Ragdoll not working on NPCs, works perfectly fine on players

Help and Feedback Scripting Support

#1

The script works fine in the player version, but after a random amount of time for NPCs it causes their torso to kinda not move or whatever. I even tried using the player version on the NPCs instead and it just had the same issues.

And I know in the video the ragdoll bugs out after I use my grab, but that was just inconvenient timing. I tried without using the grab and it still has the same issue.

Nevermind you actually do remove it

I know you add them in your script but check to see if the BallSocketConstr. etc are in the character after you notice the issue.

Cant seem to find any other probable cause

I tried settings the Humanoid.PlatformStand = true when they are ragdolled and false when they arent but even though it works, it ends up flinging them when they get up sometimes.

function Ragdoll(value: boolean)
	if value then
		Humanoid.PlatformStand = true
		Humanoid:ChangeState(Enum.HumanoidStateType.Ragdoll)
		Humanoid:SetStateEnabled(Enum.HumanoidStateType.GettingUp, false)
		replaceJoints()
		push()
	else 
		Humanoid.PlatformStand = false
		resetJoints()
		Humanoid:ChangeState(Enum.HumanoidStateType.GettingUp)
	end
end

Though the issue barely happens so I’ll just keep it like that. (Nevermind it happens way too often)
