How do I destroy body parts?

Although you have the right idea, you cannot just type 'torso' or 'head' and the script automatically picks up on what you mean. You have to define on what you want to delete, also instead of using lines of code you can actually use a loop for this.

local NPC = script.Parent
local Humanoid = NPC:WaitForChild('Humanoid')

Humanoid.Died:Connect(function()
    for _,v in pairs(NPC:GetChildren()) do
        if v:IsA('BasePart') or v:IsA('MeshPart') or v:IsA('UnionOperation') -- check if its a part
            v:Destroy() -- destroy any parts found
        end
    end
end)

If you have any other questions feel free to comment below.

uh i guess i need to give the full script ;-;

local walk = script.Parent.Humanoid:LoadAnimation(script.Walking)
local throw = script.Parent.Humanoid:LoadAnimation(script.Throw)
local head = script.Parent.Head
local torso = script.Parent.Torso
local hrp = script.Parent.HumanoidRootPart
local tla =script.Parent.TopLeftArm
local tll = script.Parent.TopLeftLeg
local mla = script.Parent.MidLeftArm
local mll = script.Parent.MidLeftLeg
local bla = script.Parent.BotLeftArm
local bll = script.Parent.BotLeftLeg
local tra = script.Parent.TopRightArm
local trl = script.Parent.TopRightLeg
local mra = script.Parent.MidRightArm
local mrl = script.Parent.MidRightLeg
local bra = script.Parent.BotRightArm
local brl = script.Parent.BotRightLeg                                                                                                                               

wait(0.001)
walk:Play()

while true do
    wait(10)
    local e = Instance.new("Part",workspace)
    e.Shape = "Ball"
    e.Material = "Neon"
    e.Size = Vector3.new(18.93, 18.93, 18.93)
    e.BrickColor = BrickColor.new("Really red")
    e.CFrame = tla.CFrame
    local f = Instance.new("Part",workspace)
    f.Shape = "Ball"
    f.Material = "Neon"
    f.Size = Vector3.new(18.93, 18.93, 18.93)
    f.BrickColor = BrickColor.new("Really red")
    f.CFrame = tra.CFrame
    wait(0.0001)
    local eweld = Instance.new("Motor6D",e) 
    eweld.Part0 = e
    eweld.Part1 = tla
    local fweld = Instance.new("Motor6D")
    fweld.Part0 = f
    fweld.Part1 = tra
    wait(0.0001)
    throw:Play()
    wait(0.5)
    eweld:Destroy()
    fweld:Destroy()
    e.Touched:Connect(function(p)
        if p.Parent:FindFirstChild("Humanoid") then
            p.Parent.Humanoid.Health = p.Parent.Humanoid.Health -10
            e:Destroy()
        end
    end)
    f.Touched:Connect(function(p)
        if p.Parent:FindFirstChild("Humanoid") then
            p.Parent.Humanoid.Health = p.Parent.Humanoid.Health -10
            f:Destroy()
        end
    end)
end
`script.Parent.Humanoid.Died:Connect(function() 
    head:Destroy()
    torso:Destroy()
    hrp:Destroy()
    tla:Destroy()
    tra:Destroy()
    tll:Destroy()
    trl:Destroy()
    mla:Destroy()
    mra:Destroy()
    mll:Destroy()
    mrl:Destroy()
    bla:Destroy()
    bra:Destroy()
    bll:Destroy()
    bll:Destroy()
    end)

from line 61 to line 76 is the problem. `

if brl isn't the issue,as its spaced out. Here's a simple way I delete body parts when you click a button:

Using Local Script:

meep = game.Players.LocalPlayer.Character

script.Parent.MouseButton1Click:Connect(function()
       meep.Head:Destroy()
       meep.Torso:Destroy()
end)

it destroys the local player's head and torso (R6) . Hopefully this example helps you.
