Attempt to index field "trader" (a nil value) abigailbrain.lua

[DSTMCreator]

(Sorry for my bad english)

Hello everyone. I need help. I have my own mod. It adds new character based on wendy and another one based on abigail. when I try to summon ghost I get this error message:

string "scripts/brains/abigailbrain.lua":45: attempt to index field "trader" (a nil value)

It says trader is a nil value.

Here is code from abigailbrain.lua (45th string):

local function GetTraderFn(inst)
	local leader = inst.components.follower ~= nil and inst.components.follower.leader
	if leader ~= nil then
		return inst.components.trader:IsTryingToTradeWithMe(leader) and leader or nil -- HERE inst.components.trader is nil
	end
end

And code from abigail.lua:

-- ...
-- 375th string
local function fn()
    inst = CreateEntity()

    inst.entity:AddTransform()
    inst.entity:AddAnimState()
    inst.entity:AddSoundEmitter()
    inst.entity:AddLight()
    inst.entity:AddNetwork()

    inst.AnimState:SetBank("ghost")
    inst.AnimState:SetBuild("ghost_abigail_build")
    inst.AnimState:PlayAnimation("idle", true)
    inst.AnimState:SetBloomEffectHandle("shaders/anim_bloom_ghost.ksh")

    inst:AddTag("character")
    inst:AddTag("scarytoprey")
    inst:AddTag("girl")
    inst:AddTag("ghost")
    inst:AddTag("noauradamage")
    inst:AddTag("notraptrigger")
    inst:AddTag("abigail")
    inst:AddTag("NOBLOCK")

    inst:AddTag("trader")
	inst:AddTag("ghostlyelixirable")
-- ...
-- 359th string
	inst:AddComponent("trader")
	inst.components.trader:SetAbleToAcceptTest(AbleToAcceptTest)

It happened only after last update (wendy update).

Before this update everything worked fine.

what am I doing wrong? why trader is nil?

Trader is nil because the brain is expecting to have in the entity's prefab: inst:AddComponent("trader")

This happened in Wendy update since the flower rework lets you give the flower and elixirs to Abigail directly..

thank you but...

error message confused me. as a result, the error file was not even mentioned in the error message! but anyway I fixed error.

and got another...

../mods/newdust/modmain.lua:117 attempt to index field "inst" (a nil value)
LUA ERROR stack traceback:
	../mods/newdust/modmain.lua:117 in (method) Visit (Lua) <114-120>

And code from modmain:

AddBrainPostInit("abigailbrain", function(self)
	local _atfn = self.inst.components.aura.auratestfn
	self.inst.components.aura.auratestfn = function(inst, target)
		if inst.cowardmode then
			return false
		end
		return _atfn(inst, target)
	end
	local _caav = self.bt.root.children[1].Visit
	self.bt.root.children[1].Visit = function(self)
		_caav(self)
		if self.status == GLOBAL.RUNNING then
			local leader = self.inst.components.follower.leader
			if leader and not self.inst:IsNear(leader, 15) then
				self.inst.cowardmode = true
				self.status = GLOBAL.FAILED
				self.inst.components.combat:GiveUp()
				self.inst.components.locomotor:Stop()
				return
			else
				self.inst.cowardmode = nil
			end
		end
	end
	local _offn = self.bt.root.children[2].Visit
	self.bt.root.children[2].Visit = function(self)
		_offn(self)
		if self.status == GLOBAL.SUCCESS then
			self.inst.cowardmode = nil -- <--- HERE
			return
		end
	end
end)

inst is nil...

You're redefining what 'self' is by function scope.
