Knockback

[slender kraken]

i am really struggeling with creating knockback or finding a way to add velocity to the player without them either getting faster in the air, flinging after the velocity, the velocity being way too weak. how or with which part can i create smooth and working knockback please help

[dire ether]

the easiest way would be to use bodyVelocity

[slender kraken]

body velocity flings

** You are now Level 1! **

[dire ether]

not if u do it properly

local bv = Instance.new("BodyVelocity")
bv.MaxForce, bv.Velocity = Vector3.new(5e4,5e2,5e4),plr.Character.HumanoidRootPart.CFrame.lookVector * 10
bv.Parent = hit.Parent.HumanoidRootPart
game.Debris:AddItem(bv,0.16)

this worked fine for me

I used that before it was working weird

like you fly when you hit a wall

[slender kraken]

alright ima try but what are the numbers in the vector3.new? 5e4 5e2?

[orchid stream]

they are just very big numbers

ig

[dire ether]

mines worked perfectly

scientific notation

bv.MaxForce = Vector3.new(50000, 500, 50000)

[orchid stream]

I use linear velocity now, it works perfectly for me

[dire ether]

basically this

[dire ether]

this is better

im just saying this the easiest way

[orchid stream]

body velocity is depreciated

[orchid stream]

yes, its easiest

[dire ether]

if u got time u should learn linear velocity

defo be useful

[orchid stream]

I just learned it through the roblox platformer template

[dire ether]

i mean it really isnt complicated

its almost the same thing

[orchid stream]

yes, but more properties and stuff

[orchid stream]

and attachements confused me at first but now, its good

[dire ether]

-- you need to define the player first
local HRP = player.Character.HumanoidRootPart

local Part = Instance.new("Part", workspace) -- the part to move
Part.CFrame = HRP.CFrame * CFrame.new(0,0,-3) -- Putting the part infront of the player

local Attachment = Instance.new("Attachment", Part) -- the attachment used in Linearvelocity

local LV = Instance.new("LinearVelocity", Attachment) -- creating the linear velocity
LV.MaxForce = math.huge -- no need to worry about this
LV.VectorVelocity = HRP.CFrame.lookVector * 100 -- change 100 with how fast you want the projectile to go
LV.Attachment0 = Attachment -- setting the attachment

game.Debris:AddItem(Part, 2) -- deletes the moving part after 2 second

[orchid stream]

it will still flung the player

you need to do some maths

[slender kraken]

how can i prevent the player from flinging?

because i currently use linearvelocity but it flings

[orchid stream]

lemme send you my roll script

its easy

local ROLL_DURATION = 0.2
local ROLL_FORCE = 100
local ROLL_COOLDOWN = 5

local Roll = {}

function Roll.Start(plr : Player, track : AnimationTrack, sound : Sound    )
    
    if not canRoll then return end
    canRoll = false
    
    task.delay(ROLL_COOLDOWN, function()
        canRoll = true
    end)
    
    local char = plr.Character or plr.CharacterAdded:Wait()
    local Humanoid = char:WaitForChild("Humanoid")
    local hrp : BasePart = char:WaitForChild("HumanoidRootPart")
    

    local attachment = Instance.new("Attachment")
    attachment.Parent = hrp
    
    local linearVelocity = Instance.new("LinearVelocity")
    linearVelocity.Attachment0 = attachment :: Attachment
    linearVelocity.RelativeTo = Enum.ActuatorRelativeTo.Attachment0
    linearVelocity.MaxForce = 1500 * hrp.AssemblyMass
    linearVelocity.VectorVelocity = Vector3.new(0, 0, - ROLL_FORCE)
    linearVelocity.Parent = hrp

    local sound = sound:Clone()
    sound.Parent = hrp
    
    track:Play()
    sound:Play()
    
    
    game.Debris:AddItem(linearVelocity, ROLL_DURATION)
    game.Debris:AddItem(sound, ROLL_DURATION)
    

end
return Roll ```
