[EDITED] AnimationController object isn't a descendant of the game object?

When the player dies, the script says that the AnimController is not a child of the ViewModel. I dont know why, but here is my error, local script, and module script.

NOTE: the error occurs in the module script

ERROR HERE 17:22:06.288 - LoadAnimation requires the AnimationController object (VM_PLR.A_CT) to be a descendant of the game object

LOCAL SCRIPT HERE

local AnimService = require(game.ReplicatedStorage.ModuleScripts.LoadAnimService)

game.ReplicatedStorage.Events.BindableEvents.PlayerPressedPlay.Event:Connect(function(GunsRequested, GunsRequestedPos)
	local VM = game.ReplicatedStorage.VM_PLR:Clone()
	local fol = Instance.new("Folder", workspace.PlrVM)
	VM.Parent = fol
	local char, plr = game.Players.LocalPlayer.Character, game.Players.LocalPlayer
	fol.Name = plr.Name
	local hum = VM.A_CT
	local c = false
	for i, v in pairs(hum:GetChildren()) do
		if v:IsA("Animator") then
			c = true
			break
		end
	end
	if c == false then
		Instance.new("Animator", hum)
	end
	char.Humanoid.Died:Connect(function()
		VM.Parent = nil;
	end)
	game:GetService("RunService").RenderStepped:Connect(function()
		VM.Head.CFrame = workspace.CurrentCamera.CFrame
	end)
	game.ReplicatedStorage.Events.RemoteEvents.AnimationInfo.OnClientEvent:Connect(function(sett)
		if sett.SWEPBASE == nil then
			print("homie dats nil my brudda")
		else
			print(sett.SWEPBASE)
			if sett.SWEPBASE == "FIST" then
				local a, b = AnimService:LoadAnimTable(game.ReplicatedStorage.Animations.VM_ANIMATIONS.FIST:GetChildren(), hum, VM)
				local Idle = AnimService:DecodeAnimTable(a, b, "Idle")
				local function IdleAnim()
					Idle.Looped = true
					Idle:Play()
				end	
				IdleAnim()
			end
		end
	end)
end)

MODULE SCRIPT HERE

local module = {}

function module:LoadAnimTable(tab, hum)
	local ANIMATABLE = {}
	local ANIMATABLEPOS = {}
	for i, v in pairs(tab) do
		table.insert(ANIMATABLE, 1, hum:LoadAnimation(v))
		table.insert(ANIMATABLEPOS, 1, v.Name)
	end
	return ANIMATABLE, ANIMATABLEPOS
end

function module:DecodeAnimTable(animtable, animtablepos, returnval)
	local counter = 1
	local result = nil

	local attempt = table.find(animtablepos, returnval)
	if attempt ~= nil then
		for i, v in pairs(animtable) do
			if counter == attempt then
				result = v
				break
			else
				counter = counter + 1
			end
		end
	end

	return result
end

return module

It looks like you have a problem playing animations when the viewmodel is set to nil.

Basically, the error is saying the viewmodel has to be in workspace to play the animation. The problem is, you're setting the model's parent to nil. Here's a way you might be able to solve that.

local dead = false

game.Players.LocalPlayer.Character.Humanoid.Died:Connect(function()
	dead = true
	viewmodel.Parent = nil
end)

--//When you're about to play animations do:

if dead == false then --//If we're not dead
	anim:Play() -- play
else --//If we're ded
	print("player is ded")
	delay(2, function() -- Set dead back to false after a bit.
		dead = false
	end)
end

I'm pretty sure this isn't the best way to solve it, but it does the job.

Let me know if you have any issues, questions or concerns.

YES YES YES YES! THE SOLUTION IS TO RESET YOUR SCRIPTS WHEN YOU DIE!!!!
