Roblox，某个零件与玩家接触会造成伤害

我的代码：

local UIS = game:GetService("UserInputService")
local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()
local Activation =
Instance.new("Sound",game.Players.LocalPlayer.Character.Head)
local char = Player.Character
local hum = char.Humanoid
local root = char.HumanoidRootPart

UIS.InputBegan:Connect(function(input)
if input.KeyCode == Enum.KeyCode.F then
local animation = Instance.new("Animation")
animation.AnimationId = "rbxassetid://1581972610"
local animTrack = hum:LoadAnimation(animation)
animTrack:Play()
Activation.SoundId = "rbxassetid://1581091676" --播放万花筒写轮眼激活音效。
Activation:Play()
wait(0.3)
game.Players.LocalPlayer.Character.Head.face.Texture = "rbxassetid://76285632" --按下 F 键时，面部纹理变为写轮眼贴图。
game:GetService("Chat"):Chat(Player.Character.Head, "万花筒写轮眼！")
end
end)

UIS.InputBegan:Connect(function(input)
if input.KeyCode == Enum.KeyCode.R then
Activation.SoundId = "rbxassetid://1580990602" --播放天照写轮眼激活音效。
Activation:Play()
game:GetService("Chat"):Chat(Player.Character.Head, "天照！")
local Target = Instance.new("Part") --创造一个零件
Target.CFrame = Mouse.Hit; --使零件在鼠标当前位置生成
Target.Parent = game.Workspace
Target.Transparency = 1
Target.Anchored = true
Target.CanCollide = false

local Amaterasu = Instance.new("Fire")
Amaterasu.Parent = game.Workspace.Part
Amaterasu.Color = Color3.new(0,0,0)
Amaterasu.SecondaryColor = Color3.new(0,0,0) --天照写轮眼属性
Amaterasu.Size = 25

local R = Instance.new("RocketPropulsion") --火箭推进器，将其父对象设置为天照写轮眼
R.Parent = Amaterasu
R.MaxThrust = 300
R.ThrustP = 30
R:Fire()
end
end)

 UIS.InputBegan:Connect(function(input)
if input.KeyCode == Enum.KeyCode.G then
game.Players.LocalPlayer.Character.Head.face.Texture = "rbxassetid://22557247" --按下 G 键时，面部纹理恢复为正常（留空白需修复）
end
end)

我正在处理脚本中的第二个功能，即按下“r”键时激活的功能。通过按下“r”键，该功能将在鼠标当前位置生成带有火焰的零件。

这一切都很好。我想让所生成的火焰伤害任何接触它的玩家，为了给予100点伤害，我要在此设置该功能。
