I can't seem to get rid of the Humanoids body parts. I got this:
script.Parent.Humanoid.Died:connect(function() HumanIntel.Stop() wait(5) game:GetService("Debris"):AddItem(script.Parent,5) end)
but it doesn't work.
Are you trying to use ragdoll script? If so, this need to be placed into the ragdoll. If not, then look at if ~~~~~~~~~~~~~~~~~ HumanIntel ~~~~~~~~~~~~~~~~~ is correctly defined, and look to see if you're character is being auto spawned. (This is when the Character is spawned in after 3 seconds.) If the character is being autospawned, then Character Model will automatically be removed.
Alongside this, if the Humanoid Model is not a player, see what kind of script it has inside it, local or script?
