i'm trying to make the player when press key f he will do the throwing animation and then throw a fire ball and it will deal damage to what it hits, and it worked but there's a problem sometime it doesn't damage at all and specially when i'm walking and throwing at the same time it doesn't deal damage at all , i tried to make the ball smaller and it actually worked the ball damaged normally as i want it but when the fireball size was big it didn't damage , i start testing and i think that's when the ball hit more than one thing (part) the script work normally and the ball deal damage but when the ball was big it was hitting more than one thing (part) at once and that what stopped it from dealing damage , i think that the problem but please check my code and help me.


1) Local Script inside (StarterPack) :

local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()
local RemoteEvent = game.Workspace.remoteEvents.fireLine
local RemoteEvent2 = game.Workspace.remoteEvents.fireLine2
local UIS = game:GetService("UserInputService")

local Debounce = false

UIS.InputBegan:connect(function(Input,mouse, x, y, z)
    local char = Player.Character


    if Input.KeyCode == Enum.KeyCode.F then
        --wait(1)
        if Debounce == true then return end
        Debounce = true
        if script.level.Value == 1 then
            local roll = Instance.new("Animation")
            roll.AnimationId = "http://www.roblox.com/asset/?id=2393690494"
            local animloader = char.Humanoid:LoadAnimation(roll)
            animloader:Play()
            wait(0.8)
            mouse = Mouse.Hit
            x = Mouse.Hit.p.x
            y = Mouse.Hit.p.y
            z = Mouse.Hit.p.z

            RemoteEvent:FireServer(mouse, x, y, z)
        end

        if script.level.Value == 2 then
            mouse = Mouse.Hit
            x = Mouse.Hit.p.x
            y = Mouse.Hit.p.y
            z = Mouse.Hit.p.z
            RemoteEvent2:FireServer(mouse, x, y, z)
        end

        wait(1)
        Debounce = false
    end
end)









2) Script inside (Workspace) :

Instance.new("BodyPosition", workspace)
game.Workspace.remoteEvents.fireLine.OnServerEvent:Connect(function(Player,mouse, x, y, z)

    local AlreadyTouched = false
    local Character = Player.Character or Player.CharacterAdded:wait()
    local FireLine = game.ReplicatedStorage.Kai.FireLine:Clone()
    FireLine.CanCollide = false
    FireLine.Parent = Character
    FireLine.CFrame = Character.HumanoidRootPart.CFrame*CFrame.new(-1.5,1,-3)

    local BV = Instance.new("BodyVelocity")
    BV.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
    BV.Velocity = (FireLine.Position - mouse.p).unit * -175

    BV.Parent = FireLine

    FireLine.Touched:Connect(function(Hit)
        local Humanoid = Hit.Parent:FindFirstChild("Humanoid")
        --if Humanoid == nil then Humanoid = Hit.Parent.Parent:FindFirstChild("Humanoid") end
        print(Hit.Name)
        --print("Hit.Parent.Parent: " , Hit)
        if Humanoid == nil and Hit.Name ~= "Terrain" then FireLine:Destroy() end
        if AlreadyTouched == false and Hit.Name ~= "Terrain" then
            AlreadyTouched = true
            if Humanoid.Parent.Name == Player.Name then
                Humanoid.Health = Humanoid.Health
            else
                Humanoid.Health = Humanoid.Health - Humanoid.MaxHealth/4
                FireLine:Destroy()
            end
        end
    end)

    wait(2)
    FireLine:Destroy()
end)

I can see the confusion in you, so I will explain why.

The problem is that the ball touched not only your character, but also your accessories.

In the script inside Workspace, when the fire ball touches a part, it fires. However, it came from your character, so it will touch your character first. However, it also touch the Handle of your accessories, causing it to find the Humanoid in its parent, which is the Accessory, not the character. Therefore, it couldn't find the Humanoid, thus destroying itself.

Here's a quick fix for you: Use the function Instance:IsDescendantOf(). This will check if the touched part is the descendant (instead of an immediate child) of an Instance, and in this case, your character.

--Script inside Workspace, FireLine.Touched event
FireLine.Touched:Connect(function(Hit)
    if Hit:IsDescendantOf(Character) then
        --if Hit is anywhere inside the Player's character, ignore
        return
    end
    local Humanoid = Hit.Parent:FindFirstChild("Humanoid")

    print(Hit.Name) --Ever wonder why it printed out "Handle" all the time? Now it's solved.

    if Humanoid == nil and Hit.Name ~= "Terrain" then
        FireLine:Destroy() 
    else --instead of "end" since this will continue the thread and therefore returns an error
        if AlreadyTouched == false and Hit.Name ~= "Terrain" then
            AlreadyTouched = true
            if Humanoid.Parent.Name ~= Player.Name then
                --is this the player?
                --no? take damage.
                Humanoid.Health = Humanoid.Health - Humanoid.MaxHealth/4
                FireLine:Destroy()
            end
        end
    end
end)
