Do you struggle with ragdolls? Do you need a new way of making ragdolls? Are you looking for a good ragdoll module? You should try this module out!
Introducing, Inverse Kinematics Ragdoll Module! This module uses my method of making IK Ragdolls. It’s the 2023 way of making ragdolls, It has better collisions and it’s less buggier than the previous method (BallSocketConstraint Method)

IK Ragdoll Module (DevXylo Method)
Module Guide:
Step 1 - Requiring the module.
You will need to require the module in order to use the functions.
local ragdollModule = require(game:GetService("ServerStorage"):WaitForChild("DevXylo's IK Ragdoll Method"))
Step 2 - Ragdolling the rig/player.
Now you’re simply going to call the function :IKRagdoll() and put in the rig/character in order to make it ragdoll.
local request = ragdollModule:IKRagdoll(game:WaitForChild("Players"):GetPlayers()[1].Character) -- This line is going to return a table full of parts, attachments and values, while ragdolling the rig/character.
local returnedTable
returnedTable = request -- The important table for Unragdolling.
Step 2 - Unragdolling/Rebuilding
Now you’re going to use the returnedTable variable to unragdoll/rebuild the rig/character.
ragdollModule:Rebuild(game:WaitForChild("Players"):GetPlayers()[1].Character, returnedTable)

This Module is BETA so feedback is always appreciated
Best regards, DevXylo.
Q/A:
Q1: Can you animate the ragdoll?
A1: I actually saw a topic where a Developer asked if you could animate the ragdoll. The answer is yes. The ragdoll edits the position of every limbs using Inverse Kinematics, so you can still animate the ragdoll.
Q2: Are there any bugs/glitches?
A2: Yes, there can be physics glitches and bugs, so don’t expect the module to be glitch-free.
