talents call, the race definition works.

"Talents" onl works in files you loadList like said above. You otherwise have to do explicit somewhere in front of your line.

Without the complete code, and assuming the previous error is the one you are getting, all I can think of is that you need self and data as function arguments.
But really, three lines of code in isolation makes it really hard to debug.

function hookLoad(self, data)

Okay, yeah, I wasn't very clear. 0player's suggestion fixed things, so I'll try to lay out what I was trying to do, and what eventually worked, in case this is useful for anyone else.

I wanted to modify individual parameters of a talent. With core talents, this is pretty straightforward - just superload something like:
where T_CHANT_OF_FORTRESS is the talents_def id of the talent I want to mess with (if the talent doesn't specify a short name, just use the normal name in all caps with spaces and ' replaced with _ - then tack T_ on the front)

and sustain_positive is the parameter I wanted to change.

The talent I wanted to modify was in the new Ashes DLC. Trying to superload changes onto something introduced by another addon fails, though. Thanks to everyone's patient explanations, this is what eventually worked:

1. I followed wuxiangjinxing's suggestion - take "local _M = loadPrevious " out of my superload file, move the superload file (renamed to mytalentchanges.lua for this example) to tome-myaddon/data, add load.lua to tome-myaddon/hooks, add the following to load.lua:

   Code: Select all

   local class = require "engine.class"
   local DM = require("data-myaddon.mytalentchanges")
   
   class:bindHook("ToME:load", DM.hookLoad)

• To get mytalentchanges.lua to play nice with load.lua, I wrapped my pre-existing code in the function I told load.lua to call, then add 0player's code so trying to directly reference Talents actually works:

  Code: Select all

  function hookLoad()
  local Talents = require "engine.interface.ActorTalents"
  Talents.talents_def.T_BLEAK_OUTCOME.sustain_vim = 10
  -- etc, etc
  end
  

And tada, game loads and changes show up. Thankyou to everyone for explaining this in words small enough for me to understand.
