ApplyForce to character onTouch a part do not work

[Studio_NK]

I’ve been trying to do this so simple thing for a few days now, the example from the documentation doesn’t work, the scripts from the assistant don’t work, it’s strange because when the script applies an impulse after pressing a key on the keyboard then everything works nice, only not when I set it in the onTouch script in the object.

This one is from documentation;

local volume = script.Parent

local function onTouched(other)
	local impulse = Vector3.new(0, 2500, 0)
	local character = other.Parent
	local humanoid = character:FindFirstChildWhichIsA("Humanoid")
	if humanoid and other.Name == "LeftFoot" then
		other:ApplyImpulse(impulse)
		print("touched")
	end
end

volume.Touched:Connect(onTouched)

Knockback with humanoids is actually 3 times as hard as you need to account for humanoid counterforces (the resist force) and network ownership. So the steps for a local script will be different.

Here is an example with .AssemblyLinearVelocity you can swap it out with apply impulse as well it will achieve a similar effect.

Is there any way to make this knockback smoother/less laggy?

So I have done some testing since this is a frequent recurring and interesting topic. So I have done testing with the server network ownership method, the only cons I see is that it’s not smooth for the victim perspective. Video testing, with 0.25 seconds incoming network replication lag: Video uses: .AssemblyLinearVelocity += knockbackVelocity (simple instantaneous velocity method) Humanoid platformstand (to disable humanoid physics interference) Network ownership on serve…

1. So why this Creating Moving Objects | Documentation - Roblox Creator Hub showing it should just work as it is?

2. I made this way I created RemoteEvent, then in script under touched part I wrote

local reevent = game.ReplicatedStorage.REimpuls
local part = script.Parent
local touchOnce = 1

part.Touched:Connect(function(characterpart)
	local character = characterpart.Parent
	if character:FindFirstChild("Humanoid") and touchOnce == 1 then
		touchOnce = 0
		local player = game.Players:GetPlayerFromCharacter(character)
		reevent:FireClient(player)
		task.wait(5)
		touchOnce = 1
	end
end)

and in localscript under StarterPlayerScripts I wrote

local reevent = game.ReplicatedStorage.REimpuls


reevent.OnClientEvent:Connect(function()
	local player = game.Players.LocalPlayer
	local character = player.Character
	local impulse = Vector3.new(0, 1500, 0)
	local humanoid = character:FindFirstChildWhichIsA("Humanoid")
	if humanoid  then
		character.HumanoidRootPart:ApplyImpulse(impulse)
	end
end)

And it works. Is this a insecure method?
