Tornado not knocking back

Help and Feedback Scripting Support
#1

I’m currently creating a tornado that when touched it knocks the player back, but for some reason, it doesn’t activate when touched. Could someone help?

The script is a local script inside of a part.

function onTouch(part) 
    local humanoid = part.Parent:FindFirstChild("Humanoid") 
    local character = part.Parent
    if character and character:FindFirstChild("HumanoidRootPart") then 
        local bodyVelocity = Instance.new("BodyVelocity")
        bodyVelocity.Velocity = Vector3.new(50, 0, 0) 
        bodyVelocity.Parent = character.HumanoidRootPart
        game.Debris:AddItem(bodyVelocity, 0.5) -- removing force after 0.5 seconds    
        print("HIT TORNADO")
    end
    if humanoid then    -- if a humanoid exists, then
        humanoid.Health = humanoid.Health - 50    -- damage the humanoid
    end 
end

script.Parent.Touched:connect(onTouch)

just to make sure, it doesnt print out the “tornado hit” part? also, try making script.Parent.Transparency = 0.5 just for testing. you can see if youre even hitting it. maybe the part is unanchored and fell down, or isnt welded to the tornado.

BodyVelocity is deprecated, you should use LinearVelocity instead.

Something like this:

local attachment = Instance.new("Attachment")
attachment.Parent = character.PrimaryPart
		
local linVel = Instance.new("LinearVelocity")
linVel.VectorVelocity = Vector3.new(50, 0, 0)
linVel.Attachment0 = attachment
linVel.MaxForce = 100000
linVel.Parent = character.PrimaryPart
game.Debris:AddItem(linVel, .5)

Local scripts don’t work in the workspace. Switch it to a server script and use LinearVelocity since Body velocity is deprecated.

function onTouch(part) 
    local humanoid = part.Parent:FindFirstChild("Humanoid") 
    local character = part.Parent
    if character and character:FindFirstChild("HumanoidRootPart") then 
        local LV = Instance.new("LinearVelocity")
        LV.MaxForce  = math.huge
        LV.VectorVelocity = -character.HumanoidRootPart.CFrame.LookVector * 50 —- nice addition to knock the player *backwards*
        LV.Parent = character.HumanoidRootPart
        game.Debris:AddItem(bodyVelocity, 0.5) -- removing force after 0.5 seconds    
        print("HIT TORNADO")
    end
    if humanoid then    -- if a humanoid exists, then
        humanoid.Health = humanoid.Health - 50    -- damage the humanoid
    end 
end

script.Parent.Touched:connect(onTouch)

on top of this i recommend adding a debounce
the player is going to be touching this with multiple parts (right leg, left leg), which all count as touch
this will run onTouch() multiple times a second, instantly killing the player since your damage is so high

Thank you for the advice but I thought it too trivial for this occasion since I’m providing an example on how to use linear velocity. The OP will probably account for this later on
