Hello I'm working on this rayscast script, but whenever it hits a hat it deals no damage to the characters health, and I don't know how to fix it. Please help; here is the script ( look at line 11 to 17):

local Tool = script.Parent --Set a variable for the tool.
local User --Create a nil value for the character which we can't find yet.
local enabled = true --The gun is ready
Tool.Equipped:connect(function(mouse) --When it's equipped fire a function.
mouse.Icon = "http://www.roblox.com/asset/?id=90302277" -- set the crosshair asset to the mouse icon
User = Tool.Parent --Set the User variable to the character of the person using the tool.
mouse.Button1Down:connect(function() --When the left mouse button is clicked fire a function.
if enabled == true then --If the gun is ready then
script.Parent.ShotSound:play() -- play the sound
local Ray = Ray.new(Tool.Handle.CFrame.p,(mouse.Hit.p-Tool.Handle.CFrame.p).unit*300) --Make a the ray.
local Hit,Position = game.Workspace:FindPartOnRay(Ray,User) --Check for collisions along the ray.
if Hit then --If it hits something.
if Hit.Parent:FindFirstChild("Humanoid") then --If the thing the ray hit has a humanoid.
local Player = game.Players:GetPlayerFromCharacter(Hit.Parent)
if(Player)then
if Player.TeamColor ~= game.Players:GetPlayerFromCharacter(script.Parent.Parent).TeamColor then -- if the hit players doesn't share the same team as the shooter then
Hit.Parent.Humanoid:TakeDamage(100) --Do 100 damage if they don't have a forcefield.
mouse.Icon = "http://www.roblox.com/asset/?id=90302320" -- set the hitmarker asset to the mouse icon
wait (3) -- wait 3 seconds
mouse.Icon = "http://www.roblox.com/asset/?id=90302277" -- set the crosshair asset to the mouse icon
end --End the humanoid check.
end --End the hit check.
end -- end the conditonal statement
end -- end the conditonal statement
local RayPart = Instance.new("Part",User) --Create a part in the user.
RayPart.Name = "RayPart" --Set its name.
RayPart.BrickColor = BrickColor.new("White") --Set its color.
RayPart.Transparency = 0.5 --Set its transparency.
RayPart.Anchored = true --Set whether it will fall or not.
RayPart.CanCollide = false --Set whether people can walk though it or not.
RayPart.TopSurface = Enum.SurfaceType.Smooth --Make it smooth on the top.
RayPart.BottomSurface = Enum.SurfaceType.Smooth --Make it smooth on the bottom.
RayPart.formFactor = Enum.FormFactor.Custom --Make it so it can be small.
local Distance = (Position-Tool.Handle.CFrame.p).magnitude --Find the distance between the click and the gun.
RayPart.Size = Vector3.new(0.2,0.2,Distance) --Set its size to the distance.
RayPart.CFrame = CFrame.new(Position,Tool.Handle.CFrame.p) * CFrame.new(0,0,-Distance/2) --Move it halfway.
game.Debris:AddItem(RayPart,0.1) --Add it to the debris.
enabled = false --The gun isn't ready
mouse.Icon = "http://www.roblox.com/asset/?id=90300354" -- set the reloading asset to the mouse icon
wait(7) --Wait for the gun to be ready
mouse.Icon = "http://www.roblox.com/asset/?id=90302277" -- set the crosshair asset to the mouse icon
enabled = true --The gun is ready
end -- end the conditonal statement
end) -- end the equipped function
end) -- end the clicked function

You can loop trought every characters, and see if the object it hitted a descendant of the character, example

(Say hit is the object it hit)

for i,v in pairs(game:service'Players':GetPlayers()) do
if hit:IsDescendantOf(v.Character) then
-- damage
end
end

Do I really need the loop or can I just use the IsDescdentOf method?

Well, the loop is to loop trought every character, so... yes, pretty much.

alternatively, you can include hats on the raycast ignore list.

Reading up on raycasting hopefully I will find an easier/more efficent way then the first reply was, and find out how to make the ray ignore, I should have done this before. *facepalm*
