To ragdoll in a Roblox booth game, the usual method is to replace the character’s joints with physics constraints, often when a key is pressed or when the player is knocked down. A common setup is to set Humanoid.BreakJointsOnDeath = false, then convert Motor6D joints into BallSocketConstraint joints so the body can flop naturally.

Basic setup

  1. Put a script in the character or starter character scripts.
  2. Get the Humanoid and disable joint breaking on death.
  3. Loop through the character’s Motor6D joints.
  4. For each joint, create two Attachment objects and a BallSocketConstraint.
  5. Destroy the original Motor6D after creating the constraint.

Simple example

A very common pattern looks like this in Roblox Studio:

lua

local Character = script.Parent
local Humanoid = Character:WaitForChild("Humanoid")

Humanoid.BreakJointsOnDeath = false

Humanoid.Died:Connect(function()
	for _, Motor in pairs(Character:GetDescendants()) do
		if Motor:IsA("Motor6D") then
			local Attachment0 = Instance.new("Attachment")
			local Attachment1 = Instance.new("Attachment")
			local Constraint = Instance.new("BallSocketConstraint")

			Attachment0.Parent = Motor.Part0
			Attachment1.Parent = Motor.Part1
			Attachment0.CFrame = Motor.C0
			Attachment1.CFrame = Motor.C1

			Constraint.Attachment0 = Attachment0
			Constraint.Attachment1 = Attachment1
			Constraint.Parent = Motor.Parent

			Motor:Destroy()
		end
	end
end)

This is the standard “death ragdoll” approach shown in multiple Roblox tutorials and forum answers.

If you mean a keybind

Some games also let players ragdoll manually with a key like R. In that case, the client detects the key press, asks the server to ragdoll the character, and then the humanoid is put into a physics state briefly before returning to normal.

Booth game note

If by “booth game” you mean a specific Roblox experience, the ragdoll effect may already be built in or may be disabled by the game’s scripts. In that case, you usually cannot force it unless the game specifically provides a ragdoll button, emote, or knockdown mechanic.

What to try

  • Press the game’s own ragdoll or reset key if it has one.
  • Check the game’s controls or settings for emotes/physics.
  • If you are the developer, use the joint-to-constraint method above.

TL;DR: ragdolling in Roblox is usually done by disabling joint breaking and swapping Motor6D joints for BallSocketConstraint joints, either on death or through a keybind.
