Issues with NPC Ragdolling

Help and Feedback Scripting Support

#1

I have a ragdoll script that I’ve been using, however it’s had varying degrees of success. The script only triggers when an NPC reaches 1 HP, and will work fine in the first 30 or so seconds of the game like this:

However after those first 30 or so seconds, regardless of whether it’s the same NPC or not, instead of dropping to the ground, they’ll sort of hang suspended in place like this:

Any help on fixing this issue would be greatly appreciated. I’ll also attach the script below:

local Modules = game.ServerScriptService.Modules
local NPCHandler = require(Modules.NPCHandler)



local Character: Model = script.Parent
local Torso: BasePart = Character:WaitForChild("Torso")

local NPCID = Character.NPCID.Value
local NPCData = NPCHandler[NPCID]
local Size = NPCData.Appearance.Size



Character.Humanoid.BreakJointsOnDeath = false
Character.Humanoid.RequiresNeck = true 



local attachmentCFrames = {
	["Neck"] = {CFrame.new(0, Size * 1, 0, 0,Size * -1, 0,Size * 1, 0, -0, 0, 0,Size * 1), CFrame.new(0,Size * -0.5, 0, 0,Size * -1, 0,Size * 1, 0, -0, 0, 0,Size * 1)},
	["Left Shoulder"] = {CFrame.new(Size * -1.3,Size * 0.75, 0,Size * -1, 0, 0, 0,Size * -1, 0, 0, 0,Size * 1), CFrame.new(Size * 0.2,Size * 0.75, 0,Size * -1, 0, 0, 0,Size * -1, 0, 0, 0,Size * 1)},
