need help with rotating spear

[wooden tree]

I'm trying to attach a spear to my arm so it matches the arm's position and the root's orientation, ensuring it always points forward during animations. I’ve tried using AlignRotations and AlignPositions, but there's lag in position/rotation. I want to avoid using a RunService loop on each client to adjust the Motor6D, as this would still result in inaccurate server-side hitboxes.

I’ve attached a video showing what I want.

Weld constraint

[wooden tree]

ill try, ty

[wooden tree]

how would i update the rotation then?

[umbral oasis]

Hhm?

You want it to always face forward

[wooden tree]

i have this rn, with a weldconstraint the rotation still changes when the arms rotation changes

if tool:GetAttribute("RootRelative") then
    local weldConstraint = Instance.new("WeldConstraint", weaponGrip)
    tool.Handle.CFrame = CFrame.new(weaponGrip.Position, weaponGrip.Position + root.CFrame.LookVector)
    weldConstraint.Part0 = weaponGrip
    weldConstraint.Part1 = tool.Handle
else

theres no difference from using a weldconstraint and a motor6d in my use case

since weldconstraints use cframes for offset it also rotates along

[umbral oasis]

I don't understand

How could the spear rotation not change

If the arm is moving

[wooden tree]

i want it to not rotate

its rotating with the arm rn

i want it to always look in the same direction as the rootpart instead

[umbral oasis]

I think its because its a tool handle

And they always grip to one arm or the other

You could try weld it instead to the root part aswell

To see if that change anything

[umbral oasis]

Also it would help if I could open the video

Cuz

It doesn't work

[wooden tree]

oh

[umbral oasis]

When I click on it

[wooden tree]

yeah wrong file i think

just the way spears work in deepwoken

[umbral oasis]

Could you send a clip of what yours is looking like

[wooden tree]

sure

there u go

[umbral oasis]

Ok don't name the tool handle

I mean

Change the name if the handle

Of*

[wooden tree]

i weld it manually

[umbral oasis]

To 'handle'

[wooden tree]

using a m6d

i automatically destroy the rightgrip that gets created when a tool gets added

heres the code i use for attaching it:

if toolInstance then
    local rightArm = player.Character:FindFirstChild("Right Arm")

    local root = player.Character.HumanoidRootPart

    local tool = toolInstance:Clone()
    tool.Parent = player.Character

    local weaponGrip = game.ReplicatedStorage.Assets.WeaponGrip:Clone()
    weaponGrip.Parent = tool

    local m6d = Instance.new("Motor6D")
    m6d.Part0 = rightArm
    m6d.Part1 = weaponGrip
    m6d.C1 = CFrame.new(0,1,0)
    m6d.Parent = weaponGrip

    if rightArm:FindFirstChild("RightGrip") then
        rightArm.RightGrip:Destroy()
    end
        --[[
        if tool:GetAttribute("RootRelative") then
            
        else

        end    ]]

    local weld = Instance.new("Weld")
    weld.Part0 = weaponGrip
    weld.Part1 = tool.Handle
    weld.C1 = tool.Grip
    weld.Parent = tool

    if WeaponType then -- this stuff isnt important
        tool:SetAttribute("WeaponType", WeaponType)
        player.Character.Humanoid:SetAttribute("WeaponType", WeaponType)
        animationsModule.Equip(player, "Weapon", WeaponType)
    end
else
    warn("Tool or FallBackTool not found in ServerStorage.")
end

Ye try change the name of the Handle

To anything else

[wooden tree]

why

[umbral oasis]

The handle is welded to the players arm

[umbral oasis]

And you are welding the weapon Grip to the handle

Idk if it will fix it or not

But you should try

[wooden tree]

??

[umbral oasis]

Delete the part where it welds it to the handle

[jovial turret]

** You are now Level 26! **

[umbral oasis]

And test

[wooden tree]

😭

then the tool just falls to the floor

the weapongrip is just a part that i use so that i can easily attach each weapon at the same spot

[umbral oasis]

weld constraint it to the rootPart

And offset its cframe a bit to the right

So it lines up with the players hand

[wooden tree]

i had that earlier

but

okay

[umbral oasis]

without the part that does the welding to handle

[wooden tree]

dawg

then the weapon just stays in place if my arm moves

i want its position to still match that of the arm

[umbral oasis]

Hmmm

I'm actually out of ideas

Weld contrasting to the arm wouldn't work cuz weld constraints dont change its position

Welding to the arm would make it position with the arm but change direction

You tried alignment orientation right?

[wooden tree]

i could use alignrotation and alignposition, but id have to do it on each client

and idk i would get an accurate hitbox that way

[umbral oasis]

Hitboxing should always be done on client

With server sanity checks

[wooden tree]

fr?

[umbral oasis]

Yes

[wooden tree]

the way i handle it rn is still instant

but its on the server

[umbral oasis]

If you use server its fine but most games do client

Unless you want to make a server script which makes the align orientation

[wooden tree]

i can just fire all the clients when a spear weapon gets equipped

but its not ideal

and id still have to align the position in some way
