How would I go about creating a controllable ragdoll-character?

What do you want to achieve? Keep it simple and clear!

I would like to have the player’s character be a ragdoll permanently, but, still have the ability to walk around and jump. (Similar to the game characters in Ragdoll Mayhem.)

What is the issue? What solutions have you tried so far?

I have no idea where to begin, I’ve tried looking into how people have made those “ragdoll on death scripts,” but I don’t know how I would go about letting the player be in that state while keeping the ability to control their character.

Any ideas on how I could do this is appreciated, thank you for your help!

I have a ragdoll script you can walk around and everything, but when you die it ragdolls Here is the script

 local character = script.Parent

function recurse(root,callback,i)
	i= i or 0
	for _,v in pairs(root:GetChildren()) do
		i = i + 1
		callback(i,v)
		
		if #v:GetChildren() > 0 then
			i = recurse(v,callback,i)
		end
	end
	
	return i
end

function ragdollJoint(part0, part1, attachmentName, className, properties)
	attachmentName = attachmentName.."RigAttachment"
	local constraint = Instance.new(className.."Constraint")
	constraint.Attachment0 = part0:FindFirstChild(attachmentName)
	constraint.Attachment1 = part1:FindFirstChild(attachmentName)
	constraint.Name = "RagdollConstraint"..part1.Name
	
	for _,propertyData in next,properties or {} do
		constraint[propertyData[1]] = propertyData[2]
	end
	
	constraint.Parent = character
end

function getAttachment0(attachmentName)
	for _,child in next,character:GetChildren() do
		local attachment = child:FindFirstChild(attachmentName)
		if attachment then
			return attachment
		end
	end
end

character:WaitForChild("Humanoid").Died:connect(function()
	local camera = workspace.CurrentCamera
	if camera.CameraSubject == character.Humanoid then--If developer isn't controlling camera
		camera.CameraSubject = character.UpperTorso
	end

	--Make it so ragdoll can't collide with invisible HRP, but don't let HRP fall through map and be destroyed in process	
	character.HumanoidRootPart.Anchored = true
	character.HumanoidRootPart.CanCollide = false

	--Helps to fix constraint spasms
	recurse(character, function(_,v)
		if v:IsA("Attachment") then
			v.Axis = Vector3.new(0, 1, 0)
			v.SecondaryAxis = Vector3.new(0, 0, 1)
			v.Rotation = Vector3.new(0, 0, 0)
		end
	end)
	
	--Re-attach hats
	for _,child in next,character:GetChildren() do
		if child:IsA("Accoutrement") then
			--Loop through all parts instead of only checking for one to be forwards-compatible in the event
			--ROBLOX implements multi-part accessories
			for _,part in next,child:GetChildren() do
				if part:IsA("BasePart") then
					local attachment1 = part:FindFirstChildOfClass("Attachment")
					local attachment0 = getAttachment0(attachment1.Name)
					if attachment0 and attachment1 then
						--Shouldn't use constraints for this, but have to because of a ROBLOX idiosyncrasy where
						--joints connecting a character are perpetually deleted while the character is dead
						local constraint = Instance.new("HingeConstraint")
						constraint.Attachment0 = attachment0
						constraint.Attachment1 = attachment1
						constraint.LimitsEnabled = true
						constraint.UpperAngle = 0 --Simulate weld by making it difficult for constraint to move
						constraint.LowerAngle = 0
						constraint.Parent = character
					end
				end
			end
		end
	end
	
	ragdollJoint(character.LowerTorso, character.UpperTorso, "Waist", "BallSocket", {
		{"LimitsEnabled",true};
		{"UpperAngle",5};
	})
	ragdollJoint(character.UpperTorso, character.Head, "Neck", "BallSocket", {
		{"LimitsEnabled",true};
		{"UpperAngle",15};
	})
	
	local handProperties = {
		{"LimitsEnabled", true};
		{"UpperAngle",0};
		{"LowerAngle",0};
	}
	ragdollJoint(character.LeftLowerArm, character.LeftHand, "LeftWrist", "Hinge", handProperties)
	ragdollJoint(character.RightLowerArm, character.RightHand, "RightWrist", "Hinge", handProperties)
	
	local shinProperties = {
		{"LimitsEnabled", true};
		{"UpperAngle", 0};
		{"LowerAngle", -75};
	}
	ragdollJoint(character.LeftUpperLeg, character.LeftLowerLeg, "LeftKnee", "Hinge", shinProperties)
	ragdollJoint(character.RightUpperLeg, character.RightLowerLeg, "RightKnee", "Hinge", shinProperties)
	
	local footProperties = {
		{"LimitsEnabled", true};
		{"UpperAngle", 15};
		{"LowerAngle", -45};
	}
	ragdollJoint(character.LeftLowerLeg, character.LeftFoot, "LeftAnkle", "Hinge", footProperties)
	ragdollJoint(character.RightLowerLeg, character.RightFoot, "RightAnkle", "Hinge", footProperties)
	
	--TODO fix ability for socket to turn backwards whenn ConeConstraints are shipped
	ragdollJoint(character.UpperTorso, character.LeftUpperArm, "LeftShoulder", "BallSocket")
	ragdollJoint(character.LeftUpperArm, character.LeftLowerArm, "LeftElbow", "BallSocket")
	ragdollJoint(character.UpperTorso, character.RightUpperArm, "RightShoulder", "BallSocket")
	ragdollJoint(character.RightUpperArm, character.RightLowerArm, "RightElbow", "BallSocket")
	ragdollJoint(character.LowerTorso, character.LeftUpperLeg, "LeftHip", "BallSocket")
	ragdollJoint(character.LowerTorso, character.RightUpperLeg, "RightHip", "BallSocket")
end)

If you know how to change things here you can go ahead and do it And if you don't know where to put it then go starterplayer and go StarterCharacterScripts and set it as a script

If this is not you are looking for then I don't know what you are

Hope this helped
