How do I apply knockback by changing Setting Network Owner?

[ford200001 (Ford)]

I’m trying to have the player that a sword hits be knocked back.

It just does not work. I have tried VectorForces, ApplyImpulse, and Velocity but no matter what I do I cannot get it to work. The furthest I’ve gotten was getting a Rig to be knocked back, but it has never worked with an actual player.

I read that I need to change the network ownership, but I haven’t gotten that to work. I may be doing it wrong.

local players = game:GetService("Players")

local tool = script.Parent
local blade = tool.Handle.Sword_Part

local animationsFolder = tool.Animations

local isHit = false

local debounce = false
local debounceTime = 1

local knockbackForce = 100

local function bladeTouched(hit)
	if hit.Parent:FindFirstChild("Humanoid") and debounce then
		if isHit then return end
		
		isHit = true
		
		print(hit)
		
		local humanoid = hit.Parent.Humanoid
		local humanoidRootPart = hit.Parent:FindFirstChild("HumanoidRootPart")

		if humanoid and humanoidRootPart then
			local character = tool.Parent
			local ogVelocity = humanoidRootPart.Velocity
			
			local player = players:GetPlayerFromCharacter(humanoidRootPart.Parent)
			
			humanoidRootPart:SetNetworkOwner(player)

			humanoidRootPart.Velocity = (character.HumanoidRootPart.CFrame.LookVector * knockbackForce)
			
			wait(debounceTime)
			
			humanoidRootPart:SetNetworkOwner(nil)
			humanoidRootPart.Velocity = ogVelocity
			
			isHit = false
		end
	end
end

local function onActivated()
	if not debounce then
		local character = tool.Parent
		local humanoid = character.Humanoid
		
		local anim = animationsFolder.Animation
		local animTrack = humanoid:LoadAnimation(anim)
		
		animTrack:Play()
		
		debounce = true
		wait(debounceTime)
		debounce = false
	end
end

blade.Touched:Connect(bladeTouched)
tool.Activated:Connect(onActivated)

Any help at all will be appreciated. Thanks!!

For Knockbacks, I simply fire a RemoteEvent to the player’s client and let the client perform the knockback on its character

Where would you put the local script for that? In the tool?

[HugeCoolboy2007 (omega)]

I place it under StarterCharacterScripts

How would I knock the player back though? Using velocity? And should I send info like the humanoidRootPart to the client from the server?

In my use case, I use AssemblyLinearVelocity on the character’s HumanoidRootPart:

-- Example of what I do
Character.HumanoidRootPart.AssemblyLinearVelocity = -(From - CharacterPosition).Unit * Force

-- of course, what's actually being set as the value depends on your use case.
-- So, I believe for your case, it would be:
Character.HumanoidRootPart.AssemblyLinearVelocity = Character.HumanoidRootPart.CFrame.LookVector * Force

For your case, you should send the client the amount of force to apply on itself
