How to Disable Joints / Body parts Breaking Apart on Death?

There's A Property That The Humanoid Brings, Which Is Called BreakJointsOnDeath. If You Want To Disable It, Just Do This:

Local Script:

local plr = game.Players.LocalPlayer
local char = plr.Character or plr.CharacterAdded:Wait()
local hum = char:WaitForChild("Humanoid")
hum.BreakJointsOnDeath = false -- This Will Make So That The Joints Don't Break.

Server Script:

game.Players.PlayerAdded:Connect(function(plr)
       local char = plr.Character or plr.CharacterAdded:Wait()
       char:WaitForChild("Humanoid").BreakJointsOnDeath = false
end)

If You Want To Make A Ragdoll Script, You'll Have To Change Some Stuff, But This Is Basically What You Wanted To Do.

Have A Nice Day!
