Issues with applying a knock velocity to players

[wise sage]

I'm working on this combat system and it works perfectly except for the knockback, where it sometimes just doesn't actually apply it, sometimes it does, and sometimes it does it then rubberbands the player back to their position
It works perfectly with dummies so ill put a show case how it works for both
video has weird res because i was recording my studio screen and it didnt catch the explorer and what not

heres the code responsible

function ServerAxeClass:Knockback(victimCharacter, attackerCharacter)
    local attackerRoot = attackerCharacter:FindFirstChild("HumanoidRootPart")
    local targetRoot = victimCharacter:FindFirstChild("HumanoidRootPart")
    local targetHumanoid = victimCharacter:FindFirstChild("Humanoid")
    
    if not attackerRoot or not targetRoot or not targetHumanoid then return end
    
    local horizontalDirection = (targetRoot.Position - attackerRoot.Position) * Vector3.new(1, 0, 1)
    
    targetRoot:SetNetworkOwner(nil)
    targetHumanoid.PlatformStand = true
    targetHumanoid:ChangeState(Enum.HumanoidStateType.Physics)

    local impulse = (horizontalDirection.Unit + Vector3.new(0, 1.2, 0)).Unit * 100 * targetRoot.AssemblyMass

    targetRoot:ApplyImpulse(impulse)

    task.delay(0.4, function()
        if targetHumanoid then
            targetHumanoid.PlatformStand = false
            targetHumanoid:ChangeState(Enum.HumanoidStateType.Freefall)
            
            local player = Players:GetPlayerFromCharacter(victimCharacter)
            if player then targetRoot:SetNetworkOwner(player) end
            targetHumanoid.EvaluateStateMachine = true
        end
    end)
end

its due to the network owner being the servre

its the safest but it makes it choppy

set it to either the player with the axe or the guy getting kncok backed

and u can add some anti cheat or just leave it like that

[wise sage]

yeah i thought i could just give the client control and let them do it then do an anti cheat thing

[fluid lynx]

** You are now Level 1! **

[wise sage]

is that the only workaround?

also would it work if the ownership is shared between clients

[calm pewter]

I don't think u can share ownsership

[wise sage]

if 2 players get close to each other they share ownership to have better collisions

i think you see it in the video when the ownership thing turns red

[calm pewter]

isnt that the hitbox turning red

[wise sage]

oh no thats not hit boxee

thats the ownership viewer

built in roblox

Green is my client, white is server and red is shared

as for the other play it says server owns him but on his screen he sees his ownership colored

network owners down there

[calm pewter]

oh

if u don't wanna change network ownership then maybe

add a velocity to every character beforehand

and enable it when theyre hit

[wise sage]

like bodyvelocity?

[calm pewter]

maybe change all the parts to massless too to make the velocity act faster

one of these 2 i think

body velocity is deprecated

[wise sage]

ill try that out yeah

thank you very much

[wise sage]

has a big delay at the start and doesnt really work on players

[red pendant]

just apply the impulse on the client for players

Thats how I did knockback with ApplyImpulse

[wise sage]

yeah thats what i opted for thanks
