Localscript under StarterCharacterScripts loading late

Help and Feedback Scripting Support

Hello
I have a script below

local rs = game:GetService("ReplicatedStorage")
local plrs = game:GetService("Players")
local run = game:GetService("RunService")

local player = plrs.LocalPlayer
local char = player.Character or player.CharacterAdded:Wait()
local mouse = player:GetMouse()

local torso = char:WaitForChild("Torso")
local rightArm = char:WaitForChild("Right Arm")

local event = rs:WaitForChild("events"):WaitForChild("LightsaberMove")

local armOffset = torso.CFrame:Inverse() * rightArm.CFrame

-- weld to attach right arm to torso
local armWeld = Instance.new("Weld")
armWeld.Part0 = torso
armWeld.Part1 = rightArm
armWeld.Parent = rightArm

local rotCFrame -- store rotation data
local armPos -- store arm position relative to torso

-- update arm's position and rotation every frame
run.RenderStepped:Connect(function()
	local torsoPos = torso.Position
	local mouseHit = mouse.Hit.Position

	-- lock movement to y-z plane
	mouseHit = Vector3.new(torsoPos.X, mouseHit.Y, mouseHit.Z)

	-- calculate direction to mouse
	local lookAtCFrame = CFrame.lookAt(torsoPos, mouseHit)
	rotCFrame = CFrame.new(torsoPos) * CFrame.Angles(lookAtCFrame:ToEulerAnglesXYZ())

	-- store arm's relative position
	armPos = rightArm.CFrame.Position - torso.CFrame.Position

	-- update weld with new rotation
	armWeld.C0 = armOffset * torso.CFrame:toObjectSpace(rotCFrame)
end)

-- send rotation and position data to server
local function sendData()
	if rotCFrame and armPos then
		event:FireServer(rotCFrame, armPos, torso.CFrame)
	end
end

-- run continuously
while true do
	sendData()
	wait(0.05)
end

Works great on the first load, but after it loads a bit late, and breaks. However, the serverside of it works great even if it loads late on the client.

I would appreciate any insight on this.
thanks!

hi, im not sure what do you mean with this: ā€˜ā€˜Works great on the first load, but after it loads a bit late, and breaks.ā€™ā€™ because isnt spelled correctly, but i guess you mean when the player spawns. so, if im right, then basically this behavior is common when scripts do not properly handle the characterā€™s lifecycle, especially during respawns, so i recode your script, obviously fixing that issue, here:

local rs = game:GetService("ReplicatedStorage")
local plrs = game:GetService("Players")
local run = game:GetService("RunService")

local player = plrs.LocalPlayer
local char = player.Character or player.CharacterAdded:Wait()
local mouse = player:GetMouse()

local torso = char:WaitForChild("Torso")
local rightArm = char:WaitForChild("Right Arm")

local event = rs:WaitForChild("events"):WaitForChild("LightsaberMove")

local armOffset = torso.CFrame:Inverse() * rightArm.CFrame

-- Weld to attach right arm to torso
local armWeld = Instance.new("Weld")
armWeld.Part0 = torso
armWeld.Part1 = rightArm
armWeld.Parent = rightArm

local rotCFrame -- Store rotation data
local armPos -- Store arm position relative to torso

-- Function to initialize character components
local function initializeCharacter(character)
    torso = character:WaitForChild("Torso")
    rightArm = character:WaitForChild("Right Arm")
    armOffset = torso.CFrame:Inverse() * rightArm.CFrame

    -- Recreate the weld
    armWeld:Destroy()
    armWeld = Instance.new("Weld")
    armWeld.Part0 = torso
    armWeld.Part1 = rightArm
    armWeld.Parent = rightArm
end

-- Update arm's position and rotation every frame
run.RenderStepped:Connect(function()
    local torsoPos = torso.Position
    local mouseHit = mouse.Hit.Position

    -- Lock movement to y-z plane
    mouseHit = Vector3.new(torsoPos.X, mouseHit.Y, mouseHit.Z)

    -- Calculate direction to mouse
    local lookAtCFrame = CFrame.lookAt(torsoPos, mouseHit)
    rotCFrame = CFrame.new(torsoPos) * CFrame.Angles(lookAtCFrame:ToEulerAnglesXYZ())

    -- Store arm's relative position
    armPos = rightArm.CFrame.Position - torso.CFrame.Position

    -- Update weld with new rotation
    armWeld.C0 = armOffset * torso.CFrame:toObjectSpace(rotCFrame)
end)

-- Send rotation and position data to server
local function sendData()
    if rotCFrame and armPos then
        event:FireServer(rotCFrame, armPos, torso.CFrame)
    end
end

-- Run continuously
while true do
    sendData()
    wait(0.05)
end

-- Listen for character respawn
player.CharacterAdded:Connect(function(newCharacter)
    char = newCharacter
    initializeCharacter(char)
end)

Hey! thanks for the response.


Hereā€™s a video of the behavior with the script you posted as replacement.

Note that the hand is the only thing ā€œrotatingā€ from the script, Iā€™ve got a separate one mounting the sword onto the hand.

After respawning, I think that it jumps to the direction of the cursor regardless of the axis, Iā€™m not sure though.

so, still being an issue right?, i mean, i think that the issue is that the whole body is moving to the mouse, instead of just the arm, right?, thats what it happens now?

The behavior is in the video above, the arm rotates around the wrong axis or something/

the script is in StarterCharacterScripts so player.CharacterAdded would never fire since the script runs after the character gets added

Also you placed the event after a loop so it wouldnā€™t run anyway.

local rightArm = character:WaitForChild("Right Arm")
local rightShoulder = torso:FindFirstChild("Right Shoulder") or torso:FindFirstChild("RightShoulder")

if not rightShoulder or not rightShoulder:IsA("Motor6D") then

forgot to mention, its r6 not r15

Also I donā€™t know if we need to mess with the actual script functionality, It only happens when the character respawns.

So the original functionality is gone, probably because your script is trying to use r15 instead of r6. Again, I dont know if we need to change anything other than something related to calibration on respawn.

Let me know if I am wrong
