Ragdoll that has attachments attached to humanoidrootpart dies when the ragdoll state is toggled

Help and Feedback Scripting Support
#1

Hey–I want to figure out why my ragdoll system makes humanoids die when the ball-socket constraints are attached to the humanoidrootpart but it looks completely normal

1: Humanoid dies when ragdoll state is enabled

2: Everything looks completely normal

I tried looking at other posts on devforum and found no solutions and I attempted to fix it myself but ended up breaking it even more.

Here’s my code:

local respawnable = true
local respawntime = 0
if respawnable == true then
	respawntime = 15
	respawnclone = script.Parent:Clone()
end

local character = script.Parent
local humanoid = character.Humanoid
--humanoid:SetStateEnabled(Enum.HumanoidStateType.FallingDown, false)
--humanoid:SetStateEnabled(Enum.HumanoidStateType.GettingUp, false)
local hrp = character.HumanoidRootPart
humanoid.BreakJointsOnDeath = false --MANDATORY
local jointsfolder = script.Constraints

local ragdolled = character.Ragdolled
local armballcolliders = false
local legballcolliders = false

local randomdeathfaces = {"4820464519", "4841508676", "2805269620", "9605698115", "9352717834", "33328967", "82908315", "7236332343", "255719185", "14484043271"}
local randomdeathsounds = {"6927884261", "6932519682", "8930566431", "2299243257", "877221802", "4164190231", "58435367"}
local function deathstuff()
	local face = character.Head.face
	face.Texture = "rbxassetid://" .. randomdeathfaces[math.random(#randomdeathfaces)]
	local sound = Instance.new("Sound", character.Head)
	sound.Volume = 0.5
	sound.SoundId = "rbxassetid://" .. randomdeathsounds[math.random(#randomdeathsounds)]
	sound:Play()
end

local function setupcollisionparts(char : Model)
	for _, v in ipairs(char:GetChildren()) do
		if v:IsA("BasePart") and v.Name ~= "HumanoidRootPart" then
			v.CollisionGroup = "ragdollcollidersnoc"

		end
	end
end

This code is messy as I’m not an experienced developer

I think it may be a problem with Roblox’s physics but I would need confirmation

I am not sure about the issue
i can only think the issue was attaching the constraints to the humanoidrootpart will cause issues with character movements have you tries Torso and kept the humanoidrootpart connected?

Have you tried turning off “requiresneck” on the humanoid properties? also you should probably put the attachments into the torso instead

I found out it works better if I attach them to the torso rather to the humanoidrootpart, thank you
